Three mistakes importers make with the complete CBAM framework

❌

MISTAKE 1 — READING ONLY ART. 6 (DECLARATION)

Ignoring the web of supporting obligations

The declaration is the most visible obligation, but it depends on all the others: authorisation, emissions calculation, certificate purchases, verification, records. Missing any one creates a compliance gap.

❌

MISTAKE 2 — MIXING TRANSITIONAL AND DEFINITIVE RULES

Applying 2023–2025 transitional rules to the 2026+ regime

The transitional period was reporting-only, no certificates, no penalties. The definitive regime has financial obligations. Do not apply transitional rules.

❌

MISTAKE 3 — NOT READING THE ANNEXES

Focusing on articles but ignoring Annex I, III, IV, V

The annexes contain the operational detail: which CN codes (Annex I), which countries are exempt (Annex III), how to calculate emissions (Annex IV), what records to keep (Annex V). The articles define obligations; the annexes define how.

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 your declaration in the CBAM Registry.

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 rate

EU ETS rate per 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 per Art. 16(4). The penalty applies per certificate not surrendered. 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): anyone introducing goods without authorisation faces a penalty of 3 to 5 times the standard penalty, depending on duration, gravity, scope, intent and cooperation. Also applies to importers exceeding the de minimis threshold (50 tonnes, Art. 2a) without authorisation (Art. 26(2a)).
