Eliminating Obsolete Marking Requirements for Toy, Look-Alike, and Imitation Firearms

By this rule, NIST removes its regulation setting forth marking requirements for toy, look-alike, and imitation firearms. Pursuant to statutory amendments made by the CHIPS and Science Act of 2022, the subject regulation now lacks an underlying statutory authorization and has been rendered obsolete by the new, operative marking requirements issued by the Consumer Product Safety Commission (CPSC). The removal of the subject NIST regulation is therefore necessary to reflect the current state of the underlying law and to eliminate obsolete regulatory language. This action is intended to minimize the risk of public confusion regarding the applicable marking requirements and governing authority for toy, look-alike, and imitation firearms and to promote administrative efficiency.
