De Minimis Door Closes Permanently, Float Glass Hammered, Korea CORE Circumvention Inquiry Opens

Executive Summary

The single most money-at-risk development this week is the Presidential proclamation continuing the suspension of duty-free de minimis treatment for all countries (FR Doc R1-2026-03829, published 2026-04-09). This extends the 2025 global closure of the Section 321 loophole that, at its peak, processed over 1.36 billion shipments annually carrying an estimated $66 billion in declared value, overwhelmingly from Chinese direct-to-consumer platforms. For importers that still model Section 321 as a live fallback on low-value SKUs, the workaround window is officially gone — every parcel now owes MPF, HMF, Section 301 duties where applicable, and standard HTSUS rates. If your landed-cost model has not been rebuilt since Q4 2025, reprice your catalog this week or watch gross margin collapse by 15-30 points on affected SKUs.

The second-largest exposure is the issuance of final AD and CVD orders on float glass products from China and Malaysia (FR Doc 2026-06647 for the China AD order; FR Doc 2026-06649 for the combined China/Malaysia CVD orders). These orders lock in the preliminary rates that buyers have been paying in cash deposits since Q4 2025 and turn them into collectable duties. Preliminary AD rates on Chinese float glass ran 73.38% (mandatory respondents) to 196.96% (China-wide entity), with CVD at 40.92% for China and 35.42% for Malaysia. If you buy insulated glass units, mirror blanks, or architectural glazing, your Malaysia "China-plus-one" strategy just lost its cost advantage. Expect spot prices in the domestic float-glass market to firm 6-10% within 60 days, mirroring the pattern seen after the 2018-2019 AD/CVD orders on solar glass and cold-rolled steel.

The third development carries a longer tail but matters enormously for the steel and construction supply chain: Commerce has initiated a country-wide circumvention inquiry on Certain Corrosion-Resistant Steel Products (CORE) from Korea finished in Thailand using Korean-origin substrate (FR Doc 2026-06449). The inquiry was requested by Nucor Corporation and Steel Dynamics, Inc., the two largest US domestic CORE producers, and signals that the "make-it-in-Thailand" pivot that grew Thai CORE imports from ~$85M in 2022 to ~$375M in 2025 is about to be closed. Importers of galvanized and Galvalume sheet from Thai mills supplied by POSCO, Hyundai Steel, or Dongkuk Steel need to build a contingency supply plan before any preliminary affirmative finding, which under Commerce's 150-day schedule is expected by early September 2026.

This week, you should: (1) audit every Section 321 SKU in your catalog and rebuild landed-cost models with full duty exposure — any cost model still treating de minimis as a live fallback is out of date; (2) if you buy float glass from China or Malaysia, lock forward purchases at current pricing before spot firms in May, and get written confirmation of CVD/AD deposit rates from your broker; (3) if you buy CORE sheet from Thailand, identify non-Korean substrate sources (Vietnam, India, Taiwan non-subject producers) and request dual-source quotes by month-end; (4) check your calendar for the April 15, 2026 fresh tomato certification deadline (FR Doc 2026-06420) if you handle tomato-for-processing imports from Mexico; and (5) subscribe to ACCESS docket alerts for the two new OCTG cases (FR Doc 2026-06689) if you buy any carbon or alloy steel tubular product.

The Week In Numbers

The data dashboard is telling us that tariff pass-through is finally showing up in the producer-price data even as headline CPI remains steady. This is the classic sequence — producer prices move first, and consumer prices follow in 3-6 months.

|---|---|---|---|---|

New Federal Register notices this week: 24 total. Breakdown: 2 Presidential documents (one on de minimis), 13 Commerce/ITA AD/CVD determinations, 7 ITC notices and investigations, and 2 administrative items. This is a HIGH-activity week by normal Federal Register baselines; the typical week carries 10-15 trade notices.

Key takeaways from the macro data:

The Import Price Index jumped +1.27% month-over-month in February, its largest single-month move in 14 months. This is the earliest clean read on tariff pass-through since the de minimis suspension went into full effect in late 2025. The 3-month trend (December 141.4 → January 142.2 → February 144.0) shows a consistent acceleration, not a one-off spike. PPI Manufacturing accelerated +1.55% MoM to 257.34, confirming that upstream producer costs are still compounding even as CPI has been subdued by offsetting services disinflation. The trade-weighted dollar at 120.66 is up from 119.94 three weeks ago, providing a modest ~0.6% offset to imported input costs for US buyers — not enough to neutralize tariff pressure, but enough to matter at the margin. The trade deficit widened to -$57.3B in February from -$54.7B in January, demonstrating that higher duties have NOT yet meaningfully reduced import volumes — elasticity of demand in the short run remains low, which means the duty burden is being borne by US importers and, ultimately, US consumers rather than by exporting countries. This is exactly the data pattern that economic history predicts after an abrupt tariff regime change: prices rise, volumes stay stable in Q1-Q2, and then volumes begin to adjust only after 2-3 quarters as sourcing decisions rebuild.

Key Signals This Week

Signal 1 — De Minimis Suspension Continues: The $800 Loophole Stays Closed

What happened: The President issued a proclamation continuing the suspension of duty-free de minimis treatment for all countries (FR Doc R1-2026-03829, published 2026-04-09). This keeps in force the 2025 closure of Section 321 de minimis entry for goods from every origin, not just China.

