TL;DR
- ▸CBAM certificates apply from January 2026 to covered non-EU steel imports above the applicable thresholds; the cost tracks the EU ETS carbon price.
- ▸Q3 2026 certificate price: EUR 82.32/tCO2, published on 5 October 2026. Use the price for the quarter in which the goods were imported.
- ▸The payable amount needs emissions data, the free-allocation adjustment and eligible carbon-price deductions. It is not a flat 2.5% of gross emissions in 2026.
- ▸Buyers should verify product classification, origin and embedded-emissions documentation per project - EU-sourced steel may reduce or avoid import exposure, but nobody is exempt from checking.
What is CBAM?
The Carbon Border Adjustment Mechanism (CBAM) — EU Regulation 2023/956, as amended — addresses carbon leakage through obligations for covered imports. The assessment depends on the goods, origin, emissions and applicable adjustments, not simply on a supplier being outside the EU.
For procurement engineers sourcing structural steel, this can translate into a measurable import cost and documentation burden for covered non-EU steel from January 2026 onward.
CBAM Implementation Timeline
How Much Does CBAM Cost?
The Commission published the Q3 2026 certificate price of €82.32/tCO₂ on 5 October 2026. The table multiplies that price by illustrative emissions factors, before free-allocation adjustment or carbon-price deductions. These are not country defaults, payable 2026 charges or 2034 price forecasts.
European Commission: CBAM: Q3 2026 · Adjustment rules: (EU) 2025/2620
| Scenario | Assumed CO₂ | Gross value | Basis |
|---|---|---|---|
| Non-EU example A | 2.1 tCO₂/t | €172.87/t | ILLUSTRATIVE |
| Non-EU example B | 1.9 tCO₂/t | €156.41/t | ILLUSTRATIVE |

CBAM Import Exposure Calculator
Gross emissions-value scenario for steel imports, using the Q3 2026 certificate price of €82.32/tCO₂ (published 5 October 2026).
Gross scenario, before adjustments
Tonnage × 1.691 tCO₂/t × €82.32/tCO₂. The emissions factor is an illustration, not a verified supplier value or a legal default for CN 7308. Holding this price constant gives a 2034 full-exposure scenario, not a future-price forecast.
Steel-Hub EU-Origin Scenario
EU-origin sourcing can reduce CBAM import exposure. Verify origin, CN classification, embedded-emissions data, and project-specific documents before award.
Not the payable CBAM amount or tax advice. Actual liability depends on scope, annual import thresholds, emissions, benchmark-based free-allocation adjustment and eligible carbon-price deductions. It is not simply 2.5% of gross emissions in 2026. Use the price for the import quarter; purchases for 2026 imports begin in February 2027.
Why EU-Sourced Steel Wins
Steel manufactured within the EU is already inside the EU carbon-pricing framework rather than treated as a CBAM import. This can reduce CBAM exposure for buyers compared with covered non-EU imports, provided origin, CN classification, and project documentation are verified.
Key Takeaways
- ✓CBAM certificates apply from January 2026 to covered non-EU steel imports above applicable thresholds.
- ✓Certificate prices vary by import quarter in 2026; the Q3 price is not a Q4 quote or a future-price forecast.
- ✓EU-manufactured steel can reduce CBAM import exposure, but origin and classification must be verified.
- ✓Nearshoring to Croatia can reduce customs, documentation, and long-lead-time risk.
- ✓Request EN 10204 3.1 traceability and current project-specific compliance documents with every delivery.
CBAM procurement FAQ
When does CBAM start costing money?
The definitive regime covers eligible imports from 1 January 2026. Certificate purchases for those imports begin in February 2027, not January 2026. Importers need to assess scope, exemptions and documentation before importing.
How much does CBAM add per tonne of steel?
There is no universal charge per tonne. At an illustrative 2.1 tCO2/t and the Q3 2026 price of EUR 82.32/tCO2, gross emissions value is EUR 172.87/t before adjustments. This is not the payable amount: free-allocation benchmarks and eligible carbon-price deductions must be applied. Nor is it a forecast for 2034.
Does buying EU steel remove CBAM exposure?
Steel produced inside the EU is not a CBAM import, so the mechanism does not apply to it. That is not the same as a blanket exemption for the buyer: classification, origin and documentation still have to be verified per project, and non-EU material anywhere in the supply chain can bring obligations back.
Which steel products are covered?
CBAM covers listed CN codes for iron and steel, including fabricated structures under CN 7308 - the category that contains halls, towers and structural steelwork. Because coverage is defined by CN code rather than by product name, the customs classification of what you actually import decides whether it is in scope.
