Phosphorus oxychloride (POCl₃), classified under a single 10-digit line (2812120000), is a reactive halide intermediate widely used in agrochemical synthesis, flame retardant production, and pharmaceutical manufacturing. Germany is the leading US supplier, with China and Japan also significant sources; Chinese-origin shipments are subject to Section 301 tariffs, which has reinforced the commercial position of German and Japanese producers for buyers requiring supply-chain cost predictability. Given its corrosive and moisture-sensitive nature, proper hazardous materials documentation — including safety data sheets and UN classification markings — is essential for compliant entry.
