HS 2522.10Metals

HS Code for Quicklime (HS 2522.10)

Calcined limestone - CaO - used as steel flux (basic slag chemistry), water treatment, sugar refining, and construction. Freight-sensitive due to low FOB value (~USD 60-120/t) and hydration risk in transit. CBAM Annex I; embedded CO2 is process-inherent (~0.75 tCO2/t from calcination alone).

Frequently asked questions

Why is CBAM tough on quicklime?

Calcination inherently releases 0.75 t of process CO2 per t of CaO (from CaCO3 -> CaO + CO2), plus 0.2-0.3 t from kiln fuel. Total ~1.0 tCO2/t means CBAM 2026 adds ~USD 85/MT - roughly 100% of FOB. Only very short-haul cross-border trade will survive.
