VI. Trade Regulations and Standards In these matters the general framework of the economy of South Africa is even more important to an understanding of the Swazi economy. Swaziland is party to the South African Customs Union (SACU) and its standards and regulations in trade are marked by this organization of which Lesotho, Botswana, and Namibia are also members. The policies of SACU are in fact set by its largest member South Africa. Trade flows freely inside the SACU area. While there are no general restrictions on imports into Swaziland certain items do require import licenses. Information about items requiring import licenses must be obtained directly from the office of Customs and Excise. For exports to qualify as "Made in Swaziland" they must as a general rule have 25% local content. There are various other preferences and requirements depending on the destination of the exported goods. Certain Swazi exports enjoy preferential tariff treatment through the Generalized System of Preferences, the Lome Convention and the Common Market for East and Southern Africa.
