Products classified under HTS 2833.40.60.10
Potassium Persulfate Crystals
Potassium persulfate (K2S2O8) is a white crystalline powder used as an oxidizing agent in chemical synthesis and polymerization processes. It falls under HTS 2833.40.60.10 as a peroxosulfate (persulfate) of potassium, specifically classified as 'other' peroxosulfates of potassium. This chemically defined inorganic compound meets Chapter 28 criteria for peroxosulfates.
Diammonium Potassium Persulfate
A double salt combining potassium persulfate with ammonium, used in etching and polymerization applications. Classified under HTS 2833.40.60.10 as a peroxosulfate of potassium per Chapter 28 note on double salts in 2842, but specifically as 'other' potassium peroxosulfates here.
Technical Grade Potassium Persulfate Powder
Technical grade K2S2O8 powder for industrial bleaching and initiator use, with >98% purity. It is a peroxosulfate of potassium, fitting HTS 2833.40.60.10 as 'other' peroxosulfates, chemically defined per Chapter 28.
