CBAM for hydrogen imports: requirements and workflow

Hydrogen importers need clear evidence on production method, emissions intensity, and customs classification before declaration data is prepared. This guide explains how to turn the topic into a practical import, review, and declaration workflow.

How to make this practical

01

Clarify scope

Bring affected HS/CN codes, suppliers, and goods flows into one review list.

02

Review data

Check quantities, supplier evidence, and emissions values before declaration.

03

Export a working package

Reviewed data becomes a reliable annual working package for the registry workflow.

Context

Operational context

In the definitive CBAM regime, import data should be maintained continuously and reconciled during the year, while the legal CBAM declaration covers the preceding calendar year. Keep scope decisions, source data, supplier evidence, emissions reviews, and approvals together in one audit trail. CBAM-OK creates a structured annual working package for entry in the CBAM Registry or review by an adviser. It does not submit a declaration automatically and does not currently label an XML file as filing-ready.

Common questions

What is the first practical step?
Bring HS/CN codes, suppliers, quantities, countries of origin, and product groups into one review list before building reports or exports.
Which data should be checked before declaration?
Check customs codes, imported quantities, supplier emissions data, default-value assumptions, production route, and evidence files.
How does CBAM-OK help?
CBAM-OK keeps classification, supplier data, review status, evidence, and export history in one auditable workflow. It creates an annual working package for registry entry or adviser review; filing remains the authorised declarant’s responsibility.
What should remain documented?
Keep source data, supplier responses, assumptions, reviewer decisions, and generated exports together for audit readiness.
