2KHSO5·KHSO4·K2SO4, commercially known as Oxone, is a white powder used for oxidation in pool sanitation and organic synthesis. Despite containing regular sulfate, primary classification under HTS 2833.40.60.50 as potassium peroxosulfate (monopersulfate) 'other' due to dominant peroxoacid salt component. Chemically defined per Chapter 28 notes.

Import Tips
• Submit compositional analysis showing 2KHSO5 as active ingredient to justify peroxosulfate heading over mixed salts
• Classify EPA pesticide registration if for antimicrobial pool use; provide end-use statement
• Avoid 2833.27 (aluminum potassium sulfate) confusion; specify monopersulfate structure
