De Minimis Suspension Continues for All Countries as Commerce Launches PTMEG and OCTG Investigations Across 8 Nations

Executive Summary

As of April 13, 2026, the U.S. trade enforcement apparatus has escalated across multiple fronts simultaneously, with 24 new Federal Register actions in a single week targeting steel, chemicals, consumer electronics, and agricultural products from over a dozen countries. The Tariff Tracker Desk identifies three developments demanding immediate attention from importers and procurement teams this Monday morning.

The headline action is the Presidential Document R1-2026-03829, continuing the suspension of duty-free de minimis treatment for all countries. This executive action, published April 9, confirms that the $800 de minimis threshold remains suspended — a seismic shift for e-commerce sellers and small importers who relied on this provision for duty-free clearance of low-value shipments. Combined with the five new antidumping duty investigations initiated this week covering products from China, South Korea, Taiwan, Vietnam, Austria, and the UAE, the compliance burden on importers has reached its highest level since the Section 301 tariff escalation of 2018-2019.

The macro backdrop intensifies the pressure: as of February 2026, the Import Price Index has surged to 144.0 (up 1.26% month-over-month), PPI Manufacturing jumped to 257.34 (up 1.55% MoM), and the trade deficit widened to $57.3 billion from $54.7 billion in January. The Trade Weighted Dollar Index has eased to 120.66 as of April 3, offering a marginal buffer for exporters but amplifying landed costs for importers of steel and industrial inputs.

This week, you should: (1) Audit all shipments currently relying on de minimis exemptions and reclassify for formal entry immediately; (2) Review supply chains for PTMEG (HS 3907.29.00, 2932.11.00) and OCTG (HS 7304-7306 subheadings) as new AD/CVD investigations will trigger preliminary duty deposits within 45 days; (3) Verify steel sourcing documentation for any product transiting Mexico or Turkiye, given the continuation of rebar AD/CVD orders under FR Doc 2026-07109.

The Week In Numbers

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

Key trend: The three-month trajectory on the Import Price Index (140.8 → 142.2 → 144.0) confirms a sustained acceleration in import costs, driven by rising tariff burdens and commodity price pressures. Meanwhile, the CPI's jump to 330.29 in March 2026 — a $3.83-point increase from February — signals that tariff-driven cost increases are transmitting through to consumer prices. The falling dollar compounds the problem: importers are paying more per unit of foreign currency just as duty rates are climbing.

Key Signals This Week

Signal 1: De Minimis Suspension Extended to All Countries

• What happened: Presidential Document R1-2026-03829, published April 9, 2026, formally continues the suspension of duty-free de minimis treatment (the $800 threshold under 19 USC 1321) for imports from all countries. This extends and broadens earlier suspensions that initially targeted only China.
• Who is affected: E-commerce sellers importing low-value goods, direct-to-consumer brands using fulfillment from overseas warehouses, small importers of consumer electronics, apparel, and accessories under HS Chapters 61-63, 84-85, and 42. Platforms like Temu, Shein, and AliExpress face structural cost increases.
• Estimated financial impact: The U.S. previously processed an estimated 1 billion de minimis shipments annually. At an average duty rate of 5-25%, this suspension could add $15-40 billion in aggregate duty liability across the e-commerce sector.
• Recommended action: (1) Immediately classify all sub-$800 shipments for formal entry; (2) Establish customs broker relationships if currently self-clearing; (3) Model the duty impact on your top 20 SKUs by volume and reprice accordingly.
• Deadline or urgency: Effective immediately — this is a continuation, not a new proposal.
• Risk if ignored: Shipments arriving without formal entry declarations face seizure at port and potential penalties of up to 4x the unpaid duties.

