SIMA Duty Lookup

The Special Import Measures Act (SIMA) is Canada's trade remedy legislation. It allows the Canada Border Services Agency (CBSA) to impose anti-dumping and countervailing duties on imported goods that are being dumped (sold below fair market value) or subsidized by foreign governments, when this causes or threatens injury to Canadian industry.

Anti-dumping duties are additional charges imposed on imported goods that are being sold in Canada at prices below their normal value in the exporter's home market. The duty amount is calculated to offset the price difference (the "margin of dumping"). These duties are specific to the exporting country and sometimes to individual exporters.

Countervailing duties are imposed on imported goods that have benefited from government subsidies in the country of origin. These duties offset the unfair competitive advantage created by the subsidy. Like anti-dumping duties, they are country-specific and can vary by exporter.

Use this tool to search by your product's HS code or description and optionally filter by country of origin. If your product matches an active SIMA finding, you'll see the applicable duty rates. You can also check CBSA's official measures-in-force page for the authoritative list of active SIMA measures.

SIMA duties significantly increase your total duty exposure on affected imports. Since customs bond amounts are based on your estimated annual duty payments, importing goods subject to anti-dumping or countervailing duties typically means you'll need a higher bond amount. This applies to both single-entry and continuous bonds.

SIMA measures are reviewed periodically through expiry reviews (typically every 5 years) and can be subject to interim reviews. The CBSA and Canadian International Trade Tribunal (CITT) manage these reviews. Measures can be continued, varied, or revoked. New investigations can also result in new measures at any time.
