CBAM Scope Expansion: Parliament Votes to Widen the Mechanism to 457 Products
On 15 September 2026, the European Parliament adopted its negotiating position on CBAM scope expansion, the biggest test yet of how far the EU's carbon border tax reaches into manufactured goods. The vote answers a competitiveness gap industry groups have flagged for months: a carbon cost applies when steel or aluminium crosses the EU border as a raw material, but not when the same metal arrives already built into a finished product such as a washing machine or a car part. MEPs used this week's plenary in Strasbourg to close that gap, alongside tighter anti-circumvention rules and a position on the Temporary Decarbonisation Fund for EU exporters. How far that gap closes, and how fast, is what the rest of this vote decides.
What MEPs Just Voted For
Parliament's plenary voted on 15 September 2026 to back its first-reading position: extend CBAM into steel- and aluminium-intensive downstream products, tighten anti-circumvention rules, and endorse a Temporary Decarbonisation Fund for EU exporters. None of it is finished law yet.
CBAM has applied full financial obligations since 1 January 2026 across iron and steel, aluminium, cement, fertilisers, electricity, and hydrogen (see carbmee's CBAM quick guide for the fundamentals). The vote extends that reach into manufactured goods, closing a gap the Council itself has flagged: producers outside the EU could turn steel and aluminium into finished goods before export, sidestepping a cost that today applies only to the raw material.
The CBAM Scope Expansion Fight: 180, 200, or 457 Products?
The European Commission's original December 2025 proposal added 180 downstream products to CBAM, effective 1 January 2028. These products average 79% steel or aluminium content and include machinery, vehicle components, and domestic appliances. The Council's June 2026 position widened that list to roughly 200 items.
Parliament's Environment Committee went further still. Citing a European Parliamentary Research Service briefing, its position covers 457 products, adding items such as fasteners, wire, springs, and household articles. ACEA, the European automotive association, has warned that complex automotive parts, sourced across dozens of sub-suppliers, will be costly to map accurately. EUROFER, the European steel association, has backed the wider list, arguing foreign producers currently dodge CBAM costs by processing steel into finished goods before export.
Parliament's position also defines "resource shuffling," a practice that disguises a product's true carbon origin, and closes a loophole that let goods sold through online platforms avoid CBAM obligations. Pre-consumer steel and aluminium scrap enters the mechanism too.
What Changes for Manufacturers and Importers
If Parliament's 457-product list survives trilogue, importers of steel- and aluminium-intensive finished goods will need supplier-level embedded-emissions data for hundreds of new product codes, not just raw materials. Compliance teams that currently track CBAM only for upstream steel and aluminium purchases will need to extend that tracking down the supply chain.
ZF, the automotive technology group, already submits over 40 CBAM reports a year across 35-plus EU legal entities and projects roughly EUR 8 million in CBAM costs by 2034 under the current scope alone. A wider product list only raises that exposure. The same supplier-engagement work that makes upstream CBAM reporting workable, collecting real supplier data instead of default values, becomes the template for whichever downstream list trilogue agrees. Manufacturers already running on primary emissions data instead of defaults can extend that system to new codes; those still on manual questionnaires will need to rebuild the process at scale.
What Happens Next
Parliament's vote opens trilogue: negotiations between Parliament, the Council, and the Commission to agree a single text. The product list is the central sticking point, since the two positions differ by more than 250 items. The institutions are aiming for a final text by the end of 2026, though that depends on how smoothly the ordinary legislative procedure runs from here.
If agreed, the expanded scope takes effect from 1 January 2028, the date in the Commission's original proposal. The linked Temporary Decarbonisation Fund, financed partly from CBAM certificate revenue, has its own timing gap: the Commission proposed distributing support in 2028 and 2029, while Parliament wants it starting in 2027 and open to downstream manufacturers and fertiliser producers too.
Outlook: Preparing for the CBAM Scope Expansion Before 2028
Two years sounds like room to spare, but building supplier data pipelines for a new product category takes time. Manufacturers importing steel- or aluminium-heavy goods, especially in automotive, machinery, appliances, and construction, are the most exposed regardless of where the final count lands between 200 and 457.
The safer approach is not to wait for the exact list. It is to build a carbmee EIS™-style data foundation now, one that captures embedded emissions at the transaction level rather than the product-category level, so extending coverage to new codes becomes a configuration change, not a new project. Watch three things: the trilogue product list, the Fund's start date, and Commission guidance on how scrap emissions get calculated.
The Bottom Line
Parliament's 15 September vote does not change any manufacturer's CBAM obligations today. It sets Parliament's opening position for trilogue, where the final number of downstream products, somewhere between 200 and 457, gets negotiated. Three things matter now: the effective date is provisionally 1 January 2028, the product list is still moving, and the operational challenge, supplier-level emissions data for finished goods, is the same regardless of the final count.
Manufacturers with steel or aluminium in their bill of materials should treat this as the signal to check exposure now, not once trilogue concludes. Run a CBAM exposure check to see which of your imported products could fall inside the expanded scope.
