AGRICULTURA’s October 17 comunicado states that Senasica “descartó la presencia de fiebre aftosa en un becerro inspeccionado en la estación cuarentenaria de Agua Prieta, Sonora,” with confirmation “en menos de 24 horas.” The samples “dieron positivo al virus de estomatitis papular bovina,” which the agency describes as an “enfermedad de distribución mundial y que no representa un riesgo mayor para la salud animal.” The release recalls that Mexico has been “libre de fiebre aftosa desde 1954” and says the case was handled under international protocols because the clinical signs resemble exotic vesicular diseases not present in Mexico. It gives no date for resuming exports through Agua Prieta and does not mention USDA or APHIS; for the reported October 20 restart, see the Timeline. AGRICULTURA comunicado, Oct 17 ↗

AGRICULTURA Comunicado Núm. 296 reports that a routine inspection at the Agua Prieta, Sonora quarantine station found a calf with mouth lesions (aftas). Personnel of the Comisión México-Estados Unidos para la Prevención de la Fiebre Aftosa (CPA) took samples for the Palo Alto laboratory; the station was emptied, the cattle were returned to origin and the facilities were disinfected. The release states that “la inspección de ganado que va a los Estados Unidos de América quedó suspendida en la estación cuarentenaria de Agua Prieta,” with operations to resume “la próxima semana” if an exotic disease is ruled out. Exports through the San Jerónimo, Chihuahua quarantine station “fluyen con normalidad.” The release does not mention USDA or APHIS. ICPA analysis, not stated in the source: Agua Prieta is the Mexican side of the Douglas, Arizona port that USDA reopened on August 24, and San Jerónimo serves the Santa Teresa, New Mexico port.

In the Secretaría de Economía’s official transcript (versión estenográfica) of his October 16, 2026 appearance before the Chamber of Deputies’ Comisiones Unidas de Economía, Comercio y Competitividad and de Economía Social y Fomento del Cooperativismo, Economy Secretary Marcelo Ebrard said: “estamos por determinar la cuarta ronda de conversaciones, tiene que ser antes del fin de año, con Estados Unidos.” He gave no date, location or reason for the timing. On the agreement’s term, he said the United States had announced “un periodo de 10 años con revisión anual, no es lo que más nos gusta,” adding “nos gustaría 16 años en revisión, pero está el tratado vigente.” The transcript does not mention Section 232, and agriculture appears only in an aside on the EU agreement. ICPA analysis, not stated in the source: the 10-year term with annual review is Mexican officials’ account of the U.S. position, not a published U.S. announcement or a concluded outcome; as of October 18, ICPA has located no announced date for the fourth round.

The New Mexico Department of Agriculture announced on October 15, 2026 “two additional New World screwworm cases in Grant County, one in a horse and one in a calf.” A minimum 12.4-mile-radius infested zone applies around each location, and “The northernmost zones have been combined into one larger zone, resulting in two separate infested zones in New Mexico.” Source New Mexico, via the Albuquerque Journal (October 16), reports that these are the state’s third and fourth cases, after a Lea County dog in June and a Grant County horse confirmed in mid-September (see the September 18 entry), and quotes State Veterinarian Dr. Samantha Holeck that the state is “working closely with our state and federal partners.” New Mexico Department of Agriculture, Oct 15 ↗   Albuquerque Journal (Source New Mexico), Oct 16 ↗

A Texas Animal Health Commission Executive Director order signed October 13, 2026 and effective immediately states that “the Executive Director releases the portions of Schleicher and Sutton Counties previously included within Infested Zones 06.B and 14.A from quarantine and movement restrictions.” It also releases portions of Edwards and Sutton counties within Infested Zone 04.D and “modifies and redesignates the remaining affected portions of Edwards, Sutton, and Val Verde Counties as Infested Zone 04.E,” citing “the proximity of recent NWS detections in Val Verde County within Infested Zone 19.A.” The order cites USDA sterile fly releases, “fly trapping and monitoring data” and “the absence of NWS detections during the surveillance period,” and records that on October 10 the Executive Director had already narrowed Zone 06 to 06.B. ICPA analysis, not stated in the source: the order governs movement within Texas only; it does not alter federal interstate movement or export requirements.

