Cross-border trade has become a supply chain management test for the whole island. Two Stormont-commissioned reports, covered by BBC News NI, find the Windsor Framework, agreed by the UK and EU in 2023, has brought greater stability but not yet simplicity. Economist Maureen O'Reilly describes a more predictable environment still marked by cumulative regulatory and compliance demands. For operational excellence leaders in Northern Ireland and the Republic, that is a clear brief.

The reports are better read as a roadmap than a warning. Stability is an achievement that lets businesses plan, and the remaining friction is largely administrative, which makes it addressable. Three themes stand out: supplier relationships, tariff clarity, and the practical use of dual market access.

Supplier relationships come first. O'Reilly found that GB suppliers continue to raise minimum orders, add administrative surcharges, or withdraw from supplying Northern Ireland entirely. Many firms have shifted sourcing to Ireland or the wider EU, often at greater cost. Trade consultancy Fortior Insight found that suppliers in many cases withdrew before fully understanding the simplifications available. Operational resilience through diversified sourcing, not exit, is the stronger response, and O'Reilly notes businesses continue to adapt.

Tariff clarity comes second. Fortior found confusion about the framework's "at risk" concept, which applies to goods that could move on to the Republic and so be liable for EU tariffs. It does not mean a product is substandard, yet public messaging has unintentionally made the label seem undesirable, though many legitimate commercial models rely on such declarations. Clear process improvement in how firms classify tariff status can remove that confusion quickly.

Dual market access comes third. O'Reilly found some firms beginning to exploit access to both UK and EU markets, though the overwhelming feedback is that administrative realities heavily constrain the benefit. A spokesperson said £16.6 million (approximately €19.9 million) will fund a new service offering simpler, tailored support for businesses moving goods to Northern Ireland, and an agri-food and drink deal with the EU is planned. Fortior also identified practical measures to reduce friction under existing arrangements.

Three practical steps follow. First, map supply chains by supplier and route, identify surcharge or withdrawal risk, and qualify alternative suppliers in Ireland and the EU. Second, train procurement and logistics teams on "at risk" declarations so that tariff status is understood as a commercial classification. Third, engage with the new support service as it launches to raise operational efficiency in moving goods.

The Stormont reports confirm that the Windsor Framework has delivered stability, with simplicity still to come. Firms across the island that strengthen their supply chains, clarify tariff processes, and use dual access deliberately will be well placed to turn a complex trading environment into competitive advantage.
