Unserialized Firearm Harm Oversight and Serialization Act of 2026

This bill requires licensed firearm dealers to add serial numbers to unserialized guns they receive and to those they manufacture using 3D printing or similar non-traditional methods. It defines additive manufacturing as layer-by-layer processes like 3D printing and mandates that dealers engrave or cast serial numbers on frames and receivers, then report this information to the Attorney General. Dealers who fail to comply face civil fines up to $10,000 for first offenses and criminal penalties including up to $100,000 in fines and one year in prison for subsequent violations. The bill also creates a tax credit for dealers who spend money on serialization equipment and limits how the Attorney General can use the collected serial number data to only active criminal investigations. State laws regarding firearm serialization remain unaffected by these federal requirements.
