Practical consequence for UK importers exporting steel or cement into the EU: If a UK company imports steel from Turkey and then re-exports finished products containing that steel into France, Germany or any other EU member state, the EU CBAM may be triggered at the point of EU customs entry — even if the UK company is not the customs declarant in the EU. The EU-based customs declarant (your EU customer or distribution subsidiary) must be an authorised CBAM declarant. UK businesses with EU subsidiaries or EU distribution should audit their supply chains immediately.

• Failure to surrender CBAM certificates: a penalty of between €50 and €150 per tonne CO₂e not covered by surrendered certificates. Member states must set the specific rate within this range. Several member states (Germany, France, Netherlands) have set rates at or near the maximum.
• Importing without authorised declarant status: prohibition on importing CBAM goods until authorisation is obtained, plus possible retroactive penalty for the period of unauthorised imports.
• Providing false or incomplete information: possible loss of authorised declarant status, plus financial penalties set by the member state (up to €50,000 in some jurisdictions).
• Failure to meet the 80% quarterly top-up obligation: corrective measures required within one month, plus potential fine at member state discretion.

Do I need a CBAM verifier for my steel imports?

Not always — but for most commercial-scale imports, yes. Commission Implementing Regulation EU 2023/1773 sets thresholds above which third-party verification by an EU-accredited CBAM verifier is mandatory. For steel, the threshold is set by the level of embedded emissions: if the embedded emissions declared for a single installation exceed a certain threshold per year, verification is required. Importers using Commission default values rather than actual installation data are generally exempt from the third-party verification requirement. However, using default values typically results in a higher CBAM liability, since defaults are set conservatively above actual best-in-class production.

How do I determine the country of origin for CBAM purposes when steel passes through multiple countries?

CBAM uses the EU Customs Code definition of origin — the country where the steel underwent the last substantial transformation. For steel, this is typically the country where the iron ore was reduced to iron and the steel was produced (the country of the steelworks), not the country from which the goods were directly shipped. Transit through a third country does not change origin. However, significant processing (e.g., hot-rolling, cold-rolling) in a third country after initial steel production may constitute a new substantial transformation, changing the country of origin.

Does CBAM apply to steel products downstream of raw steel — like tubes, wire, or fasteners?

It depends on the specific CN code. Annex I of the CBAM Regulation lists the covered goods. For steel, Annex I covers pig iron (HS 7201), ferro-alloys (7202), iron and steel products (7206–7207), flat-rolled products (7208–7212), bars and rods (7213–7216), wire (7217), angles and sections (7216), tubes and pipes (7304–7306), and certain downstream goods in Annex II. More refined downstream goods (e.g. screws, bolts, stampings) are NOT currently in scope. The Commission has committed to reviewing the scope by 2026 with a view to expanding to additional downstream goods from 2028.

Can Chinese cement imports generate a CBAM carbon price offset?

Almost certainly not, at present. China operates an ETS, but as of 2026 it covers only the power generation sector, not cement or steel production. For the carbon price offset under article 9 of the CBAM Regulation, the relevant carbon price must be applied specifically to the production of the imported goods in the country of origin. Since Chinese cement production is not subject to an explicit carbon price, no offset applies, and importers must surrender CBAM certificates for the full embedded emissions of Chinese cement. This is a major competitive implication for Chinese cement importers into the EU.

What happens if I import steel from a country with a recognised carbon price (e.g. UK ETS)?

The UK ETS is one of the carbon pricing schemes recognised for CBAM offset purposes. If you import steel from a UK steelworks that is covered by the UK ETS and has paid an explicit carbon price on its steel production, you may claim an offset equal to the carbon price paid (converted to €/tCO₂e at the applicable exchange rate). The offset must be documented: you need an attestation from the UK steelworks (or its UK ETS registry records) confirming the carbon price paid, plus confirmation from your CBAM verifier. The net CBAM liability is reduced accordingly. This can represent a significant saving for UK steel exporters to the EU.

Is blended cement (Portland-pozzolana, Portland-fly ash) subject to CBAM?

Yes, blended cements covered by CN 2523 are within CBAM scope. The challenge for blended cements is calculating embedded emissions accurately: only the clinker fraction generates calcination CO₂ emissions, while pozzolanic additions (fly ash, slag, natural pozzolana) are generally considered to have zero or very low embedded emissions. The declarant must identify the clinker content (as a fraction of total cement) and apply the embedded emissions only to the clinker portion. This typically results in a lower CBAM liability for blended cements (e.g., CEM II, CEM III) compared to ordinary Portland cement (CEM I), which can be 90–95% clinker.

How should a mid-sized importer with no existing ETS expertise build CBAM compliance capacity?

Start with three immediate actions. First, confirm or obtain authorised CBAM declarant status from your national competent authority — you cannot import CBAM goods without it. Second, map your supply chain: for each supplier installation, establish whether you will use actual emission data (which requires cooperation from the foreign installation) or Commission default values. Third, engage a CBAM-accredited verifier early — they can advise on data collection requirements, review your methodology and flag any grey-area classification issues (mixed-origin scrap, blended products, downstream goods classification). Finally, build CBAM costs into your import pricing models — at €62/tonne EUA, CBAM adds material cost to most non-EU steel and cement.
