Anti-dumping and countervailing duties no longer apply to new releases of certain photovoltaic modules and laminates originating in or exported from China. The Canadian International Trade Tribunal rescinded the relevant order effective September 17, 2026, and the Canada Border Services Agency updated its notice on September 22. For importers, the immediate task is not a broad tariff review: it is confirming whether past and future shipments fall within the rescinded product definition and identifying eligible duties for refund.
What changed on September 17
The rescission covers certain Chinese photovoltaic modules and laminates subject to the order. For covered goods released on or after September 17, anti-dumping and countervailing duties no longer apply. The products are normally classified under tariff items 8541.42.00.00 and 8541.43.00.00, but classification alone does not decide whether a shipment is covered. The product definition in the notice controls.
The change is relevant to Canadian importers bringing these goods into distribution, installation or resale channels. That can include businesses operating in Brampton, Toronto and Mississauga, but the rule is national rather than GTA-specific. The CBSA notice is the controlling source for the covered goods, effective date and refund treatment.

The refund window runs back to March 25
The end of duties on new releases is only one part of the change. CBSA says it will automatically refund eligible anti-dumping and countervailing duties paid on covered goods released on or after March 25, 2026. Goods released before March 25 are not eligible for refunds arising from this rescission.
CBSA also says outstanding reassessments for eligible releases after March 25 will be terminated. Importers therefore have two separate dates to keep distinct:
- March 25, 2026: the beginning of the stated refund-eligibility period for covered releases.
- September 17, 2026: the effective date from which the duties no longer apply to new releases.
Those dates should not be collapsed into a single “effective date” field in an internal import file. A shipment released before September 17 may still be relevant to the refund review, while a shipment released before March 25 falls outside the stated refund window.
Why the product definition matters more than the tariff item
The notice identifies tariff items 8541.42.00.00 and 8541.43.00.00 as the normal classifications for the products, while also stating that the product definition controls. This means an importer reviewing entries should not treat a tariff-code search as a complete scope test.
A practical review can begin with the commercial and technical records already associated with the shipment. Importers who are assessing whether a release is covered may wish to compare the product description and supporting specifications against the notice’s product definition, then retain the basis for that conclusion with the entry record. Where a shipment contains modules or laminates with differing specifications, the review may need to be performed at the product level rather than by assuming that every line under a tariff item has the same treatment.
Records to assemble for the review
- Release dates for affected entries.
- Tariff items used for the photovoltaic goods.
- Product descriptions and technical information used to identify the goods.
- Amounts of anti-dumping and countervailing duties paid on releases from March 25, 2026 onward.
- Any outstanding reassessment connected with an eligible post-March 25 release.
This is a control and reconciliation checklist, not a substitute for determining whether a particular product meets the legal definition in the notice.
What importers should do with open and future entries
Importers with shipments released after September 17 may want to check whether duty amounts were calculated under the rescinded order. If a broker entry, internal landed-cost file or supplier quote still reflects the former anti-dumping or countervailing treatment, the importer may need to reconcile the commercial record with the customs record. Any adjustment should be based on the applicable release and product facts.
For earlier releases, the relevant question is whether the goods were covered and released on or after March 25. Importers who paid eligible duties generally do not need to treat the refund as a new tariff claim: CBSA says the refunds will be automatic. They should nevertheless retain entry-level records so the refund can be matched to the original release and accounting records.
For companies receiving goods into Peel Region warehouses or distributing through the GTA, this review is most useful when connected to the shipment file rather than handled only as a general tariff master-data change. The objective is to separate covered photovoltaic goods from other products, preserve the release-date evidence and prevent the rescission from being applied to goods outside the product definition.
Bottom line
The September 17 rescission changes the duty treatment for new releases of covered Chinese photovoltaic modules and laminates and creates a stated automatic-refund window for eligible releases from March 25 onward. Importers should use the notice’s product definition, not tariff classification alone, to determine scope. A release-date and product-level reconciliation is the most direct way to identify affected entries while avoiding unsupported refunds or incorrect treatment of unrelated goods.
