How to Prepare a CBAM Declaration? Step-by-Step Guide

After calculating your embedded emissions in the calculator's CBAM tab, what's next? In this guide, we explain exactly what the draft declaration template generated by the platform's CBAM tab contains, how to generate it, and — most importantly — why this document does NOT substitute for an official declaration.

For how CBAM works in general, the transition timeline, and the certificate cost formula, we recommend first reading our general CBAM guide.

What Does the CBAM Declaration Template Contain?

The "Download Declaration Template" feature in the calculator's CBAM tab converts your calculation result into a three-section PDF:

1. Declarant (Exporter) Information: Company/declarant name, tax ID/office, facility/installation name, country of origin.

2. Product and Embedded Emissions Information: Product name, CBAM sector, CN code (entered manually), the sector's CN code range (indicative), exported quantity (tons), reference year, total embedded emissions (kg CO2e), and embedded emissions per ton of product.

3. Estimated CBAM Certificate Cost: An estimated cost calculated using the EU ETS reference price (€72.5/ton CO2e).

Step-by-Step: How to Generate the Declaration Template

1. Run the calculation in the CBAM tab: In the calculator's CBAM, PCF & Risk tab, enter your product type, exported quantity, and reference year, then click "Calculate."

2. Fill in the additional declaration fields: Enter your CN code (confirmed with your customs broker), country of origin, and facility/installation name.

3. Click "Download Declaration Template": The template is automatically downloaded as a PDF pre-filled with your company information, product details, and calculated emission values.

4. Review the PDF and share it with your customs broker: The document serves as a starting point for internal preparation and discussion with your broker before an official submission.

Important: This Is Not an Official Declaration

As clearly stated on every page of the generated PDF: this document is NOT an official form that can be uploaded directly to the EU CBAM Transitional Registry — it is only an internal DRAFT for preparation/summary purposes. The CN code is entered manually by the user (the platform only offers the sector range as an indicative reference) and must always be confirmed with your customs broker before an official submission. The methodology used (IPCC AR6 GWP-100 multipliers, coefficients from our Bibliography page) consists of engineering approximations; an official declaration may require a verified emissions report.

CN Code Ranges by Sector (Indicative)

The CN (Combined Nomenclature) code ranges the platform offers as an indicative reference for each CBAM sector:

These ranges are indicative only — always confirm your product's EXACT CN code with your customs broker. For the full coefficient list of each sector's product sub-categories, see the CBAM section of our Bibliography page.
