Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If actually potassium hydroxide
Caustic potash (KOH) is in adjacent subheading 2815.20; chemical composition determines heading.
If other inorganic compounds like phosphides
Heading 2853 covers complex compounds like copper phosphide, not simple alkali peroxides.
If in chemical preparations or mixtures
Mixed with organics or in preparations, shifts to Chapter 38 per Note 1 exclusions.
