2833.40.60.50/Sodium Persulfate Powder/China

Sodium Persulfate Powder from China

Sodium persulfate (Na2S2O8) is a white crystalline powder used as an oxidizing agent in chemical synthesis, polymer initiation, and bleaching processes. It falls under HTS 2833.40.60.50 as a peroxosulfate (persulfate) of sodium, classified as 'other' peroxosulfates not specified elsewhere in the subheading. This chemically defined inorganic compound meets Chapter 28 criteria for peroxosulfates.

Import Tips

• Verify purity certificate (typically 98%+ Na2S2O8) to confirm classification as chemically defined peroxosulfate under Chapter 28 Note 1

• Include Material Safety Data Sheet (MSDS) highlighting oxidizing properties for DOT hazardous material compliance during import

• Avoid misclassification as general sulfates (2833.2x) by providing assay reports; common pitfall is bulk packaging mistaken for industrial mixtures
