EU CBAM in 2026: What Non-EU Producers Must Prepare Now
CBAM is no longer a quarterly transitional-reporting exercise. The definitive period began on 1 January 2026, placing monitoring, reporting and financial obligations on authorised EU declarants and making the quality of installation-level evidence commercially important for non-EU producers.
The European Commission published corrected definitive-period default values on 10 August, a ten-document operator guidance package on 14 August, and Registry access guidance for accredited verifiers on 28 August. Its state-of-play note on CBAM accreditation was published on 24 July.
Start with product classification and installation boundaries
Confirm the relevant CN codes, production routes and whether the goods fall within the cement, iron and steel, aluminium, fertilisers, hydrogen or electricity scope. Map each installation, production process and measurable heat, fuel, electricity and material flow. The boundary must explain which processes produce the CBAM goods and how shared emissions are attributed.
Simple and complex goods require different evidence
For complex goods, the embedded emissions of relevant precursors form part of the product result. Producers therefore need controlled supplier data, production quantities and allocation rules—not only a facility total. Direct emissions are central across covered goods; indirect emissions are included only where required by the Regulation and implementing acts.
Actual values and defaults are a strategic choice
EU declarants may use applicable default values or actual verified emissions. Actual values can preserve a producer’s carbon-performance advantage, but they require monitored source data, documented calculation methods, an operator emissions report and accredited verification. Corrected default values were published on 10 August 2026; the legally binding values remain those in the relevant implementing regulation.
Build the 2026 verification file now
- CN-code and product-to-route mapping.
- Installation boundary, process flow and precursor register.
- Monitoring plan identifying meters, methods, owners and data-retention controls.
- Production, fuel, material, electricity and precursor records linked to calculations.
- Allocation logic for shared processes and complex goods.
- Direct and, where applicable, indirect embedded-emissions calculations.
- Evidence supporting the free-allocation adjustment inputs and any carbon price effectively paid.
- Issue log, management review and controlled operator emissions report.
The first annual declaration for 2026 imports and the corresponding surrender of CBAM certificates are due by 30 September 2027. A 50-tonne annual threshold generally applies to covered goods other than electricity and hydrogen.
The verifier accreditation application has been formally accepted by ACCREDIA and the assessment process is underway. CBAM verification will only be offered as an accredited service after formal accreditation is granted and within the approved scope.
