BM Catalysts highlights potential aftermarket impact of new UK steel trade measures

BM Catalysts, Europe’s leading manufacturer of aftermarket hot end emissions products, is urging policymakers to consider the broader implications of the UK’s forthcoming steel trade measures on manufacturing and automotive aftermarket supply chains.

The Government has confirmed that, from 1 July 2026, tariff-free steel import volumes will be significantly reduced, with imports exceeding quota levels subject to a 50% tariff. While the intention is to strengthen domestic steel production and address global market pressures, businesses operating in highly specialised manufacturing sectors face a number of practical considerations.

Headquartered in the UK, BM Catalysts manufacture and supply the UK and European aftermarket with an extensive range of catalytic converters (CATs), diesel particulate filters (DPFs) selective catalytic reduction (SCR) units and gasoline particulate filters (GPFs) as well as front and connecting pipes. As a business built on quality, performance and compliance, BM Catalysts relies on carefully specified raw materials that meet the technical demands of modern emissions control systems.

A key example is 409-grade stainless steel, which is used extensively in the production of exhaust and emissions control components due to its heat resistance, durability and suitability for automotive applications. The material has long been the industry standard for hot end exhaust products, helping manufacturers deliver reliable products capable of withstanding the extreme operating conditions found within vehicle exhaust systems.

For specialist manufacturers, maintaining consistent access to these materials is essential. Any disruption to supply, reduced availability or significant increase in procurement costs has the potential to create knock-on effects throughout the automotive aftermarket.

These impacts could include increased manufacturing costs, extended lead times and greater pressure on inventory planning, all of which may ultimately affect the competitiveness of UK manufacturers serving both domestic and export markets. Businesses across the supply chain may be required to absorb additional costs, reassess sourcing strategies or delay investment decisions while adapting to changing market conditions.

The automotive aftermarket is a vital contributor to the wider economy, supporting vehicle maintenance, emissions compliance and consumer choice while sustaining thousands of jobs across manufacturing, distribution and independent garages. The sector depends on resilient supply chains and the ability to source specialist materials that are not always readily available from domestic producers.

As discussions around implementation continue, BM Catalysts believes that ongoing engagement between government and manufacturing stakeholders will be essential to ensuring the UK’s industrial strategy supports the entire value chain. A balanced approach can help safeguard domestic capability, maintain supply chain stability and protect the businesses that underpin the UK’s world-class manufacturing and automotive aftermarket sectors.
