The UK’s new steel trade measure went live on 1 July 2026, and the first month has already surfaced the pressure points importers need to watch. The headline numbers: tariff-free import quotas cut by 51% compared to the old safeguard, and a 50% tariff on anything above quota. The previous 25% safeguard duty ceased on 30 June.
This is not a preview any more. Quota is being drawn down. The transitional exemption window closes on 30 September. And the late-June deal between the UK and EU on coordinated quota approaches has reshaped the landscape for importers who source from both sides of the Channel.
This article covers what the measure actually looks like in operation, corrects several details that changed between the March announcement and the July implementation, and sets out what importers should be doing right now.
What the Measure Actually Does
The steel trade measure, announced on 19 March 2026 and implemented under the Taxation (Cross Border Trade) Act 2018, replaces the steel safeguard that had been in place since 2018. The government’s stated aim is to protect domestic steelmaking capacity, which it describes as “essential to the resilience and security of the UK’s critical national infrastructure and defence supply chains.”
The numbers that matter:
- 51% quota reduction — overall tariff-free import volumes cut by 51% compared to the previous safeguard measure. (Early reporting used a 60% figure; the final measure settled at 51%.)
- 50% out-of-quota tariff — applied ad valorem on the CIF value. For a £500,000 shipment of hot-rolled coil, that’s £250,000 in additional duty if quota is exhausted.
- 20 product categories — covering hot-rolled and cold-rolled sheets, coated products, quarto plates, merchant bars, rebars, wire rod, angles and sections, railway material, hollow sections, welded tubes, and more.
- Quarterly quota periods — Q1 (Jul–Sep), Q2 (Oct–Dec), Q3 (Jan–Mar), Q4 (Apr–Jun). The quota year runs 1 July to 30 June.
- Unused quota rolls to the next quarter — but expires at the end of the quota year on 30 June. No carry-forward between years.
The measure applies to imports of steel products that can be made in the UK. The government’s case rests on OECD data showing global steel overcapacity projected to reach 721 million metric tonnes by 2027 — 13% more than total OECD production capacity. UK crude steel production has fallen by more than 50% over the past decade.
One Month In: Early Indicators
The measure has been live since 1 July. Key observations:
Quota drawdown is uneven. Country-specific quotas for high-demand categories are being consumed faster than expected, particularly EU-origin Category 1 (hot-rolled sheets) and Category 4 (metallic coated sheets). Residual quotas — the catch-all for countries without dedicated allocations — are under pressure as importers pivot away from exhausted country quotas.
The transitional exemption is being tested. Importers with pre-14 March 2026 contracts are submitting evidence to HMRC. The 2 June 2026 implementation notifications detail the requirements. Early feedback suggests HMRC is scrutinising contract dates closely — verbal agreements and framework contracts without fixed quantities are being rejected.
Prices are shifting. Domestic UK steel prices have risen approximately 8-12% since the March announcement, with further increases expected as quota exhaustion spreads.
The authorised use route is operational but slow. Importers report 2-3 week processing times for Category 1 downstream processing authorisations. The 40% country cap means single-country dependency is now a real constraint.
The EU Deal: Coordinated Quotas
In late June 2026, the UK and EU agreed a coordinated approach to their respective steel trade measures, reflecting their “highly interconnected supply chains.” The EU simultaneously reduced its overall steel quota by 47% to approximately 18.3 million tonnes per year.
The coordination means no double jeopardy for steel moving between the UK and EU for processing, broadly aligned product categories reducing classification disputes, and shared quota utilisation monitoring. For UK importers sourcing from EU mills, the EU quota cut matters because it affects EU mill availability and pricing — if EU mills face their own quota constraints, they may prioritise or redirect supply.
Corrected: Announcement vs Implementation
Several details in the final measure differ from early reporting. Importers working from March/April coverage should note:
Quota cut: 51%, not 60%. The government’s final measure reduced quotas by 51% compared to the safeguard, not the 60% figure in early trade press. Confirmed in the official GOV.UK information note.
