Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If single/double superphosphate mixtures regardless of fluorine content
Superphosphate-based mixes fall under 3103 even when blended with other phosphatics, unlike pure ammonium salts
If diammonium hydrogenorthophosphate with added potassium
NPK formulations containing diammonium phosphate shift to 3105.30 for two/three element fertilizers
If technical grade for non-fertilizer industrial use
Same chemical excluded from Chapter 31 when used in manufacturing vs agricultural fertilizer applications

Import Tips & Compliance
• Confirm granulation size and purity meets commercial grade specs to prevent reclassification as industrial chemical
• Provide material safety data sheets (MSDS) documenting non-explosive fertilizer grade vs industrial ammonium phosphate
• Check for anti-dumping duties from specific origins like Morocco or China on DAP imports
