Products classified under HTS 2841.50.91.00
Sodium Dichromate Dihydrate
Sodium dichromate dihydrate (Na2Cr2O7·2H2O) is a crystalline orange salt of a peroxometallic acid, specifically a dichromate of sodium. It falls under HTS 2841.50.91.00 as 'other' chromates, dichromates, and peroxochromates not specified elsewhere in the subheading. Primarily used in leather tanning, pigment production, and wood preservation.
Potassium Dichromate Crystals
Potassium dichromate (K2Cr2O7) in crystalline form is a strong oxidizer and salt of dichromic acid. Classified under HTS 2841.50.91.00 as an 'other' dichromate, distinct from basic chromates like chromic acid. Widely used in analytical chemistry, photography, and as a mordant in dyeing.
Ammonium Peroxochromate Powder
Ammonium peroxochromate is a peroxometallic salt containing the peroxodichromate anion, fitting Chapter 28 notes for ammonium salts of oxometallic acids. It is classified in HTS 2841.50.91.00 as 'other' peroxochromates. Applied in bleaching agents and specialized oxidation processes.
