CBAM Declaration: Who, When and What?

CBAM Declaration: Who, When and What?

Last updated: November 2026

The CBAM definitive period at a glance

When?
The definitive period started on 1 January 2026. The first annual CBAM declaration, covering 2026 imports, is due by 30 September 2027 in the EU CBAM Registry. After that, each declaration is due by 30 September for the previous calendar year.
Who declares?
The obligated party is the EU importer or its indirect customs representative, acting as an authorised CBAM declarant. The non-EU producer or exporter does not file the declaration; it supplies the installation-level embedded emissions data.
What is the threshold?
Regulation (EU) 2025/2083 introduced an annual threshold of 50 tonnes net mass per importer. An importer whose CBAM goods stay at or below 50 tonnes in a calendar year is exempt from the obligations. Hydrogen and electricity imports are not covered by this exemption.
Verification
Declared actual emissions must be verified by an accredited CBAM verifier. The installation operator contracts the verifier, who checks the operator's embedded emissions calculation; the report is then used in the importer's declaration.

What is CBAM?

The Carbon Border Adjustment Mechanism (CBAM) puts an obligation on the emissions embedded in goods such as cement, iron and steel, aluminium, fertilisers, hydrogen and electricity imported into the EU, equivalent to the carbon price paid by producers inside the EU. Its purpose is to prevent carbon leakage and encourage emission reductions outside the EU.

How CBAM Works: Step-by-Step Process

Embedded emissions are monitored and calculated at installation level, using the methods set out in the EU CBAM implementing rules. The process has three steps:

  • Data Collection: Data on carbon emissions from the production process of products is collected. This data includes factors such as the amount of energy used in production, raw material consumption, and other environmental impacts.

  • Calculation: The collected data is calculated according to established standards. These calculations follow the EU CBAM implementing rules.

  • Reporting: The calculated data is presented in CBAM declaration reports. These reports allow businesses to transparently demonstrate their carbon footprint and meet compliance requirements.

Data Tracking and Management: Challenges and Solutions

To manage your CBAM declarations, you need to track your data accurately and efficiently. Here are some challenges you may encounter in data tracking and management, along with possible solutions:

  • Difficulty in Data Collection: Accurately calculating all carbon emissions in production processes and gathering this data is a complex process. Factors such as the amount of energy used in production, raw material consumption, and other environmental impacts must be taken into account.

  • Accurate Calculations: Correctly calculating the collected data is critical for the accuracy of CBAM declarations. These calculations must follow the EU CBAM implementing rules.

  • Reporting and Compliance: The calculated data must be accurately reported and presented as CBAM declaration reports. These reports allow businesses to transparently demonstrate their carbon footprint and meet compliance requirements.

What will my EU customer ask me for?

Your EU customer files the CBAM declaration, but the actual emissions data in it comes from your installation. Expect to be asked for the CN code and installation details of the goods you ship, their direct and indirect embedded emissions per tonne, and an accredited verifier's report confirming those figures.

  • Installation and product details: Name, address and location of the production installation, the production route and the CN code of the goods.

  • Embedded emissions: Direct and indirect emissions per tonne of product (tCO₂e/t) for the reporting period, the monitoring method used and the emissions of any precursor goods.

  • Verification report: A report from an accredited CBAM verifier for actual emissions. If actual data is not available, the importer may use the default values published by the Commission.

  • Carbon price paid (if any): Evidence of any carbon price effectively paid in the country of origin. This can be used to reduce the number of CBAM certificates the importer has to surrender.

What goes into the annual CBAM declaration?

The authorised CBAM declarant declares, for the previous calendar year, the total quantity of each type of goods imported, the total embedded emissions in those goods, the accredited verifiers' reports and the number of CBAM certificates to surrender. That number is adjusted for any carbon price paid in the country of origin and for EU ETS free allocation.

  • Quantity: Total imports of each type of goods in tonnes (MWh for electricity).

  • Embedded emissions: Total embedded emissions (tCO₂e) and their breakdown by installation.

  • Certificates: The number of CBAM certificates to surrender for those embedded emissions.

Ease of use and automated reporting — 60% faster than manual calculation.

Conclusion and Recommendations

The CBAM definitive period has started and EU importers are asking their suppliers for verified emissions data. CarbonEmit helps you keep that data organised, traceable and declaration-ready with CN code mapping, installation-level embedded emissions and Excel/XML export.

CBAM frequently asked questions

Does the non-EU exporter file the CBAM declaration?

No. The EU importer or its indirect customs representative files it as an authorised CBAM declarant. The non-EU producer or exporter supplies verified embedded emissions data for the goods produced in its installation.

When is the first CBAM declaration due?

The first annual CBAM declaration, covering goods imported in 2026, is due by 30 September 2027. In later years, the declaration is due by 30 September for the previous calendar year.

How does the 50-tonne threshold work?

The threshold introduced by Regulation (EU) 2025/2083 looks at the cumulative net mass of CBAM goods imported by one importer in a calendar year. Importers at or below 50 tonnes are exempt from the obligations. Hydrogen and electricity imports do not benefit from this exemption.

Which products does CBAM cover?

In the definitive period CBAM covers goods in the cement, iron and steel, aluminium, fertilisers, hydrogen and electricity sectors, listed by CN code in the annex to the Regulation.

What happens if actual emissions data is not available?

If verified actual data cannot be provided, the importer may use the default values published by the European Commission. Where actual data is used, the emissions must be verified by an accredited CBAM verifier.

Is CBAM a tax?

CBAM is a mechanism built on an obligation to surrender CBAM certificates for the emissions embedded in certain goods imported into the EU. The certificate price is linked to the EU Emissions Trading System (EU ETS) price.

Where does CarbonEmit store my data?

Customer data is hosted in the AWS Istanbul region. Marsala Yazılım A.Ş., the company behind CarbonEmit, holds ISO 27001 and ISO 42001 certificates.
