2026 CBSA Notices: Build the Evidence File Before the CAD Is Reviewed

The 2026 CBSA notices are easier to manage as an evidence problem than as a calendar of effective dates. A GTA importer may have to support a U.S.-origin surtax position, a safeguard exclusion, a tariff classification, a bonded-warehouse withdrawal or an automotive end-use claim, and each position depends on different records. The practical question is not only whether the Commercial Accounting Declaration (CAD) was submitted correctly. It is whether the importer can demonstrate why the accounting was correct.

Start with the position being claimed

Recent notices affect separate customs positions. They should not be handled through one generic “customs documents” folder. Importers in Toronto, Mississauga and Brampton may want to identify the claim involved in each product or transaction and then retain the evidence that supports that claim.

• Origin and surtax: specified U.S.-origin goods became subject to surtaxes of 15%, 25% or 50% effective September 8, 2026. The measure can apply to commercial and casual imports, including goods entering Canada from a third country when the goods originate in the United States. The CBSA notice also identifies self-assessment in the CAD and origin documentation as relevant controls. Read Customs Notice 26-23.
• Safeguard treatment: specified wood cabinets, vanities and subassemblies became subject to a provisional 25% safeguard surtax effective July 31, 2026. The notice covers certain assembled, unassembled, flat-pack and ready-to-assemble goods, while also identifying exclusions and origin-based exceptions. Read Customs Notice 26-17.
• Preferential tariff treatment: eligible U.K.-origin goods became eligible for the Comprehensive and Progressive United Kingdom Tariff treatment effective September 1, 2026, subject to applicable CPTPP origin and other requirements. Read Customs Notice 26-22.
• Classification: the description for tariff item 8507.60.20 changed on August 6, 2026, from “electrically-powered motorcycles” to “motorcycles or cycles with an electric motor.” Importers with an advance ruling were told to review whether the changed description affects that ruling. Read Customs Notice 26-21.

Organize records by the customs question

Can the origin position be proved?

For products potentially covered by the U.S. surtax, the relevant file should connect the imported product to its origin. A commercial invoice alone may not answer every origin question. Importers should discuss with their broker which supplier origin statements, manufacturing records, bills of materials, purchase documents or other records are appropriate for the goods and the applicable measure.

The same discipline applies to a claim for U.K. preferential treatment. The importer should be able to connect the tariff treatment to the goods’ origin and to the applicable CPTPP requirements. A change in supplier, production location or product configuration can affect the support for a preferential claim, so origin evidence should be reviewed when sourcing changes rather than only when CBSA asks for it.

Does the product description match the tariff position?

The electric motorcycle and cycle amendment illustrates why product catalogues and classification files should be compared with the Customs Tariff wording. Importers should preserve the specifications used for classification, including product descriptions, technical data and the version of the ruling or tariff analysis relied on.

For cabinets, vanities and subassemblies, the product file should make clear whether the goods are within the described product scope and whether an exclusion or origin-based exception is being claimed. The notice states that the safeguard amount is entered in the CAD “Safeguard” field using safeguard code 26169A, rather than the ordinary “Surtax” field. The filing treatment is set out in Customs Notice 26-17.

Warehouse and end-use claims need transaction-level support

TRQ goods leaving a bonded warehouse

CBSA’s August 21, 2026 notice clarified, rather than changed, the procedure for tariff-rate-quota goods entered into a customs bonded warehouse. To receive the within-access tariff rate when goods leave the warehouse, the importer needs a valid, shipment-specific Global Affairs Canada import permit covering the date of exit. Read Customs Notice 26-20.

This is particularly relevant to GTA importers using bonded warehousing and distribution facilities in or around Mississauga, Brampton and Toronto. The evidence file should link the warehouse entry, the specific goods, the date of withdrawal and the shipment-specific permit. Where goods entered under a General Import Permit, the notice describes circumstances in which the importer may initially account for the applicable over-access treatment and later submit a CAD adjustment after obtaining the shipment-specific permit. A Type 20 or 21 ex-warehouse transaction cannot claim within-access treatment unless the Type 10 accounting has first been amended where required. The procedural details are in Customs Notice 26-20.

Automotive parts and manufacturing materials

CBSA revised D10-15-15 on August 14, 2026, consolidating guidance previously found in D10-15-15 and D10-15-21 for tariff items 9958.00.00 and 9959.00.00. The guidance concerns duty-free treatment for qualifying vehicle parts, accessories and materials used in manufacturing. Importers claiming tariff item 9958.00.00 should be prepared to substantiate actual end use. CBSA identifies evidence such as verifiable part-number audit trails, contracts and letters of understanding. Read D10-15-15.

Ontario automotive manufacturers, parts suppliers and contract manufacturers should therefore reconcile the part number on the entry with the internal purchasing and production records. The issue is not simply whether a product is commonly described as an automotive part; the file should support the claimed tariff item and the actual use represented to CBSA.

Make the CAD record traceable to the underlying file

CBSA revised D11-6-8 on September 9, 2026, to reflect CARM Release 3 and replace references to the former B3-3 and B2 forms with the CAD. The memorandum addresses verification of non-free-trade-agreement origin, tariff classification and value for duty. It describes CBSA use of questionnaires, letters, verification visits, CAD data, product information and other records when reviewing those positions. Read D11-6-8.

Importers should discuss with their broker whether their records can move cleanly from the CAD to the commercial invoice, packing information, classification analysis, origin support and value-for-duty calculation. This is a control design issue: the person reviewing a CAD should be able to identify the source record without reconstructing the shipment from disconnected email threads.

Vehicle businesses should also review the revised D19-12-1, dated September 2, 2026. The memorandum updated the definition of temporary residents and continues to distinguish commercial vehicle imports from personal imports. Businesses importing vehicles for their own commercial, industrial, occupational or institutional use are described as reporting the entry at a CBSA office, including through SWI/IID or release service option 911. Read D19-12-1.

What to discuss with your broker

1. Which products in your catalogue are potentially affected by the U.S. surtax, cabinet safeguard, U.K. preferential treatment or electric-cycle description change?
2. What source record supports origin, classification, value for duty, exclusion or end use for each affected product?
3. For bonded-warehouse withdrawals, does the permit identify the shipment and cover the date of exit?
4. Can your ERP, warehouse and accounting records be linked to the CAD and any later adjustment?
5. Do advance rulings, supplier statements, product descriptions or automotive end-use records need review after the 2026 revisions?

The notices do not create one universal evidence standard for every importer. They do make product scope, origin, permit status, end use and CAD traceability important review points. A focused file-by-file check is more useful than simply downloading every notice and storing it without connecting the notice to an entry process.
