CBAM 2026 Definitive Regime and the 50-Tonne Threshold: Do Not Treat It as a Permanent Release

Source basis checked on 2026-08-06. This article is based on European Commission, EUR-Lex and CBAM official materials. It is preparation guidance and does not promise regulatory acceptance, platform display, sales, customs release, tax outcome, authorisation or certification result.

The threshold belongs to a specific obligation question

The 2026 CBAM Questions and Answers explain that, from 1 January 2026, importers of CBAM goods generally need authorised CBAM declarant status, while importers of CBAM goods other than hydrogen and electricity do not need authorisation if they remain below the annual single-mass threshold of 50 tonnes. Hydrogen and electricity importers always need authorisation.

This point is useful, but it is often misread. The threshold is not a simple supplier exemption. It is assessed on the importer side, by year and by relevant goods. A supplier usually does not have enough information to decide the importer's full annual position.

Why suppliers still need a data file

An importer may be below the threshold today and above it later. A customer group may consolidate imports across orders. A product may change code or route. The importer may ask for data in advance to avoid reconstructing it after the reporting year. For suppliers, the practical question is not 'can we ignore CBAM below 50 tonnes?' but 'what minimum records should we preserve if our EU customer asks later?'

Official CBAM materials also point to important 2027 milestones. For 2026 imports, the first annual CBAM declaration and certificate surrender are due by 30 September 2027, and certificate sales begin in February 2027. Waiting until 2027 to search for 2026 production data is a weak position.

A sensible minimum file

For possible CBAM goods, keep the EU customer, order, CN code, production facility, production period, quantity, process route and basic energy or production data source. If the importer later confirms that the goods are outside scope or below the relevant threshold, the file can remain light. If the importer needs actual data, the supplier has a starting point.

Greenark Certification can help separate threshold questions from supplier data readiness and avoid wording that sounds like an official exemption conclusion.
