Chemical Mixtures Containing Listed Forms of Phosphorus and Change in Application Process
This rulemaking finalizes a June 25, 2010, notice of proposed rulemaking in which DEA proposed regulations which establish those chemical mixtures containing red phosphorus or hypophosphorous acid and its salts (hereinafter ``regulated phosphorus'') that shall automatically qualify for exemption from the Controlled Substances Act (CSA) regulatory controls. Chemical mixtures containing red phosphorus in a concentration of 80 percent or less and mixtures containing hypophosphorous acid and its salts (hypophosphite salts) in a concentration of 30 percent and less, shall qualify for automatic exemption. DEA is not implementing automatic exemption for any concentration of chemical mixtures containing white phosphorus (also known as yellow phosphorus). Unless otherwise exempted, all material containing white phosphorus shall become subject to CSA chemical regulatory controls regardless of concentration. DEA recognizes that concentration criteria alone cannot identify all mixtures that warrant exemption; therefore, an application process has been implemented which allows manufacturers to apply for exemption from CSA regulatory controls for those phosphorus chemical mixtures that do not qualify for automatic exemption. This rulemaking also finalizes changes to the application review and notification process.
