Single-nutrient headings (3102 for nitrogen, 3103 for phosphorus, 3104 for potassium) apply only when the product contains one primary nutrient. A product containing two or three of those nutrients—or a mixture packaged for retail sale—is classified under 3105, which covers compound and mixed fertilizers as well as retail-packed fertilizer products.
Certain nitrogenous fertilizers from Russia have been subject to antidumping and countervailing duty orders. Importers should verify the current order status and applicable scope for the specific product and tariff line before shipment, as coverage and rates can change.