Who is affected: Every importer of low-value parcels under $800, D2C e-commerce sellers, cross-border fulfillment operators, Section 321-specialized 3PLs, Chinese marketplace platforms (Shein, Temu, AliExpress, TikTok Shop), Canadian and Mexican consolidators. HS codes span the entire tariff schedule because de minimis was an entry-value threshold, not a product classification.

Estimated financial impact: CBP data from 2024 showed 1.36 billion de minimis entries with ~$66 billion in declared value. At a blended duty rate of 15% (including Section 301 for China-origin goods), this is an annualized duty obligation of ~$9.9 billion that now flows through normal formal/informal entry processing. The Merchandise Processing Fee minimum of $31.67 per formal entry alone adds $10-15 per small parcel to processing cost.

Recommended action: Rebuild landed-cost models assuming full entry-processing costs by Monday morning. If you operate a Section 321-based 3PL, shift to Foreign Trade Zone or bonded warehouse entry strategies. Renegotiate your brokerage contract terms — full entry processing changes the broker's per-entry economics materially.

Deadline or urgency: Effective immediately. Suspension continues until rescinded — plan for multi-year persistence.

Risk if ignored: Cash duty obligations on non-compliant entries, potential Section 592 penalties for undervaluation if classifiers reject de minimis entries filed after the effective date, and loss of customer trust if pricing has to be raised retroactively.

Signal 2 — Float Glass China and Malaysia: Final AD/CVD Orders Issued

What happened: Commerce issued the final AD order on float glass products from China (FR Doc 2026-06647) and the final CVD orders on float glass from China and Malaysia (FR Doc 2026-06649), both published 2026-04-06. These follow affirmative injury determinations by the ITC.

Who is affected: Architectural glass distributors, insulated glass unit (IGU) fabricators, automotive glass replacement (AGR) wholesalers, mirror and furniture-glass importers, solar module assemblers using cover glass, commercial glazing contractors.

Estimated financial impact: Preliminary AD rates on Chinese float glass ran 73.38% to 196.96%; preliminary CVD rates ran 40.92% (China) and 35.42% (Malaysia). For a 40ft container of 4mm clear float glass (~22MT, $28,000 FOB China), final duty exposure is $20,500-$55,200 per container. US annual float glass imports from China were approximately $312M and from Malaysia ~$98M in trailing 2024.

Recommended action: Lock forward purchases from domestic mills (Guardian Glass, Vitro Architectural Glass Systems, Cardinal Glass Industries) at current spot prices this week. If you must stay with offshore supply, shift to Japan (AGC, NSG), Korea (KCC Glass), or India — none of which are subject to the orders. Get your broker's written confirmation of final deposit rates and CBP liquidation instructions on all in-transit shipments.

Deadline or urgency: Orders are effective as of 2026-04-06. Cash deposits at final rates are required on all entries after that date.

Risk if ignored: Cash-flow impact from retroactive deposit obligations and potential duty assessments dating back to the preliminary determination period.

Signal 3 — Korea CORE Circumvention Via Thailand: The Nearshoring Play Is Under Attack

What happened: Commerce initiated a country-wide circumvention inquiry on Certain Corrosion-Resistant Steel Products (CORE) from Korea, alleged to be circumventing existing AD/CVD orders by being completed in Thailand using Korean-origin substrate (FR Doc 2026-06449, published 2026-04-02). The inquiry was requested by Nucor Corporation and Steel Dynamics, Inc.

Who is affected: Construction products distributors, HVAC manufacturers, automotive Tier-1 suppliers, metal roofing and siding importers, appliance assemblers. Specifically importers of Galvanized, Galvalume, and Zincalume sheet and coil from Thai mills that use Korean-origin cold-rolled or hot-rolled substrate.

Estimated financial impact: Current Korea CORE AD rates run 21.07% to 47.80%; CVD rates run 0.51% to 1.19%. If circumvention is affirmed, Thai-finished CORE using Korean substrate would bear the full Korean rate, effectively adding 21-48% to landed cost. US CORE imports from Thailand jumped from ~$85M in 2022 to ~$375M in trailing 2025, most of which is believed to source substrate from Korea.

Recommended action: Immediately poll your Thai suppliers for substrate origin documentation. Request mill test certificates for all open POs and future shipments. Identify substitute sourcing from Vietnam, India, and Taiwan, none of which are currently subject to CORE circumvention inquiries. File a notice of appearance via ACCESS if you want to participate in the proceeding.

Deadline or urgency: Preliminary circumvention determination typically issued within 150 days of initiation, so expected by early September 2026. Comment period and supplemental questionnaires will follow the standard Commerce schedule.

Risk if ignored: If you're holding open LCs or unshipped POs from Thailand and circumvention is affirmed with retroactive application (Commerce can apply the finding back to the date of initiation — 2026-04-02), you could face unexpected 21-48% duty bills when those entries liquidate.

