## Abstract

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. 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 proposes changes to the application review and notification process. While preparing this rulemaking, DEA became aware that references to section 1018 of the Act (21 U.S.C. 971) were inadvertently omitted from 21 CFR 1310.12(a) and 1310.13(i). Therefore, DEA is proposing that this rulemaking amend these sections by adding this citation. This insertion is a clarification and does not alter the current treatment of exempt chemical mixtures under the CSA.
