How does the CBAM 50-tonne threshold work?

Use one importer and one calendar year

The Dutch CBAM authority explains that the exemption applies where annual imports of the relevant goods do not exceed 50 tonnes. Crossing the threshold brings the full year’s relevant imports into the obligation, rather than only the amount above it.

Before calculating, establish which goods belong in the scope and which entity is the importer. A neat spreadsheet total is not a substitute for that review.

Illustrative example: combine the relevant goods

Assume one importer brings in 25 tonnes of covered steel and 30 tonnes of covered aluminium in the same calendar year, with no applicable origin exemption. The combined mass is 55 tonnes. Checking each line against a separate 50-tonne allowance would miss the combined threshold.

Do not add cumulative snapshots together

Imagine a profile contains a June year-to-date snapshot of 30 tonnes and a September snapshot of 40 tonnes. The September value already includes the earlier imports. Adding the two produces 70 tonnes and double-counts the earlier quantity.

Atmovo uses the latest dated cumulative snapshot within the selected year. Separate shipment or period quantities can be summed when their periods do not overlap. Mixing the two bases, falling cumulative values or conflicting snapshots requires clarification.

Avoid these calculation mistakes

The electricity and hydrogen exception means a below-threshold mass example cannot be used to infer their treatment. The current Atmovo pilot leaves their rules as insufficiently defined.

• Keep different importers and calendar years separate.
• Do not convert an undocumented or unverified quantity into a confirmed fact.
• Do not count out-of-scope goods just because they contain a covered material.
• Keep the end date of a snapshot visible; a recorded total is not a live customs feed.

What to do before running the check

Reconcile the quantity records to the importing entity, resolve classification and origin questions, then record the review. Atmovo can show the criteria and stored facts used in the pilot assessment. It does not replace the competent authority, file a declaration or certify an exemption.
