Last updated: July 2026 dataElemental phosphorus — classified under the single line 2804700000 — is produced in white, red, and black allotropic forms, each with distinct hazard profiles and end-use applications ranging from flame retardants and agrochemicals to semiconductor dopants. Vietnam and Kazakhstan are the leading US import sources, reflecting large-scale electric-furnace phosphorus production in those countries. White phosphorus in particular is subject to strict DOT hazardous materials regulations due to its pyrophoric nature, and certain forms may trigger EPA Toxic Substances Control Act (TSCA) reporting requirements. Importers should confirm allotrope identity and packaging compliance well before shipment, as misclassification of the allotropic form can create both safety and regulatory complications at the port.

Yes, significantly. White phosphorus is pyrophoric and classified as a DOT hazardous material requiring specialized packaging, placarding, and handling. Red phosphorus is considerably more stable and carries a different hazard classification. Both may require TSCA reporting, but white phosphorus triggers additional safety and security scrutiny at entry.
Both countries operate large electric-arc-furnace phosphorus production complexes originally developed to exploit domestic phosphate rock deposits and low-cost energy. Vietnam's facilities have expanded significantly in recent years, making it a primary source for US industrial buyers.
