From 1 July 2026, the UK government is replacing its steel import safeguard measure with a tighter tariff-rate quota system. Tariff-free import volumes will fall by 51% across 20 steel product categories. Any steel imported above those reduced thresholds will face a 50% duty, up from 25% under the previous measure. Transitional relief is available for goods contracted before 14 March 2026.
The rules governing steel imports into the UK changed significantly on 1 July 2026. For businesses that rely on cross-border steel supply chains, this is not background noise. It is a direct commercial pressure that will affect landed costs, customs planning, and purchasing decisions if you have not already prepared. This post breaks down what the new measure means in practice, where the biggest pressure points are, and how you can stay on the front foot.
What has changed and why
On 19 March 2026, the UK government announced a new steel trade measure, which takes effect from 1 July 2026. It replaces the previous steel import safeguard regime, which expired on 30 June 2026.
The policy is a direct response to sustained global steel overcapacity. According to the Organisation for Economic Co-operation and Development (OECD, 2025), the gap between global steel capacity and demand is expected to reach 721 million metric tonnes by 2027, equivalent to 13% more than the current total production capacity of all OECD member countries. Against that backdrop, UK crude steel output has declined by more than 50% over the past decade, falling from 10.9 million metric tonnes in 2015 to four million metric tonnes in 2024 (World Steel in Figures, 2025).
The government has positioned the new measure as a core component of its broader UK Steel Strategy, aimed at protecting domestic steelmaking capacity in sectors including defence, energy, and transport infrastructure.
Key changes at a glance
- Quota volumes reduced by 51% compared with the previous steel import safeguard measure
- Out-of-quota tariff doubled to 50%, up from 25% under the safeguard measure
- 20 steel product categories are in scope, covering products that can be manufactured domestically in the UK
- Quarterly tariff-rate quota system, operating on a first-come, first-served basis, managed by HMRC
- Quota periods: Q1 (1 July to 30 September), Q2 (1 October to 31 December), Q3 (1 January to 31 March), Q4 (1 April to 30 June)
- Unused quota rolls over to the following quarter but not into the next quota year
- Ukraine is excluded from the measure; existing preferential tariff arrangements under the UK-Ukraine Political, Free Trade and Strategic Partnership Agreement remain in place
If your steel products do not fall within the 20 defined categories, no quota applies and no additional tariff will be charged. Checking whether your commodity codes fall within scope should be your first step.
What this means in practice for importers
The commercial impact is straightforward: lower quotas mean duty-free volume disappears faster. Once a quota is exhausted, every tonne above that threshold attracts a 50% duty on the value of the goods. For high-volume importers, that creates real cost exposure. For businesses with time-sensitive shipments arriving near quarter boundaries, there is an added risk of landing in a depleted quota period. Downstream industries, including manufacturing, construction, and infrastructure, will also feel indirect effects as increased costs pass through supply chains.
Sourcing strategies that worked under the previous regime may no longer deliver the same commercial outcomes. Pricing mechanisms in existing contracts may not reflect the new duty levels. Both areas are worth reviewing now, if you have not already done so.
Key areas to plan around
How quickly could quotas run out?
Because access is first-come, first-served, quota availability in each quarter is not guaranteed. Early-quarter shipments from countries with smaller individual allocations, particularly residual-category volumes, may exhaust their quota faster than expected. Monitoring quarterly utilisation rates will become a routine part of import planning, not an afterthought.
Timing your declarations carefully can make a material difference to whether you land inside or outside the quota threshold.
Temporary storage and customs processes
With tighter quota windows, the gap between when goods arrive and when they are declared becomes commercially significant. Using bonded warehousing or temporary storage facilities strategically can give you more flexibility in timing your customs entries to align with available quota.
Our customs teams can support you in managing this process, from pre-arrival planning to declaration timing and storage coordination.
Real-time visibility of customs declarations
Knowing where you stand against available quota, in real time, is essential under the new regime. Delays in customs declaration processing or gaps in visibility could result in inadvertently importing out-of-quota and triggering the 50% duty unexpectedly.
We provide real-time visibility of customs declarations so you can track your position accurately and act quickly when quota levels tighten.
Scenario planning for high-volume or time-sensitive imports
For businesses with significant steel volumes or contracts that span quarter boundaries, scenario planning is worthwhile. That means modelling what happens to your landed costs if quota is exhausted before your shipment clears, and identifying which product categories carry the highest exposure.
If you are moving large volumes across multiple quarters, forward planning with your freight and customs teams can reduce the risk of unexpected duty costs.
Transitional arrangements: what you need to know
A time-limited transitional arrangement is available for businesses with qualifying contracts. Goods contracted before 14 March 2026 are fully exempt from the 50% out-of-quota duty between 1 July 2026 and 30 September 2026.
To benefit, you will need to provide evidence of eligibility to HMRC. The government has confirmed that enforcement action will be taken where cases of non-compliance or deliberate fraud are detected.
If you have relevant contracts and have not yet assessed whether they qualify, the window to act is short.

Frequently asked questions
What is the UK steel trade measure that takes effect on 1 July 2026?
The UK government's new steel trade measure replaces the previous steel import safeguard regime, which expired on 30 June 2026. From 1 July 2026, tariff-free import volumes for steel are reduced by 51% across 20 product categories. Imports above the reduced quota thresholds attract a 50% out-of-quota tariff, up from 25% under the previous measure. The measure is implemented under the Taxation (Cross Border Trade) Act 2018.
Which steel products are affected by the new UK quota system?
The measure covers 20 steel product categories, defined by specific commodity codes. The scope focuses on products that can be manufactured domestically in the UK. Products not listed within those 20 categories are not subject to any quota or additional duty. If you are unsure whether your products fall within scope, checking your commodity codes against the government's published list is the first step.
How does the first-come, first-served quota system work?
HMRC administers access to the duty-free quota on a first-come, first-served basis. Importers must cite the relevant order number when applying to access a specific quota. Quota is allocated quarterly and unused volumes roll over to the next quarter. However, unused quota does not carry across to the following quota year.
Are goods from Ukraine subject to the new steel trade measure?
No. Ukraine is excluded from the new measure. Existing preferential tariff arrangements under the UK-Ukraine Political, Free Trade and Strategic Partnership Agreement remain in place, subject to compliance with preferential rules of origin set out in that agreement.
What is the transitional arrangement and who qualifies?
Goods that were under contract before 14 March 2026 are fully exempt from the 50% out-of-quota duty between 1 July 2026 and 30 September 2026. Evidence of eligibility must be provided to HMRC. The transitional arrangement does not extend beyond 30 September 2026.
What happens if a quarterly quota is exhausted before my shipment arrives?
If the relevant quota has been used up, your import will be subject to the 50% out-of-quota tariff on the full value of the goods before any other import duties are applied. This makes shipment timing and declaration management critical, particularly for high-volume importers or shipments that arrive near quarter-end dates.
