Both diammonium phosphate (DAP) and monoammonium phosphate (MAP) fall within HTS Chapter 31, but they are classified in distinct subheadings based on their ammonium-to-phosphate ratio and nutrient content. Lab certification of the N-P ratio is standard practice for customs entry, as the nutrient grade determines the applicable subheading and any associated duty or trade-remedy treatment.
Yes. The US International Trade Commission and Department of Commerce have conducted countervailing duty investigations on phosphate fertilizers from certain major producing countries. Importers should check the current status of any orders or preliminary determinations with the Department of Commerce before finalizing purchase contracts, as CVD cash deposit requirements can significantly affect landed cost.
