Last updated: July 2026 dataPotassium phosphate serves as a critical input across food processing, pharmaceutical formulation, and fertilizer manufacturing, where precise purity grades determine end-use suitability. Israel leads US import supply, followed by France and Germany, reflecting Europe's established specialty chemical production base. The single US tariff line 2835240000 captures all forms — mono-, di-, and tripotassium phosphate — so importers must ensure the correct chemical specification is documented on entry paperwork to avoid reclassification disputes. Food-grade and pharmaceutical-grade shipments may be subject to FDA review at the port of entry.

Yes. The US schedule consolidates all potassium phosphate salts under 2835240000 regardless of the potassium-to-phosphate ratio. Importers should clearly identify the specific salt form on commercial invoices and certificates of analysis to support any downstream regulatory or quality requirements, even though the customs classification does not distinguish between them.
Food-grade and pharmaceutical-grade potassium phosphate may be subject to FDA admissibility review, including examination of labeling, purity specifications, and the foreign manufacturer's compliance history. Importers are advised to maintain certificates of analysis and supplier documentation. Classification and admissibility are complex; consult a licensed customs broker or FDA-registered agent before shipment.