Oct 11, 2026

A Texas Animal Health Commission Executive Director order signed October 11, 2026 records: “On October 10, 2026, NWS was detected in a bovine in Pecos County.” The order designates areas of Pecos and Terrell counties as Infested Zone 22, effective immediately. Warm-blooded animals may not leave the zone without prior Commission authorization, inspection and treatment, and a movement permit or certificate; hides, carcasses and host-capable animal parts must be inspected and treated before removal. ICPA note: TAHC’s October 6 order, already on this tracker, released portions of Pecos County from Infested Zone 15 and redesignated the remainder as 15.A; the October 11 order does not reference it.

AGRICULTURA Comunicado Núm. 286, reporting on an animal-health forum at the Cámara de Diputados with legislators, producers and academics, says that in August “se acordó con el gobierno de los Estados Unidos la apertura gradual de la frontera a la exportación de ganado en pie desde Agua Prieta, Sonora y San Jerónimo, Chihuahua, y próximamente ocurrirá en la estación cuarentenaria de Puerto Palomas, Chihuahua.” Ayala Borunda of Senasica called the screwworm reintroduction from Central America the largest challenge to Mexican livestock since foot-and-mouth disease was eradicated more than 70 years ago, and said the pest has been contained in the south-southeast for almost 14 months with field actions and sterile fly releases. The comunicado gives no case counts or export volumes. ICPA analysis, not stated in the source: Puerto Palomas sits opposite the Columbus, New Mexico port of entry, which USDA has listed as a later port in its phased reopening.

A Secretaría de Economía aviso signed September 25 and published in the Diario Oficial de la Federación on October 7, 2026 sets the September 2026 ordinary adjustment to the maximum quota for exporting sugar to the United States for October 1, 2026 through September 30, 2027. Applying Points 13 and 15 of the October 5, 2017 Acuerdo and USDA’s September 2026 WASDE figures, the quota is the lower of the U.S.-needs calculation and CONADESUCA’s surplus estimate of 1,080,015.980 metric tons raw value (TMVC): “Xt+1 * Z= 1,077,812.641 * 0.7 ... CTt+1 = 754,468.849 TMVC.” The aviso puts the second allocation at 592,796.953 TMVC and the differential assigned with September data at 226,452.602 TMVC. The July 31 aviso had set the quota at 610,573.919 TMVC, with a first allocation of 366,344.351 TMVC. Under Punto 18, fracción II, the allocation may be exported from January 1 to September 30, 2027. ICPA analysis, not stated in the source: the quota governs Mexican export permits under the U.S.–Mexico sugar suspension agreements; it does not change what a U.S. importer files.

A Texas Animal Health Commission Executive Director order signed October 6, 2026 and effective immediately, which describes USDA as a collaborating partner in the eradication effort, modifies Infested Zone 15, established July 15, 2026 after a July 14 detection in a sheep in Pecos County: “The Executive Director further modifies Infested Zone 15 to release portions of Pecos County and redesignates the remaining affected portions of Pecos County as Infested Zone 15.A.” The order cites USDA’s detection of a fertile wild New World screwworm fly in neighboring Brewster County on September 27, 2026, which necessitated Infested Zone 13.B across portions of Brewster and Pecos counties. Warm-blooded animals may not move out of Zone 15.A without Commission inspection, treatment and a permit or certificate, and hides, carcasses and parts must be inspected and treated. ICPA analysis, not stated in the source: the order governs movement within Texas only; it does not alter federal interstate movement or export requirements. The order’s September 27 date for the Brewster County fly differs from the September 25 date in the Bloomberg report in the Timeline. Texas Animal Health Commission order, Oct 6 ↗

