Senseible

Can the same imported tonne be declared by two CBAM declarants?

No. Every tonne of imported goods is the responsibility of exactly one authorised CBAM declarant: the person lodging the customs declaration, usually the importer or an indirect customs representative. It must not be reported twice or left out.

Why it matters to you

How customs links it

Each import declaration carries the declarant's CBAM account number, and customs data flows into the CBAM Registry to check declarations.

What Senseible does here

Senseible keeps supplier invoices and the emissions data that comes with them in one dated, fingerprinted record per shipment, and its CBAM cost calculator estimates certificate cost from 2026 to 2034. Senseible does not verify emissions, register declarants or file CBAM declarations.