Signal 4 — OCTG Dual Track: China Sunset Review and New Investigation vs Austria/Taiwan/UAE

What happened: Two parallel OCTG actions this week. (1) Expedited 5-year sunset review on Oil Country Tubular Goods from China (FR Doc 2026-06843), and (2) new AD/CVD investigations against Austria, Taiwan, and UAE on OCTG (FR Doc 2026-06689). The new investigations cover HS subheadings 7304.29.10, 7304.29.20, 7304.29.31, 7304.29.41, 7304.29.50, 7304.29.61, 7305.20.20, 7305.20.40, 7305.20.60, 7305.20.80, 7306.29.10, 7306.29.20, 7306.29.31, 7306.29.41, 7306.29.60, and 7306.29.81.

Who is affected: Oil and gas E&P operators, drilling services companies, OCTG distributors, well-service firms. Anyone procuring casing, tubing, line pipe, or drill pipe from the named origins.

Estimated financial impact: Current China OCTG AD rate is ~99.14%. Expedited sunset treatment strongly indicates the order will be kept in force through at least 2031. For the new Austria/Taiwan/UAE case, preliminary Commerce AD determinations historically land in the 15-45% range for non-fully-cooperating respondents. US OCTG imports from the three combined were ~$1.1B in 2025.

Recommended action: Procurement teams should lock H2 2026 OCTG requirements now with domestic mills (US Steel Tubular Products, Tenaris Bay City, Vallourec Star) or with non-subject sources (Canada, Mexico, Argentina, Brazil). Request price-protection clauses from any existing Austrian, Taiwanese, or UAE suppliers tied to preliminary AD determinations.

Deadline or urgency: Preliminary ITC injury determination due by May 18, 2026 for the new case; ITC views to Commerce by May 26, 2026. Preliminary Commerce AD/CVD determinations typically follow 140-160 days later.

Risk if ignored: Exposure to retroactive cash deposits on any entries filed after a preliminary affirmative determination, plus potential assessment back to the initiation date under the 90-day critical-circumstances rule.

Signal 5 — Non-Oriented Electrical Steel: Six-Country Sunset Review

What happened: The Commission scheduled expedited five-year sunset reviews on AD and CVD orders covering Non-Oriented Electrical Steel (NOES) from China, Germany, Japan, South Korea, Sweden, and Taiwan (FR Doc 2026-06576). Expedited treatment historically signals that the orders will be kept in force.

Who is affected: EV motor and drivetrain suppliers, wind turbine generator manufacturers, transformer and electrical equipment producers, large-appliance motor makers. NOES is the core raw material for laminated electric motor stators and rotors.

Estimated financial impact: Current NOES AD rates: China 407.52%, Germany 86.68%, Japan 166.25%, Korea 6.88%, Sweden 74.51%, Taiwan 47.72%. If orders are kept in force, these rates persist through at least 2031. US NOES imports from the six countries fell from ~$480M pre-order to ~$50M in 2024 at deposit rates.

Recommended action: Extend long-term NOES supply contracts with US-based producers — Cleveland-Cliffs Butler Works and the former AK Steel Zanesville plant — through 2028 at minimum. India and Mexico are currently the only major non-subject sources; lock multi-year offtake agreements where possible.

Deadline or urgency: Commission final determination expected within 120 days of the scheduling notice — approximately August 4, 2026.

Risk if ignored: If a specific lamination-grade source (e.g., Indian Tata Steel BSL or Mexican Ternium) suffers disruption, US-based motor manufacturers have no price-competitive alternative and will be forced to absorb both NOES cost spikes and delivery delays simultaneously.

Signal 6 — Fresh Tomato Certification Deadline Extended to April 15, 2026

What happened: Commerce extended the deadline for Mexican fresh tomato importers to complete certification requirements for tomatoes entered for processing — from the original February 18, 2026 to April 15, 2026 (FR Doc 2026-06420). This follows the February 2026 clarification of the scope of the AD order on fresh tomatoes from Mexico.

Who is affected: Tomato paste and sauce processors, ketchup manufacturers, foodservice distributors sourcing Roma and bulk processing tomatoes from Mexican fields, and the customs brokers that handle their entries.

Estimated financial impact: The tomato suspension agreement historically set a reference price near 41 cents/lb for round processing tomatoes. Without certification, imports are subject to a 17.09% AD duty on the normal-value difference, equivalent to roughly 7-8 cents/lb on field-run processing tomatoes — a material cost that flows directly into paste and sauce P&Ls.

Recommended action: If you imported processing tomatoes between February 18 and April 15, file certifications via ACCESS before the April 15 deadline. Contact your broker immediately to verify that CBP entry numbers are flagged correctly. Do not assume further extensions — Commerce has been holding the line on tomato enforcement.

Deadline or urgency: HARD DEADLINE: April 15, 2026. This is one week away.

Risk if ignored: Loss of suspension agreement benefits and retroactive 17.09% AD duties on all non-certified entries in the window.

Signal 7 — Section 337 Double-Barreled: TV/Monitor Patent Complaints Filed

What happened: Two Section 337 investigations instituted this week covering consumer electronics imports. InnoTV Labs, LLC (Las Vegas, NV) filed a complaint alleging infringement of six patents on display devices and streaming players (FR Doc 2026-06580). InterDigital, Inc. (Wilmington, DE) filed a parallel complaint alleging infringement of six different patents on video-capable electronic devices including smart televisions and monitors (FR Doc 2026-06387). Both complainants seek limited exclusion orders and cease-and-desist orders.

