CBSA notices do not all have the same operational effect. Some introduce a new surtax or tariff treatment. Others revise an administrative process, consolidate existing guidance or clarify how an existing rule applies. For importers, the distinction affects whether a commercial accounting change is required, whether a classification or origin review is appropriate, or whether no immediate entry change is needed.
The 2026 notices reviewed below illustrate that difference. The most immediate entry-level change is the surtax on specified U.S.-origin goods. By contrast, the tariff-rate-quota bonded-warehouse notice expressly says it is a clarification, not a policy change. D-Memorandum revisions may still matter significantly, but often because they change the framework or evidence expected during verification rather than creating a new duty rate.
Start with the legal effect, not the publication date
When a notice arrives, an importer’s first question should be: does this change the treatment of the goods, change the process for accounting, or explain an existing process? The answer determines the next control to review.
| Type of notice | Operational question | Example from the 2026 notices |
|---|---|---|
| New customs treatment | Does the entry require a different duty, surtax or tariff treatment? | Specified U.S.-origin goods became subject to surtaxes effective September 8, 2026. |
| Tariff treatment made available | Does the importer qualify for a preferential rate, and can origin be supported? | Eligible U.K.-origin goods became eligible for CPUKT treatment effective September 1, 2026. |
| Administrative or system revision | Do records, forms or accounting terminology need to be updated? | D11-6-8 was revised for CARM Release 3 and CAD accounting. |
| Clarification | Was an existing rule explained without changing policy? | The TRQ bonded-warehouse notice confirmed the process for final release. |
This classification is a practical reading tool, not a substitute for reviewing the full notice. The specific source should control when the notice contains conditions, exceptions or transitional provisions.
Changes that can affect the commercial accounting declaration
U.S.-origin surtaxes
Canada began applying surtaxes of 15%, 25% or 50% to specified goods originating in the United States effective September 8, 2026. The measure can apply where covered goods are shipped through a third country, and the notice also addresses goods eligible for courier or postal remission, remission, duties relief and drawback programs. The applicable treatment depends on the goods and the facts of the importation, so origin and tariff classification should be reviewed together rather than treated as separate checks.
The CBSA notice identifies Commercial Accounting Declaration codes 26186A, 26186B and 26186C for the applicable surtax rates. Importers whose products may fall within the covered goods should discuss the classification, origin evidence and code selection with their broker before relying on a previous accounting setup. The source is Customs Notice 26-23.
United Kingdom tariff treatment
Eligible goods from the United Kingdom, the Channel Islands and the Isle of Man became eligible for Comprehensive and Progressive United Kingdom Tariff treatment effective September 1, 2026. The related tariff update became available in all formats on September 16, 2026. Importers considering the treatment should validate both the tariff classification and the origin qualification before claiming a preferential rate. The relevant source is Customs Notice 26-22.
This is different from a general rate reduction for all U.K. shipments. The benefit depends on the goods meeting the applicable conditions. A broker discussion should therefore include the supplier’s origin information, the tariff item and the date of importation.
Tariff-description revision for electric motorcycles and cycles
The description for tariff item 8507.60.20 changed effective August 6, 2026, from “electrically-powered motorcycles” to “motorcycles or cycles with an electric motor.” Importers with potentially affected goods should review prior classifications and product descriptions with their broker. The change is described in Customs Notice 26-21.
Changes that primarily affect verification and evidence
D11-6-8 and CARM terminology
D-Memorandum D11-6-8 was revised on September 9, 2026, to reflect CARM Release 3, including the replacement of Forms B3-3 and B2 with the Commercial Accounting Declaration. The memorandum concerns CBSA verification of origin, tariff classification and value for duty for goods not covered by a free trade agreement. It addresses verification records, questionnaires, correction procedures and supporting documentation. The revision is available in D11-6-8.
For an importer, the practical issue is record alignment. Internal files may still refer to older forms or workflows even though the current accounting terminology is CAD-based. A review should test whether entry references, commercial invoices, valuation support, classification rationale and origin records can be connected to the accounting declaration used in CARM.
