Recent CBSA notices and D-Memorandum revisions do not create one uniform task for every Canadian importer. The practical question is which import files, accounting records and operating procedures each change touches. Between July 29 and October 27, 2026, CBSA published measures affecting U.S.-origin goods, qualifying U.K. goods, wood cabinets and vanities, lithium-ion battery classifications, tariff-rate-quota goods in bonded warehouses, CARM verification, vehicle imports and vehicle-part relief. Importers in Toronto, Mississauga and Brampton should sort these developments by shipment profile rather than treating every notice as a general customs-system change.
Start with the shipment profile, not the publication type
The table below identifies the first file or workflow that generally deserves review. The dates are the effective or revision dates stated in the applicable CBSA notice or memorandum.
| Shipment or business profile | Change to review | Date | First discussion with your broker |
|---|---|---|---|
| Listed U.S.-origin goods | 15%, 25% or 50% surtax and new CARM accounting codes | September 8, 2026 | Origin, tariff item, surtax code and in-transit treatment |
| Qualifying goods from the U.K., Channel Islands or Isle of Man | CPUKT preferential tariff treatment | September 1, 2026 | Origin qualification and proof of origin |
| Covered wood cabinets, vanities or subassemblies | 25% safeguard surtax based on value for duty | July 31, 2026 | Tariff classification, exclusions and provisional-measure treatment |
| TRQ goods released from a bonded warehouse | Shipment-specific permit requirement for the within-access rate | August 21, 2026 clarification | Permit date, Type 10 amendment and ex-warehouse accounting |
| Commercial importer subject to verification | D11-6-8 revised for CARM and CAD records | September 9, 2026 | Origin, classification, value-for-duty and adjustment records |
| Vehicle or vehicle-part importer | D19-12-1 and D10-15-15 revisions | September 2 and August 14, 2026 | SWI authorization data, end use and relief claims |
This is a triage tool, not a replacement for checking the text of the relevant notice. A shipment may fall into more than one row. For example, a U.S.-origin product could require both an origin review and a surtax review, while goods entering a bonded warehouse may require a separate check before the goods leave that warehouse.
Files that may change the amount payable
U.S.-origin goods: confirm origin before looking at the shipping route
Effective September 8, 2026, Canada imposed surtaxes of 15%, 25% or 50% on specified goods originating in the United States. CBSA states that importers report the applicable surtax in the CARM Commercial Accounting Declaration using codes 26186A, 26186B or 26186C. The notice also addresses in-transit goods, Chapter 98 and Chapter 99 goods, CUSMA-related relief and goods imported through the Courier Low Value Shipment program. CBSA updated the notice on October 23, 2026. See Customs Notice 26-23.
The relevant fact is origin, not simply the country from which the shipment departs. The measure can apply when U.S.-origin goods are shipped to Canada from another country. Importers using Pearson air-cargo facilities or GTA distribution operations should therefore have the origin analysis available before the CAD is prepared, rather than relying only on the routing or the export location.
Discuss with your broker whether the affected tariff items in your catalogue are mapped to the correct surtax code, whether any CUSMA or Chapter 98/99 treatment is relevant, and how in-transit or courier shipments should be handled.
Wood cabinets and vanities: separate the safeguard review from ordinary duty classification
Effective July 31, 2026, certain wood cabinets, vanities and subassemblies became subject to a 25% safeguard surtax based on value for duty. The CBSA notice sets out the tariff classifications, exceptions and accounting instructions. The provisional measure may apply for up to 200 days beginning July 31, 2026, pending the Canadian International Trade Tribunal process. See Customs Notice 26-17.
Importers should not treat this as only a rate-table exercise. The review should connect the product description, tariff classification, country or territory of origin, value for duty and any applicable exception. This is particularly relevant for distributors, builders, kitchen suppliers and home-improvement businesses receiving inventory into Peel Region warehouses or other Ontario distribution facilities.
Qualifying U.K. goods: shipment from the U.K. is not enough
Effective September 1, 2026, the United Kingdom, the Channel Islands and the Isle of Man were added to the Customs Tariff for Comprehensive and Progressive United Kingdom Tariff treatment. Eligible goods may receive the applicable preferential tariff treatment under the U.K. accession arrangements. CBSA states that importers must meet the applicable origin and proof-of-origin requirements; shipment from the U.K. alone does not automatically establish entitlement. The T2026-2 tariff files were released on September 16, 2026. See Customs Notice 26-22.
For an importer, the useful file check is whether the supplier can support the applicable origin requirement and whether that proof is retained with the entry records. A broker can also review whether the preferential tariff treatment was claimed consistently after September 1 and whether any prior entries need attention.