AGRICULTURA Comunicado Núm. 279 announces joint AGRICULTURA–SAT measures for the avocado export chain to the United States, whose packer segment the comunicado puts at US$3.5 billion. Criterio normativo 60/ISR/N, added to Anexo 7 through the Tercera Resolución de Modificaciones a la Resolución Miscelánea Fiscal 2026 (DOF, October 2, 2026), provides: “Solo será deducible del ISR la compra directa de aguacate a huertos certificados y amparada con CFDI de la productora o del productor.” The comunicado does not name the certifying authority. To make the deduction effective, packers must substantiate and retain documentation showing compliance with the phytosanitary and tax provisions. An October 1 AGRICULTURA agreement requires export fruit to come exclusively from certified orchards and separately requires the CFDI to be issued by the orchard’s owner, usufructuary or possessor; AGRICULTURA and STPS will add avocado to the Certificado Laboral para la Agroexportación. “La nueva disposición entrará en vigor el 31 de diciembre de 2026.” The comunicado does not mention APHIS or U.S. inspection. ICPA analysis, not stated in the source: the obligation falls on Mexican packers under Mexican tax law, not on U.S. importers. AGRICULTURA Comunicado Núm. 279, Oct 6 ↗

CBP’s CSMS # 70137850: “The tariff rate quota for Specialty Sugar opened on Thursday, October 1, 2026, and over-subscribed at opening moment.” For Quota Bulletin 26-310, 2027 Specialty Sugar, ACE calculated a pro rata percentage of 44.58212%, and an Entry Summary Status Notification (UC) message was generated with the prorated quantity per entry. Filers or importers have five business days from authorized release to retransmit, expiring October 13, 2026 at 4:30 p.m. local time. Questions go to HQQUOTA@cbp.dhs.gov.

Filers have five business days from authorized release to retransmit; the window expires October 13, 2026 at 4:30 p.m. local time. Questions go to HQQUOTA@cbp.dhs.gov. The message does not mention Mexico or country allocations. ICPA analysis, not stated in the source: see the October 1 entry, where CBP’s refined sugar TRQ opening marked Mexico’s line “currently excluded”; whether Mexican-origin refined sugar was prorated under Bulletin 26-319 is not established by this message.

Secretaría de Economía Comunicado No. 94 states that the prior import permit (permiso previo de importación) for sugar and food preparations, created by the Acuerdo published in the DOF on May 28, 2026, took effect on September 28, 2026, the date announced in Boletín B.SNICE 002/2026 (published August 21), for tariff fractions 1701.12.05, 1701.13.01, 1701.14.91, 1701.91.04, 1701.99.99 and 1702.90.01. For other food preparations: “Para las mercancías clasificadas en la fracción arancelaria 2106.90.99, se prorroga hasta el 02 de noviembre del 2026.” During the transition those goods may be imported by declaring the applicable exception identifier; afterwards they are subject to the permit rules where that applies according to their composition and characteristics. Requirements, procedure and documentation for the permit can be consulted on the SNICE portal and in the Ventanilla Digital Mexicana de Comercio Exterior; the comunicado notes the related trámite was to be made available in VUCEM. The comunicado does not state whether U.S.-origin goods are exempt. ICPA analysis, not stated in the source: members exporting sugar or sugar-containing preparations to Mexico should confirm with their Mexican customs broker whether the permit applies to their shipments before November 2.

FDA’s October 2, 2026 update reports that CDC has declared the outbreak over and that FDA has closed its investigation. Final counts are 488 illnesses in 34 states and 65 hospitalizations, with no deaths; the last illness onset was August 26, 2026. FDA: “A common grower in Sinaloa, Mexico, that supplies to Coast Citrus Distributors, was identified as the likely source in this outbreak.” Coast Citrus Distributors recalled on August 5, followed by downstream recalls from Taylor Fresh Foods (August 9), Whole Foods Market (August 12) and NatureBest (August 14). FDA visited a common Mexican distributor identified through traceback; no jalapeños were available for sampling, all environmental samples were negative for Salmonella, and “FDA was unable to determine a route or source of contamination.” ICPA analysis, not stated in the source: the FDA update is silent on import alerts and other import actions; it neither announces nor rules one out.

