Phosphorus Oxychloride

Phosphorus oxychloride (POCl₃) is a reactive chlorinating and phosphorylating agent classified under US tariff line 2812120000, serving as a key intermediate in flame retardant production, agrochemical synthesis, and semiconductor doping processes. Germany leads US import supply, followed by China and Japan, with India also a notable source — a supplier mix that spans both high-purity electronic-grade and industrial-grade material. Its corrosive and moisture-sensitive nature requires specialized packaging and transport, and importers should verify compliance with DOT hazardous materials regulations.