Automotive parts and materials
CBSA consolidated former D-Memoranda D10-15-15 and D10-15-21 into one memorandum covering tariff items 9958.00.00 and 9959.00.00. The guidance applies to importers of automotive parts, accessories and materials claiming duty-free treatment for original-equipment manufacturing or eligible aftermarket applications. The memorandum states that importers should be able to substantiate actual end use, with examples including a verifiable part-number audit trail. See D10-15-15.
For automotive supply chains serving facilities in Brampton, Mississauga or Toronto, the useful control is not simply retaining a supplier invoice. Importers should discuss how part numbers, purchase records and end-use information are connected across the customs file and production or distribution records.
Clarifications and administrative revisions are still worth reading
TRQ goods entering a bonded warehouse
Customs Notice 26-20, published August 21, 2026, clarified the process for tariff-rate-quota goods entering a customs bonded warehouse and expressly stated that it was not a policy change. To obtain the within-access rate at final release, the goods must have a valid shipment-specific Global Affairs Canada import permit covering the date the goods exit the warehouse. The permit may be received after warehouse entry if it covers the final-release date. The details are in Customs Notice 26-20.
The distinction matters for warehouse planning. An importer should not treat the notice as a new warehouse-entry requirement, but should confirm that the permit position can support the intended final-release date. That discussion may involve the importer, broker, warehouse operator and the party responsible for obtaining the permit.
Sufferance-warehouse enrolment
D-Memorandum D4-1-4 was updated July 6, 2026, to include Customs Sufferance Warehouse Enrolment Form BSF897. The memorandum states that CBSA aims to decide complete licence applications within 60 business days after receipt through the CARM Client Portal. Applicants and operators should use the current memorandum and form when reviewing a warehouse licensing file. See D4-1-4.
This is primarily relevant to warehouse operators and applicants, rather than every importer releasing goods from a warehouse. It can nevertheless affect parties planning air-cargo or highway logistics around the GTA, including freight moving through Pearson and Peel Region facilities.
A practical review sequence for importers and brokers
- Identify the affected population. Start with tariff items, country of origin, end use, transport channel or licence status. Do not apply a national notice to every shipment automatically.
- Separate entry changes from evidence changes. A new surtax or preferential tariff treatment may affect the CAD. A D-Memorandum revision may instead require stronger or differently organised supporting records.
- Confirm the effective date. Distinguish the date goods became subject to a measure from the date a revised document was published or made available.
- Test exceptions and programmes. For example, the U.S.-origin surtax notice addresses remission, duties relief, drawback and courier or postal treatment. The TRQ clarification turns on the permit covering the final-release date.
- Assign an owner. Classification, origin, valuation, warehouse operations and accounting may sit with different teams. The broker conversation should identify who supplies each supporting record and who approves any correction.
For importers moving goods through Toronto-area air or highway networks, the best outcome is not a blanket rework of every customs file. It is a documented decision about which notices affect the company’s products, entries, programmes or facilities, and which notices only clarify an existing process.
Questions to take to your broker
- Does any product in the current tariff database match the U.S.-origin surtax notice, and is the origin evidence sufficient for the proposed treatment?
- Are any U.K. imports being considered for CPUKT treatment, and has origin been confirmed before the preferential rate is claimed?
- Do product descriptions or classifications need review for electric motorcycles or cycles?
- Can the company’s verification file be followed from commercial documents to the CAD and the underlying origin, classification and value-for-duty analysis?
- For automotive parts using tariff items 9958.00.00 or 9959.00.00, can actual end use and part-number history be substantiated?
- For TRQ goods in a bonded warehouse, who will obtain and track the shipment-specific permit against the final-release date?
The central discipline is to match the response to the notice’s actual effect. A new duty or surtax calls for entry controls. A tariff preference calls for eligibility and origin review. A D-Memorandum revision calls for an evidence and terminology check. A clarification calls for confirming that the existing process is being applied to the right event.
