South African authorities have warned that U.S. reciprocal tariffs could put an estimated 30,000 jobs at risk.

South Africa’s government is putting the final touches to an overarching package that aims to shield businesses against the fallout from punitive US trade tariffs and plans to present it to lawmakers later this week.

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.

Democratic-led states and U.S. businesses challenging tariffs in court argue that IEEPA does not cover tariffs, and that Congress has authority over tariffs and taxes.

The tariffs are a substantial new source of revenue for the federal government. The budget may start to depend on it.

President Donald Trump imposed sweeping tariffs on nearly all of the United States’s trading partners on July 31, the latest move in his aggressive trade policy that he says will spur domestic manufacturing in the United States.
