Products classified under HTS 2809.20.00.20
Fertilizer Grade Phosphoric Acid 52% P2O5
This is a liquid phosphoric acid solution with 52% P2O5 content, specifically produced for use in manufacturing compound fertilizers like NPK blends. It falls under HTS 2809.20.00.20 as 'other' fertilizer grade phosphoric acid, distinct from merchant grade due to its lower purity and higher impurities suitable for direct fertilizer application. Polyphosphoric forms are excluded as this is monophosphoric acid.
Wet Process Phosphoric Acid for DAP Fertilizer
Wet-process phosphoric acid derived from phosphate rock, containing 52-54% P2O5 with typical impurities like fluorides and sulfates, used primarily in diammonium phosphate (DAP) production. Classified under HTS 2809.20.00.20 as fertilizer grade 'other' due to its specific formulation and lower purity optimized for fertilizer manufacturing rather than technical applications.
52% P2O5 Phosphoric Acid for NPK Fertilizer Production
Industrial-grade phosphoric acid at 52% P2O5 concentration from wet process, designed for blending into nitrogen-phosphorus-potassium (NPK) fertilizers. It qualifies for HTS 2809.20.00.20 as 'other' fertilizer grade phosphoric acid, differentiated by its cost-effective impurity levels unsuitable for food or pharma uses.
Merchant-Impure Phosphoric Acid for Bulk Fertilizers
Lower-purity phosphoric acid (52% P2O5) with elevated green/dyellow impurities, sourced for large-scale fertilizer production like triple superphosphate. Under HTS 2809.20.00.20 as fertilizer grade 'other,' it meets chapter notes for chemically defined phosphoric acid used in agriculture.
Green Liquor Phosphoric Acid 53% P2O5 Fertilizer Grade
Dark green phosphoric acid from wet process with 53% P2O5, high in organic impurities, exclusively for fertilizer use in MAP/DAP plants. Classified in HTS 2809.20.00.20 as 'other' fertilizer grade per subheading for phosphoric acid not elsewhere specified.
