Potassium Permanganate Crystals
Potassium permanganate (KMnO4) is a dark purple crystalline compound used as an oxidizing agent in water treatment and chemical labs. It falls under HTS 2841.69.00.90 as a permanganate salt of a metal (potassium), specifically classified among other manganates and permanganates not elsewhere specified. This chemically defined inorganic salt meets Chapter 28 criteria for metal salts of oxometallic acids.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing vanadium instead of manganese
Vanadates are classified under 2839, a separate heading for salts of oxometallic acids of vanadium.
If put up as retail disinfectant
Disinfectants containing permanganate as active ingredient for retail sale fall under Chapter 38 preparations, not pure salts.
If formulated as fertilizer mixture
Mixtures of potassium permanganate with Chapter 31 fertilizers are excluded from Chapter 28 per chapter note.
