The October 2026 CBAM Q&A: one change, on Northern Ireland
The Commission's CBAM Q&A is the document most teams check first when a rule is unclear. A new edition appeared on 15 October 2026, with the same 63 pages as the May edition. It is published on the Commission's "CBAM communication and news" page, under frequently asked questions.
We converted both editions to text and compared them. Apart from Northern IrelandNorthern IrelandThe UK territory subject to specific customs and EU-law interactions under the Windsor arrangements., every answer reads as it did in May. Nothing changed on scope, calculation, default values, verification, certificates or the declaration.
What changed: the Northern Ireland answers
The section on Northern Ireland sits in the customs chapter. Four answers in it changed:
- The legal reference. The answers now cite the Windsor FrameworkWindsor FrameworkThe UK-EU framework governing important aspects of trade and customs treatment involving Northern Ireland., the current name of the Protocol on Ireland/Northern Ireland. The articles cited for the customs code in Northern Ireland are now Articles 5(3), 5(4) and 13(1) and Annex 2, instead of Articles 4 and 13(1).
- The basic position is unchanged. CBAM does not apply in Northern Ireland, and Northern Ireland is not part of the EU customs territory.
- The routing answer is wider and sets one test. It used to cover only goods of British origin moved from Northern Ireland into the EU. It now covers goods from Great BritainGreat BritainEngland, Scotland and Wales as a territorial label used in UK customs and trade analysis. and from third countries that transit Northern Ireland. They are subject to CBAM when they are released for free circulation in the EU.
- A new sentence draws the line. Goods produced in Northern Ireland, or released for free circulation there, are not subject to EU CBAM.
What the Q&A no longer says
The May edition had a separate answer: companies established in Northern Ireland must use an indirect customs representativeIndirect customs representativeEU-established representative who may act as CBAM declarant; mandatory for non-EU importers, optional for EU importers. One per customs declaration; legal responsibility never moves with delegated technical submission. to release CBAM goods from third countries into free circulation in the EU. The October edition removes that answer and puts nothing in its place.
Read this carefully. A Q&A does not amend the Regulation, and the Regulation's rules for importers not established in the EU have not changed. Removing an answer is not a statement that the requirement has gone. If you relied on that answer, confirm your arrangement with your customs representativecustoms representativeA person appointed to perform customs acts and formalities for another person..
The question numbers moved
One question was removed and one added, so the customs chapter is renumbered from question 7.15 onwards. If your own documents cite the Q&A by number, check them against this table.

What to do
If none of your EU imports pass through Northern Ireland, nothing changes for you. If some do, find the customs record for each route and note where the goods were released for free circulation. If release happens in the EU, EU CBAM applies to that import. UK CBAM, which starts on 1 January 2027, is a separate question with its own record.
