U.S. AD/CVD Orders on Chinese Van Trailers
On October 6, 2026, Wabash reported trade actions affecting the North American trailer market. Following the U.S. Department of Commerce's final dumping findings on August 26, 2026, the U.S. International Trade Commission (ITC) issued a final affirmative injury determination on September 25, 2026, covering van-type trailers and subassemblies imported from China, including trailers assembled in Canada using Chinese subassemblies.
Commerce is issuing final AD/CVD orders on Chinese trailers and subassemblies. Trailers assembled in Canada using Chinese subassemblies are classified as Chinese products and subject to Chinese duties.
For Canada and Mexico, Commerce issued preliminary affirmative antidumping determinations alongside a preliminary countervailing duty determination for Mexico, requiring importers to post cash deposits. Final Commerce determinations for Canada and Mexico are scheduled for December 17, 2026, with final ITC votes set for early 2027.
Additionally, Section 232 tariffs of 25% apply to the full declared value of imported trailers as derivative steel and aluminum products effective since April 6, 2026.
CBP Evasion Findings on Mobile Access Equipment
U.S. Customs and Border Protection (CBP) issued a final affirmative determination of duty evasion against importer XCMG North America Corporation on October 6, 2026, following an investigation prompted by allegations from the Coalition of American Manufacturers of Mobile Access Equipment (CAMMAE).
CBP found that XCMG evaded antidumping and countervailing duty orders on mobile access equipment, including boom lifts, scissor lifts, and telehandlers, from China by falsely asserting that imports were manufactured at its facility in Mexico and undervaluing entries.
CBP suspended XCMG's entries retroactively to July 2025 and established combined duty rates of 69.31% on suspended and future entries from Mexico. The determination confirmed that mobile access equipment originating in China was fraudulently claimed as manufactured in Mexico to evade U.S. antidumping and countervailing duty orders.
Mexican Customs and Trade Administration
Customs Law Reform Tightens Rules on Undervaluation
On October 6, 2026, the Plenary of the Chamber of Deputies approved in general and in particular the reform to the Customs Law submitted by President Claudia Sheinbaum, with 334 votes in favor and 119 against in general, and 338 in favor and 114 against in particular. The reform amends articles 144, 151, 153, 154 and 177.
It empowers customs authorities to carry out precautionary embargos even when declared undervaluation is below 50 percent, and to initiate verification powers of their own motion when the declared value is lower than the transaction price of identical or similar goods.
If undervaluation exceeds 20 percent, the importer may request substitution of the precautionary embargo through a cash deposit or a customs account for the contributive difference within 10 business days following notification. The opinion was referred to the Senate of the Republic for review.
On October 7, 2026 it was clarified that the amendment eliminates the previous 50 percent threshold to proceed with precautionary embargo and reduces from 50 percent to 20 percent the difference between declared value and reference value needed to presume an infringement. If undervaluation is below 20 percent, the importer may substitute the embargo with a deposit in a customs guarantee account; if it exceeds 20 percent, only with a cash deposit for the amount of omitted contributions.
The Confederation of Associations of Customs Brokers of the Mexican Republic (CAAAREM) confirmed its support for the reform promoted by President Claudia Sheinbaum Pardo and announced that its 804 affiliated customs brokers will reinforce, together with importers and in coordination with ANAM, SHCP and SAT, pre-clearance due diligence through a reinforced file documenting the commercial relationship with the supplier, its existence, location, capacity and representation, the price of the goods, sale conditions, payment traceability and customs value when there is no sale or payment.
Annex 4 Repeal Ends Automatic Import Permits for Textiles
The Ministry of Economy (SE) and the National Customs Agency of Mexico (ANAM) issued Joint Communiqué 93/2026 on October 5, 2026, providing guidance on the Resolution that repeals Annex 4 of the Estimated Prices Resolution by SHCP, published in the Official Gazette of the Federation on September 14, 2026 and effective since September 15, 2026.
The repeal eliminates the enforceability assumption of the automatic import permit for textile and apparel products provided for in Annex 2.2.1, numeral 8 BIS, fraction II of the Foreign Trade Rules Agreement. As of September 15, 2026, that automatic import permit, conditioned on unit prices lower than the estimated price, ceased to be required.