FDA’s October 2 update states that FDA has concluded its investigation of the multistate Cyclospora outbreak linked to shredded iceberg lettuce, which CDC declared over on September 11 (see above). Final counts are 12,883 illnesses in 21 states, 570 hospitalizations and two deaths. FDA: “Of the samples collected during the onsite inspections in Mexico, two samples tested positive for Cyclospora”: one from a tank holding outgoing wastewater at the Taylor Farms de Mexico processing facility and one from a drainage ditch at an iceberg lettuce grower identified through traceback. FDA states the positive samples “add to the strong epidemiological data and traceback convergence supporting the link between this outbreak and recalled shredded iceberg lettuce from Taylor Farms de Mexico.” ICPA analysis, not stated in the source: the FDA update is silent on import alerts and other import actions; it neither announces nor rules one out.

CBP Quota Bulletin 26-301-2027, posted September 23, opens the 2027 refined and specialty sugar TRQ at 12:00 p.m. ET on October 1, 2026, with entry summaries accepted from midnight local port time until noon ET, and says the quota is “expected to oversubscribe at Opening Moment.” Restraint levels are 7,090,000 kg for refined and specialty sugar (no CQE, HTSUS 9903.17.01 prefix), 10,300,000 kg for Canada (CQE required) and “Mexico (CQE required) 2,954,000 kg (currently excluded).” CBP annotates the Mexico line “(currently excluded)” without further explanation. Companion Quota Bulletin 26-304 opens the 2027 sugar-containing products TRQ the same day at 59,250,000 kg for Canada, with the 8-digit Canadian export certificate number in box 33 of CBP Form 7501, and 5,459,000 kg for other countries except Mexico. For the sugar-containing products quota (QB 26-304), entries submitted after 12:01 a.m. and before 8:30 a.m. local port time on opening day receive an entry time of 08:30 for quota purposes; the refined sugar quota (QB 26-301) instead opens at noon ET as above. ICPA analysis, not stated in the source: Mexican sugar enters under the U.S.–Mexico suspension agreements rather than this TRQ (see the September 23 entry). CBP Quota Bulletin 26-301, Sep 23 ↗

CBP’s CSMS # 70050970, sent September 28, gives filing guidance for Proclamations 11061, 11062 and 11063 (Canadian alcoholic beverages, dairy and motor-vehicle-sector products; the dairy proclamation is 11062, 91 FR 58319). CBP: “As of 12:01 a.m. Eastern Time on September 29, 2026, any entry containing covered products will be unconditionally rejected by U.S. Customs and Border Protection (CBP).” Covered goods fall under HTSUS headings 0404, 1702, 1703, 2202 through 2208 and 8711, with product-level scope in the attached annexes. Rejections carry ACE error codes 239 (FTZ e214), 335 (cargo release) and 886 (entry summary). Goods imported before the effective time remain subject to the existing 50 percent Section 338 duty under Proclamations 11046 through 11048, and covered goods imported before 12:01 a.m. ET on September 29 that were entered into a bonded warehouse or admitted to a Foreign Trade Zone before that time may be withdrawn at the 50 percent duty. The message does not mention USMCA and sets out no exception for USMCA-qualifying goods. Questions go to TradeRemedy@cbp.dhs.gov. ICPA analysis, not stated in the source: by the same logic CBP applies to alcoholic beverages, dairy-list goods that fall outside the dairy annex should remain enterable at the 50 percent Section 338 duty under Proclamation 11047; confirm against ANNEX-I-DAIRY.pdf.

