South Africa Launches Second Sunset Review on Steel Threaded Fasteners Safeguards

South Africa has reached another critical juncture in its trade measures targeting imported iron and steel threaded fasteners.

On March 6, 2026, the WTO Committee on Safeguards circulated a notification confirming that South Africa has formally initiated a second sunset review investigation covering Threaded Fasteners of Iron or Steel. The probe will decide whether to extend the existing safeguard measures, which are scheduled to expire in July 2026.

The investigation was officially launched by the International Trade Administration Commission of South Africa (ITAC) on February 27, 2026, following an application submitted by the South African Fasteners Manufacturers Association (SAFMA).

Products under review include bolt ends, screw studs, threaded studding, and other hexagon nuts. Fasteners made of stainless steel and those specifically designed for aircraft use are expressly excluded.

Case Background

South Africa first launched a safeguard investigation on imported steel threaded fasteners in March 2019. In February 2020, it imposed a three-year safeguard measure in the form of ad valorem duties.

A first sunset review was initiated in March 2023, leading to a three-year extension announced by the WTO in June 2023. The applicable duty rates have been gradually decreasing:

48.04%: July 24, 2023 – July 23, 2024

46.04%: July 24, 2024 – July 23, 2025

44.04%: July 24, 2025 – July 23, 2026

The current measures will expire on July 23, 2026, and the outcome of this second sunset review will determine their future application.

Industry Implications

South Africa remains one of China’s most important export markets for fasteners in Africa. Customs data shows that China’s exports of steel fasteners reached $10.046 billion in 2025, with $78.66 million destined for South Africa, ranking it the 29th largest export destination for Chinese fasteners. An extension of safeguard duties would maintain significant tariff barriers for Chinese exporters.

Notably, this review is separate from the anti-dumping investigation involving Chinese hexagon head screws and bolts, which ITAC terminated on February 5, 2026, after missing the statutory 18-month deadline. The two cases are independent and do not affect one another.

Recommended Responses for Exporters

Clarify product coverage: Confirm tariff classifications, materials and end-use to check whether goods fall within the scope, especially regarding stainless steel and aviation‑exempt products.

Coordinate industry advocacy: Work through trade associations to prepare non-injury arguments and support a favorable ruling.

Engage local partners: Encourage South African importers and downstream users to submit comments to ITAC, highlighting the harm extended duties would cause to automotive, construction and machinery sectors, as well as local employment and supply stability.

Diversify markets: Expand into RCEP economies, Latin America and other regions to reduce reliance on South Africa and spread trade policy risks.
