The Southern African Customs Union (SACU) is a customs union among five countries of Southern Africa: Botswana, Eswatini, Lesotho, Namibia and South Africa. Its headquarters are in the Namibian capital, Windhoek. It was established in 1910.
The SACU is the oldest existing customs union in the world.[8]
The first customs union in the area was established in 1889 between the British Cape Colony and the Boer republic of the Orange Free State. In 1891 British Bechuanaland and Basutoland joined, followed by Bechuanaland Protectorate in 1893 and Natal in 1899. Parallel to this process, the Boer republic of the South African Republic and Swaziland (then a protectorate of the South African Republic) formed a customs union in 1894.
Following the Second Boer War, and the establishment of British control over the Boer republics, the Southern African Customs Union was formed in 1903 with the signing of a new Convention and replaced the previous arrangements. It consisted of Cape Colony (to which British Bechuanaland had been annexed in 1895), Basutoland, Bechuanaland Protectorate, Natal, Orange River Colony (the former Orange Free State), Transvaal Colony (the former South African Republic), and Southern Rhodesia. Swaziland joined in 1904 and North-western Rhodesia joined in 1905. In 1906 another convention was signed which superseded the 1903 agreement and retained all of the previous members.[9] [10] In its current configuration it was established in 1910[11] pursuant to a Customs Union Agreement between the Union of South Africa and the High Commission Territories of Bechuanaland, Basutoland and Swaziland. Southern Rhodesia and North-western Rhodesia (later to become Northern Rhodesia after 1911) had declined to join the 1910 Agreement[12] but did maintain a common tariff and free trade arrangements with South Africa and the High Commission Territories (with some variations and exceptions) from 1910 until 1935. An attempt was made in 1949 to re-establish a customs union between South Africa and Southern Rhodesia, but it ultimately failed to do so.[9]
With the advent of independence for the High Commission territories, the agreement was updated and, on 11 December 1969, it was relaunched as the SACU with the signing of an agreement between the Republic of South Africa, Botswana, Lesotho and Swaziland. The updated union officially entered into force on 1 March 1970. After Namibia's independence from South Africa in 1990, it joined SACU as its fifth member, although it had been effectively a part of the customs union from the time of its conquest by South Africa in 1915[13] (with the situation formalized in 1921 with arrangements between South Africa and the South West Africa).[9] Historically SACU was administered by South Africa, through the 1910 and 1969 Agreements. The customs union collected duties on local production and customs duties on members' imports from outside SACU.
As of 2007, the Executive Secretary of the SACU was Tswelopele C. Moremi. Paulina Mbala Elago, a Namibian national, became executive secretary on 1 April 2014 for a period of five years. Thabo David Khasipe was appointed as executive secretary on 1 February 2023.[14]

The union meets annually to discuss matters related to the Agreement. In addition, the Customs Technical Liaison Committee, the Trade and Industry Liaison committee and the Ad hoc Sub-Committee on Agriculture each meet three times a year.
Its aim is to maintain the free interchange of goods between member countries. It provides for a common external tariff and a common excise tariff to this common customs area. All customs and excise collected in the common customs area are paid into South Africa's National Revenue Fund. The revenue is shared among members according to a revenue-sharing formula, as described in the agreement. South Africa is the custodian of this pool. Only the BLNS Member states' shares are calculated, with South Africa retaining the residual. SACU revenue constitutes a substantial share of the state revenue of the BLNS countries.
Following the formation of the Government of National Unity in South Africa in April 1994, member states concurred that the existing agreement should be renegotiated to democratise SACU and address needs of the SACU member states more effectively. With this in mind, the Ministers of Trade and Industry of the five member states met in Pretoria on 11 November 1994 to discuss the renegotiation of the 1969 agreement. The Ministers appointed a Customs Union Task Team (CUTT), which was mandated to make recommendations to the Ministers. CUTT has met on numerous occasions in the member states, and declares that good progress has been made in the renegotiation process.
At a meeting of Ministers of Trade and Finance Departments from the SACU member states, held in Centurion, Pretoria on 5 September 2000, the Ministers reached consensus on the principles underpinning institutional reform in the SACU. The institutional administrative structure of the revenue pool was agreed as follows:
SACU ministers further agreed that the revenue share accruing to each member state should be calculated from three basic components:
By agreement, these components would be distributed as follows:
While SACU entered into a free trade deal with the four-nation European Free Trade Association on 1 July 2006, its negotiations with the United States for a free trade agreement have stalled (as of 8 January 2008).[17]
SACU is involved in negotiations for a free trade agreement - the Economic Partnership Agreements (EPAs) - with the EU, and the organisation corresponded with the EU Trade Commissioner, Karel De Gucht, between February and March 2010, to request that the EU not demand ratification and implementation of the EPAs at the next round of negotiations without the concerns of the SACU countries being addressed. De Gucht replied that he would like to "invite the SADC EPA countries concerned to swiftly complete signature, notification and implementation of the interim EPA" and that "in the meantime, the EU is more than willing to address all pending issues and concerns."[18] [19] [20]
