Three Canadian border changes taking effect between September 1 and September 8, 2026 put country of origin and product qualification at the centre of import review. For importers in Brampton, Toronto and Mississauga, the practical issue is not simply where a shipment was dispatched. The applicable treatment may depend on whether the goods qualify as UK-origin, originate in the United States, or fall within the product definition for Chinese steel racks.
What changed in September
On September 1, eligible goods from the United Kingdom, the Channel Islands and the Isle of Man became eligible for the Comprehensive and Progressive United Kingdom Tariff, or CPUKT, under tariff treatment code 35. The treatment applies subject to the relevant origin and qualification rules. The CBSA’s 2026-2 tariff schedule incorporates the applicable CPUKT rates across tariff Chapters 1 to 99. CBSA Customs Notice 26-22 describes the change.
Also on September 1, the CBSA ended the Commercial Driver Registration Program. Existing CDRP cards remain valid until expiry, while new or continuing participants are directed toward FAST. This is mainly a carrier and driver issue, but it can affect importers using the Customs Self-Assessment clearance process because those shipments rely on approved importer, carrier and driver arrangements. The CBSA announcement and its CSA information for importers provide the program details.
On September 2, provisional anti-dumping and countervailing duties became payable on subject steel racks originating in or exported from China when released from the CBSA. The applicable tariff classifications are reference points only; the authoritative product definition determines whether the goods are covered. The CBSA preliminary-determinations notice for steel racks sets out the measure.
On September 8 at 12:01 a.m., Canada began applying surtaxes of 15%, 25% or 50% of value for duty to specified U.S.-origin goods under the United States Surtax Order (2026). The covered list includes specified goods in areas such as steel and aluminum, dairy, appliances, agricultural equipment, pulp and paper, plastics and electronics. The CBSA Customs Notice 26-23 and Finance Canada’s product list identify the measure and covered products.
Why dispatch country is not enough
The U.S. surtax is based on U.S. origin, not merely the country from which the shipment was dispatched. A shipment routed through another country therefore cannot be reviewed only by looking at the final shipping point. Importers generally need to connect the tariff classification, origin determination, customs value and supplier documentation before deciding whether the surtax applies.
The UK change requires a different question. An importer should assess whether the goods qualify for CPUKT treatment and whether the available origin documentation supports the claim. A UK shipping address alone does not establish eligibility under the applicable origin and qualification rules.
The steel-rack measure adds a third distinction. The goods may be subject where they originate in or are exported from China, but the CBSA states that the product definition controls. A catalogue description or tariff classification by itself may not resolve whether a particular rack is within scope.
A practical review for GTA import teams
Separate the data fields
For affected imports, review origin, export or dispatch location, tariff classification, customs value and product description as separate fields. Combining them into a single supplier or shipment-country field can obscure the difference between a U.S.-origin surtax analysis, a UK preferential-treatment claim and a SIMA product-scope determination.
Recheck existing instructions
Importers that previously entered qualifying UK goods under another tariff treatment may want to review those entries, broker instructions and landed-cost calculations. For U.S.-origin goods, importers using CARM self-declaration generally need to calculate and enter the applicable surtax in the relevant CARM field. For steel racks, the review should identify the applicable exporter-specific or “all other exporters” rate where the goods are within scope and ensure the SIMA duties are accounted for through the customs accounting process.
Check the highway-clearance dependency
Importers using CSA should confirm that their carrier and drivers have an acceptable FAST or other approved status after the CDRP change. This is an operating-control review rather than a tariff-classification exercise, but it can affect expedited highway clearance into Ontario. It is particularly relevant to supply chains moving regularly into GTA distribution or warehousing operations.
What to put on the exception list
- U.S.-origin goods in tariff items named in the 2026 surtax product list.
- UK-origin goods that may qualify for CPUKT treatment but are still being entered under another tariff treatment.
- Steel racks from China that may fall within the authoritative product definition.
- CSA shipments relying on carriers or drivers whose program status changed after CDRP ended.
These changes do not create one universal “country of shipment” rule. They create separate checks with different evidence requirements. Importers should route each exception to the relevant classification, origin, valuation, SIMA or transportation-control review before the next accounting is prepared.
