CBAM’s 50-tonne threshold: a model for small traders

The EU’s CBAM simplification uses an annual mass threshold that removes most importers from the mechanism while keeping nearly all covered emissions in scope. Reseated’s Trade Council sees a useful principle for future trade rules: match compliance demands to scale, and make costs understandable before small firms commit to a shipment.

What happened

On 5 September 2025, the European Parliament announced adoption of simplifications to the EU Carbon Border Adjustment Mechanism, including a 50-tonne annual mass threshold that took effect on 1 January 2026.

The European Parliament said the 50-tonne annual mass threshold would remove around 90% of importers from CBAM, most of them small and medium-sized businesses.
The simplification is expected to keep around 99% of emissions within the mechanism’s scope.
The threshold took effect on 1 January 2026.

What it means for small businesses

For a small trader, a clear scale-based threshold can determine whether a new compliance regime applies at all, rather than requiring every firm to bear the same administrative burden.

The CBAM case suggests that policymakers can reduce the number of firms facing obligations while retaining most of a measure’s intended emissions coverage.

Owners trading across borders still need plain-language rules and clear information about costs; a threshold alone does not tell a business what a particular shipment will cost.
