Last updated: August 2026 dataAluminum phosphide and zinc phosphide are the commercially dominant members of this heading, used primarily as grain fumigants that release toxic phosphine gas upon contact with moisture — a property that makes them effective rodenticides and insecticides in stored-commodity protection. Calcium phosphide and other metal phosphides serve as specialty reagents in organic synthesis and semiconductor doping. Because aluminum phosphide and zinc phosphide are registered pesticides, US imports are subject to EPA FIFRA registration requirements, and shipments must be accompanied by appropriate labeling and safety documentation.

Aluminum phosphide products used as pesticides must be registered under FIFRA. Imported formulations must either carry an EPA registration number or qualify as an identical or substantially similar product to a registered domestic product. Importers should coordinate with EPA's Office of Pesticide Programs and ensure that labeling meets US requirements before the shipment arrives at the port of entry.
Ferrophosphorus is an iron-phosphorus alloy produced as a byproduct of phosphorus furnace operations and is classified among ferroalloys rather than with chemically defined phosphides. The exclusion reflects its metallurgical rather than chemical character — it is used as a steel additive, not as a reactive phosphide compound.