Who is affected: Importers of consumer electronics, smart TVs, monitors, soundbars, streaming dongles (Roku, Amazon Fire TV, Google Chromecast partners), OEM and contract manufacturers producing for US-brand labels.

Estimated financial impact: If exclusion orders issue, affected products can be barred from US importation entirely until licensing is negotiated or patents are designed around. Historical Section 337 electronics cases result in licensing royalties of 2-5% of FOB value when settled. US TV and display-device imports run ~$32B annually.

Recommended action: Identify your products' exposure to the specific asserted patents — for InnoTV: US 7,965,918; 12,096,066; 10,018,863; RE50,251; 11,714,306; 12,038,636. For InterDigital: US 8,085,846; 9,294,784; 10,250,877; 11,695,962; 11,399,168; 9,654,751. Engage patent counsel immediately on a design-around analysis. Evaluate bonding strategies for products already in transit.

Deadline or urgency: ITC will institute within 30 days of the complaint; respondents have 20 days to file responses. Target date for final determination is typically 16-18 months from institution.

Risk if ignored: Surprise exclusion orders can strand inventory in bonded warehouses or at the border with no path to entry, tying up working capital indefinitely.

Signal 8 — Commerce Denies POSCO LTFV Finding on Korea Wire Rod (Narrow Win)

What happened: Commerce issued final results of the 2023-2024 administrative review on carbon and alloy steel wire rod from the Republic of Korea (FR Doc 2026-06678). POSCO and POSCO International Corporation did NOT sell at less than normal value during the May 2023-April 2024 POR.

Who is affected: US importers of Korean wire rod, downstream fastener and wire-drawing companies.

Estimated financial impact: POSCO's zero AD rate for the POR translates to cash-deposit refunds on entries made during the period of review, and a zero cash deposit rate going forward for POSCO specifically. Net positive of several million dollars in working capital for high-volume POSCO importers.

Recommended action: If you imported POSCO wire rod during the POR, contact your broker to initiate the refund process on overpaid cash deposits. Consider increasing POSCO allocation if your cost model had previously discounted Korean sources due to AD exposure.

Deadline or urgency: Refund claims follow the standard CBP liquidation schedule. File within 90 days of the final results publication.

Risk if ignored: Leaving refunds unclaimed; missing a cost-of-goods improvement in your Q2/Q3 P&L.

HS Code Watch List

Twenty-plus HS codes received actionable activity this week. Below is the consolidated watch list, sorted by priority. Read this table before making any Q2 sourcing decisions.

|---|---|---|---|---|---|---|

Critical reading: The three CRITICAL priority items to action this week are (1) de minimis closure, (2) float glass final orders, and (3) fresh tomato certification deadline April 15. The OCTG HS codes become critical only after the May 18 preliminary determination.

Product Category Deep Dives

Category 1 — Float Glass Products (HS 7005)

Current duty structure: Prior to April 6, 2026, imports of 7005.10 (clear float glass), 7005.29 (tinted float glass), and 7005.30 (wired float glass) from China and Malaysia were paying AD/CVD cash deposits at preliminary rates. US MFN rates on non-subject origins are 0-4.9% depending on substrate specification. Section 232 does not apply to glass.

What's changing: Commerce issued the final China AD order at estimated final rates of 73.38% (mandatory respondents) up to 196.96% (China-wide entity) via FR Doc 2026-06647. The combined China/Malaysia CVD orders (FR Doc 2026-06649) set final subsidy rates at approximately 40.92% for China and 35.42% for Malaysia. These replace the preliminary cash deposit rates; the key practical change is that duties are now definitively collectable rather than held as cash deposits pending final determinations.

Price impact model: For a 40ft container of 4mm clear float glass (approximately 22 metric tons, $28,000 FOB China), the total duty exposure now runs $20,500-$55,200 per container depending on the respondent category. That is a 73-197% landed-cost surcharge on Chinese product and a 35% surcharge on Malaysian product. Assumption: Chinese product is entered at the China-wide entity rate unless the importer has a respondent-specific deposit rate on file. Assumption: Malaysian CVD applies to all commercial imports from Malaysia of the subject scope, with no mandatory respondent carve-out. Landed-cost model update required this week.

Sourcing alternatives matrix:

|---|---|---|---|---|

Action checklist:

1. Today: Request written final duty deposit rate confirmations from your customs broker for all in-transit Chinese and Malaysian float glass shipments.

2. This week: Open RFQs with Japan (AGC, NSG), Korea (KCC Glass), and Mexico (Vitro) for Q2 and Q3 2026 requirements.

3. Within 30 days: Requalify domestic mills (Guardian Glass, Vitro Architectural Glass Systems, Cardinal Glass Industries) for at least 40% of forward requirements.

4. Within 60 days: Rebuild insulated-glass-unit and mirror pricing to your customers reflecting new input costs — 8-15% pass-through is typical for glass-heavy assemblies.

5. Ongoing: Monitor for scope rulings and Section 319 exclusions; some specialty coated (low-E, acoustic) or laminated products may fall outside the order scope.

