Are refractory bricks and castables 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.
What Senseible does here
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.
