Proposed quota reductions and tariffs could have significant implications for costs, supply chains and competitiveness across UK manufacturing.

There are significant changes on the horizon for UK manufacturers, and many businesses are now assessing what the potential impact could mean for their operations, supply chains and long-term competitiveness.

From 1 July 2026, the Government is proposing changes to steel import quotas that would reduce tariff-free allowances by around 60%. Under the proposals, steel imported above the allocated quotas would be subject to a 50% tariff.

The measures form part of a wider strategy to support domestic steelmaking. However, concerns are growing among manufacturers, steel stockholders and industry bodies about the potential consequences for businesses that rely on imported material.

In response, manufacturers across the UK have begun gathering support for a parliamentary petition calling on the Government to review the proposed measures before they come into force.

The petition calls for:

• A review of the proposed 60% quota reduction
• Reconsideration of the proposed 50% tariff rate
• A review of affected steel categories
• Further consultation with UK manufacturers

If the petition reaches 10,000 signatures, the Government must provide a formal response. At 100,000 signatures, it may be considered for debate in Parliament.

For many engineering and manufacturing companies, certain specialist grades of steel are either unavailable or not produced in sufficient quantities within the UK. As a result, the proposed changes could lead to increased material costs, reduced availability, supply chain disruption and additional pressure on competitiveness.

Manufacturers have also warned that the impact may extend far beyond individual businesses. Rising costs and material shortages could place additional pressure on supply chains, affecting engineering, manufacturing and industrial businesses that rely on a stable and competitive supply of steel.

With the proposals currently under discussion, now is the time for manufacturers to assess how the changes could affect their business and consider whether they wish to contribute to the ongoing debate.
