Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If phosphorus oxychloride (POCl3) instead of PCl3
Different chemical formula classified separately in same heading as chloride oxide.
If pre-formulated as pesticide intermediate
Herbicide intermediates fall under Chapter 38 pesticides.
If further reacted to form chlorinated phosphorus esters
Organic phosphorus compounds move to Chapter 29.

Import Tips & Compliance
• Declare exact concentration and impurities; >98% purity confirms 2812 classification over mixtures
• Comply with TSCA import requirements and pre-notify CBP for fuming liquid shipments
• Use stainless steel or glass-lined containers to prevent decomposition during transit