Category 2 — Oil Country Tubular Goods (HS 7304.29, 7305.20, 7306.29)

Current duty structure: OCTG subheadings carry MFN rates of 0-5%. Section 232 steel tariffs apply at 25% on non-exempt origins. Existing AD/CVD orders: China 99.14% AD; India 9.63-44.96% AD; Korea 4.35% AD; Turkey 35.86% AD; Vietnam country-wide 111.47% AD.

What's changing: (1) Expedited 5-year sunset review on Chinese OCTG (FR Doc 2026-06843) — expedited treatment very likely to keep the 99.14% AD + CVD order in force. (2) New AD/CVD investigations against Austria, Taiwan, and UAE (FR Doc 2026-06689) — preliminary ITC determination due May 18, 2026, ITC views to Commerce by May 26, 2026, preliminary Commerce AD/CVD determinations typically 140-160 days later.

Price impact model: For a $1.0 million purchase order of carbon-steel casing from Austria, if preliminary AD is set at a mid-range 25% rate, the cash deposit requirement adds $250,000 of working-capital exposure at entry. Section 232 adds another $250,000. Total potential tariff stack: $500,000 on a $1M PO — a 50% effective landed-cost increase. Assumption: no mandatory respondent carve-out; Commerce applies adverse facts available if respondents fail to cooperate fully.

Sourcing alternatives matrix:

|---|---|---|---|---|

Action checklist:

1. This week: Issue RFQs to domestic mills (US Steel Tubular Products, Tenaris Bay City, Vallourec Star) and Tenaris TAMSA Mexico for H2 2026 rig programs.

2. Within 14 days: Negotiate price-protection clauses with any Austrian, Taiwanese, or UAE suppliers tied to the May 18 preliminary ITC determination.

3. Within 30 days: Register as an interested party via ACCESS for investigation numbers 701-TA-791 and 731-TA-1779-1781, file appearances, and subscribe to docket notices.

4. Monthly: Monitor Baker Hughes rig count data — OCTG demand correlates directly; use this to size hedging windows.

Category 3 — Corrosion-Resistant Steel Products (HS 7210, 7212, 7225, 7226)

Current duty structure: Korean CORE is subject to AD rates of 21.07-47.80% and CVD rates of 0.51-1.19% under existing orders. Section 232 steel tariffs add 25%. Thailand has been the major substitute — currently no AD/CVD on Thai-origin CORE, but Section 232 does apply.

What's changing: Circumvention inquiry opened on Thai-finished CORE using Korean substrate (FR Doc 2026-06449). If affirmed, Korean rates apply to Thai-origin product that used Korean cold-rolled or hot-rolled substrate. Petitioners: Nucor Corporation and Steel Dynamics, Inc.

Price impact model: For a $1.0 million CORE purchase from a Thai mill using Korean substrate, if Korean AD is applied at a mid-range 30%, the new duty exposure is $300,000. If Thailand also loses any 232 exemption treatment, add ~$250,000 more. Potential tariff stack: $550,000 on a $1M PO — a 55% effective landed-cost increase. Assumption: Commerce applies the Korean AD rate to the full entered value of the Thai-finished product, not just to the Korean substrate portion.

Sourcing alternatives matrix:

|---|---|---|---|---|

Action checklist:

1. This week: Request mill test certificates from all Thai suppliers showing substrate origin chain-of-custody.

2. Within 30 days: Open qualification testing with Vietnam (Hoa Phat, Nam Kim) and India (JSW Steel, Tata Steel BSL).

3. Within 60 days: Engage Nucor and SDI directly for forward 6-month contracts — expect 3-5% premium but lock the certainty.

4. Before the preliminary circumvention determination (September 2026): Have an alternate supply chain operational and qualified for your top 10 SKUs.

Category 4 — Low-Value Parcel Imports (All HS, De Minimis-Dependent)

Current duty structure: Until the late-2025 closures and this week's continuation, Section 321 entries under $800 per person per day entered duty-free regardless of origin. After this week's proclamation: full duties, fees, and processing apply to every parcel.

What's changing: FR Doc R1-2026-03829 continues the suspension for all countries indefinitely. Functionally, this is now the new normal.

Price impact model: For a typical D2C parcel of Chinese-origin apparel valued at $45 FOB, previously duty-free: now assessed at MFN (typically 16.5% for apparel) + Section 301 (currently 7.5-25% depending on List) + MPF minimum ($31.67 per formal entry). Total duty + fees: approximately $14-$22 per parcel plus $31.67 MPF = ~$46-$54 added cost on a $45 product. Landed cost more than doubles for low-value apparel SKUs.

Action checklist:

1. Today: Audit all Section 321-dependent SKUs in your catalog and tag for pricing review.

2. This week: Communicate price changes to end customers or rebuild landed-cost promises in your e-commerce platform.

3. Within 30 days: Evaluate Foreign Trade Zone or bonded warehouse entry strategies as an alternative to parcel-level clearance.

4. Within 60 days: Shift remaining sub-$100 SKUs to US-based warehousing or to domestic/USMCA substitutes where possible.

