Beyond Brexit: How trade policy continues to shape UK supply chains

Beyond Brexit: How trade policy continues to shape UK supply chain

While the initial disruption may have settled, trade policy continues to evolve. New trade agreements, changing tariff rules, updated border controls and shifting geopolitical relationships continue to influence how organisations source products, manage suppliers and move goods across international markets.

Five years on, success is no longer determined solely by finding the lowest-cost supplier or the quickest shipping route. Organisations also need to understand customs requirements, preferential tariffs, rules of origin and evolving regulatory obligations.

For procurement, supply chain and logistics leaders, keeping pace with these developments has become part of everyday business.

 

Brexit changed the rules. Trade policy continues to reshape them.

The UK-EU Trade and Cooperation Agreement (TCA) provided tariff-free and quota-free trade for goods that meet the relevant rules of origin. However, leaving the EU Single Market and Customs Union introduced customs declarations, additional documentation and new regulatory requirements that continue to influence cross-border trade.

Rather than adapting to a single change, organisations have found themselves navigating an environment where trade policy continues to evolve.

The introduction of the Border Target Operating Model (BTOM) has gradually reshaped import processes, while ongoing discussions between the UK and EU aim to simplify trade in areas such as food, plants and animal products through a future Sanitary and Phytosanitary (SPS) agreement. These developments have the potential to reduce administrative burdens, but they also require organisations to stay informed and adapt their processes accordingly.

Research from The Productivity Institute found that UK exports to the EU declined significantly in the years following Brexit, with many organisations facing higher administrative costs and increased non-tariff barriers. While trade volumes continue to recover across some sectors, customs compliance remains a permanent part of trading with Europe.

For importers and exporters, understanding trade policy is no longer a specialist consideration. It has become an operational necessity.

 

Trade agreements create opportunity, but they also create complexity

As the UK continues to develop independent trade relationships around the world, new opportunities are emerging for organisations looking to diversify their markets and supply chains. Recent agreements with countries including India and Switzerland aim to reduce tariffs, improve market access and strengthen commercial relationships across a range of sectors.

On paper, lower tariffs present an obvious commercial advantage.

In practice, benefiting from these agreements requires organisations to understand the detailed rules that sit behind them.

Preferential tariffs often depend on rules of origin, which determine where a product has been manufactured or substantially transformed. Organisations must be able to demonstrate compliance through the correct documentation and supplier evidence before claiming reduced duty rates.

This means procurement decisions increasingly involve more than negotiating price and lead times.

Businesses also need to consider:

• Whether suppliers meet origin requirements.
• How products are classified under customs rules.
• Whether changing suppliers could affect tariff eligibility.
• The documentation required to support international shipments.

Trade agreements can unlock significant commercial benefits, but only when organisations have the processes and expertise needed to use them effectively.

 

Tariffs continue to influence sourcing strategies

Alongside new trade agreements, changing tariff policies continue to shape global sourcing decisions.

Recent US tariff measures, alongside wider geopolitical uncertainty, have added another layer of complexity for organisations operating internationally. Even where UK exporters are not directly affected, global tariff changes influence supplier pricing, manufacturing locations and the movement of raw materials across international markets.

Procurement teams are therefore assessing suppliers through a much broader lens than they did a few years ago. Cost remains important, but it now sits alongside considerations such as tariff exposure, regulatory compliance, geopolitical stability and supply chain resilience.

As a result, many organisations are diversifying their supplier base, reviewing sourcing locations and reducing reliance on individual countries or trade routes.

Supply chains are becoming more strategic, with long-term resilience carrying greater weight in commercial decision-making. We're seeing these considerations become part of everyday procurement discussions, rather than issues that only arise when disruption occurs.

 

Logistics has become more than moving goods

Trade policy has also changed the way logistics teams operate.

Moving products internationally now requires far greater visibility across customs procedures, documentation and border requirements than many organisations experienced before Brexit.

Importers and exporters must consider customs declarations, commodity codes, origin documentation, safety and security requirements, product-specific regulations and changing border processes.

Errors can lead to delays, unexpected duty costs and disruption throughout the wider supply chain.

At the same time, wider global events continue to influence logistics planning. Geopolitical tensions, changing shipping routes and capacity constraints have encouraged organisations to build greater flexibility into their operations through diversified transport options and improved supply chain visibility.
The ability to respond quickly has become just as valuable as efficiency.

 

Expertise is becoming a competitive advantage

As trade policy becomes more dynamic, organisations are recognising that compliance is no longer simply an administrative task.

Understanding tariffs, customs procedures and international trade agreements directly influences sourcing decisions, operational efficiency and commercial performance. From our conversations with employers, we're seeing greater demand for professionals who understand international sourcing, customs compliance and cross-border logistics alongside their wider procurement or supply chain responsibilities.

These are the people who can help organisations interpret changing regulations, identify opportunities within new trade agreements and reduce unnecessary costs throughout the supply chain.
As trade rules continue to evolve, that expertise is becoming increasingly valuable.

 

Looking ahead

Trade policy is unlikely to stand still.

The UK continues to develop new international trade relationships while refining existing agreements with key trading partners. At the same time, global tariff policies, geopolitical developments and regulatory changes will continue to influence sourcing decisions and logistics strategies. For organisations, success will depend on remaining agile.

Regularly reviewing sourcing strategies, understanding how trade agreements affect commercial decisions and building the right expertise within procurement, supply chain and logistics teams will all play an important role in navigating the years ahead.

Post-Brexit trade is no longer about adjusting to a single event. It's about responding confidently to a trading environment that continues to evolve.

The organisations that adapt most successfully won't simply be the ones responding to change. They'll be the ones preparing for it.
