2833.40.60.50 - Other

This classification, HTS 2833.40.60.50, encompasses peroxosulfates (persulfates) that are not specifically enumerated under preceding subheadings. Peroxosulfates are chemical compounds characterized by the presence of the peroxodisulfate anion ($S_2O_8^{2-}$). These are typically oxidizing agents used in various industrial applications, including bleaching, etching, polymerization initiation, and water treatment.

This category serves as a residual for peroxosulfates, distinguishing itself from other classifications by its exclusion of specific enumerated cations. While HTS 2833.40.60.10 covers potassium peroxosulfates and HTS 2833.40.60.20 pertains to ammonium peroxosulfates, this category is for all other metal or non-metal cation-containing peroxosulfates, or those not readily identifiable by cation.

As this is a leaf node, there are no further subcategories to introduce. Classification within this "Other" category relies on the absence of specific enumeration in preceding subheadings and the fulfillment of the general criteria for peroxosulfates as outlined in Chapter 28. Therefore, importers should carefully review the composition of their peroxosulfate products to ensure they do not fall under more specific classifications before assigning HTS 2833.40.60.50.
