What the Draft CBAM Rules Actually Change for Importers
From 1 January 2026, CBAM moves into its definitive phase. Importers of covered goods will no longer deal only with transitional reporting. They will also need to manage registry access, authorisation status, and embedded emissions in a live compliance process.
That changes CBAM from a reporting task into regulatory procurement. Buyers must coordinate customs declarations, authorised CBAM declarant status, and planning for CBAM certificates. The Commission has also confirmed that the certificate price follows the average EU ETS auction price.
The 2025 simplification package added a material operational shift. It introduced a new de minimis threshold based on 50 tonnes of aggregate net mass per importer per calendar year. That changes which flows need to be monitored.
For B2B buyers in steel, aluminium, fertilisers, cement, electricity, and other CBAM sectors, the practical question is no longer whether to enter compliance. It is how to build a compliant buying flow that connects origin data, verification, and mid-year liabilities.
That is why the key policy question matters now. If the system allows deductions for carbon credits or carbon prices already paid abroad, the real issue becomes which instruments qualify and what proof is needed.
Which Carbon Credits Are Likely to Qualify and Which Will Not
The Commission’s 2025 call for evidence focused on the deduction of the carbon price paid in a third country. That is an important signal. The issue is not generic offsetting. It is proof of a carbon price actually borne in the foreign production chain.
In practice, the most likely qualifying instruments are those with a direct and verifiable link to the imported product. That points to carbon taxes, foreign ETSs, or equivalent pricing mechanisms. Voluntary carbon credits that are disconnected from the embedded emissions of the CBAM good look much less likely to qualify.
The EU ETS history points in the same direction. International credits were historically tightly limited and only allowed under very specific conditions. That makes it more likely that CBAM will favour carbon pricing instruments, not generic offset credits.
For global supply chains, exclusion risk is real. Credits without additionality, without public serialisation, or with registries that do not match CBAM evidence requirements are more vulnerable. Multi-country supply chains with sub-suppliers that are not aligned on data quality are especially exposed.
The real question is not just which credit to buy. It is which proof of payment and climate attribute can survive verification, audit, and customs control. That leads directly to the deduction cap and to procurement strategy.
How the Deduction Cap on International Credits Could Affect Procurement Strategy
If deductions are allowed only up to a cap, buying strategy changes fast. Operators would no longer hedge the full liability with foreign credits. They would need to cover the remaining exposure with CBAM certificates.
That pushes buyers toward a mixed portfolio. They may need supply contracts with embedded carbon price, eligible international credits where available, and a plan for the residual position in CBAM certificates. The certificate price discovery in 2026 is quarterly, so timing matters.
For procurement and sustainability teams, the key metric becomes net compliance cost per tonne. That includes the price of any eligible credit, any tax or equivalent price already paid in the third country, verification cost, and the cost of the remaining CBAM certificates.
In tight-margin sectors such as semi-finished steel or intermediate fertilisers, even a moderate cap can change sourcing decisions. Buyers may prefer suppliers with stronger MRV systems or countries with recognisable carbon pricing.
The main risk is no longer only financial. It is operational. Purchase timing, credit traceability, and registry proof become the bottlenecks that decide whether the deduction holds up in audit.
The Compliance Risk for Buyers: Timing, Documentation, and Registry Proof
From 2026, CBAM compliance depends on structured data in the definitive registry. Buyers need to link every deduction to coherent, serial, and verifiable documents. Simple commercial statements from suppliers will not be enough.
Timing risk is also important. With annual declarations and liability calculated during the import year, late credit purchases or an incomplete dossier can leave a company short of certificates.
B2B companies will need evidence on the origin of goods, production year, embedded emissions, carbon price paid in the third jurisdiction, and the match between the imported batch and the payment proof. Without that chain, a deduction can be rejected.
For multi-country importers, governance has to include registry proof, data quality policy, third-party verification, and control over indirect customs representatives. The CBAM authorisation framework spreads responsibility across several actors.
If this administrative friction grows, the market will split. Some buyers will seek highly documented compliant credits. Others will focus on reducing the cost of CBAM certificates alone.
What This Means for Carbon Credit Prices, Supply, and Market Segmentation in 2026
The most likely 2026 outcome is market segmentation. Credits or instruments with strong documentation, registry interoperability, and a direct link to carbon price paid should command a premium. Generic or weakly verifiable credits should trade at a discount.
The price anchor remains the CBAM certificate. The Commission will publish the quarterly price in 2026, based on the quarterly average clearing price of EU ETS auctions. That gives buyers, traders, and suppliers a clear reference point.
On the supply side, demand for CBAM-ready instruments may shift toward jurisdictions with comparable carbon pricing and toward projects or credits with strong traceability. Volumes that are not eligible may be pushed back into voluntary markets that are less connected to import compliance.
For operators and processors, this can create two different price layers. One is for physical compliance at the EU border. The other is for reputational or voluntary coverage. That will likely widen the gap between audit-grade credits and commodity credits.
The strategic conclusion for 2026 is simple. The advantage will not go to buyers who just find the cheapest credits. It will go to those who connect procurement, data governance, and carbon accounting into a CBAM-ready supply chain that can be documented end to end.
