HS Code for Ammonium phosphate

Ammonium phosphate refers to a group of inorganic chemical compounds, such as monoammonium phosphate (MAP) and diammonium phosphate (DAP). These compounds are classified under HS Chapter 28, which encompasses inorganic chemicals. Heading 2835 specifically covers phosphinates, phosphonates, phosphates, and polyphosphates. Subheading 2835.29 is designated for "Phosphates; (other than of mono- or disodium, other than of potassium or of calcium hydrogenorthophosphate (dicalcium phosphate) and excluding other phosphates of calcium), whether or not chemically defined". This subheading serves as a residual category for phosphates not explicitly covered by more specific subheadings within 2835.2X, making it the appropriate classification for ammonium phosphates.

Products Included

• Monoammonium phosphate (MAP)
• Diammonium phosphate (DAP)
• Ammonium polyphosphate
• Other ammonium salts of phosphoric acid not specified elsewhere

Common Misclassification

Ammonium phosphate can be misclassified with other phosphate compounds. For instance, sodium phosphates are classified under HS code 2835.21, potassium phosphates under 2835.22, and calcium hydrogenorthophosphate (dicalcium phosphate) under 2835.25. It is crucial to differentiate ammonium phosphates from these specific metal phosphates. Furthermore, confusion may arise with phosphinates (2835.10) or polyphosphates (2835.3X). The key to correct classification is recognizing that 2835.29 is the specific residual category for phosphates that are not of sodium, potassium, or specific calcium forms, ensuring accurate placement for ammonium phosphates.
