The Southern African Customs Union (SACU) is a prominent economic association of the African continent. SACU comprises five southern African countries: South Africa, Botswana, Namibia, Lesotho, and Eswatini. The overall value of India’s trade with SACU increased from $1,477.52 million in 2001 to $1,0941.24 million in 2020, an almost sixfold increase. The export increased almost tenfold between 2001 and 2020, from US$ 343.49 million to US$ 3,760.94 million. In order to increase India’s trade with SACU, the Indian-SACU PTA negotiations are now ongoing. This article examines India’s export potential to SACU nations using the revealed comparative advantage index, the revealed import dependency index, and the Potential bilateral trade equation. The study shows India has trade potential with all SACU member states. Still, it has only utilised this potential with South Africa. India has not taken advantage of the vast potential of exporting its goods to SACU countries except South Africa. The trade intensity index indicates that India’s export and import intensities with SACU have increased over time.