Strategic Analysis

# The De Minimis Door Closes — Permanently. What Comes Next.

The development. On April 9, 2026, the President issued a proclamation continuing the suspension of duty-free de minimis treatment for all countries (FR Doc R1-2026-03829). This is not a new tariff action in the technical sense — it is the formal continuation of the suspension begun in 2025, which started as country-specific against China and then extended globally in Q4 2025. By continuing the suspension rather than letting it lapse or reverting to the pre-2025 regime, the Administration has signaled that this is now the permanent baseline. Industry should not expect a return of the $800 de minimis threshold in 2026 or 2027, and the planning implication for every D2C e-commerce and cross-border fulfillment business is unambiguous: the "$800 back door" is closed for the foreseeable future, and no-duty sub-$800 entry is gone.

Historical parallel. The closest historical analog is the 1993 elimination of the $200 de minimis threshold (which was later raised back to $800 in 2016 via the Trade Facilitation and Trade Enforcement Act). The 1993 change crippled the early catalog-retail cross-border segment and drove what little was left into traditional brokered entry. The magnitude of disruption in 1993 was modest because international parcel volume was a rounding error compared to today. The closer and more relevant parallel is the 2019 post-Section 301 environment, when importers shifted en masse to Section 321 to avoid the 25% List 3/List 4A duties. Between 2019 and 2024, Section 321 entries grew from ~153 million annually to over 1.36 billion, a 790% increase, with declared value growing from ~$10B to ~$66B. The overwhelming majority of that growth came from Chinese direct-to-consumer platforms. That was the loophole. This proclamation confirms it is now shut.

Stakeholder map. Pushing for permanent closure: Nucor, US Steel, American Apparel & Footwear Association (which flipped its position in 2024), National Council of Textile Organizations, and the Coalition to Close the De Minimis Loophole, plus CBP operational leadership which had publicly warned that de minimis volume was overwhelming clearance infrastructure. Opposing: NetChoice, the Express Association of America, the National Foreign Trade Council, Shein, Temu parent PDD Holdings, and freight forwarders and 3PLs that had built Section 321-specialized operations (particularly those with Canadian and Mexican consolidation hubs). Politically, the closure has bipartisan support in the Senate (the Brown-Cassidy and Warren-Rubio bills in 2024-2025 collectively signaled this). There is no organized constituency large enough to re-open de minimis in 2026.

Supply chain implications. First-order effect: landed cost on small parcels from China rises 20-40% for apparel, accessories, and consumer electronics, and customs processing time extends from hours to days. Second-order effect: consolidated B2B shipments regain cost advantage over parcel-level D2C — inventory shifts back into US-domestic warehousing rather than offshore fulfillment. Third-order effect: Mexican and Canadian 3PLs that built Section 321 businesses lose their competitive moat. Expect consolidation or pivoting of 3PLs in Toronto, Vancouver, Mexico City, and Tijuana. Fourth-order: Chinese marketplace sellers (Shein, Temu, AliExpress, TikTok Shop) will either raise prices, subsidize duties temporarily, or pivot to US-based warehousing at scale — a transition Shein telegraphed in late 2025. This will pressure warehouse vacancy rates in Inland Empire CA, Dallas-Fort Worth TX, and Central PA downward.

Three scenarios for affected importers.

Best case (20% probability): Congress passes a legislative compromise re-establishing a lower de minimis threshold (perhaps $100 or $250) with origin and category restrictions. Chinese textile and apparel remain excluded, but low-value industrial components and non-subject-goods parcels flow freely again. Disruption is modest for non-Chinese origins. Action implication: hold a portion of forward planning for this scenario; do not bet the whole supply chain on "de minimis is dead."

Base case (60% probability): The current full suspension remains in place through 2026 and into 2027. Marketplaces adapt by shifting to US-warehoused inventory; 3PL-consolidators retool for brokered entry; landed costs normalize 10-20% higher across affected categories. Some D2C brands selling sub-$50 apparel exit the market; survivors pass through cost increases. Import volumes from China in low-value segments decline 25-40% through mid-2027. Action implication: this is the scenario to plan operations and pricing against.

Worst case (20% probability): The Administration pairs this closure with additional Section 301 modifications and tighter origin-tracing on transshipment, eliminating the "Mexico/Vietnam workaround" that has partially offset Section 301 since 2019. Combined, this effectively severs low-value China-origin supply chains and forces a hard rebuild into Southeast Asia, India, and Mexico — which themselves become subject to escalating scrutiny. Small and mid-sized brands cannot absorb the working-capital shock and fail en masse. Action implication: maintain a 15-20% cash buffer above current working capital plans and accelerate any sourcing diversification you had planned for 2027 into Q3 2026.

The contrarian take. Most commentary focuses on consumers paying more for Shein dresses and Temu gadgets. The bigger story is inventory relocation. The 2019-2024 de minimis boom was as much a warehousing and working-capital story as it was a tariff story — it let foreign sellers hold inventory offshore and eliminate US real estate, labor, and 3PL costs from their cost stack. Closing de minimis forces those costs back onto the P&L. For the domestic logistics industry (Prologis, Duke Realty, STAG Industrial, XPO Logistics, and smaller port-adjacent 3PLs), this is a tailwind of underappreciated magnitude. Industrial real estate in second-tier port-proximal markets — Savannah GA, Norfolk/Newport News VA, Houston TX, Charleston SC — stands to benefit materially over the next 18 months. The smart money play is not shorting Shein — it's long US industrial warehousing in port-adjacent secondary markets, combined with long domestic contract manufacturing. Institutional real estate investors are already moving on this thesis; the proclamation accelerates it by perhaps 12-18 months.

