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 automated software that can misinterpret heavy industry metrics, Carbon Mandate prepares registry-ready 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?

Do not risk registry rejection with generic software. Upload your existing domestic certificates or raw facility data to Carbon Mandate 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 CBAM apply to non-EU exporters directly?

CBAM is paid and filed by the EU importer of record. But the file they submit is built on installation-level emissions data the non-EU exporter supplies. If your data is missing or wrong, your EU buyer falls back to default values and the cost lands back on you in the next contract.

What does Carbon Mandate do for non-EU exporters?

We are a preparer, not a filer, and never the verifier. Expert-reviewed installation-level data goes in; a CBAM XML prepared to the EU CBAM schema comes out. Your EU buyer submits it as the authorised CBAM declarant.

Which sectors are in scope?

Annex I of Regulation (EU) 2023/956 covers iron and steel, aluminium, cement, fertilisers, electricity, and hydrogen — including downstream goods like screws, tubes, and structural sections.

How much can default values cost?

Implementing Regulation (EU) 2025/2621 applies a markup on top of the default emissions value to incentivise reported actuals — 10% in 2026, 20% in 2027, and 30% from 2028 onwards across iron and steel, aluminium, and cement. Default values themselves are typically set well above installation-level actuals, so the per-tonne CBAM cost is materially higher when measured facility data is missing.

Does Carbon Mandate file with the EU Registry?

No. We never file and we never verify. We prepare the data and the XML; your EU buyer submits as authorised CBAM declarant under Article 6 of Regulation (EU) 2023/956 (as amended by Regulation (EU) 2025/2083).
