# DEA list of chemicals

The United States Drug Enforcement Administration (DEA) maintains lists regarding the classification of illicit drugs (see DEA Schedules). It also maintains List I of chemicals and List II of chemicals, which contain chemicals that are used to manufacture the controlled substances/illicit drugs. The list is designated within the Controlled Substances Act but can be modified by the U.S. Attorney General as illegal manufacturing practices change.
Although the list is controlled by the Attorney General, the list is considered a DEA list because the DEA publishes and enforces the list.
Suppliers of these products are subject to regulation and control measures:
| Regulation | List I | List II | Tableting and Encapsulating Machines | Special Surveillance List |
| Know your customer | X | X | X | X |
| Annual manufacturing, inventory, and use reports for bulk manufacturers | X | X | X | |
| 15 day advanced DEA notice required for imports, exports, and transshipments | X | X | | |
| 15 day advanced DEA notice required for international transactions | X | X | | |
| Keep transaction records for at least two years | X | X | | |
| Maintain effective security controls | X | X | | |
| Required reporting for unusual sales and losses or sales to DEA-identified companies | X | X | | |
| Registration required for manufacturing, distribution, import, or export | X | | | |
| Reports of mail-order sales to non-regulated entities | X | | | |

For each chemical, its illicit manufacturing use is given in parentheses. Some Special Surveillance List chemicals do not have an exclusive manufacturing use for a specific illicit drug but rather have a broad range of uses in both legitimate and illicit manufacturing operations.
