Key takeaway
What This Development Means
The European Commission found that CBAM's 50-tonne threshold exempts 0.87% of embedded emissions, below the statutory 1% ceiling. It announced no delegated amendment, so the existing threshold remains in force.
Has The Commission Changed The CBAM 50-Tonne Threshold?
No. The Commission found that the current threshold exempts 0.87% of embedded emissions, below the statutory 1% ceiling, and announced no delegated amendment. The 50-tonne cumulative net-mass threshold therefore remains the binding figure for the four sectors covered by the mass-based exemption.
Do Electricity And Hydrogen Importers Benefit From The 50-Tonne Exemption?
No. Electricity and hydrogen are excluded from the single mass-based exemption. The threshold applies to cumulative imports of cement, aluminium, fertilisers, iron and steel. Electricity and hydrogen importers must assess CBAM authorisation, reporting and certificate duties without relying on a mass allowance.
Source basis: European Commission, CBAM De Minimis Threshold Assessment (30 September 2026)
The European Commission has found that the Carbon Border Adjustment Mechanism (CBAM) 50-tonne threshold exempts 0.87% of embedded emissions, below the 1% ceiling set by the legislation. The assessment published on 30 September 2026 covers the period from 1 April 2025 to 31 March 2026.
CBAM 50-Tonne Threshold Passes The First Emissions Test
Article 2a(3) of the CBAM Regulation requires the Commission to test whether the single mass-based threshold excludes no more than 1% of embedded emissions in the relevant imported goods and processed products. The finding confirms that the current threshold remains within that environmental safeguard.
It does not introduce a new exemption or reset importer calculations. Regulation (EU) 2025/2083 already sets the threshold at 50 tonnes of cumulative net mass per importer and calendar year.
Scope Remains Limited To Four CBAM Sectors
The mass-based method covers aluminium, cement, fertilisers and iron and steel. The threshold aggregates covered net mass across those sectors for each importer rather than applying a separate 50-tonne allowance to every product code or shipment.
Electricity and hydrogen are outside the mass-based exemption. Importers of those goods remain within CBAM regardless of imported mass, subject to the Regulation's other scope rules. The assessment does not alter product codes, embedded-emissions methods, authorised declarant requirements or certificate obligations.
Under Annex VII, the methodology identifies a threshold that captures at least 99% of emissions and adds a 0.25 percentage-point uncertainty margin. Article 2a requires a delegated amendment where the calculated threshold deviates from the applicable threshold by more than 15 tonnes. The Commission's notice reports the 0.87% result but announces no delegated act, so 50 tonnes remains the binding figure.
What Applies Now And Later
The definitive CBAM regime has applied since 1 January 2026. Importers above the threshold for the four mass-based sectors need the appropriate authorised declarant status or application reference. They must collect quantity, production-route and embedded-emissions evidence for 2026 imports now.
By 30 September 2027, authorised declarants must submit the first annual declaration for 2026 and surrender the corresponding certificates. Where actual rather than default values are used, non-EU installations and accredited verifiers need a defensible evidence chain. Foresight's definitive-period guidance analysis explains why that operational work cannot reliably be reconstructed after year end.
The assessment supports regulatory stability without reducing compliance risk. Importers close to 50 tonnes still need cumulative controls because a late shipment can remove the exemption for the whole calendar-year position.
Businesses should reconcile 2026 cumulative net mass by importer across all four covered sectors and set an escalation trigger before the 50-tonne boundary is reached.
Summary
The Commission's first published assessment keeps the CBAM threshold within its statutory emissions cap and announces no change to the 50-tonne figure. Importers should continue cumulative mass controls and prepare 2026 emissions evidence for the first declaration and certificate surrender deadline in September 2027.
