Monopotassium Phosphate (MKP)
Monopotassium phosphate, chemically defined as KH2PO4, is a soluble salt used primarily as a fertilizer providing potassium and phosphorus to plants. It falls under HTS 2835.24.00.00 as a phosphate of potassium, distinct from other salts due to its specific chemical composition meeting Chapter 28 definitions.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported specifically as a fertilizer for retail sale
Goods of Chapter 31 like fertilizers take precedence over Chapter 28 chemical classification per Note 2 to Section VI.
If blended with other substances exceeding chemical purity thresholds
Mixtures not chemically defined fall in heading 3824 rather than specific Chapter 28 inorganic compounds.