APHIS proposed rule (Docket APHIS-2023-0069, 91 FR 60521): “Current APHIS regulations specify that live birds and other avian commodities may not be exposed to highly pathogenic avian influenza (HPAI) or sourced from premises quarantined for HPAI within the 90 days immediately preceding export to the United States. We are proposing to reduce this timeframe to 28 days preceding export to the United States.” APHIS ties the change to international standards (WOAH reduced its minimum recovery period from 90 to 28 days) and says it “would allow foreign regions to resume the export of live birds and other avian commodities to the United States sooner following an outbreak of HPAI.” APHIS notes it already adopted the 28-day period for Canada on a provisional basis in 2022, pending this rulemaking. This is a proposed rule; APHIS “will consider all comments that we receive on or before November 23, 2026.” ICPA analysis, not stated in the source: the proposal would codify Canada’s existing provisional treatment and extend the same window to Mexico and other trading partners; import requirements do not change until a final rule is published.

USTR published a notice allocating the remaining quantity of the fiscal year 2027 WTO raw cane sugar tariff-rate quota (91 FR 60487). The in-quota quantity is 1,117,195 MTRV, the U.S. WTO minimum, of which 1,061,202 MTRV was allocated in the July notice (91 FR 46822; see July 23 above). “The U.S. Trade Representative is allocating the remaining quantity of 55,993 MTRV to the following countries in the amounts specified below.” The largest shares go to the Dominican Republic (11,931 MTRV) and the Philippines (9,151 MTRV). The allocations are applicable as of September 23, 2026, for the quota year running October 1, 2026 through September 30, 2027.

The New Mexico Department of Agriculture reports that “New Mexico animal health officials have confirmed the state’s second case of New World screwworm,” detected September 17 in a horse in Grant County near Mimbres; the state’s first case was in Lea County. A minimum 12.4-mile-radius infested zone applies: animals in the zone must be inspected and, if necessary, treated before moving within or out of it, while routine movement is generally not restricted unless an inspector identifies a higher-risk situation. The department has expanded surveillance and fly trapping.

CDC: “This outbreak has ended. The number of recent infections linked to the outbreak has significantly declined.” Final counts are 12,883 illnesses in 21 states, 570 hospitalizations and two deaths. FDA’s September 11 update states that “FDA’s onsite inspections and sample collection at iceberg lettuce growers and the processing facility in Mexico, in coordination with Mexican officials, have ended” and that FDA “will continue to work with federal, state, and international partners to complete its investigation.” ICPA analysis, not stated in the source: neither agency’s September 11 update announces an import restriction or import alert tied to the closure.

CBP’s CSMS # 69851916 implements Proclamations 11064 and 11065 for goods entered for consumption or withdrawn from warehouse on or after 12:01 a.m. ET September 15, 2026. The attached list “provides the complete list of HTSUS classifications subject to Section 338 duties as of September 15, 2026, including 122 additional HTSUS classifications now subject to HTSUS 9903.03.12 or HTSUS 9903.03.14.” Ten classifications come off: 2208.30.60 and 2208.70.00 from 9903.03.12, and 2501.00.00 (salt), 2523.29.00 (Portland cement), 2940.00.60, 4803.00.40, 4818.90.00, 7801.10.00, 8537.10.91 and 9507.10.00 from 9903.03.14; the 9903.03.13 dairy list is unchanged. CBP states: “As of September 15, 2026, only goods subject to HTSUS 9903.03.13 are eligible to claim HTSUS 9903.03.15.” The additional duties remain eligible for drawback, and the Chapter 98 and FTZ privileged-foreign-status rules are restated. ICPA analysis, not stated in the source: importers of Canadian-origin goods should re-run the attached “Section 338 Canada Modified HTS LIST eff 091526” against their Chapter 99 filing logic, because coverage changed in both directions, and CBP’s August 21 guidance (CSMS # 69606660) sets out no USMCA exception, and the White House fact sheet states the duties apply “regardless of whether a good originates under the U.S.-Mexico-Canada Agreement (USMCA).” “The additional duties imposed by headings 9903.03.12 to 9903.03.14 are eligible for drawback.” CBP CSMS # 69851916, Sep 11 ↗

