Last updated: July 2026 dataChromium trioxide (CrO₃), the anhydride of chromic acid, is a hexavalent chromium compound used primarily in hard chrome electroplating, metal surface treatment, and as an oxidizing agent in specialty chemical synthesis. Kazakhstan and India are the leading US suppliers, with South Africa also a significant source — all three countries have substantial chromite ore and ferrochrome processing capacity that underpins their chromium chemical exports. Importers should be aware that hexavalent chromium compounds face stringent occupational health and environmental regulations under EPA and OSHA frameworks, and proper hazmat documentation is required at entry.

Chromium trioxide is classified as a hazardous material under DOT regulations and as a toxic substance under TSCA. Importers must provide a Safety Data Sheet (SDS), proper UN hazmat labeling (UN 1463), and ensure the shipment complies with EPA TSCA import certification requirements. Carriers and freight forwarders must also be notified of the hazardous nature of the cargo.
Chromium trioxide (CrO₃) is a hexavalent chromium compound and a strong oxidizer, distinct from the trivalent chromium sesquioxide (Cr₂O₃) and other lower-valence chromium oxides covered by 281990. The valence state is commercially critical: trivalent chromium compounds are far less toxic and are used in pigments and refractory applications, while hexavalent CrO₃ is restricted or regulated in many jurisdictions due to its carcinogenicity.
