Official summary

Written by the Congressional Research Service (CRS), Library of Congress for the version “Public Law”, July 17, 2025. Reproduced verbatim.

Halt All Lethal Trafficking of Fentanyl Act or the HALT Fentanyl Act

This act permanently places fentanyl-related substances as a class into schedule I of the Controlled Substances Act. A schedule I controlled substance is a drug, substance, or chemical that has a high potential for abuse; has no currently accepted medical value; and is subject to regulatory controls and administrative, civil, and criminal penalties under the Controlled Substances Act.

Under the act, offenses involving fentanyl-related substances are triggered by the same quantity thresholds and subject to the same penalties as offenses involving fentanyl analogues (e.g., offenses involving 100 grams or more trigger a 10-year mandatory minimum prison term).

Additionally, the act establishes a new, alternative registration process for certain schedule I research.

The act also makes several other changes to registration requirements for conducting research with controlled substances, including

• permitting a single registration for related research sites in certain circumstances,

• waiving the requirement for a new inspection in certain situations, and

• allowing a registered researcher to perform certain manufacturing activities with small quantities of a substance without obtaining a manufacturing registration.

Finally, the act expresses the sense that Congress agrees with the interpretation of the Controlled Substances Act in United States v. McCray, a 2018 case decided by the U.S. District Court for the Western District of New York. In that case, the court held that butyryl fentanyl, a controlled substance, can be considered an analogue of fentanyl even though, under the Controlled Substances Act, the term controlled substance analogue specifically excludes a controlled substance.

Official title

A bill to amend the Controlled Substances Act with respect to the scheduling of fentanyl-related substances, and for other purposes.
