Last updated: August 2026 dataDicalcium phosphate — widely traded under the abbreviation DCP — is a foundational ingredient in animal feed, dietary supplements, and dental products, where its calcium and phosphorus content and particle size are tightly specified by buyers. China is the dominant US import source for this commodity, with Germany and India also supplying meaningful volumes. The single tariff line 2835250000 covers all grades, but feed-grade and food-grade DCP face different regulatory scrutiny: feed-grade imports may require USDA APHIS documentation, while food or supplement grades are subject to FDA review. Importers should confirm grade-specific compliance requirements before shipment.

Feed-grade DCP intended for animal nutrition may require compliance with USDA APHIS regulations and applicable feed safety standards, while food- or supplement-grade DCP falls under FDA oversight. The HTS classification (2835250000) is the same for both, so the grade designation on the commercial invoice, certificate of analysis, and intended end-use declaration are critical for determining which agency review applies at entry.
China's large-scale phosphate mining and chemical processing infrastructure gives it a significant cost advantage in producing commodity-grade DCP. However, importers sourcing from China should be aware of potential Section 301 tariff exposure on this product and should verify current duty treatment with a licensed customs broker before contracting.
