European Union carbon border adjustment mechanism reaches full phase-in for primary materials

Prior state
The CBAM transitional reporting period had been in force; full financial adjustment for cement, iron and steel, aluminum, fertilizers, electricity, and hydrogen remained scheduled for 2026–2034.
Material change
From the first half of 2028 the definitive CBAM regime applies financial charges to covered primary materials at the EU border, with free allocation phase-out under the Emissions Trading System accelerating in parallel.
Why now
The legal timeline fixed in the 2023 CBAM regulation places the start of the definitive period in 2026 with progressive expansion; by 2028 the first full year of charges on the core product groups is operational after administrative capacity and third-country reporting systems have been tested.
Mechanism and resistance
Importers must surrender certificates corresponding to embedded emissions. Resistance arises from trading partners seeking equivalence recognition, from energy-intensive EU manufacturers facing cost pass-through, and from administrative bottlenecks in verification.
Consequences
Import costs for covered materials rise differentially by origin. Downstream manufacturing in the EU experiences margin pressure; some non-EU producers accelerate domestic carbon pricing or seek bilateral equivalence deals. Trade diversion toward lower-carbon or exempt suppliers becomes measurable.
End state
CBAM charges are collected on the majority of covered primary-material imports, and free ETS allocation for the same sectors has declined by a material fraction relative to 2025 levels.
Observable test
European Commission or national customs data showing certificate surrender and revenue collection for the first full calendar year of the definitive regime covering at least the original six sectors.
Disconfirming sign
Legislative delay or suspension of the financial obligation beyond mid-2028.
