The
Chemical Diversion and Trafficking Act of
1988 was an amendment to the
Controlled Substances Act to regulate
Precursor chemicals, essential chemicals, tableting machines, and encapsulating machines by imposing record keeping and import/export reporting requirements on transactions involving these materials. Prior to these restrictions being put in place, the U.S. had been the primary source of chemicals used in
South American cocaine manufacture. According to the DEA, the Act sharply reduced these precursor exports and cocaine manufacturers responded by purchasing from chemical suppliers outside the U.S. The U.S. in turn successfully lobbied for inclusion of chemical controls in the
1988 United Nations Convention Against Illicit Traffic in Narcotic Drugs and Psychotropic Substances, which included two Tables of controlled precursors.
