Is Brass Knuckles Legal in Brazil After the 2026 Framework Overhaul?

No, brass knuckles are classified as prohibited weapons under Brazil’s Estatuto do Desarmamento (Law 10.826/2003), with possession or carrying punishable by 2 to 4 years imprisonment. The Federal Police (Polícia Federal) enforces strict controls, and recent 2026 amendments expanded banned items to include improvised or disguised weapons, tightening compliance for collectors and security firms.


Key Regulations for Brass Knuckles in Brazil

  • Prohibition Under Law 10.826/2003: Brass knuckles are explicitly listed as “armas brancas” (edged weapons) in Annex I, Article 3, with no exceptions for historical or ceremonial use.
  • Federal Police Authorization: Only licensed security companies or military personnel may request exemptions, requiring prior approval from the Departamento de Polícia Federal (DPF) under Decree 5.123/2004.
  • 2026 Compliance Shifts: Amendments to the Regulamento de Produtos Controlados (R-105/2004) now classify brass knuckles as “armas de uso restrito,” mandating secure storage in registered armories and annual inspections by the Comando do Exército.