Unused quota rolls over within the quota year. Early reports stated no carry-forward. The final measure allows unused country-specific and residual quota to roll into the next quarter within the same quota year. It does not carry between quota years.
Transitional exemption is a full exemption, not a separate quota pool. The 2 June 2026 implementation notification confirms goods under contract before 14 March 2026 and imported by 30 September are “fully exempt” from the 50% duty — not allocated to a separate pool as earlier guidance suggested. The evidence bar is high.
Category numbering uses non-sequential codes. The 20 categories use numbers 1, 4, 5, 6, 7, 12A, 12B, 13, 14, 15, 16, 17, 19, 20, 21, 25A, 25B, 26, 27, and 28 — reflecting the legacy safeguard structure. Use official numbers, not simplified sequencing.

Country-Specific Quotas
The measure allocates quotas by country for major steel-exporting nations, with a residual pool for all others:
- European Union — largest quota holder across most categories
- India — significant allocations in Categories 1, 4, and 13
- South Korea — allocations across Categories 1, 4, 5, 6, 7, 15, and 17
- Vietnam — major allocation in Category 4 (metallic coated sheets)
- Turkey — allocations in Categories 12B and 13 (rebars)
- United States — smaller allocations in Categories 7, 14, and 17
Once a country’s quarterly quota for a category is exhausted, all further imports from that country in that category face the 50% tariff — even if other countries’ quotas remain open. HMRC administers access on a “first come, first served” basis. Importers must cite the relevant quota order number on their customs declaration.
Category 1 Authorised Use
Category 1 (hot-rolled sheets and strips) has a special authorised use provision for importers who process steel into downstream products. Key rules:
- 40% country cap — no single country can supply more than 40% of the total Category 1 authorised use quota per quarter
- Single global quota — once exhausted, 50% duty applies regardless of country caps
- Processing within 12 months — goods must be transformed into specified downstream products (cold-rolled sheets, coated sheets, tin mill products, pipes, tubes)
- HMRC authorisation required — under the Customs (Special Procedures and Outwards Processing) (EU Exit) Regulations 2018
The authorised use pool is roughly 2.4 million tonnes per year versus approximately 467,000 tonnes for the standard Category 1 quota. For importers who both process and trade Category 1 steel, the administrative overhead is worth it.
Transitional Exemption: 30 September Deadline
Goods under contract before 14 March 2026 and imported between 1 July and 30 September 2026 are fully exempt from the 50% out-of-quota duty.
To claim the exemption, importers must provide HMRC with a signed, binding contract dated before 14 March 2026 specifying quantity, price, and delivery terms. HMRC’s 2 June 2026 implementation notification makes clear that framework agreements, letters of intent, and verbal contracts do not qualify.
Importers relying on the exemption should:
- Gather evidence now — signed contracts, purchase orders, pre-14 March correspondence
- Calculate remaining volumes — how much contracted quantity is still to be imported before 30 September
- Prioritise shipments — goods with highest duty exposure cleared first
- Prepare for post-30 September — any volumes arriving after the deadline face the full measure
After 30 September, the exemption disappears entirely. There is no extension.
Impact by Importer Type
Steel stockholders and traders: Highest risk. Thin margins, high import dependence, limited ability to pass through 50% duty. Maximise transitional exemption usage before 30 September. Post-September, quota monitoring becomes a daily operational requirement.
Downstream manufacturers: Moderate risk. Category 1 processors can use the authorised use route. Manufacturers of specialised products with limited UK production may find quota less binding. The key risk is for commodity-grade steel where domestic alternatives exist at higher prices.
Construction buyers and contractors: Emerging risk. Steel packages for rebar, sections, tubes, plates, and railway material all fall within the measure. Fixed-price contracts signed before quota details were known may not account for 50% duty exposure.
