CBAM Registry data: what belongs in the annual working package?
A reliable CBAM declaration starts with reviewed source data, not a file extension. This article explains what belongs in the annual working package and where the authorised declarant or adviser still needs to work in the official CBAM Registry.
How to make this practical
Clarify scope
Bring affected HS/CN codes, suppliers, and goods flows into one review list.
Review data
Check quantities, supplier evidence, and emissions values before declaration.
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.