The agencies specified that elimination of the automatic permit does not modify or reduce the tariffs applicable to textile products. Operations previously initiated through consolidated customs declarations will continue to be governed by article 56 of the Customs Law.
On October 6, 2026, SE and ANAM detailed the scope for operations through weekly or monthly consolidated pedimentos under articles 37 and 37-A of the Customs Law. If the first shipment entered before the repeal took effect, that date applies for regulatory compliance of the entire consolidated declaration, and the exchange rate at the close of the operation must be declared. The measure benefits commercial flows of inputs and garments from origins such as China and the United States.
MVE Electronic Value Declaration Deadline Extended with Phased Rollout
The Tax Administration Service (SAT), in coordination with the National Customs Agency of Mexico (ANAM) and the Digital Transformation and Telecommunications Agency (ATDT), announced the extension of the deadline to submit the Electronic Value Manifestation (MVE) until October 31, 2026.
Following SAT's publication on September 30, 2026 of the First Advance Version of the Third Resolution of Amendments to the General Foreign Trade Rules (RGCE) for 2026 and Annex 22, the three agencies issued a joint press release on October 2, 2026 confirming the extension. The measure establishes gradual incorporation of electronic transmission of the customs value file through the Single Window for Foreign Trade Procedures (VUTCE), in accordance with rule 1.5.1 of the General Rules of Foreign Trade.
Starting November 1, 2026, MVE transmission through VUTCE will be implemented gradually by customs regime: manufacturing, transformation or repair in a fiscalized precinct on November 1, 2026; strategic fiscalized precinct on November 15, 2026; transit of goods on December 1, 2026; fiscal deposit on December 15, 2026; temporary import on January 1, 2027; and definitive import on January 15, 2027.
The need to transmit attachments with the MVE such as transport documents, certificates of origin or guarantees in customs account is exempted when they are already incorporated into the pedimento. Companies with IMMEX programs and OEA certification must validate their specific operations by customs regime, since the IMMEX program does not automatically exempt from all documentary obligations of the MVE. Law firm reports from Pérez-Llorca on October 6, 2026 and Holland & Knight on October 7, 2026 confirmed the identical timeline and details.
2027 Budget Proposal Cuts UPCI Funding by 39 Percent
On October 7, 2026 it was announced that the Federal Expenditure Budget Project for 2027 proposes a 39 percent reduction in the budget of the Unit of International Trade Practices (UPCI) of the Ministry of Economy, assigning 62 million pesos compared with the 102 million pesos approved in 2026. Of that amount, 55 million pesos will go to salaries and operating expenses.
As of July 31, 2026, UPCI maintained 69 active procedures and investigations on dumping and subsidies, of which 40 percent correspond to products originating in China, including investigations on bicycles and steel.
Specialists warned that this budgetary adjustment runs counter to commitments under Chapter 10 of T-MEC and weakens Mexico's operational capacity against unfair trade. There were 97 countervailing duties in force on 63 products from 22 countries, 46 percent of them from China. UPCI maintains 59 investigations in progress and 10 preliminary resolutions, of which 40 percent correspond to Chinese products such as bicycles, steel, self-adhesive paper tapes, acrylic sheet, screws, mirror glass, tableware, metal zippers, hydraulic jacks and pipes.
USMCA Review Launch
USTR Opens Public Consultation for 2027 USMCA Joint Review
The Office of the U.S. Trade Representative (USTR) launched a public consultation process on October 5, 2026, ahead of the 2027 USMCA joint review. The public comment deadline is January 12, 2027.
This follows the U.S. decision earlier this year declining to confirm agreement continuation. That decision leads to annual joint reviews until unanimous extension or agreement termination on July 1, 2036.
USTR requested public comments on USMCA operation, implementation, compliance issues, specific recommendations for USTR proposals, factors affecting the North American investment climate, USMCA effectiveness in promoting investments that strengthen U.S. competitiveness, productivity, and technological leadership, and strategies for North American economic security and cooperation on non-market policies and practices of third countries. The announcement was published in the Federal Register on October 5, 2026.