Infrastructure projects: Strategic risk. Long lead times and specified steel grades may find domestic supply insufficient and import quota uncertain. The policy aims to protect domestic steel for infrastructure, but the quota system may constrain the projects it’s meant to serve.
What Importers Should Do Now
1. Verify commodity codes. Check every steel product against the official category list. A misclassified code means the difference between tariff-free entry and 50% duty. Use the HMRC Trade Tariff.
2. Map country exposure. For each category, identify origin countries and check dedicated quota allocations. Single-country dependency above 40% for Category 1 or 60% for others needs a diversification plan.
3. Monitor quota utilisation weekly. HMRC publishes exhaustion data on GOV.UK. Subscribe to updates. Your customs agent should track this too, but the financial exposure is yours.
4. Secure transitional exemption evidence. If you have pre-14 March 2026 contracts with volumes still to import, submit evidence to HMRC now. The 30 September deadline is hard.
5. Review Incoterms. EXW or FCA terms leave you carrying quota and duty risk. DDP transfers it to the supplier — expect a price adjustment. See our Incoterms guide. For duty calculation fundamentals, our UK import duty guide covers how ad valorem rates are applied.
6. Model the 50% scenario. Calculate landed cost if quota is exhausted. If that number makes the import unviable, you need a contingency — alternative country, domestic sourcing, or product redesign.
7. Consider bonded warehousing. Holding steel in bond and releasing at the start of a new quarter helps manage quota timing. Works best for importers with predictable demand and warehouse capacity. See our guide to customs warehousing procedures in the UK for how duty suspension works.

Key Takeaways
- The measure is live. Quotas are being drawn down. The transitional exemption closes on 30 September 2026. This is not a drill.
- Quota cut is 51%, not 60%. Early reporting overstated the reduction. The final figure matters for cost modelling.
- Unused quota rolls over within the quota year. Quarterly rollover is permitted. Year-end carry-forward is not.
- The transitional exemption is a full exemption — not a separate quota pool. But the evidence bar is high: framework agreements and verbal contracts won’t qualify.
- The UK-EU coordinated deal means both markets tightened simultaneously. EU quotas were cut by 47% to 18.3 million tonnes per year.
- Category 1 authorised use provides a larger quota pool (≈2.4m tonnes/year) for importers who process hot-rolled steel into downstream products.
- Country diversification is now a commercial necessity. Single-country dependency above 40-60% creates real duty exposure.
Frequently Asked Questions
Is the quota cut 51% or 60%?
The government’s official information note confirms the reduction is 51% compared to the previous steel safeguard measure. The 60% figure that appeared in early trade press was based on preliminary analysis and is not the final number. Use 51% for planning purposes.
Can I carry forward unused quota to the next quarter?
Yes, within the same quota year. Unused country-specific and residual quota rolls to the next quarter. It does not carry between quota years — any unused quota on 30 June expires.
What evidence does HMRC need for the transitional exemption?
A signed, binding contract dated before 14 March 2026 specifying quantity, price, and delivery terms. Framework agreements, letters of intent, and verbal contracts are not accepted. HMRC’s 2 June 2026 implementation notification provides full detail.
What happens after 30 September 2026?
The transitional exemption ends. All imports from 1 October 2026 face the full measure with no grandfathering, regardless of when contracts were signed.
Does the 50% tariff apply to the whole shipment or just the excess?
The 50% tariff applies to the full CIF value of any shipment that exceeds the applicable quota. If your quota allows 100 tonnes and you import 150 tonnes, the entire 150 tonnes faces 50% duty — not just the 50-tonne excess.
How do I access the Category 1 authorised use quota?
Apply to HMRC for authorised use procedure approval under the Customs (Special Procedures and Outwards Processing) (EU Exit) Regulations 2018. You must demonstrate that imported Category 1 steel will be processed into specified downstream products within 12 months. Processing times are currently 2-3 weeks.
