The EU Carbon Border Adjustment Mechanism moves from the transitional reporting period toward the definitive paid phase. Exporters of iron and steel, aluminium, cement, fertilisers, electricity, hydrogen and covered downstream goods should not wait until shipment to assemble emissions evidence. The practical task is to connect product scope, CN code, production data, embedded-emissions calculation, verifier files and importer reporting responsibility before the order reaches EU customs.
What changes in the definitive phase
During the transitional period, importers focus on quarterly CBAM reports. In the definitive phase, CBAM declarations and certificate surrender become part of the compliance workflow. The exact cost depends on product scope, embedded emissions, applicable EU ETS-linked certificate prices, any eligible carbon price paid in the country of origin, and the importer declaration route. This article does not predict a guaranteed cost or customs result.
Exporter evidence checklist
| Evidence item | Why it matters |
|---|---|
| CN code and covered product scope | Confirms whether the SKU falls within the CBAM product annex. |
| Production route and facility data | Supports the embedded-emissions calculation and data traceability. |
| Default-value or actual-value method | Determines the evidence depth and verifier involvement needed. |
| Importer and authorised declarant responsibility | Clarifies who files, buys certificates and keeps records. |
Action path before export
Build a product-level ledger before the sales team quotes EU orders. Start with product scope, map each covered SKU to its facility and production route, decide whether default values or actual values are being used, collect source data and verification files, then align the handoff with the EU importer. If the product is outside CBAM scope, keep the reasoning and CN-code review record because platform, buyer or customs questions may still require evidence.
Service boundary
Greenark (Shenzhen) Certification Co., Ltd. can support CBAM product-scope review, carbon-data ledger design, embedded-emissions evidence mapping and importer handoff preparation. The service supports evidence readiness and workflow review; it is not an official decision and does not guarantee customs clearance, certificate cost, platform acceptance or commercial results.
