CBAM for Non-EU Exporters: What Your EU Buyers Will Ask For, and How to Keep the Contract

If you manufacture steel, aluminium, cement, fertilisers, hydrogen or electricity outside the EU and sell into it, CBAM does not make you file anything with a European authority. Your EU customer is the authorised declarant. But the customer cannot do its job without your data, and that is where the pressure lands. In the words of one practitioner guide, CBAM creates no direct legal obligation for non-EU exporters but "an immediate commercial obligation to provide verified embedded emissions data" (CBAM guide for exporters).

This guide is a checklist of what your buyers will ask for and how to get ready, written for the installation operator or export sales manager rather than the EU importer.

What EU buyers will request

Expect four categories of installation-level information (CBAM guide for exporters).

Installation identification. Legal name and physical address, a UN/LOCODE location code, geographic coordinates, a steel mill ID for steel products, and a named CBAM contact person.

Embedded emissions data. Only two calculation approaches are accepted: equation-based (activity data multiplied by emission factors) or mass-balance (carbon inputs minus outputs). What counts depends on the sector. Iron and steel and hydrogen are reported on direct emissions. Cement and fertilisers include direct and indirect (electricity) emissions. Aluminium includes CO2 and perfluorocarbons.

Precursor emissions. For complex goods, the embedded emissions of each CBAM-listed input must be itemised separately.

Carbon price evidence. If your country operates a qualifying carbon pricing scheme, your buyer can deduct the carbon price already paid from its certificate obligation under Article 9. To support that, you need the amount paid per tonne (excluding free allocation and rebates), the scheme name and legal basis, and proof of payment such as an invoice or registry record. Voluntary offsets and shadow prices do not qualify.

The Commission published its recognition framework for third-country carbon prices on 13 May 2026, and the consultation closed on 10 June. As of July 2026, one source reports that no scheme, including South Korea's K-ETS, had been formally recognised (CBAM guide for exporters). Check the current status before promising a buyer a deduction.

Verification is not optional if you want actual values

Data submitted as actual emissions must be verified by an accredited verifier. Practitioners note that verifiers need EN ISO/IEC 14065 accreditation, and that physical site visits remain mandatory for 2026 verification periods (SCS Global Services). One guide puts verification costs at EUR 5,000 to EUR 50,000 per installation depending on complexity; treat that as a third-party estimate, not an official figure (CBAM guide for exporters).

Timing matters. The Commission opened verifier registry registration on 1 September 2026, and capacity in late 2026 is tight. Our post on the verifier bottleneck explains why booking a slot is the real decision.

The Commission's CBAM Operators Portal lets you upload data once and make it available to several EU buyers. Use of the portal is voluntary, so a buyer may still ask for data through its own template or channel.

Why default values hurt you

If you cannot supply verified actual data, your buyer must use Commission default values. These are set deliberately high and carry a mark-up of 10% in 2026, 20% in 2027 and 30% from 2028 (CBAM guide for exporters). The same source cites Chinese steel slab at a default of 3.167 tCO2e per tonne against actual emissions of roughly 1.8 to 2.1.

That gap is a pricing problem for you, even if the invoice goes to your buyer. A buyer that faces a higher certificate cost on your product will either ask for a discount or move volume to a supplier with verified data. Our default values explainer covers the mechanics in more detail.

The official guidance to use

On 14 August 2026 the Commission published ten guidance documents. Guidance No 2 is a quick guide for non-EU operators, No 3 covers methods for calculating embedded emissions, and Nos 5a to 5f are sector guides for cement, hydrogen, fertilisers, iron and steel, aluminium and electricity (guidance summary). If you read only one thing this month, read the guide for your sector.

An exporter's readiness checklist

1. Name a CBAM owner internally and register a contact with each EU buyer.
2. Build installation records: legal identifiers, UN/LOCODE, coordinates, mill ID.
3. Document your monitoring method and choose between the equation-based and mass-balance approach for each product.
4. Map precursors for any complex goods you sell.
5. Collect carbon price evidence if your country has a scheme, and keep it ready without assuming recognition.
6. Book a verifier and plan the site visit.
7. Compare your default-value exposure with your verified numbers to quantify what verification is worth per product line.
8. Agree in writing with your buyers who supplies what, and who bears cost differences. Our Incoterms guide shows how liability allocation works in the contract.

FAQ

Does CBAM apply to my company directly if I am outside the EU? Not as a filer. The EU importer is the authorised declarant, but it will depend on your data.

Do I have to use the CBAM Operators Portal? No. It is voluntary, and buyers may accept data through other documented channels.

Can my buyer deduct the carbon price we pay at home? Only for qualifying, legally binding carbon pricing schemes, with proof of payment. Recognition of specific third-country schemes was still pending in the sources we reviewed.

What if I only sell small volumes? A 50-tonne mass-based de minimis exemption exists for importers, but it is all-or-nothing and excludes hydrogen and electricity. See our guide before assuming you are covered.
