The EU Carbon Border Adjustment Mechanism (CBAM) prices embedded emissions on selected imported goods so that carbon costs converge with the EU Emissions Trading System logic. Chinese exporters of in-scope products—and their EU importers—need emissions data, monitoring methodology, and contractual allocation of CBAM obligations.

What CBAM is trying to do
CBAM is established under Regulation (EU) 2023/956 of the European Parliament and of the Council of 10 May 2023 establishing a carbon border adjustment mechanism (as implemented and phased by subsequent Commission acts—always confirm the phase applicable to your reporting period). During transitional phases, reporting obligations dominate; definitive phases introduce certificate surrender aligned with embedded emissions, with adjustments related to free allocation logic under the EU ETS design.
CBAM is not a traditional customs duty schedule you can “engineer” only with invoice tricks. It is an emissions-accounting and compliance product attached to imports.
Scope — start from the regulation annexes
Initial CBAM goods include categories such as cement, electricity, fertilisers, iron and steel, aluminium, and hydrogen (see Annex I of Regulation (EU) 2023/956 and updates). Downstream products and expansions are a political and regulatory watch item—re-check scope when your BOM changes or when you sell further-processed goods.
If your product is out of scope today, still track precursors: steel and aluminium inputs can pull customers into CBAM data requests even when your finished SKU is not listed.
Who does what
- EU importers / CBAM declarants — typically bear formal reporting and, later, certificate obligations under EU law
- Non-EU producers / exporters — must supply verified or default emissions data, production routes, and installation information or lose sales to competitors who can
- Traders — intermediate parties must preserve data continuity across multi-hop supply chains
Emissions data file (exporter view)
- Map installations and production routes for each in-scope CN code
- Collect direct and relevant indirect emissions per implementing methodology
- Document quality system; prepare for verification where required
- Align commercial invoices and shipment IDs so importers can match reports
- Version the file when processes, fuels, or electricity sources change
Default values may apply when actual data are missing—usually commercially painful. Investing in actual data is often cheaper than losing EU customers.
Contract allocation
Sales contracts should state who provides CBAM data, who pays for verification, remedies for late or inaccurate data, and audit rights. Dispute forums for cross-border supply remain critical—see arbitration forum guide. Document authentication for corporate authorizations may need Apostille when foreign registries or counterparties require it.
Next steps
Trade defence, investment screening, and host-country employment rules change by regulation and case practice. Confirm the instrument version and investigation notice that apply to your products or deal before you file, price, or ship.
