Documentation you will be asked for: ・Embedded carbon emissions for each shipment (provided by you, the non-EU producer; the importer cannot calculate this themselves) ・Production facility data: location, manufacturing process, source of raw materials ・If the buyer imports less than 50 tons per year of controlled goods total, they are exempt from declaration—if the volume is small, ask the buyer whether they exceed this threshold
What you should do now: 1. Confirm your tariff code first. Reporting the same product under 7326 or under a finished product code makes a completely different outcome—confirm the 8-digit code you actually use with your customs broker. 2. Ask your EU buyer two things: does he import more than 50 tons per year of controlled goods in total (if not, he's exempt from declaration), and has he applied for Authorized Representative status? 3. Start maintaining production records: electricity, fuel, and raw materials (steel blanks, aluminum ingots) used in each process, their sources, and quantities. Without actual data you can only use EU default values, which are intentionally set high. 4. Request data from upstream suppliers: the carbon emissions of the steel and aluminum materials you purchase must be provided by the steel mills and aluminum mills; this usually represents the largest portion. 5. Emission data must be verified by an EU-approved verification body. Understand the process early. Factories can also register themselves in the EU's CBAM registration system—data entered once can be shared with multiple buyers.
