How to prepare and submit your annual CBAM declaration under Art. 6 — first deadline 30 September 2027 for calendar year 2026

You need to submit a CBAM declaration and you need to understand exactly what it contains, when it is due, and how to prepare the data. Under Art. 6 of Reg. (EU) 2023/956, every authorised CBAM declarant must submit an annual declaration to their national competent authority by 30 September of each year for the preceding calendar year. The declaration must include: total quantity of each type of goods imported (Art. 6(2)(a)), total embedded emissions (Art. 6(2)(b)), total number of CBAM certificates surrendered (Art. 6(2)(c)), and copies of verification reports (Art. 6(2)(d)). CBAMCheck generates a draft declaration pre-structured per Art. 6(2) as one of its 12 deliverables. €299 one-time.

Your CBAM compliance timeline

Understand what the declaration requires
Art. 6(2): (a) total quantity per good type, (b) total embedded emissions, (c) total certificates surrendered net of Art. 31 adjustment, (d) copies of verification reports per Art. 8.
2
Gather your import data for calendar year 2026
All imports of CBAM goods from 1 January to 31 December 2026. CN codes, quantities in tonnes, countries of origin, installation data.
3
Calculate embedded emissions
Art. 7 + Annex IV. Default values or verified actuals. CBAMCheck automates this calculation.
4
Document any Art. 9 carbon price deduction
If applicable, include carbon price documentation certified by an independent person.
5
Ensure verification is complete
Art. 8: verification by accredited verifier. Report must be ready before submission deadline.
6
Submit via the CBAM Registry by 30 September 2027
Art. 6(1). The declaration is submitted electronically through the CBAM Registry to your NCA.

Three mistakes that inflate your CBAM cost or create compliance risk

MISTAKE 1 — WRONG DEADLINE

Missing the 30 September deadline

Art. 6(1) sets 30 September as the annual deadline. Missing it triggers Art. 26 penalties. CBAMCheck’s compliance calendar (.ics) puts every deadline in your agenda.

MISTAKE 2 — INCOMPLETE DATA

Submitting a declaration without all four Art. 6(2) elements

The declaration must include quantities, emissions, certificates and verification reports. Missing any element makes it incomplete.

MISTAKE 3 — TRANSITION CONFUSION

Using transitional period reporting formats for the definitive phase

The transitional period (2023–2025) used CBAM reports. The definitive phase (from 2026) uses annual declarations under Art. 6 with different requirements. CBAMCheck generates definitive-phase documentation.

The EU CBAM portal asks for data. CBAMCheck calculates it.

THE EU CBAM PORTAL

Asks you to declare data

The EU CBAM Registry (Art. 14) requires you to submit total embedded emissions, number of certificates and carbon price documentation. It does not calculate these for you. You must arrive with the numbers ready.

CBAMCHECK

Calculates the data you need to declare

CBAMCheck takes your import data (tonnes, CN codes, country of origin) and generates the embedded emissions calculation, certificate estimation, carbon price documentation and all supporting records. You download the dossier and use it to complete the CBAM Registry submission.

Enforcement: what happens when CBAM certificates are missing

Art. 26 of Reg. (EU) 2023/956 sets the penalties.

⚠️
Authorised declarant: penalty identical to EU ETS excess emissions penalty
EU ETS rate per missing certificate

Art. 26(1): an authorised CBAM declarant who fails to surrender the required certificates by 30 September faces a penalty identical to the excess emissions penalty under Art. 16(3) of Directive 2003/87/EC, increased pursuant to Art. 16(4). Payment does not release the obligation to surrender outstanding certificates (Art. 26(3)).

⚠️
Unauthorised importer: penalty 3–5 times the standard rate
3–5×

Art. 26(2): a person who introduces goods without authorisation faces a penalty of 3 to 5 times the standard penalty. This also applies to importers exceeding the de minimis threshold (50 tonnes, Art. 2a) without authorisation (Art. 26(2a)).