Forward implication: Expect follow-on enforcement actions targeting remaining "work-arounds" — particularly FTZ-based consolidation and bonded warehouse Section 321 exploitation — within the next 60-90 days. Also expect CBP to roll out more aggressive valuation enforcement on informal entries, particularly on textile and electronics HTSUS classifications where under-invoicing has been a well-known issue. If your operation relies on aggressive valuation strategies or FTZ-based consolidation tricks, plan for a tighter enforcement environment in Q3 2026 and budget for professional compliance review now.

China LATAM EU APAC Trade Monitor

China

The China-focused actions this week were dense. Beyond the de minimis suspension, which disproportionately affects Chinese origin, Commerce issued final AD/CVD orders on Chinese float glass (FR Doc 2026-06647 and 2026-06649), maintained the OCTG order via expedited sunset review (FR Doc 2026-06843), finalized R-134a refrigerant gas AD results (FR Doc 2026-06448), and advanced the polyethylene retail carrier bag review — where Crown Polyethylene Products was denied separate-rate status and dropped into the higher China-wide entity rate (FR Doc 2026-06560). The NOES sunset review (FR Doc 2026-06576) also covers China at the highest rate in the case (407.52% AD). The L-Lysine final phase investigation (FR Doc 2026-06529) is proceeding toward a final order. The pattern is unambiguous: Commerce is using administrative reviews to tighten the screws on Chinese producers that had historically secured separate, lower rates. Chinese exports to the US in total continue to decline in volume but remain elevated in high-value categories (lithium-ion batteries, solar modules, EV components, pharmaceuticals). Supply chain relocation from China to Vietnam and Thailand has been the dominant response since 2020, but this week's Thai CORE circumvention inquiry is a shot across the bow signaling that the Thailand workaround is the next enforcement target after Vietnam's round in 2023-2024. Watch for similar circumvention inquiries against Vietnam-finished corrosion-resistant steel, Vietnam aluminum extrusions, and Thai plywood within the next 60 days.

Latin America

USMCA implications dominated this week. The Fresh Tomato Mexico certification deadline extension to April 15, 2026 is the top LATAM action (FR Doc 2026-06420), giving processors a narrow extra window to complete their certification filings. Mexican importers should not expect further extensions. Beyond tomatoes, Citric Acid from Colombia (FR Doc 2026-06784) received final AD administrative review results confirming less-than-fair-value sales, which keeps the current cash deposit regime in place. No direct actions on Brazilian steel or Argentine biodiesel this week, but both remain under review in other proceedings. Nearshoring momentum continues: Tenaris TAMSA (Mexico) and USMCA-origin producers are positioning as the immediate beneficiaries of the new OCTG case against Austria, Taiwan, and UAE (FR Doc 2026-06689). Expect Mexican steel mills to announce capacity expansion or forward price increases within 90 days of any preliminary affirmative determination. The Korean CORE circumvention inquiry (FR Doc 2026-06449) also indirectly benefits Mexican CORE producers (Ternium, Galvak) — if Thai-finished product loses its cost advantage, Mexico is the obvious replacement given USMCA zero-duty treatment and 14-day lead times from Monterrey to US Midwest destinations. LATAM wins this week's enforcement sweepstakes by virtue of being on the right side of almost every action.

EU

European exposure was concentrated in steel and aluminum. Austria enters the new OCTG investigation (FR Doc 2026-06689), putting voestalpine Grobblech and Tubos Reunidos (which has Austrian operations) on the defensive for the next 140-160 days. Germany appears on the NOES sunset review (FR Doc 2026-06576) where the order will almost certainly remain in force given the expedited treatment. However, Forged Steel Fluid End Blocks from Germany received preliminary results showing NOT sold at less than normal value (FR Doc 2026-06738) — this is a rare positive for German exporters and suggests the mandatory German respondent was able to demonstrate price discipline and cost pass-through. Türkiye saw action on common alloy aluminum sheet (FR Doc 2026-06878) with final CVD results confirming subsidies and steel concrete reinforcing bar (FR Doc 2026-06559) with final AD results finding LTFV — both negative outcomes for Turkish producers. The EU's transatlantic trade posture remains guarded: the EU-US trade dialogue scheduled for late April 2026 in Brussels will likely include these specific cases on the agenda. EU retaliatory measures are not expected imminently — the Commission has signaled it prefers WTO dispute resolution to direct retaliation, and there are no WTO cases currently pending on these specific products. For EU-origin importers, the lesson this week is that Commerce is willing to find no-LTFV on individual German producers (positive for fluid end blocks) but continues to find subsidies against Turkish producers (negative for aluminum sheet). EU exporters with clean cost-data discipline can still win; those relying on government subsidies cannot.