Signal 2: PTMEG Antidumping Investigations from Four Countries

• What happened: The ITC initiated antidumping duty investigations (Nos. 731-TA-1782-1785) on polytetramethylene ether glycol (PTMEG) from China, South Korea, Taiwan, and Vietnam (FR Doc 2026-07072, published April 13). PTMEG is classified under HS 3907.29.00 and 2932.11.00.
• Who is affected: Manufacturers of spandex, polyurethane elastomers, thermoplastic polyurethane (TPU), and specialty coatings. Key downstream industries include apparel, automotive interiors, medical devices, and footwear.
• Estimated financial impact: PTMEG imports from these four countries totaled approximately $380 million in 2025. Preliminary duties of 15-45% could add $57-171 million in annual costs to the supply chain.
• Recommended action: (1) Identify alternative PTMEG suppliers in non-investigated countries (Japan, Germany, UK); (2) Review contracts with current suppliers for price adjustment clauses; (3) Submit pre-hearing briefs to the ITC by the comment deadline if you are a downstream user opposing duties.
• Deadline or urgency: ITC preliminary determination due by May 26, 2026. Views transmitted to Commerce by June 2, 2026.
• Risk if ignored: Preliminary duties could be retroactively applied to all entries 90 days before the petition filing date, potentially catching current shipments.

Signal 3: OCTG Investigations — New Origins Plus China Review

• What happened: Two simultaneous OCTG actions: (a) New AD/CVD investigations on OCTG from Austria, Taiwan, and UAE (FR Doc 2026-06689, Inv. Nos. 701-TA-791, 731-TA-1779-1781), covering HS subheadings 7304.29, 7305.20, and 7306.29; (b) Expedited five-year review of existing AD/CVD orders on OCTG from China (FR Doc 2026-06843), signaling Commerce expects orders to continue.
• Who is affected: Oil and gas operators, pipeline contractors, energy infrastructure companies, and OCTG distributors. The U.S. consumes approximately $12 billion in OCTG annually.
• Estimated financial impact: Current OCTG duties on Chinese product range from 36.53% to 99.14% (AD) plus 15.87% to 29.57% (CVD). Extension of similar rates to Austrian, Taiwanese, and UAE sources could raise landed costs by $800M-$1.5B industry-wide.
• Recommended action: (1) Audit your OCTG supply chain for exposure to Austria, Taiwan, and UAE sources; (2) Lock in pricing with domestic mills before preliminary duties are imposed; (3) Evaluate Japanese and Korean OCTG as alternative sources not currently under investigation (though Korea faces separate hot-rolled steel actions).
• Deadline or urgency: ITC preliminary determination by May 18, 2026. Views to Commerce by May 26, 2026.
• Risk if ignored: Preliminary duty deposits will be required on all entries from investigated countries once Commerce issues its preliminary determination, typically within 140 days of initiation.

Signal 4: Steel Rebar Orders Continued — Mexico and Turkiye Locked In

• What happened: Commerce published continuation notices for both AD and CVD orders on steel concrete reinforcing bar (rebar) from Mexico and the Republic of Turkiye (FR Doc 2026-07109). The ITC and Commerce both found revocation would likely lead to continuation or recurrence of dumping and injury.
• Who is affected: Construction companies, rebar distributors, infrastructure contractors, and developers. Rebar is a critical input for residential, commercial, and infrastructure construction under HS 7213-7214.
• Estimated financial impact: U.S. rebar consumption exceeds $6 billion annually. Continued duties maintain a price floor approximately 15-30% above free-trade levels, adding an estimated $900M-$1.8B in annual construction costs.
• Recommended action: (1) Factor continued duty levels into 2026-2027 project bids; (2) Explore domestic sourcing or Turkish alternatives through certified steel service centers with established entry compliance; (3) For Mexican-sourced rebar, ensure USMCA origin documentation is airtight — circumvention scrutiny is intensifying.
• Deadline or urgency: Orders are now indefinitely continued until the next sunset review.
• Risk if ignored: Bidding on construction projects without accounting for sustained duty levels risks margin erosion of 8-15% on steel-intensive contracts.

Signal 5: Wooden Bedroom Furniture from China — Preliminary Results

• What happened: Commerce issued preliminary results for the 2024 administrative review of the AD order on wooden bedroom furniture from China (FR Doc 2026-07114). Eleven companies failed to establish separate rate eligibility and are subject to the China-wide entity rate. Eighteen companies had their reviews rescinded.
• Who is affected: Furniture importers, retailers (brick-and-mortar and e-commerce), and bedroom furniture distributors sourcing from China. Covers HS 9403.50.
• Estimated financial impact: The China-wide AD rate on wooden bedroom furniture has historically been 216.01%, effectively prohibitive. Companies losing separate rate status face this rate on all entries during the POR (January 1 - December 31, 2024).
• Recommended action: (1) Verify whether your Chinese furniture supplier has separate rate status; (2) If not, immediately source from Vietnam, Indonesia, or Malaysia — the primary alternative origins; (3) Review all 2024 entries for potential retroactive duty liability.
• Deadline or urgency: Comment period on preliminary results — check FR Doc for exact deadline, typically 30 days from publication.
• Risk if ignored: Liquidation at the 216.01% China-wide rate would make most Chinese bedroom furniture financially unviable, stranding any inventory imported during the POR.

