The second round of trilogue negotiations on extending the EU Carbon Border Adjustment Mechanism (CBAM) to downstream steel products is provisionally scheduled for 30 November 2026, and negotiators are still aiming for a political deal before the end of the year. For fastener manufacturers and exporters, the window to prepare has effectively narrowed to weeks.

On 17 December 2025, the European Commission proposed extending CBAM to roughly 180 downstream product categories from 2028 — the vast majority of them steel- and aluminium-intensive goods. Screws, bolts, nuts, washers and wire sit squarely inside the proposed lists. The logic is simple: today, a non-EU manufacturer can take CBAM-covered steel, turn it into a finished fastener, and ship it into the EU without triggering any carbon charge. The downstream extension is designed to close exactly that gap.

The first political trilogue on 20 October 2026 produced agreement on the electricity provisions but left the remaining questions — including the detailed scope lists and emissions-calculation rules — to this second round. Industry is split: twenty European steel and downstream associations have pushed for the broadest possible extension, while manufacturers with complex multi-country supply chains warn that tracing embedded emissions through finished components is far harder than the Commission assumes.

Two points deserve attention right now:

1. Fasters are outside today's CBAM but not outside the debate. Heading 7318 — where hex bolts, stud bolts, nuts and washers are classified — does not appear in the current Annex I. But the regulation's Article 12(2) requires the Commission to assess by 30 June 2027 whether goods "containing a significant amount of steel" should be brought into scope. Fasteners are a textbook case, and a political deal in December would all but guarantee their inclusion in the 2028 definitive phase.

1. The paperwork starts at the mill, not the border. Even under the current regime, EU importers are asking suppliers for verified installation-level emissions data rather than accepting default values — because actual data determines the size of the certificate bill when CBAM moves from reporting to payment in 2027. Default values are set deliberately high, so importers who cannot obtain real data from their suppliers will simply price that risk into their buying decisions.

• Map the data chain. Identify which mills supply the wire rod and bar stock behind each fastener grade, and whether those mills can issue verified per-product or per-installation emissions data.

• Test the gap. Run a quotation both ways — with default values and with actual data — to understand how the difference could affect landed-cost competitiveness against suppliers who can produce a clean data set.

• Budget for certificates. Importers buying fasteners directly should check 2026 volumes against the 50-tonne de minimis threshold and obtain authorized declarant status before certificate sales open in February 2027.

• Watch 30 November and 30 June. The 30 November trilogue will show whether the December deal is realistic; the Article 12(2) assessment due by 30 June 2027 will show whether fasteners are named explicitly in the Commission's legislative proposal.

The direction of EU trade policy is unambiguous: more origin granularity, more emissions granularity, and more upstream documentation. Suppliers who treat emissions data as a commercial asset — not a compliance chore — will be the ones still holding their EU accounts when the downstream extension takes effect.
