On June 12, 2026, the Council of the EU reached agreement to extend the Carbon Border Adjustment Mechanism (CBAM) to certain downstream products and to strengthen existing anti-circumvention measures. It follows the strengthening proposal submitted by the European Commission in December 2025, and the Commission welcomes the Council's rapid progress. For manufacturing supply chains, the direction is now clear: CBAM's boundary is set to extend beyond intermediate materials.
What Changes — Downstream Expansion of Scope
CBAM has so far targeted carbon-intensive basic materials such as steel, aluminum, cement, fertilizers, electricity, and hydrogen. This agreement includes a direction to extend scope to "certain downstream products." Businesses that process steel or aluminum intermediates and import them into Europe may newly become subject to CBAM reporting and cost burdens. Even without exporting the material itself, the impact widens significantly once products that incorporate it become covered.
Anti-Circumvention and Electricity Rule Review
The Commission's December 2025 proposal comprises four elements: (1) extending scope to downstream products, (2) strengthening anti-circumvention safeguards, (3) changing rules on electricity, and (4) technical adjustments. Strengthening anti-circumvention makes it harder to avoid CBAM by lightly processing covered goods via a third country, which can press the entire global supply chain using high-carbon materials to review sourcing. The electricity rule change directly affects cost estimates for electricity-intensive manufacturing sites that source power across borders.

Legislative Schedule and Preparation Window
The Council agreement is a milestone in the legislative process, not a final outcome. After the European Parliament reviews and formally adopts the proposal in plenary, the trilogue among Parliament, Council, and Commission begins in earnest. The Parliament's plenary adoption is expected in September 2026, and final legislation is anticipated no earlier than late 2026 to 2027. A Council agreement within roughly six months of the Commission proposal is unusually fast, signaling that the EU treats CBAM strengthening as a climate-policy priority.
Implications for Manufacturers and Procurement
Although pre-final, the direction toward downstream expansion is clear, and it is worth starting early to inventory whether your products and components could fall into future scope. Beyond existing reporting practice, downstream expansion makes scope determination itself a key issue. Given design and procurement lead times, regulations applying in 2026–2027 are effectively already in the preparation window. Rather than waiting for the final legislative form, establishing a system to collect suppliers' carbon-intensity data enables earlier estimation of cost impact and pricing decisions.