Signal 6: Non-Oriented Electrical Steel (NOES) — Expedited Sunset Reviews

• What happened: The ITC scheduled expedited five-year reviews on AD/CVD orders covering NOES from China, Germany, Japan, South Korea, Sweden, and Taiwan (FR Doc 2026-06576). The expedited nature signals that domestic industry participation is strong and revocation is unlikely.
• Who is affected: Manufacturers of electric motors, transformers, generators, and EV drivetrain components. NOES is essential for the energy transition and EV supply chain.
• Estimated financial impact: U.S. NOES imports are approximately $1.2 billion annually. Continued orders maintain duties of 50-200% on Chinese NOES and 5-30% on other origins.
• Recommended action: (1) For EV and renewable energy manufacturers, evaluate domestic NOES capacity (Cleveland-Cliffs, AK Steel); (2) File pre-hearing statements if you are a downstream user dependent on imported NOES; (3) Budget for continued duty-elevated pricing through at least 2031.
• Deadline or urgency: Expedited review completion expected within 120 days.
• Risk if ignored: Supply chain plans assuming duty reduction or revocation are almost certainly wrong — plan accordingly.

Signal 7: Section 337 Investigations — Screen Protectors and Display Devices

• What happened: Two new Section 337 investigations at the ITC: (a) Screen protectors and application systems (FR Doc 2026-07073), filed by Belkin International citing patents 10,675,817, 10,782,746, and 11,772,320; (b) Display devices and streaming players (FR Doc 2026-06580), filed by InnoTV Labs citing six patents.
• Who is affected: Importers and sellers of phone screen protectors, tablet screen protectors, streaming devices (Roku-type), smart TVs, and display components.
• Estimated financial impact: Section 337 investigations can result in exclusion orders banning infringing products from the U.S. entirely. The screen protector market alone is $1.5 billion annually in the U.S.
• Recommended action: (1) Check if your screen protector or display device suppliers' products are named in the complaints; (2) Consult IP counsel to assess infringement risk; (3) Identify alternative non-infringing products or licensed suppliers.
• Deadline or urgency: Initial determination typically within 12-15 months of institution, but temporary exclusion orders can be issued within weeks if requested.
• Risk if ignored: Products subject to an exclusion order will be refused entry at the border by CBP — no duty payment option, just seizure.

Product Category Deep Dives

Deep Dive 1: Steel Products — The Tightening Vise

Current duty structure: As of April 13, 2026, steel products face the most layered duty regime in U.S. trade history. OCTG from China carries AD rates of 36.53-99.14% plus CVD rates of 15.87-29.57% (FR Doc 2026-06843). Steel rebar from Mexico and Turkiye faces continued AD/CVD orders (FR Doc 2026-07109). Hot-rolled steel from Japan is under review with preliminary LTFV findings (FR Doc 2026-07008), while Korean hot-rolled steel faces preliminary CVD findings (FR Doc 2026-07001). Non-oriented electrical steel from six countries faces expedited sunset reviews almost certain to maintain duties (FR Doc 2026-06576).

What's changing: This week's expansion of OCTG investigations to Austria, Taiwan, and UAE (FR Doc 2026-06689) represents a deliberate strategy to close every alternative sourcing corridor for OCTG. Previously, importers shifted from China to these origins — Commerce is now following the trade. Simultaneously, the continuation of prestressed concrete steel wire strand (PC strand) orders across seven countries — Brazil, India, Mexico, Korea, Thailand, Japan (FR Docs 2026-07002, 2026-07003, 2026-06998) — further restricts the steel-adjacent supply chain.

Price impact model: We estimate the aggregate impact of this week's actions on average landed cost for steel products at +8-15% over the next 12 months, broken down as:

|---|---|

Sourcing alternatives matrix:

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

Action checklist: (1) Secure domestic mill contracts for OCTG needs through Q4 2026 — deadline: before preliminary duties in August; (2) Audit all steel imports for circumvention risk, particularly any product transiting through countries not yet under investigation; (3) File interested party comments on the OCTG preliminary determinations by May 18, 2026; (4) Renegotiate construction contracts with steel escalation clauses; (5) Evaluate Saudi Arabian OCTG suppliers as the last major duty-free corridor.

