The South African government has imposed steep anti-dumping duties on structural steel imports from China and Thailand in a decisive move to protect its struggling domestic industry. The new measures, released on the 19th of March 2026, which will remain in place for five years, follow a surge in low-cost imports that severely undercut local producers.
The tariffs will see Chinese structural steel hit with duties of nearly 75%, while imports from Thailand will face levies exceeding 20%. Authorities found that imported steel was being sold at prices about 20% lower than locally produced products, a practice that significantly disrupted the market and placed intense pressure on manufacturers.
Imports from the two countries increased nearly 19-fold during the 2023/24 financial year, amplifying concerns about the sustainability of the local steel sector. The impact has been particularly severe for ArcelorMittal South Africa, whose rail and structural steel division has come under strain amid increasing competition from cheaper imports.
The decision follows an investigation by trade authorities, which confirmed clear evidence of dumping and material harm to the domestic industry. It also comes at a critical time, as the government continues discussions with the Industrial Development Corporation and ArcelorMittal South Africa to support its long steel business after plant closures last year put up to 3,500 jobs at risk.
By enforcing these anti-dumping duties, the government aims to stabilise the local steel market, safeguard jobs, and ensure the long-term viability of one of the country’s key industrial sectors.
