South Africa on Monday outlined support measures for local companies that will be hit by a 30% U.S. tariff this week, including exemptions from some competition rules and financial support facilities.

The Departments of International Relations and Cooperation and Trade Industry and Competition have announced a plan of action in response to the US tariffs – details to come later.

South Africa faces the highest rate in sub-Saharan Africa, reflecting Trump's strained relationship with the government of President Cyril Ramaphosa. Other African nations, including Nigeria, Ghana, Lesotho and Zimbabwe have been hit with a 15% tariff, which will also come into effect in seven days.
