# Are refractory bricks and castables covered by CBAM?

Canonical: https://senseible.earth/answers/are-refractories-covered-by-cbam

Refractory bricks and shapes under 6902 and 6903 are not covered. The catch is aluminous cement: calcium aluminate cement under 2523 30 is in Annex I, so a refractory maker exporting it as cement must supply embedded emissions.

## Covered and not covered

- Bricks, blocks and shapes: 6902 and 6903, not covered.
- Monolithic castables and mortars: usually 3816, not covered.
- Calcium aluminate cement sold as cement: 2523 30, covered, with indirect emissions counted.

## Could coverage change

The Commission proposed in December 2025 to extend CBAM to some downstream steel and aluminium products. As of October 2026 that is not law, so check Annex I again before each contract season.

Senseible reads your fuel and electricity invoices into dated, fingerprinted records, so if a buyer asks for a product footprint you can answer from documents rather than estimates.
