How to provide CBAM data to an EU importer?

Non-EU suppliers must provide their EU importers with emissions data formatted specifically for the CBAM Transitional Registry. Carbon Mandate provides an expert-led service that takes your raw facility data, checks the methodology via human specialists, and generates the exact XML file your importer requires to clear customs.

What is the CBAM XML format generator for iron and steel?

The EU Commission requires CBAM data in a strict XML format. Rather than relying on automation alone, which can misinterpret heavy industry metrics, Carbon Mandate prepares machine-readable XML files for Iron, Steel, Aluminium, and Cement exporters through an expert-led, human-in-the-loop pipeline.

An EU importer is requesting CBAM data, what do I do?

Send us your existing domestic certificates or raw facility data for a diagnostic scan. We will map your data to the required CN codes and prepare the exact XML deliverable your EU buyer needs.

FAQ

Common questions from non-EU exporters.

Does the default emission factor differ for primary versus secondary aluminium?Yes. IR (EU) 2025/2620 Annex II publishes separate default values. Primary aluminium produced via the Hall-Héroult electrolysis process carries substantially higher embedded emissions (principally from electricity) than secondary aluminium produced from recycled scrap. Carbon Mandate applies the correct default automatically based on your declared production route.

Carbon Mandate applies the correct default automatically based on your declared production route.

How are indirect emissions from electricity handled in the XML?CBAM requires both direct (Scope 1) and indirect (Scope 2 electricity) emissions for aluminium. If you use actual electricity consumption data with a verified grid emission factor, those values populate the XML. If not, the Annex II default includes a combined direct and indirect value. You declare which basis applies.

My EU importer is asking for an XML. What does Carbon Mandate actually produce?Carbon Mandate prepares machine-readable CBAM XML, checked against the declaration structure the Commission has specified. The Commission has not yet published a definitive annual-declaration XSD. We produce an XML declaration with the full precursor chain intact, not a PDF report or a spreadsheet template.
