The Hidden Power of Customs Management in Global Trade

As global trade becomes more fragmented and unpredictable, managing customs properly has become a critical strategic capability for lowering costs and speeding time to market.

This article was developed in collaboration with Boston Consulting Group.

Customs management has long been treated as a necessary administrative function—complex, technical, and often delegated to large external brokers or local specialist providers in what used to be a relatively stable environment. For many companies, it’s managed quietly in the background, far from senior executive decision-making.

This mindset is no longer tenable. According to data from the World Trade Organisation, the World Bank, and UNCTAD, customs authorities levied an estimated $600 billion to $900 billion in tariffs in 2024. That’s almost 1% of global GDP, a figure that could double as trade tensions rise. Meanwhile, global trade is becoming more fragmented and less predictable, rules of origin for products traded around the world are tightening, and carbon-related border measures and sanctions are expanding.

These forces are not new, but the frequency of their fluctuations is accelerating, and their operational impact has become increasingly material, even as companies face growing pressure to improve margins, respond faster to market shifts, and manage geopolitical risk.

In this context, customs management is emerging as not simply a regulatory hurdle but a material driver of performance. When embedded into sourcing, product design, supply chain management, and planning decisions, customs considerations can reduce landed costs, accelerate time to market, and build resilience against disruption. Companies that act now to reframe customs management as a more strategic capability can gain a real competitive edge.

BCG recently partnered with Customs Support Group, a leading European customs broker, to explore current industry trends based on CSG’s experience working with European import/export companies and the steps companies are taking to introduce new customs management practices. We outline the hidden costs of inefficient customs operations, present five strategic levers to unlock value, and define five organisational enablers that support long-term transformation.

From Cost Burden to Business Lever

The current global trade environment, and especially sanctions and compliance issues, is putting increasing pressure on all companies that move goods across international borders. As the results of a recent survey show, only geopolitical disruption tops customs compliance as a critical challenge for European importers and exporters. (See the exhibit.)

Among the issues is cost visibility. Because customs costs are fragmented across logistics, tax, legal, and finance, they are hard to measure, typically underestimated, and rarely visible as such in the P&L. But they are significant—and damaging to competitiveness. Among the causes:

• Delays. Customs clearance times in Europe average between two and three days, according to World Bank and UN estimates. Clearance delays drive up inventory costs and, in the case of perishables, can result in missed sales or complete write-offs, particularly for cold-chain shipments of pharmaceuticals or produce.
• Errors. Preventable classification and documentation mistakes cause 20% to 40% of shipment delays, judging from the experience of customs brokers.
• Fees. Demurrage and detention fees charged to shippers for container storage often exceed several thousand dollars per container, depending on location and commodity.
• Penalties. Retroactive documentation audits by customs authorities can generate up to ten years of customs fee corrections, with added interest and fines.
• Missed Recovery. Duty overpayments due to the underutilisation of free trade agreements (FTAs) or misclassification of products routinely reach seven figures annually for global importers.

Rather than continuing to simply bear the many hidden costs of customs, leading companies are treating customs compliance as a strategic capability. By building customs considerations into their sourcing platform, for example, procurement teams can see in real time how the origin of materials and components affects landed costs under different agreements. This strategy results in substantial reductions in average duties paid on sourced components—around 10% less in the case of one global OEM.

Rather than continuing to simply bear the many hidden costs of customs, leading companies are treating customs compliance as a strategic capability.

Companies that have integrated their customs activities into sourcing, design, and planning have benefited in four ways:

• Margin protection through better product classification and reductions in trade agreement duties and taxes
• Speed to market via pre-submission of customs paperwork and simplified customs clearance processes
• Risk reduction through fewer adverse audit findings and less rework of customs declarations due to mistakes, customs questions, and other issues
• Operational agility amid sourcing shifts, regulatory changes, and trade disruptions

The difference between leading companies and others can be significant. For example, a recent client paying about $100 million annually in duties and taxes to import industrial equipment in Europe generated cost savings of around $5 million through better customs management. This was the result of more accurate product classification leading to lower duties and taxes, reduced fines and noncompliance penalties, more automated processes driving more consistency and productivity, and faster turnaround, which generated working capital savings. The company’s reinforced customs capabilities have also been instrumental in improving its resilience in the face of disruption, providing increased transparency and enabling it to rapidly optimise costs following changes in its supply chain configuration.

Five Strategic Levers to Unlock Value

Across industries, five strategic levers have emerged as critical to unlocking value from customs management, not just by reducing costs but through greater speed and resilience and better decision-making.
