CBAM guides for exporters

Short, plain-language answers for steel and aluminium exporters selling to the EU.

• What is CBAM? A plain-language explainer and glossary

  The EU Carbon Border Adjustment Mechanism in five minutes: what it charges, who pays, how the cost is worked out, and 37 terms exporters meet, each linked to a free tool.

• CBAM for Indian steel and aluminium exporters

  What the EU's carbon border charge means for you since January 2026: who pays, what counts, and why your buyer is asking for emissions data.

• Default values or actual emissions: which costs your buyer less

  How the EU default with its mark-up compares with your own verified figure, with a worked example, and when verifying is worth the cost.

• What your EU buyer will ask for under CBAM

  The emissions data, documents and verification EU importers request from non-EU suppliers, and how to prepare before the first declaration in 2027.

• CBAM timeline 2026 to 2034: deadlines, mark-ups and free allocation

  Every date that matters for exporters, and why the CBAM cost per tonne roughly doubles between 2026 and 2034 even if the carbon price stays the same.

• Who pays CBAM? Three common ways buyers and suppliers split the cost

  By law the EU importer pays for CBAM, but the cost lands in your price talks. Three common arrangements, what each means for your margin, and what to agree in writing.

• CBAM verifiers: who can verify, where to find one and what they check

  Your buyer can use your actual emissions only after an accredited verifier has checked them. Who may verify, where the official list is, what they look at and how to prepare.

• UK CBAM from 2027: what exporters to Britain need to know

  The UK starts its own carbon border tax on 1 January 2027. Who pays, the £50,000 threshold, the first deadlines, and how it differs from the EU CBAM.

• Register your plant in the EU CBAM Registry (O3CI): step by step

  Producers outside the EU can upload their plant and emissions data once and share it with their EU buyers. The three registration steps, the documents, and the company number to use for your country.

• CBAM anti-circumvention: what counts as dodging, and what does not

  The CBAM rules name two ways of dodging the charge: slightly changing goods to move them to a code outside the list, and splitting imports to stay under 50 tonnes. What that means for exporters.

• Carbon price paid at home: can it reduce your buyer's CBAM cost?

  If your plant pays a carbon price in its own country, your EU buyer may claim fewer CBAM certificates. How the rule works, what evidence is needed, and why the details are still pending.

• CBAM for fastener and wire makers: what counts, and why your yield matters

  Make screws, bolts, nuts or wire from bought steel? Which of your processes count for CBAM, how the steel you buy is counted, and why less scrap lowers your figure. From the Commission's iron and steel guidance.
