Southern African Customs Union (SACU)

SACU is the world's oldest existing customs union, tracing its origins to 1910 and reconstituted under a new agreement in 2002. It comprises five member states and operates on a Common External Tariff (CET) with a shared customs revenue pool — a structural feature that distinguishes a customs union from a simple free trade area, where members retain independent external tariffs.

Key details
  • Five members: South Africa, Botswana, Namibia, Lesotho, and Eswatini
  • Reconstituted via the 2002 SACU Agreement; Secretariat headquartered in Windhoek, Namibia
  • Common External Tariff (CET) plus a Common Revenue Pool distinguish it from an FTA, where each member sets its own external tariff independently
