🌊 1. Strait of Hormuz: From “Closure” to “Permanent Cost”
Iran’s parliament is finalizing legislation to charge transit fees for all vessels passing through the Strait of Hormuz .
| What’s Changing | Details | Source |
|---|---|---|
| Fee structure | Draft law to set fees based on vessel type, cargo value, and flag | Tasnim |
| Implementation | Could take effect within weeks once finalized | |
| Enforcement | Will be managed under Iran’s newly established “control system” | Lloyd’s List |
What this means for buyers:
- Gulf-bound steel will carry a new permanent cost line item
- “Risk premium” in CFR pricing becomes structural, not temporary
- Action: Factor an additional $5–15/t into landed cost assumptions for UAE/Saudi shipments

🇿🇦 2. South Africa: Final AD on Structural Steel Now in Force
The International Trade Administration Commission of South Africa (ITAC) issued its final determination on structural steel from China and Thailand .

🇬🇧 3. UK Tariffs: 3‑Month Window Remains
The UK’s new steel import regime is confirmed for July 1, 2026 :
| Measure | Detail |
|---|---|
| Quota reduction | 60% cut from 2025 import levels |
| Over‑quota tariff | 50% |
| Transition relief | Contracts signed before March 14, arriving July–Sept, are exempt |
What this means for buyers:
- If you source steel that can be produced in the UK, move material before July 1
- UK HRC prices already up £550/t → £800/t+ in anticipation
- Action: Lock in shipments for June arrival; avoid over‑quota exposure

🇨🇳 4. China Demand: Inventory Draw Confirms Stabilization
Mysteel’s weekly data (March 26) shows continued demand improvement :
| Indicator | Change | Trend |
|---|---|---|

| Rebar mill inventory | -170.4 kt (-7.21%) | 2nd week of draw |
| Rebar social inventory | -104.6 kt (-1.60%) | 2nd week of draw |
| HRC social inventory | -69.1 kt | First decline |
What this means for buyers:

📊 Summary Impact Matrix
| Market | Product | Risk / Opportunity | Action |
|---|---|---|---|
| UAE / Saudi | All | New Hormuz transit fee incoming | Add $5–15/t to cost models |
| South Africa | Structural steel | Chinese supply effectively blocked | Shift to India, Turkey, Korea |
| UK | All UK‑producible steel | 3‑month window before 50% tariff | Rush orders before July 1 |
| Global | Steel | China demand stabilizing | Consider restocking now |
🎯 Actionable Takeaways
| Buyer Type | Priority Action |
|---|---|
| UAE / Saudi buyers | Build permanent $5–15/t “strait fee” into CFR cost baselines. The risk premium is no longer temporary. |
| South Africa buyers | Stop all new structural steel orders from China. Evaluate India (JSW, Tata) and Turkey as alternatives. |
| UK buyers | Use the next 3 months to pull forward any orders that would fall under the 50% over‑quota tariff. |
| All buyers | China’s demand recovery is real—inventory draws and rising apparent demand signal a price floor. Procrastination carries cost. |
