Last updated: August 2026 dataPhosphorus trichloride (PCl₃) is a high-volume reactive intermediate for organophosphorus chemistry, serving as a building block for pesticides, plasticizers, and specialty pharmaceuticals. Germany leads US supply, with India and China also among the top sources; the concentration of supply among these three countries means that regulatory or logistics disruptions in any one market can materially affect availability for downstream formulators. Like other phosphorus halides, PCl₃ is moisture-sensitive and corrosive, requiring careful hazardous materials compliance throughout the import process.

Phosphorus trichloride (PCl₃) contains no oxygen and classifies under HTS 2812130000, while phosphorus oxychloride (POCl₃) is an oxyhalide and classifies under 2812120000. The chemical formula and CAS number on the supplier's certificate of analysis are the definitive classification evidence; the two compounds are not interchangeable in either chemistry or tariff treatment.
Phosphorus trichloride is a precursor chemical monitored under international chemical weapons conventions, and some supplier countries impose export licensing requirements. Importers should request export compliance documentation from their supplier and verify that the shipment is accompanied by appropriate end-use certifications to avoid delays at the US port of entry.
