Away from the tariff dispute with the United States, the first week of September delivered a new tariff treatment for goods from the United Kingdom, an extension of the federal fuel excise suspension, the second-period quota for electric vehicles from China, a tariff item description change, and a cluster of consultation and reporting deadlines that close this month.
UK accession to CPTPP: tariff treatment code 35 from September 1
The Comprehensive and Progressive Agreement for Trans-Pacific Partnership entered into force for the United Kingdom on September 1, 2026. Customs Notice 26-22 announces the corresponding amendment to the Departmental Consolidation of the Customs Tariff (T2026-2): the United Kingdom, the Channel Islands and the Isle of Man are added to the list of CPTPP-eligible countries under a new tariff treatment, the Comprehensive and Progressive United Kingdom Tariff (CPUKT), code 35, with the applicable rates reflected across Chapters 1 to 99.
Practical impact: importers of UK goods now have two preferential options, the Canada–UK Trade Continuity Agreement and CPTPP, each with its own rules of origin and its own certification. Where a good does not qualify under one agreement it may under the other, and the staging of duty rates differs, so the treatment claimed should be chosen line by line rather than by default.

Federal fuel excise tax suspension extended to January 31, 2027
Customs Notice 26-11 was updated on September 3 to reflect the extension of the temporary suspension of the federal excise tax on unleaded gasoline, unleaded aviation gasoline, diesel, aviation fuel and leaded aviation gasoline. The suspension now runs to January 31, 2027; from February 1 to March 31, 2027 the tax applies at 50% of the regular rates, and the full rates resume on April 1, 2027. Importers continue to enter excise exemption code F00 on the Commercial Accounting Declaration during the suspension.

Electric vehicles from China: 24,500-unit allocation for September to February
Global Affairs Canada’s Notice to Importers No. 1168, dated August 29, sets out the second quota period for electric vehicles from China. Imports require a shipment-specific import permit; eligible vehicles within the quota enter at the 6.1% MFN rate. The allocation for the period September 1, 2026 to February 28, 2027 is 24,500 vehicles, plus any unused volume from the prior period. The quota is open to original equipment manufacturers resident in Canada, or Canadian agents of non-resident manufacturers, who may apply up to 30 days before shipment. Electric tricycles and non-passenger vehicles such as golf carts and mobility scooters are outside the notice.

Tariff item 8507.60.20 renamed
Customs Notice 26-21 records that, effective August 6, 2026 under Tariff Amendment T2026-1, the description of tariff item 8507.60.20 changes from “electrically-powered motorcycles” to “motorcycles or cycles with an electric motor.” Holders of advance rulings that touch this item should check whether the ruling is affected and request validation if it is.

CARM applied the wrong exchange rate on two dates
CARM Bulletin 5423 reports that, because of a discrepancy between the exchange-rate source system and CARM, some Commercial Accounting Declarations with a direct shipment date of December 20, 2025, and certain rates for July 21, 2026, were calculated with an inaccurate exchange rate. New declarations now pull the correct rates. For declarations already processed, the CBSA says it will proactively re-trigger the affected CADs to apply the updated rates, and any adjustment an importer files on an affected CAD will recalculate with the correct rate automatically.
Practical impact: importers with shipments on either date should expect revised duty and tax amounts to appear on those transactions without filing anything, and should reconcile their statements of account once the re-trigger runs.
Deadlines this month
- September 14: consultations close on a potential Canada–Türkiye free trade agreement. Global Affairs Canada is seeking views on goods for tariff removal or phase-in, import sensitivities, non-tariff and technical barriers, services, environment and labour. Submissions go to TCE-consultations@international.gc.ca. Consultation details
- September 29: Federal Plastics Registry Phase 1 reporting of 2025 calendar-year data is due. Phase 1 covers producers of plastic packaging, electrical and electronic equipment, and single-use or disposable plastic products, including importers, brand owners and marketplace facilitators that place them on the Canadian market; producers below 1,000 kg a year are exempt. Reports cover product category, resin type and source, quantity in kilograms and the calculation method. The delay announced for Phases 2 and 3 does not affect this deadline.
