CBAM's Definitive Regime: What EU Buyers Now Ask Indian Suppliers

Three amendments from October 2025 (Regulation (EU) 2025/2083, the "Omnibus" simplification) set the regime's operating shape. A 50-tonne annual net-mass threshold (new Art. 2a with Annex VII) exempts importers whose covered imports stay under 50 tonnes across all CN codes in a calendar year — the Commission's estimate is that ~90% of importers fall out while ~99% of embedded emissions remain covered. The annual compliance date moved: the CBAM declaration and certificate surrender are due by 30 September, first in 2027 for calendar-2026 imports (Arts. 6(1), 22(1) as amended). And declarants gained a free election between actual embedded emissions — which require verification by an accredited verifier (IR (EU) 2025/2546) — and default values per Implementing Regulation (EU) 2025/2621, usable without any verifier.

The money in 2026 is real but small by design: certificates are surrendered only for the share of emissions not covered by the EU ETS free-allocation adjustment, and the CBAM factor is 97.5% in 2026 (Directive 2003/87/EC, Art. 10a(1a)) — so roughly 2.5% of embedded emissions are priced this year, rising on a fixed schedule to full pricing by 2034. Certificate sales open on the common central platform on 1 February 2027; for 2026 the certificate price is computed as a quarterly average of ETS closing prices, the first having been published on 7 April 2026.

Annex I coverage is broader than mill products and reaches finished articles Indian component makers actually ship. The iron and steel section covers Chapter 72 as a whole (except listed ferro-alloys and scrap) and, in Chapter 73, headings 7301–7311 plus — decisively — 7318 (screws, bolts, nuts, washers and similar fasteners) and 7326 (other articles of iron or steel). The aluminium section runs 7601–7614 plus 7616 (other articles of aluminium). Two adjacent headings are not covered today: 7320 (springs) and 7325 (other cast articles) — and components classified in Chapters 84, 85 and 87 sit outside CBAM entirely for now. That boundary is under active revision: the Commission's proposal of 17 December 2025 (COM(2025) 989) would extend CBAM to downstream goods with anti-circumvention rules, and the Council agreed its position on 12 June 2026 — a proposal, not yet law, but the direction of travel for precisely the components currently outside.

The classification stakes compound the coverage stakes: whether a fastener enters as 7318 or a machined part as 8708 is now also a CBAM boundary question on the EU side — one more regime in which HS drift across documents changes the money.

The definitive regime's data chain runs from the EU declarant to the Indian installation. For actual-values declarations, the Indian producer supplies installation-level embedded-emissions data computed under Implementing Regulation (EU) 2025/2547, verified by an accredited verifier; the producer can register directly in the CBAM registry as a third-country operator (Art. 10) so its installation data is reusable across EU customers. Where the producer supplies nothing, the buyer falls back to default values — lawful, verifier-free, but generally conservative, which makes a supplier who can evidence lower-than-default emissions cheaper to import from than one who cannot. Supplier emissions data is becoming a line item in EU purchasing, alongside price and lead time.

This is the pattern worth naming beyond CBAM: EU compliance obligations placed on importers convert into evidence demands cascading down the supply chain to Indian producers — the same structure as the EU Battery Regulation's calendar for HS 8507.60, and the demand-side visibility problem SectorWatch is designed to serve at firm and sector level. At shipment level, the emissions file, the CN-code determination and the 50-tonne arithmetic are documents and dates — the kind of dated, cited record TradeWatch's evidence packets are built to carry.
