: In most jurisdictions, white phosphorus is strictly controlled under hazardous materials and chemical weapons regulations. It is often classified as a dual-use item , meaning its sale is monitored by government agencies to prevent misuse in weapons or illicit activities.

White phosphorus is an chemical substance. It is not something that can be purchased through typical retail channels or by the general public due to its intense reactivity and legal restrictions. Restrictions and Availability

: Because white phosphorus ignites spontaneously when exposed to air (pyrophoric), it must be stored and shipped under water or an inert gas. It is also highly toxic if ingested or inhaled. Safety and Professional Requirements

: It is primarily available only to verified industrial, military, or academic research institutions . Legitimate chemical suppliers (such as Sigma-Aldrich) require buyers to have a registered business or laboratory account, provide a clear "statement of use," and comply with rigorous shipping and storage protocols.

Handling white phosphorus requires specialized training and specialized facilities. Before any legitimate institution considers the use of such a substance, it is necessary to review the CDC/NIOSH guidelines and consult with an Environmental Health and Safety (EHS) department. This ensures that all necessary permits are in place and that the facility is equipped to manage the significant fire and toxicity risks associated with pyrophoric materials.
