# Commission proposes CBAM expansion to downstream products

Date: 2025

## Core record and legal stage
On 17 December 2025 the [European Commission](/organizations/european-commission) proposed amendments to extend the carbon border adjustment mechanism to selected downstream products and tighten anti-circumvention safeguards. The proposal recognised a potential weakness of covering steel and aluminium inputs while leaving some manufactured products that embody those inputs outside the regime. It was not enacted on announcement day; the Council and Parliament still had to negotiate. Treating proposal as binding law would misstate importers' actual legal obligations.

## Mechanism
For a firm manufacturing a component inside Europe, EU ETS costs may attach to the underlying metal. A competing finished product assembled overseas can contain imported high-carbon metal without the same direct CBAM exposure if it is not itself covered. This creates a possible incentive to move the last production step instead of lowering emissions. Expanding coverage might address that loophole but makes the product list harder to police. Customs codes, embedded material shares and calculation methodologies become decisive.

## Decision-makers, money and stakes
The Commission is the legislative initiator, while Council and Parliament control adoption. European manufacturers of covered downstream goods could benefit from more comparable carbon costs, whereas import-dependent assemblers may face higher input expenses and more complex documents. US, UK and Canadian exporters have an interest in knowing exactly which products enter scope. The proposal does not itself tell them to purchase certificates for every proposed good. Investment planning should account for likelihood and timing, without claiming legal certainty that does not yet exist.

## Strongest counter-view
The counterargument is that downstream expansion could multiply compliance complexity faster than it reduces carbon leakage. Supporters argue excluding finished products allows companies to evade the intention of carbon-price equivalence through geographic restructuring. The correct way to decide includes identifying actual substitution patterns and the volume of embedded metal in candidate products. The June 2026 Council position was a subsequent negotiation step rather than proof of final enactment.

## What to watch
The distinction between a customs duty and emissions accounting is particularly important for mixed-material goods. A finished appliance may contain steel and aluminium alongside electronics, plastic and labour value. Whether it should be covered depends on legislative thresholds, not on the simple fact that a metal appears somewhere inside. This December proposal begins a new product-definition debate separate from the 2023 founding law.

## Exposure for industrial buyers
A downstream extension could affect firms assembling machinery, industrial equipment and metal-containing components, but it cannot be modelled as a broad tax on every finished object. The product list, rules for attributing input emissions and permitted evidence are essential. For example, a European assembler competing with a foreign finished component producer may welcome scope expansion while another EU firm relying on imports may see additional costs. The proposal's distributional effects therefore cut across countries and industries. Analysts should treat the possibility of wider scope as a planning risk until adoption.

## The production-location problem behind the proposal
Suppose a European factory buys steel whose EU ETS-related carbon costs are partly reflected in the input price, while an overseas competitor buys steel, performs a final fabrication step and exports the completed article. If only the basic imported steel is in CBAM scope, the competing finished article may avoid the same direct border accounting. This is the policy risk the Commission sought to address, not proof that any named firm had already relocated to evade the law. The proposal targeted selected steel- and aluminium-intensive downstream goods rather than every object containing metal. Its design makes definitions of input shares, product categories and embedded emissions central to whether the measure is effective and enforceable.

## The proposed 2028 horizon is not the law of 2025
The Commission described an intended 1 January 2028 start for the additional downstream scope. That was a proposed commencement date contingent on legislative agreement, not a tax imposed in December 2025. A US machinery producer selling into the EU could prudently assess candidate customs codes and plant-level records without recording a definitive certificate liability under an unpassed amendment. In September 2026 Parliament adopted amendments for negotiations, further demonstrating that the legislative text was still contested. The meaningful watchpoint is a final adopted regulation with legally specified codes and effective dates; a political announcement or negotiation position cannot replace it.
