Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

3824Lower: 15% vs 38.1%

If coated or with anti-caking agents for retail

Additivated forms for retail sale classify as mixtures in 3824 per Chapter exclusions.

2840.19.00.00Lower: 35.1% vs 38.1%

If borate-stabilized variant

Peroxoborates have separate classification; true persulfates remain in 2833.

2905.49Lower: 15.5% vs 38.1%

If organic derivative misclassified

Organic peroxides go to Chapter 29; Chapter 28 covers only inorganic chemically defined compounds.
