CBAM Deadlines & Obligation Tracker
Every CBAM date that matters — certificate prices, quarterly holding checkpoints, the first annual declaration, and the regulatory milestones that reshape scope. Filter to your sectors and export the lot to your calendar.
Why a CBAM Deadline Tracker Matters
CBAM is not a single filing — it is a rolling set of obligations spread across the year, each with its own date. Miss the 50% quarterly holding checkpoint and you can be forced to buy certificates at a worse price; miss the annual declaration and you face penalties. The dates also move as the regulation evolves, so a static checklist goes stale fast.
This tracker keeps the full CBAM timeline in one place and lets you filter it to the sectors you actually import, so you only see what applies to you. Save your sectors and the tool remembers them; export the filtered list to Outlook, Google Calendar or Apple Calendar with one click.
Frequently Asked Questions
What are the key CBAM deadlines for importers?
The critical dates are: the CBAM definitive period start (1 January 2026, 2.5% factor); quarterly certificate price publications through 2026; certificate sales opening on 1 February 2027; the factor rising to 5% on 1 January 2027; the 50% quarterly holding checkpoints from 2027; and the first annual CBAM declaration due 30 September 2027 covering all 2026 imports.
When is the first CBAM declaration due?
The first annual CBAM declaration is due 30 September 2027 and covers all CBAM goods imported during calendar year 2026. Certificates must be surrendered at that point to cover the declared embedded emissions.
What is the CBAM 50% holding requirement?
From 2027, at the end of each quarter an importer must hold CBAM certificates covering at least 50% of the cumulative embedded emissions of its imports so far that year. This spreads the purchase obligation across the year rather than concentrating it at the annual surrender.
