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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If solidified or stabilized with urea or organics
Stabilized persulfates with organic substances fall under heading 2831 or related stabilized forms in 2847 per Chapter 28 note.
If put up in retail packings with additives for specific end-use
Mixtures or preparations for retail sale, like polymerization initiators, may classify as chemical preparations in 3824 rather than pure compounds.
If simple sulfate without peroxo group
Non-peroxo sulfates of potassium go to 2833.19, as peroxosulfates are distinctly separated in 2833.40.