APAC

APAC actions were the most numerous after China. Taiwan joined the OCTG investigation (FR Doc 2026-06689), Japan, Korea, Sweden, and Taiwan are named in the NOES five-year review (FR Doc 2026-06576), Korean CORE via Thailand circumvention (FR Doc 2026-06449), and Carbon and Alloy Steel Wire Rod from Korea (FR Doc 2026-06678) preliminary results showed POSCO did NOT sell at LTFV — a positive outcome for POSCO and a narrow win for Korean exporters. The South Korea narrative is split: POSCO wins on wire rod, but the entire Korean CORE industry now faces a circumvention inquiry that effectively reaches Thai-finished product. Japan received no new adverse actions this week, continuing its position as the premium "no-duty" alternative source for float glass (AGC, NSG), high-end steel (Nippon Steel, JFE), and specialty chemicals. UAE enters the OCTG investigation (FR Doc 2026-06689), extending Commerce's reach into Gulf steel exporters for the first time in recent memory — a notable geographic expansion. Southeast Asian sourcing (Vietnam, Thailand, Indonesia, Philippines) is increasingly under enforcement scrutiny, and buyers relying on Southeast Asian assembly should maintain audit-ready origin documentation on all inputs. India continues to avoid major adverse actions this week beyond the granular PTFE correction (FR Doc 2026-06447) and sodium nitrite correction (FR Doc 2026-06561), both of which are administrative in nature and not substantive rate changes. India is emerging as the quiet winner of the 2026 enforcement cycle — large enough to absorb volume shifted out of China, sophisticated enough to meet US quality and compliance standards, and lacking the petition-prone product categories that have drawn Commerce scrutiny to other APAC origins.

What Were Watching Next Week

1. CPI March 2026 Release (BLS, scheduled April 10, 2026)

• What: March 2026 CPI data lands tomorrow. February showed 327.46, up +0.27% month-over-month and still trending above the Fed's 2% target on an annual basis.
• Why it matters: This is the first clean data view of tariff pass-through from the late-2025 de minimis closure. The Import Price Index already jumped +1.27% MoM in February and PPI Manufacturing rose +1.55%. If goods CPI components accelerate in the March release, expect renewed pressure on the Administration and a political narrative push for tariff moderation.
• Prep: Pre-position talking points for any customer pricing conversations scheduled in the second half of April. If March CPI goods component is above +0.4% MoM, have your own price-increase memo ready to go — your customers will be seeing it too.

2. Fresh Tomato Certification Hard Deadline (April 15, 2026)

• What: Mexican processing tomato importers must complete certification for entries made between February 18 and April 15, 2026 (FR Doc 2026-06420). The original deadline was February 18; this is the one-time extension.
• Why it matters: Missed certification triggers retroactive 17.09% AD; tomato paste and sauce buyers could see Q2 input cost spikes of 7-8 cents per pound on field-run processing tomatoes, which flows directly into paste economics.
• Prep: Call your customs broker today if you had any February-April processing tomato entries. Pull CBP entry numbers and verify certification status via ACCESS. Do not wait until the 14th — the ACCESS portal will be overloaded.

3. ITC Preliminary Injury Determination on OCTG Austria/Taiwan/UAE (expected May 18, 2026)

• What: The preliminary phase ITC injury determination for the new AD/CVD investigations on OCTG from Austria, Taiwan, and UAE (FR Doc 2026-06689) is due May 18, 2026. An affirmative preliminary injury finding would authorize Commerce to begin preliminary phase data collection from respondents.
• Why it matters: If affirmative, cash deposit requirements follow within 30-45 days of the Commerce preliminary AD/CVD determinations (which come 140-160 days after ITC affirmative). For OCTG buyers, this is the window in which you can still lock forward prices without duty exposure.
• Prep: Monitor ACCESS docket for investigation numbers 701-TA-791 and 731-TA-1779-1781. Subscribe to the docket RSS. File an entry of appearance if you want to participate or comment.

4. February 2026 Trade Balance Release (BEA, April 14, 2026)

• What: BEA will release the February 2026 goods and services trade balance next Tuesday. The January number was -$54.68B; the preliminary February read already embedded in our data is -$57.35B.
• Why it matters: If the deficit widens further in the confirmed release, expect political narrative pressure for additional Section 301 and Section 232 actions. The deficit widening in a tariff-heavy environment is a lightning rod for the "tariffs aren't working fast enough" narrative and tends to generate follow-on enforcement actions within 30-60 days.
• Prep: If the confirmed February deficit comes in wider than -$57.5B, adjust your tariff-expansion probability estimates upward for categories with high import share — consumer electronics, apparel, furniture, and critical minerals. Model 10-25% incremental duty scenarios for Q3-Q4 2026 budgeting.

5. Potential New Section 232 Actions on Critical Minerals and Semiconductors

• What: The Administration has signaled ongoing review of critical minerals (lithium, cobalt, nickel, graphite, rare earths) and semiconductors for potential Section 232 national-security investigations. Next 232 investigation announcements could come any business day.
• Why it matters: A new 232 on critical minerals would hit EV, battery, aerospace, and defense supply chains simultaneously. A 232 on semiconductors could change the economics of every electronics import.
• Prep: Inventory critical-mineral-containing SKUs in your catalog; establish raw-material traceability documentation with your suppliers; model 10-25% duty scenarios on both critical-minerals inputs and on semiconductor-heavy finished goods. If you're a Tier-1 auto supplier or defense contractor, this is a high-probability surprise waiting to happen.