Concurrently, bilateral trade negotiations between the U.S. and Mexico were delayed to October 2026. Mexican trade negotiators are seeking tariff relief from Washington on steel and aluminum, currently facing 50% tariff rates, and automobiles, facing 25% penalties.
On October 6, 2026, the president of the Confederación de Cámaras Industriales (Concamin), Alejandro Malagón, estimated that the fourth round of bilateral trade negotiations between Mexico and the United States could be delayed until after the United States midterm elections. Trade dialogue continues actively through two channels with the USTR and the United States Department of Commerce. Among the main pending issues are the tariffs applied under Section 232 to steel and aluminum, as well as discussions on their derivative products and the automotive sector.
On October 7, 2026, USTR initiated the next stage of the USMCA joint review by opening a public comment period following the Federal Register notice.

Tariffs of up to 60% on Chinese inputs raise autoparts production costs in Mexico
On October 7, 2026, René Mendoza, president of the Value Chain for Industry in Mexico (CAPIM), and Gabriel Padilla, general director of the National Autoparts Industry (INA), stated that tariffs of up to 60% imposed by Mexico on imports of inputs from Asia, mainly from China, are raising the cost of autoparts production in the country.
Mendoza explained that these inputs previously paid about 3% in import duties. The jump to rates of up to 60% is forcing purchasing teams to seek substitute suppliers within Mexico.
Padilla added that, amid the T-MEC review and rising purchase orders, the industry must evaluate how much value, technology and productive capacity can be integrated competitively in Mexico and North America.
Maersk updates North America ocean capacity and customs requirements for October 2026
On October 7, 2026, Maersk published its North America market update for October 2026. The carrier reported tight ocean freight capacity on transatlantic and transpacific trade lanes, with restricted spot availability.
Maersk highlighted stronger customs compliance enforcement in North America. U.S. Customs and Border Protection (CBP) has been voiding importer identification numbers that lack complete identity information since September 18, 2026. Mexican borders are also applying stricter enforcement of Mexican Official Standards (NOMs).
The carrier introduced its Trade and Tariff Studio to help importers with customs compliance. It also announced that its Gulf Ocean Express ocean service will add a weekly port call at Freeport, Texas, starting October 21, 2026.
Rules and countervailing duties on steel and aluminum imports from China into Mexico
In Mexico, imports of steel and aluminum require automatic steel import notices processed in VUCEM and registration in the Padrón de Sectores Específicos.
Definitive countervailing duties remain in force for hot-rolled steels originating from China and Vietnam, and for hollow aluminum profiles originating from China and the United States.
These countervailing duties apply according to the country of origin of the input, regardless of whether the materials enter temporarily under IMMEX programs or through intermediary countries.

Expert Outlook
Core judgment
Mexico’s customs enforcement is structurally tightening around undervaluation and NOM compliance, compressing the compliance buffer for China-origin FCL imports just as carriers lock in Asia–Mexico GRIs and Chinese input tariffs already elevate landed costs. The Chamber’s cut of the precautionary-embargo threshold from 50 % to 20 % plus next-day NOM activation for selected lines mark a durable shift toward higher verification intensity rather than episodic checks.
Drivers decoded
Hard facts establish the shift: the Chamber of Deputies approved Customs Law amendments to articles 144, 151, 153, 154 and 177 that allow precautionary embargos below the former 50 % undervaluation threshold and presume infringement at a 20 % difference; the opinion now sits with the Senate. Hapag-Lloyd and CMA CGM simultaneously announced US$1,000 GRIs from Far East/Asia to Mexico coasts effective 15 October 2026. Autoparts associations CAPIM and INA report that Mexican tariffs of up to 60 % on Asian—mainly Chinese—inputs (previously ~3 %) are already raising production costs and forcing purchasing teams to seek Mexican substitutes. SE’s Annex 2.4.1 update made plumbing and AC-motor NOM provisions effective 29 September 2026—one day after publication—while Maersk’s October update confirms restricted transpacific spot availability and stricter NOM enforcement at Mexican borders. SAT/ANAM extended the MVE deadline to 31 October 2026 before phased VUTCE rollout begins 1 November 2026.