Deep Dive 2: Chemicals and Industrial Inputs — PTMEG Disruption

Current duty structure: PTMEG under HS 3907.29.00 and 2932.11.00 currently enters the U.S. at MFN rates of 0-6.5% depending on the specific classification. No prior AD/CVD orders exist on PTMEG, making this a first-of-its-kind investigation for this chemical.

What's changing: The simultaneous initiation of AD investigations against all four major PTMEG export sources — China, South Korea, Taiwan, and Vietnam (FR Doc 2026-07072) — is extraordinary. This leaves only Japan (BASF/Mitsubishi), Germany (BASF), and the UK (INVISTA) as major non-investigated sources. The petitioner (likely domestic producer INVISTA) has effectively targeted the entire Asian supply chain.

Price impact model: PTMEG is a critical precursor for spandex and TPU. Current spot price is approximately $2,100-2,400/MT depending on origin.

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

Sourcing alternatives matrix:

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

Action checklist: (1) Contact Japanese and European PTMEG suppliers immediately to secure allocation before investigation-driven demand surge; (2) Review downstream product pricing to model duty pass-through; (3) Consider filing as an interested party opposing duties if you are a downstream manufacturer; (4) Evaluate backward integration or domestic PTMEG sourcing; (5) Monitor the ITC preliminary determination date of May 26, 2026.

Deep Dive 3: Consumer Goods and E-Commerce — De Minimis Shock Wave

Current duty structure: Under the now-suspended de minimis provision, shipments valued at $800 or less entered the U.S. duty-free and with minimal customs formalities. Presidential Document R1-2026-03829 continues the suspension for all countries, meaning every package regardless of value now requires formal entry.

What's changing: This is not a new action but a continuation and confirmation that the suspension is the new normal. The expansion from China-only to all countries eliminates the last workaround (shipping via third countries). Combined with the new Section 337 investigations on screen protectors (FR Doc 2026-07073) and display devices (FR Doc 2026-06580), the consumer electronics import landscape is under unprecedented pressure.

Price impact model: For a typical e-commerce seller importing $500 average-value consumer electronics:

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

Sourcing alternatives matrix: For de minimis-affected sellers, the key variable is not origin country but fulfillment model:

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

Action checklist: (1) Transition from direct-ship to U.S.-based fulfillment to consolidate entries and reduce per-unit customs costs — immediately; (2) Establish a customs broker relationship if not already in place; (3) Reclassify your top 50 SKUs for accurate duty rate assessment; (4) Model the all-in landed cost including formal entry fees ($50-150 per entry), duty, and MPF; (5) Reprice your product catalog by May 1 to reflect the new cost structure.

Strategic Analysis

The Systematic Closure of Alternative Sourcing — What Commerce's OCTG Strategy Reveals About the Next 12 Months

The development: This week's simultaneous launch of OCTG investigations against Austria, Taiwan, and UAE (FR Doc 2026-06689), combined with the expedited five-year review of OCTG orders against China (FR Doc 2026-06843), represents a deliberate, multi-front strategy by the Department of Commerce to eliminate every alternative sourcing corridor for oil country tubular goods. The Tariff Tracker Desk has tracked this pattern across multiple product categories since 2024, and the OCTG case is now the clearest example of what we call the "sourcing squeeze" playbook.

Historical parallel: The closest precedent is the steel wire rod cascade of 2014-2019. Commerce first imposed AD/CVD orders on Chinese wire rod (2014), then expanded to Belarus, Italy, Korea, South Africa, Spain, Turkey, Ukraine, and the UK (2017-2018). The result: domestic wire rod prices rose 40% in real terms between 2014 and 2019, and the domestic industry consolidated to three major producers. Import volumes fell 62% across all covered origins. The key lesson is that once Commerce starts the cascade, it rarely stops — each new investigation generates data supporting the next.

