Drug Enforcement Administration June 25, 2010 – Federal Register Recent Federal Regulation Documents

The DEA is proposing regulations which establish those chemical mixtures containing red phosphorus, white phosphorus (also known as yellow phosphorus), or hypophosphorous acid and its salts (hereinafter ``regulated phosphorus'') that shall automatically qualify for exemption from the Controlled Substances Act (CSA) regulatory controls. DEA is proposing that 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 proposing automatic exemption for chemical mixtures containing white phosphorus. Unless otherwise exempted, all material containing white phosphorus shall become subject to CSA chemical regulatory controls regardless of concentration.