Proclamation 11062 (91 FR 58319, published September 14) excludes the products in its Annex from importation “effective with respect to goods imported on or after 12:01 a.m. eastern time on September 29, 2026,” stating that on August 21 Canada “reneged on its commitment, ceased negotiating in good faith, and did not remove the discrimination or unreasonable and unequal imposition at issue in Proclamation 11047.” Annex I lists whey protein concentrates and modified, fluid and dried whey (HTSUS 0404.10.05, .08, .11, .15, .20, .48, .50 and .90), invert, cane and other molasses (1702.90.35, 1703.10.30, 1703.10.50, 1703.90.30, 1703.90.50) and non-alcoholic beer (2202.91.00). Covered goods imported but not entered for consumption or withdrawn from warehouse before September 29 remain subject to the 50 percent Section 338 duty rather than the ban. The White House fact sheet, issued the same day Canada’s counter-tariffs took effect (which it describes as “new retaliatory tariffs on about $20 billion of U.S. exports, including steel, dairy, and agricultural equipment”), records the five proclamations: import bans on certain Canadian alcohol and dairy products previously subject to the 50 percent tariffs under Proclamations 11046 and 11047, and scope modifications effective September 15 that remove rock salt and cement and add products “ranging from all-terrain vehicles (ATVs) to additional dairy products.” It states: “These Section 338 tariffs apply to all covered goods regardless of whether a good originates under the U.S.-Mexico-Canada Agreement (USMCA).” ICPA analysis, not stated in the source: CBP’s September 11 implementing list (below) leaves the 9903.03.13 dairy heading unchanged and adds no dairy-specific subheadings, so members with dairy lines should check the attached list rather than the fact sheet’s summary for what actually moved on September 15.

In a companion Federal Register notice, the Foreign Agricultural Service announced the transfer of amounts for certain dairy articles from the historical license category (Appendix 1) to the lottery, or nonhistorical, license category (Appendix 2) under the Dairy Tariff-Rate Quota Import Licensing regulation for the 2027 quota year. The adjustment changes which quantities are available through historical rather than lottery licenses and bears directly on any member planning 2027 dairy TRQ license applications.

The Foreign Agricultural Service published a Federal Register notice assessing a fee of $325 for each dairy import license issued for the 2027 tariff-rate quota year, under 7 CFR 6.33. The fee applies to every person or firm licensed by USDA to import dairy articles subject to tariff-rate quotas under the Harmonized Tariff Schedule. Members holding or applying for 2027 dairy TRQ licenses should budget the fee into their applications. Dairy TRQ administration remains a live friction point in the U.S.–Canada track of the joint review. Federal Register, Sep 2 ↗

The Department of Finance Canada published its countermeasures package and the operative tariff-item product list. Verified at the tariff-item level, the order applies 50 percent to heading 0402 milk and cream, including concentrated, sweetened and powdered forms, and to heading 0404 whey and milk and whey protein products, both within and over access commitment; and 25 percent to heading 0406 cheese and curd. Dairy and agricultural equipment are named among the targeted sectors. The list runs to 629 tariff items and was updated as of August 26, 2026. Scope turns on eligibility to be marked as a good of the United States under the CUSMA marking regulations, and goods in transit when the measures come into force are excluded. Effective 12:01 a.m., September 8, 2026.

USDA APHIS reopened the Douglas, Arizona port of entry to cattle imports from Mexico on August 24, 2026, the first port to reopen under the phased plan announced July 24. Imports move under a science-based inspection and treatment protocol jointly agreed by the United States and Mexico, which importers of Mexican cattle must follow. APHIS states that later openings at Santa Teresa and Columbus, New Mexico will proceed conditionally on Mexico’s progress against Action Plan milestones, and that openings may be paused if post-opening audits identify increased risk in Sonora or Chihuahua.

