CBAM cost estimator for GCC exporters
The EU Carbon Border Adjustment Mechanism (CBAM) charges EU importers for the carbon in certain goods. Your EU buyer pays, but the cost lands in your price. This tool gives a rough annual estimate. It is not legal or tax advice.

At 50 tonnes or less a year, an EU importer may fall under the de minimis exemption. The threshold is cumulative per importer across all CBAM goods (excluding hydrogen and electricity), so your buyer's other imports count too.
How to read this. Certificates per tonne = embedded emissions minus (CBAM factor x EU benchmark). The benchmark is Column B of Implementing Regulation (EU) 2025/2620 for the default value's production route. The CBAM factor falls from 97.5% in 2026 to 0% in 2034. Because GCC default values sit well above EU benchmarks, most of the default value is charged even in 2026. Simplifications: one CN code per group, the benchmark is not adjusted for your own route if you use actual data, and the carbon price paid at origin is netted per tonne charged. Treat the result as an estimate, not a declaration.
Key rules and dates
- The definitive period started on 1 January 2026, after the 2023 to 2025 transitional reporting phase.
- Only authorised CBAM declarants may import CBAM goods above the threshold.
- The 2025 simplification (Regulation (EU) 2025/2083) replaced the old EUR 150 per consignment exemption with a 50 tonne per importer per year threshold. Cross it and the full year is in scope. Hydrogen and electricity are not covered by the threshold.
- Sale of CBAM certificates for 2026 imports starts on 1 February 2027. The first annual declaration and surrender for 2026 imports is due by 30 September 2027.
- Declarants must hold certificates covering at least 50% of embedded emissions at the end of each quarter from 2027.
- CBAM factor by import year: 2026 97.5%, 2027 95.0%, 2028 90.0%, 2029 77.5%, 2030 51.5%, 2031 39.0%, 2032 26.5%, 2033 14.0%, 2034 0.0%.
- Default values carry a mark-up: 10% in 2026, 20% in 2027 and 30% from 2028. Fertilisers carry 1% in every year. Where a GCC country has no value of its own for a good (for example hot-rolled steel), the "Other countries and territories" value applies.
- Indirect emissions (from electricity) count for cement and fertilisers. For iron and steel, aluminium and hydrogen, only direct emissions count.
