Legal and legislative discussions regarding firearm control in Brazil have intensified. The Supreme Federal Court (STF) unanimously upheld new registration deadlines established by Decree 11.615/2023, ruling that shortened validity periods for firearm registration certificates apply to existing documents. The court determined these registrations are “administrative authorizations subject to permanent public control,” intended to increase inspection frequency.

Parallel to these legal rulings, a public debate has emerged regarding the traceability of ammunition. Discussions have focused on the necessity of batch marking to assist criminal investigations and prevent the diversion of materials to organized crime. This debate includes scrutiny of past legislative efforts to remove marking requirements and the impact of expanded firearm access for collectors, marksmen, and hunters on criminal supply chains.
