Last updated: August 2026 dataPotassium dichromate and related chromate salts are critical intermediates in leather tanning, metal surface treatment, and pigment manufacturing, but their hexavalent chromium content subjects them to stringent handling and environmental regulations in many jurisdictions. The US tariff schedule separates potassium dichromate (2841501000) from other chromates, dichromates, and peroxochromates (2841509100). Austria and China are the leading US import sources, with France and India also supplying the market.

While EPA does not administer a formal import permit for chromate salts, these compounds are regulated under TSCA and RCRA as hazardous substances. Importers must ensure compliance with TSCA reporting obligations and proper hazardous materials documentation (SDS, UN classification) at the port of entry.
Peroxochromates contain peroxo (O–O) linkages in addition to the chromate anion, giving them stronger oxidizing properties. Standard chromates and dichromates lack this peroxo group. Both types fall under 2841509100 unless the compound is specifically potassium dichromate, which has its own line at 2841501000.