Soft signals reinforce durability: CAAAREM’s endorsement of reinforced pre-clearance due diligence and the unusually short NOM notice interval indicate an enforcement-first posture rather than temporary tightening.
Mexican customs and regulatory agencies (ANAM/SAT/Chamber) pursue higher tax collection and political signalling of customs integrity; their leverage lies in threshold cuts, ex-officio verification and release tempo, under a mindset willing to accept short-term friction for longer-term compliance gains. Ocean carriers (Hapag-Lloyd, CMA CGM, Maersk) defend yield and utilization on the Asia–Mexico lane while major East–West routes soften; they leverage GRI announcements and spot rationing with an opportunistic pricing mindset on secondary trades where capacity remains constrained. Mexican mid- and large-scale importers of Chinese FCL cargo seek predictable landed costs and clearance times; their leverage is volume switching and North American supplier diversification, yet their mindset shows heightened sensitivity to tariff jumps and verification risk, already prompting searches for Mexican substitutes.
Chain effects
The Chamber of Deputies’ cut of the undervaluation precautionary-embargo threshold from 50 % to 20 %, with the measure now before the Senate, raises the probability of embargos and cash-deposit requirements on China-origin FCL. Importers therefore face longer clearance times and working-capital lock-up, which in turn intensifies pressure for more rigorous supplier-price documentation.
Hapag-Lloyd and CMA CGM’s announced US$1,000 GRI per dry container (and NOR for Hapag-Lloyd) from Asia to Mexico coasts, effective 15 October 2026, lifts the ocean-freight component of landed cost immediately. Purchasing teams must reassess China-sourced volumes against the backdrop of already elevated input tariffs of up to 60 %.
NOM provisions for plumbing goods (NOM-012) and small AC motors (NOM-033) took effect one day after publication on 29 September 2026, producing sudden border-check intensification on the covered tariff lines. Non-compliant China-origin containers risk detention or rejection, creating short-term continuity risk for affected FCL flows.
Ocean carriers stand as the clear beneficiaries: the US$1,000 GRIs capture higher yields on the Latin America lane while major East–West routes soften and capacity remains tight.
Scenarios and signposts
Key watchpoints that remain open are the Senate vote and final wording on the Customs Law undervaluation threshold (20 % versus any upward revision) within the next 7–21 days; the actual implementation rate of the Hapag-Lloyd/CMA CGM US$1,000 GRI on Asia–Mexico sailings after 15 October 2026; the incidence of precautionary embargos or cash-deposit demands at Manzanillo and Lázaro Cárdenas on China-origin FCL once the reform is published; NOM detention or rejection statistics for plumbing and small-motor tariff lines in the first two weeks of October; and MVE transmission readiness plus any further SAT/ANAM clarifications before the 1 November phased start. Confirmed facts include the MVE deadline extension to 31 October 2026 and the VUTCE phased rollout culminating in definitive import on 15 January 2027, as well as the NOM plumbing and motor provisions already effective since 29 September 2026.
Baseline (highly likely): Senate clears the Customs reform with the 20 % threshold intact; GRIs largely stick; NOM and MVE rollouts proceed on schedule. Landed costs for China-origin FCL rise via freight plus residual duty and compliance friction; clearance times lengthen modestly on value-sensitive cargo. Trigger: Senate review completes without major dilution of the 20 % threshold and carriers implement the announced GRIs.
Optimistic (may): Senate softens or delays the embargo threshold cut and/or carriers partially roll back GRIs amid softer demand. Compliance pressure eases slightly and freight uplift is muted, limiting further deterioration in China–Mexico FCL cost and time predictability. Trigger: Senate amends the 20 % threshold upward or postpones entry into force; spot rates soften before 15 October.
Pessimistic (may): Reform enters force promptly, NOM detentions spike on newly covered lines, and GRIs hold fully while Chinese input tariffs continue to bite. Clearance delays and cash-deposit requirements compound, pushing China-origin FCL costs and dwell times higher for Mexican importers. Trigger: Rapid Senate passage plus visible increase in precautionary embargos and NOM holds at Mexican ports.