The President issued a proclamation temporarily suspending the additional duties of up to 50 percent imposed under Proclamations 11046, 11047, and 11048 of July 20, 2026 on Canadian alcoholic beverages, dairy products, and motor vehicles. The suspension moved the effective date from 12:01 a.m. ET on August 19 to 12:01 a.m. ET on August 22, 2026, citing Canada’s expressed commitment to remove the discriminations at issue and the status of negotiations, and provided for refunds of any duties already collected. Negotiations then collapsed, and the duties, covering roughly 52 Canadian dairy tariff classifications, entered into force as rescheduled on August 22. White House proclamation, Aug 18 ↗

Agriculture Secretary Brooke Rollins visited the livestock inspection facilities at the Douglas, Arizona port of entry on July 29 and announced a $25 million USDA commitment for a new sterile fly dispersal facility in Arizona to strengthen the long-term New World screwworm response. The facility will join existing sterile fly operations in Texas, Mexico, and Panama; site selection in the Douglas area is underway with the Arizona Department of Agriculture. Rollins also outlined preparedness measures ahead of the port’s planned August 24 reopening to Mexican cattle under the phased plan USDA announced July 24. USDA press release, Jul 29 ↗

FDA and CDC expanded the outbreak to nine states, reporting 1,947 laboratory-confirmed infections, at least 98 hospitalizations, and no deaths, with illness onset dates from June 22 to July 20, 2026. Taylor Farms de Mexico removed all iceberg lettuce sourced from central Mexico from the U.S. market on July 17 and initiated a recall covering retail and food-service distribution. FDA increased border screening. A product sample initially reported positive was subsequently identified as a false positive; the recall rests on traceback and epidemiological data rather than a positive product test. Taylor Farms has voluntarily suspended all production at its central Mexico facility pending an independent food-safety review, and reports no confirmed positive product samples as of July 24, 2026. These figures are superseded by FDA’s August 5, 2026 update; see SPS, Biotechnology & Compliance.

USDA will open the Douglas, AZ port of entry to cattle trade beginning August 24, 2026, contingent on Mexico’s adherence to the joint action plan on New World screwworm, while beginning operational steps toward later openings at Santa Teresa and Columbus, NM. Every animal will undergo full USDA inspection, and cattle must originate from approved low-risk areas of Sonora or Chihuahua. USDA retains discretion to pause openings if risk increases. Southbound movement is separately constrained: Mexico has suspended imports of several U.S. live-animal categories following screwworm detections in the United States.

USTR set the FY 2027 raw cane sugar in-quota quantity at 1,117,195 MTRV, allocating 1,061,202 MTRV by country and reserving 55,993 MTRV for allocation before October 1, 2026. Canada receives 10,300 MTRV and Mexico 2,954 MTRV of the 22,000 MTRV refined sugar TRQ, both unchanged from FY 2026. Allocations to net sugar importers are conditioned on verification of origin. This is WTO quota administration, not a USMCA action, but it fixes documentation and entry-timing requirements for the quota year opening October 1, 2026.

Three presidential proclamations impose an additional 50 percent duty on listed Canadian goods covering dairy, alcoholic beverages, and motor vehicles, effective 12:01 a.m. ET on August 19, 2026. The duties apply regardless of whether a good originates under USMCA. Energy, potash, goods already subject to Section 232 duties, and certain other categories are excluded. The dairy proclamation grounds the action in Canada’s cheese tariff-rate quota eligibility criteria under USMCA compared with its treatment of EU cheese under CETA. The motor vehicle proclamation is covered on the Automotive page.

A Chapter 31 panel found Mexico had not conducted a qualifying risk assessment and that its 2023 decree restricting genetically engineered corn was more trade restrictive than necessary, in violation of multiple SPS obligations. Mexico’s Secretaría de Economía issued an acuerdo dated February 4, 2025, in compliance with the panel ruling, that leaves without effect Articles Sixth (section II), Seventh and Eighth of the 2023 decree. ICPA has not located a U.S. assessment of full compliance. Acuerdo ↗ See Disputes & Panel Decisions.