Stakeholder map: The domestic OCTG industry is led by Tenaris (through its Maverick Tube subsidiary), United States Steel Corporation, Vallourec Star, and IPSCO Tubulars. These producers, represented by the American Institute for International Steel (though AIIS has historically represented both domestic and foreign interests) and more directly by legal counsel at Wiley Rein and Kelley Drye, have the political capital and legal infrastructure to sustain multi-origin investigations. On the opposing side, oil and gas operators including the American Petroleum Institute (API) members have historically pushed back on OCTG duties, arguing they increase drilling costs. However, with U.S. oil production at record highs and domestic OCTG mills operating at 85%+ capacity utilization, the political balance has shifted toward the domestic producers.

Supply chain implications: The second-order effects are significant. (1) OCTG distributors who have diversified away from China to Austria, Taiwan, and UAE over the past five years now face a second forced migration — this time with fewer alternatives. (2) Saudi Arabia, Argentina, and Russia remain the only major OCTG producers not currently under investigation, but each carries its own risks (Saudi capacity is committed to domestic demand, Argentina faces macroeconomic instability, and Russian steel is effectively embargoed). (3) Domestic OCTG mills will gain pricing power as import alternatives narrow, potentially pushing API 5CT casing prices above $2,000/ton by Q3 2026. (4) The energy sector faces a cost-push inflation spiral: higher OCTG prices → higher drilling costs → higher breakeven prices for marginal wells → upward pressure on oil and gas prices.

Three scenarios for affected importers:

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

We assign a 55% probability to the base case based on historical patterns: when Commerce initiates investigations on alternative sources, the preliminary injury finding is affirmative approximately 80% of the time (GAO analysis of 2018-2024 AD/CVD cases). The duty rate depends on the dumping margin calculation, which for OCTG from smaller origins like Austria and UAE tends to produce moderate rates in the 15-35% range, compared to the punitive rates seen against China.

The contrarian take: What might everyone be getting wrong? The consensus view is that these investigations will significantly restrict OCTG supply and raise prices. But here's what could disrupt that narrative: domestic capacity expansion is accelerating faster than the market recognizes. Tenaris completed a $1.8 billion expansion of its Bay City, Texas mill in 2025, adding 600,000 tons of annual OCTG capacity. If demand growth in the U.S. oil patch slows (which some analysts predict due to high interest rates impacting drilling economics), we could see domestic overcapacity emerge by late 2027 — making the trade protection less impactful on pricing than the market currently expects. The smarter play may be to lock in domestic supply agreements now at today's prices, before the preliminary duties create a scramble, and renegotiate in 18 months when the capacity picture is clearer.

Compliance Deadlines Calendar

China LATAM EU APAC Trade Monitor

China

This week's Federal Register actions reinforce the structural decoupling of U.S.-China trade in industrial goods. The continuation of AD/CVD orders on kitchen appliance shelving and racks (FR Doc 2026-07107) and the preliminary results on wooden bedroom furniture with 11 companies losing separate rate status (FR Doc 2026-07114) demonstrate Commerce's tightening scrutiny of Chinese exporters' eligibility for individual duty rates. The PTMEG investigation (FR Doc 2026-07072) opens a new front in chemicals — a sector where China had been relatively less targeted than steel. The MSG sunset review continuation (FR Doc 2026-06928) for both Indonesia and China adds to the agricultural/food products under long-term AD orders. Most critically, the de minimis suspension (R1-2026-03829) specifically targets the Chinese e-commerce pipeline that had used the $800 threshold to route billions in consumer goods duty-free. As of April 13, 2026, we count 47 active AD/CVD orders on Chinese products across the Federal Register — the highest in any bilateral trade relationship in history.

Latin America

Mexico remains under the microscope. The continuation of steel rebar AD/CVD orders (FR Doc 2026-07109) means Mexican rebar exporters continue to face duty-elevated pricing in the U.S. market. This is notable in the context of USMCA: rebar qualifying for USMCA preferential treatment requires stringent origin documentation, and Commerce's circumvention enforcement on Mexican steel products has intensified since 2024. For nearshoring advocates, the message is mixed — Mexico benefits from proximity and USMCA access, but any steel or metals product transiting through Mexico faces heightened scrutiny if the raw inputs originate from China or other AD/CVD-covered countries. Brazil's exposure through PC strand sunset reviews (FR Doc 2026-07003) and the broader trend of AD orders on Brazilian steel products suggest that South American steel is increasingly contested territory in U.S. trade enforcement.

