Which sectors does CBAM cover?
Six: iron and steel, cement, fertilisers, aluminium, hydrogen and electricity, always identified by the tariff codes listed in the annex to the regulation. Source: European Commission, official CBAM page, September 2026.
There is a size filter that changed life for low-volume flows. Importers bringing in less than 50 tonnes net of CBAM goods per calendar year need no authorisation and carry no obligations under the mechanism, with two exceptions: hydrogen and electricity always require an authorised declarant, at any volume.
The cut-off applies per importer, not per shipment, and it is measured by the net mass declared in the customs declaration. Check your product classification before assuming you are out of scope, because reading the HS code correctly is what decides whether a good sits in the annex.
