Short answer

The EU CBAM definitive regime began on 1 January 2026. The importer should verify the exact CN code is in scope and check the authorized-declarant requirement and exceptions for imports exceeding 50 tonnes of CBAM goods. Not every transport container is covered. Request supplier data only after confirming code and product scope.

The EU CBAM definitive regime began on 1 January 2026. First, the importer should match the goods' exact CN code to the current EU scope annex; a container or equipment label alone does not determine scope.

For imports exceeding 50 tonnes of in-scope goods, the importer or representative should check the authorized-declarant requirement and current exceptions. File country, code, goods group and period.

Request installation and embedded-emissions data only after confirming scope. Record source, method and data owner; confirm the declaration role with the EU importer.
