The Directorate General for Energy and Climate, responsible for implementing the EU Border Carbon Adjustment Mechanism (MACF) in France, is currently sending reminder letters to importers who have not filed their declarations. The deadline mentioned on these letters is generally two months. Missing this window means risking a financial penalty and, as of 2026, an outright ban on importing products covered by this regulation. Keewe can help you from A to Z to avoid penalties and save time.
The letter reporting a deviation from regulation (EU) 2023/956 (MACF regulation), which has been sent out since April 2025, is an official reminder that :
- all tasks relating to the transitional period (2023-2025) are to be carried out via the transitional MACF register,
- those relating to the effective period (from 2026) must now be processed in the MACF 2.0 (or "definitive") register, under EORI SIREN, and
- late importers have a short deadline to regularize their situation(douane.gouv.fr).
To put it plainly: if you have imported MACF goods since October 2023 without having filed your quarterly reports, the authorities are asking you to do so within 60 days.
You are if :
The transitional period runs from the end of 2023 to the end of 2025, and is designed to prepare all stakeholders (European importers, non-European suppliers, etc.) for the definitive implementation of the MACF from 2026. During this period, European companies covered by the MACF must report the carbon emissions of imported products on a quarterly basis via a dedicated online portal (the transitional MACF register).
From 2026 and the start of the effective MACF application period, MACF declarations will have to be filed on the definitive register (or MACF 2.0 register), as distinct from the transitional MACF register. In addition, it is via this definitive register that importers must, from March 2025, apply for "authorized MACF declarant" status, which is essential if they are to continue importing products from 2026 onwards.