A Chapter 31 panel found that Article 3.A.2.6(a) did not prohibit Canada from limiting TRQ applicants to processors, distributors, and further processors, and rejected the claim that Canada’s market-share allocation system violated Article 3.A.2.11(b). Canada’s current dairy TRQ administration reflects this outcome; no further Chapter 31 proceeding on the issue has been located as of July 26, 2026. See Disputes & Panel Decisions.

Mexico’s genetically engineered corn measures

A Chapter 31 panel ruled on December 20, 2024 that Mexico’s February 2023 decree restricting genetically engineered corn was inconsistent with multiple SPS obligations, including risk-assessment and necessity requirements.

Mexico’s February 2025 acuerdo, issued in compliance with the panel ruling, leaves the challenged provisions of the 2023 decree without effect; a U.S. assessment of full compliance has not been located. Mexico has continued to emphasize native-corn protection and food sovereignty even after the adverse ruling.

With the Section 338 50 percent duties on listed Canadian dairy, alcohol, and motor vehicle goods set to take effect August 19 regardless of USMCA origin, Canadian Press reporting describes intensified negotiations in Washington: Trade Minister Dominic LeBlanc met with industry groups and senators, while chief trade negotiator Janice Charette remained in Washington over the weekend for detailed discussions. Prime Minister Carney said his government remains loyal to the supply management system, while separate Canadian Press reporting says some work is being done around the dairy TRQ quotas negotiated in 2018. Ottawa has not announced retaliation targets and has said it will not retaliate before the tariffs take effect. BNN Bloomberg / Canadian Press, Aug 7 ↗

In an official statement, Prime Minister Carney announced the suspension of Canada–U.S. trade talks, saying last-minute changes in the U.S. proposed terms were unfair, uneconomic, and called into question the reliability of any deal. The statement notes the United States planned to impose a 50 percent tariff on approximately $28 billion in Canadian goods at midnight, and commits Canada to matching those tariffs dollar for dollar alongside support measures for affected workers and businesses. The Section 338 duties, including the dairy list, entered into force at 12:01 a.m. ET on August 22, 2026. This supersedes the August 7 posture above: Ottawa has now announced retaliation. Prime Minister of Canada, Aug 21 ↗

Publicly supported the July 20 Section 338 dairy action, arguing that Canada’s administration of its USMCA dairy tariff-rate quotas has produced persistent underfill and denied the market access the agreement contemplated. Both organizations have also pressed USTR to address Canadian dairy protein export practices and protection of common food names through the review. Statement dated July 20, 2026.

Welcomed the conclusion of the Mexico City round and urged the parties to move from bilateral management toward a trilateral resolution. NCGA has consistently identified Mexico as the largest purchaser of U.S. corn and Canada as the largest ethanol market, and has emphasized the value of USMCA dispute settlement for biotechnology access. Statement dated July 24, 2026.

Dairy Farmers of Canada publicly urged the federal government not to offer additional concessions on dairy or supply management in the talks with Washington ahead of the August 19 tariff effective date, stating that “our food sovereignty is not for sale; a bad deal is not worth the cost” and arguing that prior Canadian compromises were met with fresh U.S. demands. The statement sharpens the industry-position contrast with U.S. dairy groups such as NMPF, which has backed USTR’s use of Section 338 against Canada’s TRQ administration. Statement reported August 7, 2026. BNN Bloomberg, Aug 7 ↗

Minister Dominic LeBlanc met USTR Jamieson Greer in Washington on August 13, their fourth meeting in three weeks, with negotiations described as ongoing ahead of the August 19 effective date for the 50% Section 338 tariffs covering Canadian dairy. Reporting indicates the U.S. tabled a revised proposal on August 11 that would lower some tariffs by less than Ottawa sought, and that further Canadian concessions on dairy access may be required. Dairy Farmers of Canada restated its opposition to any further supply-management concessions.
