Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If primarily ammonium persulfate with minor potassium
Ammonium peroxosulfates classify separately under 2833.40.20; potassium-dominant goes to 2833.40.60.
If classified as complex salts of inorganic bases
Chapter note specifies double salts may go to 2842 if not fitting specific peroxosulfate headings.
If for industrial mixtures sold as initiator blends
Blends with fillers or for specific uses classify as preparations in 3824, not pure compounds.

Import Tips & Compliance
• Provide assay reports proving potassium content and peroxo structure; label as double salt to avoid ammonium-only classification
• Watch for moisture content affecting stability during shipping