Files where the main risk is release, verification or post-release evidence
Bonded-warehouse TRQ goods: check the exit event
On August 21, 2026, CBSA clarified how tariff-rate-quota goods entering customs bonded warehouses are treated when the importer later seeks the within-access rate. CBSA states that the goods must ultimately have a valid, shipment-specific Global Affairs Canada import permit covering the date the goods leave the warehouse. Where goods entered under a General Import Permit, the importer must first amend the Type 10 CAD before using a Type 20 or 21 ex-warehouse movement at the within-access rate. CBSA expressly describes this as a clarification of existing policy, not a policy change. See Customs Notice 26-20.
The operational checkpoint is therefore the warehouse exit, not just the original warehouse entry. Importers, brokers and warehouse operators handling food, agricultural or steel-related TRQ goods should compare the permit, the shipment and the planned ex-warehouse accounting before the goods move into the importer’s distribution network.
CARM verification files: replace legacy-form assumptions with CAD records
CBSA revised D11-6-8 on September 9, 2026, to reflect CARM Release 3 and the replacement of the B3-3 Canada Customs Coding Form and B2 adjustment form with the Commercial Accounting Declaration. The memorandum covers CBSA verifications of non-free-trade-agreement origin, tariff classification and value for duty. See D11-6-8, Verification of Origin, Tariff Classification, and Value for Duty.
Commercial importers subject to verification should discuss how their accounting, correction and post-release-adjustment files identify the CAD and preserve the supporting origin, classification and valuation evidence. This applies regardless of the port used, including businesses whose records are managed from Toronto, Mississauga or Brampton while entries move through different Canadian locations.
Vehicles and vehicle parts: review two different memoranda
CBSA revised D19-12-1 on September 2, 2026. The revision includes a definition of temporary residents and confirms electronic processes for vehicle entries through the Single Window Initiative, including authorization data for case-by-case vehicle imports and electronic reporting through the Registrar of Imported Vehicles. For certain case-by-case imports, the process letter no longer needs to be presented, but the importer still needs the Transport Canada authorization number in advance and must provide it through the SWI IID process. See D19-12-1, Importation of Vehicles.
Separately, CBSA consolidated D10-15-15 and D10-15-21 into D10-15-15 on August 14, 2026. The consolidated memorandum covers tariff items 9958.00.00 and 9959.00.00, which provide duty-relief treatment for certain parts, accessories and materials used in manufacturing specified vehicles. It also clarifies documentation and end-use expectations. See D10-15-15, Tariff Items 9958.00.00 and 9959.00.00.
Vehicle importers should keep the two reviews separate: one concerns the electronic vehicle-entry process and authorization data; the other concerns eligibility, documentation and end use for vehicle-part relief.
Changes that are narrower but still worth screening
CBSA amended the description of tariff item 8507.60.20 effective August 6, 2026. The wording referring to “electrically-powered motorcycles” was replaced with wording covering “motorcycles or cycles with an electric motor.” CBSA describes this as a tariff-description clarification rather than a newly announced duty rate. Importers of lithium-ion batteries, electric motorcycles, e-bikes and related battery products should compare their classifications with the amended description. See Customs Notice 26-21.
Authorized Courier Low Value Shipment participants also received a separate change effective September 14, 2026: they may use third-party air carriers that are not PIP-certified if those carriers remain bonded and shipments are presented at the designated sufferance warehouse. This is primarily an operator issue, but importers using the program may wish to confirm that their courier’s process remains aligned. See Customs Notice 26-24.
What to put on the broker-review agenda
- Identify products by origin, tariff item and shipment route, with special attention to listed U.S.-origin goods and qualifying U.K. goods.
- Separate a new duty or surtax review from a clarification or record-format review.
- For bonded-warehouse TRQ goods, verify the permit against the date of withdrawal and planned ex-warehouse CAD.
- For CARM verification readiness, locate the CAD, origin support, classification rationale, value-for-duty records and any adjustment history.
- For vehicles and vehicle parts, confirm whether the issue is SWI authorization data, RIV reporting, end-use evidence or tariff-item relief.
- Ask the broker whether any entries made after the stated effective or revision date require correction, documentation follow-up or no action.
The safest review method is shipment-profile based: begin with the goods and the procedure actually used, then apply the notice or memorandum that governs that fact pattern. That approach reduces the risk of treating a warehouse clarification as a new tariff, or treating a CARM record change as if it altered the underlying origin or classification rule.
