Recent Canadian tariff changes do not create one universal entry problem. They create several different tests for the same shipment: whether the goods qualify for preferential origin, whether the tariff item is current, and whether a new surtax applies to the correct value for duty. Importers in Mississauga, Brampton and Toronto should review those fields together rather than treating every change as a simple tariff-code update.
What changed between June and September 2026
The updates cover preferential tariff treatment, tariff descriptions, steel quota administration and new surtaxes. The effective dates are not aligned, so an importer’s review should begin with the accounting date and the measure applicable on that date.
| Measure | Effective date | Primary review |
|---|---|---|
| CCCT shipping and origin guidance | June 4, 2026 | Route and supporting origin documents |
| GPT and LDCT origin and direct-shipment guidance | June 25, 2026 | Origin percentage and transshipment records |
| Steel tariff-rate-quota amendments | June 28, 2026, effectively | Quota period, tariff item and permit controls |
| Canada–Indonesia CEPA framework | July 1, 2026 | Origin, preference and transshipment evidence |
| Canned-vegetable safeguard surtax | June 19, 2026 | Product scope, origin and value for duty |
| Wood-cabinet and vanity safeguard surtax | July 31, 2026 | Scope, safeguard code and accounting field |
| Tariff description for item 8507.60.20 | August 6, 2026 | Classification and ruling review |
| UK CPTPP tariff treatment | September 1, 2026 | UK origin, treatment code and certification |
| U.S.-origin counter-surtaxes | September 8, 2026 | U.S. origin, listed goods and value for duty |
Sources for these measures include the CBSA memoranda, customs notices and Canada Gazette instruments linked below. The dates above should be matched to the specific goods and accounting circumstances before an entry is finalized.
The three-field review: origin, classification and value
1. Origin determines whether preference or a surtax can apply
Origin is not always the same as the country from which a shipment departs. For GPT and LDCT claims, the revised CBSA guidance addresses origin and direct-shipment requirements and states that at least 60% of the ex-factory price must originate in GPT beneficiary countries or Canada. Where goods move through an intermediate country, documentation concerning transshipment and customs control can be relevant to the claim. CBSA Memorandum D11-4-4
The revised CCCT guidance similarly addresses shipping requirements and supporting documentation, including Form A or an exporter’s statement of origin. Importers claiming CCCT treatment generally need to be able to support the route and show that goods transiting non-beneficiary countries remained under customs control. CBSA Memorandum D11-4-5
The Canada–Indonesia Comprehensive Economic Partnership Agreement became applicable on July 1, 2026. Eligible goods must satisfy the agreement’s origin rules, and goods transshipped through another country may retain preferential treatment where the applicable customs-control and route documents can be produced.

The UK’s CPTPP tariff treatment took effect on September 1, 2026. Importers of qualifying UK-origin goods generally need to update tariff-treatment codes and origin-certification processes; preference remains conditional on the applicable CPTPP origin rules. CBSA Customs Notice 26-22
For U.S.-origin goods covered by the United States Surtax Order (2026), origin is determined using CUSMA-country marking rules. Goods exported to Canada through a third country can still be covered if they originate in the United States. CBSA Customs Notice 26-23
2. Classification determines which measure is in scope
The steel amendment changed quarterly tariff-rate-quota periods and quantities, revised the tariff classifications covered by particular quota items and moved certain tariff items between quota categories. Steel service centres, fabricators, distributors and manufacturers should therefore compare the current tariff-item mapping with their quota and permit procedures, rather than relying on an older product list.

The tariff description for item 8507.60.20 changed on August 6, 2026, from a reference to “electrically-powered motorcycles” to “motorcycles or cycles with an electric motor.” Importers of lithium-ion accumulators or batteries and related electric motorcycles or cycles should review existing classification rulings and consider whether validation is appropriate. CBSA Customs Notice 26-21
Product scope also matters for the two provisional safeguard measures. The canned-vegetable order covers specified canned corn, peas, beans, mixed vegetables, chickpeas and related products. The wood measure covers specified wood cabinets, vanities and subassemblies, including certain kitchen, bathroom and closet installations; it can apply to assembled, unassembled or flat-packed goods and goods containing non-wood components.

3. Value for duty is the base for several new charges
No new standalone Canadian customs valuation method or valuation regulation was identified in this period. The valuation impact comes from measures calculated on the existing value-for-duty base, under the existing valuation framework. CBSA customs valuation guidance
The provisional canned-vegetable safeguard surtax is 10% of value for duty and applies from June 19, 2026, for up to 200 days, subject to the Canadian International Trade Tribunal inquiry. The order includes listed country and goods exceptions, so origin and product scope still need to be checked before applying the rate. Canada Gazette: canned-vegetable safeguard surtax
The provisional wood-cabinet and vanity safeguard surtax is 25% of value for duty and took effect July 31, 2026. CBSA specifies safeguard code 26169A and requires the amount to be reported in CAD field 87 rather than the ordinary surtax field 85. CBSA Customs Notice 26-17
The U.S.-origin measures impose surtaxes of 15%, 25% or 50% on specified goods from September 8, 2026. The rates are calculated on the existing value for duty under sections 47–55 of the Customs Act. CBSA also notes that Canadian customs brokerage charges included in the price paid or payable may be deductible associated costs where the statutory conditions are met. The applicable codes are 26186A, 26186B and 26186C. CBSA Customs Notice 26-23
What GTA importers should put in the review queue
Food, retail and consumer products
Importers distributing canned vegetables through Mississauga, Brampton or Toronto warehouses should match each product description and tariff item against the safeguard order, then confirm origin and the value-for-duty calculation. A supplier invoice showing the shipping country is not, by itself, the complete review record where the measure turns on origin.
Steel, machinery and industrial inputs
Steel importers should reconcile tariff-item mappings, quota periods and permit-control procedures after the June amendment. Businesses sourcing machinery or other products from the United Kingdom should separately verify UK origin and the applicable CPUKT treatment. These are different checks: a UK shipment does not automatically establish eligibility for preferential treatment. CBSA Customs Notice 26-22 Canada Gazette: steel surtax order amendment
U.S.-origin goods moving through a third country
For listed U.S.-origin goods, the review should identify the actual origin under the applicable marking rules, not just the export location. Importers should discuss with their broker what proof of origin is available, whether an exception applies, which surtax code is relevant and whether the value-for-duty calculation includes potentially deductible associated costs. CBSA Customs Notice 26-23
Questions to resolve before the next entry
- Which measure was in force on the shipment’s accounting date?
- Does the product satisfy the exact tariff-item and product-description scope?
- Is the claimed origin supported by the required statement, certificate or other records?
- If the goods transited another country, can the route and customs control be documented?
- Is the charge based on value for duty, and has that base been reviewed under the existing valuation rules?
- Does the accounting require a special safeguard or surtax code or a particular CAD field?
- Does an existing classification ruling remain consistent with the amended tariff description?
The practical objective is a synchronized entry file: current classification, supported origin and a defensible value-for-duty calculation. Importers should provide those records to their broker before accounting and discuss any preference claim, exemption, quota treatment, surtax code or valuation adjustment that depends on facts not visible on the commercial invoice.
