Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If P2O5 equivalents reach 65% or higher
Concentrated polyphosphoric blends for fertilizers use the higher concentration subheading.
If converted to metal phosphates like dicalcium phosphate
Phosphoric acid reacted with bases forms phosphites/phosphates classified as inorganic salts.

Import Tips & Compliance
• Distinguish from pure polyphosphoric acids (>84% P2O5) via assay reports; CBP may require independent testing
• Declare as 'polyphosphoric acids' if chain length >1; affects duty but stays in same base heading
• Monitor for seasonal fertilizer tariffs; bulk imports need warehouse bonds for deferred duties

Fertilizer Grade Phosphoric Acid 52% P2O5
This is a liquid phosphoric acid solution with approximately 52% available P2O5 equivalents, specifically formulated for use in agricultural fertilizers. It falls under HTS 2809.20.00.10 because it is phosphoric acid containing less than 65% P2O5, designated as fertilizer grade. Commonly used to produce phosphate fertilizers like MAP and DAP.
Merchant Grade Phosphoric Acid 54% P2O5
Merchant grade phosphoric acid (MGA) at 54% P2O5 is a wet-process acid used primarily in fertilizer manufacturing. Classified under HTS 2809.20.00.10 due to its P2O5 content below 65% and fertilizer grade specification. It is the standard input for global phosphate fertilizer production.
Low Concentration Fertilizer Phosphoric Acid 48% P2O5
A 48% P2O5 phosphoric acid solution optimized for liquid fertilizer formulations and direct soil application. It qualifies for HTS 2809.20.00.10 as fertilizer grade phosphoric acid with less than 65% available P2O5 equivalents. Ideal for foliar feeding and fertigation systems.
Wet Process Phosphoric Acid 55% P2O5 for MAP Production
Wet-process derived phosphoric acid at 55% P2O5, standard feedstock for monoammonium phosphate (MAP) fertilizer. HTS 2809.20.00.10 applies to this fertilizer grade acid with <65% P2O5. Produced via sulfuric acid digestion of phosphate rock.
