The structural steel shortage in South Africa now has an official shape. The Southern African Institute of Steel Construction says it has three parts. They are profiles no longer rolled here, profiles rolled here but not available in reasonable lead times, and profiles that may be available locally but whose quality and traceability still have to be demonstrated.
That third category is the one that should change how a supplier sells. Steel that is in the yard but whose traceability has not been demonstrated counts, on the industry body's own definition, as part of the shortage.
What SAISC changed
SAISC first proposed a six month blanket waiver on import tariffs, to bridge the gap until new mills come online. It could not go ahead. The institute says the legislative and administrative requirements, locally and internationally, were too heavy.
It has changed course. SAISC now backs individual applications to the International Trade Administration Commission for tariff waivers, assessed one case at a time against those three criteria. The major associations representing steel manufacturing support the effort, and affected companies are approaching SAISC for credible, independent summaries of the materials in short supply. That is set out in SAISC's own account, adapted from an Engineering News interview with chief executive Amanuel Gebremeskel.
What the piece does not give is a timeline. SAISC says it is working to speed up waiver decisions, but gives no turnaround, and no date for when the new mills arrive. In ITAC's terms a waiver of this kind is a rebate provision or a duty reduction, two of the three tariff applications it handles.
ITAC's published target is four months for a sector in distress and six months for a normal investigation. Practice runs longer. Open tariff investigations had been pending for an average of 34 months by the end of 2025, according to XA Global Trade Advisors' import duty report, as Freight News reported. Engineering News puts the average time to complete one at 27 months.
A supplier promising a client relief by a particular month is promising something nobody has published.
Why the shortage looks like this
The supply side has been rebuilt underneath the market. Structural steel in South Africa was once dominated by one large mill producing from iron ore. There are now several mills making structural steel from recycled scrap. With the closure of ArcelorMittal's Newcastle facilities, SAISC says, many steel members are now imported from around the world.
More sources and more origins mean more paperwork per tonne. A section from a familiar local mill arrived with a history everyone recognised. A section from an unfamiliar mill abroad arrives with whatever documents came with it, and the engineer has to decide whether they are enough.
What the duties add to an imported section
The import route is not cheap. ITAC imposed definitive anti-dumping duties on U, I and H sections from China and Thailand with effect from 19 March 2026, as set out in its announcement. The duty is 74.98% on Chinese sections and 20.32% on Thai ones, Freight News reported.
There is partial relief. On 11 September 2026 SARS amended the tariff so that existing long steel rebates can offset those duties, but only on I and H sections under two tariff subheadings. The wider rebate on structural steel not made in the region is still a proposal. It came out of the second phase of ITAC's steel tariff review, begun in November 2025, and XA Global Trade Advisors noted on 13 September that it had not been implemented.
On 18 September 2026 ITAC published preliminary determinations that again propose rebates, subject to ITAC permits, for structural sections and other long products not available in the SACU market, XA reported. The same determinations propose raising duties on many steel products to their WTO-bound rates. Comments close on 16 October 2026, as Freight News reported. Nothing is final until ITAC decides after that and the Minister and SARS implement it.
Origin already moves the price. On the same commission's recommendation, South Korean hot-rolled steel was added to the safeguard duty in tariff amendments published in the Government Gazette on 4 September 2026. The rate is 11 percent up to 1 May 2027 and 9 percent from 2 May 2027 to 1 May 2028, as Freight News reported for the first period.
That safeguard covers flat-rolled products, coil and plate, not structural sections. We read what that does to a fabricated rate in steel safeguard duty and what it does to your rate. A waiver application now goes to the same body, asking it to lift a tariff on a specific profile, while it holds one in place on another.
Will the engineer accept an imported section?
That depends on whether its quality and traceability can be demonstrated, which is exactly the test SAISC has written into its definition of the shortage. An imported profile with a complete, checkable record answers the engineer's question before it is asked. One without that record is the third kind of shortage, however many tonnes are on the truck.
This is what the Material Quality Certification Programme is for. SAISC is rolling out the MQCP so that growth and innovation do not come at the expense of quality in material supply. Participating suppliers will be audited regularly against its quality and traceability requirements. Gebremeskel says the aim is to give engineers and investors confidence that South African steel remains high quality through the transition.
No rollout date or participant list was given, and none is published on SAISC's site. Until a supplier can show you its certificate, the MQCP is a direction, not a credential you can quote.
What a supplier or fabricator does with this
For a brand selling into a steel package, the three dimensions are a sales script, because each one calls for a different answer.
- Not rolled locally. The question is the waiver. Find out whether SAISC is assembling a summary for that profile and whether an ITAC application is in.
- Rolled locally, but late. The question is programme. Put the lead time in writing on the quote, because a client comparing an import against a local order is comparing dates, not only rands.
- Available, but not traceable. The question is documents. Ask the mill or importer for the full certification before you quote, not after the engineer rejects the delivery.
The SA translation is blunt. A fabricator with forty people cannot carry a delivery that the engineer rejects on traceability. The material is paid for, the shop is waiting and the erection crew is on standing time. That cost lands in a variation dispute, usually with the supplier who sent incomplete papers. Availability is a different problem from price, and the price drivers set upstream of the shop are covered in what carbon tax does to a cement or steel price.
Demand is not the problem. SAISC expects strong demand for light steel frame construction in housing, schools and healthcare, and growth in steel framed bridges. It expects infrastructure activity to strengthen in 2027.
Arabella Infrastructure Solutions is a Johannesburg-based building maintenance and construction company that verifies contractors once and keeps that verification current. What that means for a brand selling into those contractors is on the brand page.
On Monday
Take the five structural profiles you sell most and sort them into SAISC's three categories. For any in the third, request the full mill certification and traceability record from your source this week, before a project asks for it. Then ask SAISC whether it is building a shortage summary for any profile in the first.
