The Finance Leader’s Blind Spot

In many organisations, the customs function sits quietly within supply chain or operations. It rarely appears on a CFO’s agenda unless something goes wrong. Day to day, leaders rely on their teams to manage it, often trusting assurances that everything is under control. 

But what if those assurances are based not on deep expertise but on overconfidence? What if the people managing customs processes don’t have the necessary skillset, experience, or qualifications to recognise the gaps? 

This isn’t about negligence. It’s about a well-documented cognitive bias. In 1999, David Dunning and Justin Kruger identified what became known as the Dunning-Kruger Effect, a tendency for those with low ability in a given area to overestimate their competence. 

“People tend to hold overly favourable views of their abilities in many social and intellectual domains.”

In customs, this means people may believe their work is fully compliant, not because it is, but because they lack the technical depth to see the issues. 

Behind the Culture of “Everything is Fine” Lies Hidden Risk

When team members believe they have everything covered, leaders can be lulled into a false sense of security. In some cases, this can even create a culture of gatekeeping, where processes aren’t reviewed or challenged because doing so might expose errors. 

Statements like “we’ve always done it this way” or “there’s nothing to worry about” can mask significant weaknesses, including: 

• Misclassification of goods over many years.
• Incorrect valuation methods inflating duty paid. 
• Poor or missing origin evidence. 
• Incomplete or disorganised customs records. 

From a finance perspective, these aren’t just process issues. They are contingent liabilities in waiting, risks that may sit unnoticed for years until HMRC takes a closer look. 

Why Finance Leaders Must Act Now

Customs compliance isn’t static. Post-Brexit changes, new trade agreements, and HMRC’s increasingly data-led approach mean the risk environment is evolving. A team without independent oversight for years may not be equipped to keep up. 

For CFOs and FDs, the danger lies in: 

• Unknown exposure: Errors can go undetected for years, building into significant backdated liabilities. 
• Missed recoveries: Overpayments may never be reclaimed because no one is looking for them. 
• False confidence: Leadership decisions are made on the assumption compliance is robust when it may not be. 

The Critical Role of Independent Scrutiny

The solution isn’t about undermining trust in your team – it’s about protecting the business.  An independent customs review can:

• Validate existing processes and highlight strengths.
• Identify and quantify hidden financial risk.
• Uncover reclaim opportunities that strengthen working capital.

This is not a sign of failure. It safeguards against the blind spots that even capable, well-intentioned teams can miss.

Customs compliance risk often hides behind a culture of “everything is fine.” For finance leaders, the real question isn’t whether your team works hard – it’s whether they have the specialist expertise to see the whole picture.