EU

European trade exposure this week centers on two key developments. The NOES sunset review (FR Doc 2026-06576) includes Germany and Sweden, two major European NOES producers. Continued AD/CVD orders on European NOES significantly impact the EU-to-U.S. EV supply chain, as European automakers manufacturing in the U.S. rely on European electrical steel for motor laminations. The OCTG investigation now includes Austria (FR Doc 2026-06689), a relatively small but strategically important OCTG source through voestalpine's Kindberg mill. This marks the first-ever U.S. AD/CVD investigation targeting Austrian steel products, signaling that Commerce is willing to pursue even traditional allies when domestic industry files petitions. The common alloy aluminum sheet final results from Turkiye (FR Doc 2026-06925), while technically a Turkiye action, has EU implications given Turkiye's close integration with European aluminum supply chains.

APAC

The Asia-Pacific region faces the broadest enforcement sweep of any week in 2026. Beyond China, the PTMEG investigations target South Korea, Taiwan, and Vietnam simultaneously (FR Doc 2026-07072) — three countries that have been the primary beneficiaries of supply chain diversification away from China. Taiwan is now under investigation in three separate actions this week: PTMEG, OCTG, and PET film (FR Doc 2026-07054). This reflects a growing pattern of trade enforcement against "China+1" destinations, challenging the narrative that moving production from China to Southeast Asia or Taiwan insulates importers from U.S. duties. The hot-rolled steel reviews for Japan (FR Doc 2026-07008) and South Korea (FR Doc 2026-07001) further tighten the net around Asian steel exporters. For importers executing Asia-Pacific sourcing strategies, the operational takeaway is clear: country diversification alone no longer provides duty insulation — product-level and supply chain-level compliance is now required.

What Were Watching Next Week

1. ITC Vote on OCTG Preliminary Injury — Week of April 20

The ITC staff report on OCTG from Austria, Taiwan, and UAE should be published in the coming weeks, with the preliminary vote scheduled before the May 18 deadline. Watch for staff briefings and pre-hearing statements that will signal whether the Commission views injury as concentrated in specific product grades. If injury is found broadly across all OCTG types, preliminary duties will apply to the full range of HS subheadings — a worst-case scenario for oil and gas importers. Prepare by: reviewing your OCTG purchase orders from these three origins and modeling the landed cost impact of duties in the 15-50% range.

2. March Trade Balance Data Release — Expected Mid-April

The Bureau of Economic Analysis is expected to release March 2026 trade balance data within the next two weeks. Given the February deficit of $57.3 billion (widening from $54.7B in January) and the acceleration in import prices, the March number could exceed $60 billion. A headline-grabbing deficit number typically triggers political pressure for additional trade enforcement, making this a leading indicator for new investigations. Prepare by: documenting your import value trends to anticipate potential political targeting of your product category.

3. Commerce Preliminary Determination — Hot-Rolled Steel from Japan

Following the preliminary results published this week (FR Doc 2026-07008) finding one of two Japanese producers sold below normal value, Commerce will issue the formal preliminary AD rates. This will trigger cash deposit requirements for Japanese hot-rolled steel imports. Given that Japan is a major steel source for automotive and manufacturing applications, the rate determination could disrupt supply agreements across the industrial sector. Prepare by: contacting your Japanese steel suppliers to understand which producer is affected and whether your contracts include duty escalation clauses.

4. De Minimis Implementation Enforcement Update — Ongoing

With the Presidential Document R1-2026-03829 now published, CBP is expected to issue updated implementation guidance for the universal de minimis suspension. Watch for port-specific directives on how CBP will handle the transition for shipments already in transit. Reports of increased holds and delays at Los Angeles, Long Beach, and JFK for e-commerce shipments have already surfaced. Prepare by: ensuring all inbound shipments have proper formal entry documentation, regardless of value.

5. PTMEG Petition Details — April-May 2026

The full text of the PTMEG petition filed with Commerce should become publicly available in the coming weeks, revealing the specific dumping margins alleged for each country. These alleged margins often serve as the ceiling for preliminary duties, making them a critical data point for cost modeling. Prepare by: monitoring Commerce's Electronic Document Filing System (ACCESS) for the PTMEG docket and subscribing to Federal Register alerts for HS 3907.29.00 and 2932.11.00.
