Fear, Avoidance, and Customs Compliance: What CFOs Should Know

For most CFOs, customs compliance sits in an uncomfortable grey area. It is not quite logistics, not quite tax, and rarely appears on the finance team's dashboard. Yet the financial consequences of getting it wrong are entirely a CFO's problem: retrospective duty assessments, penalties, and lost reclaim opportunities all hit the bottom line.

So who actually owns customs strategy in your organisation? In many businesses, the honest answer is nobody at board level. Declarations are outsourced to brokers, operational teams handle day-to-day imports, and finance only gets involved when something has already gone wrong. That gap in oversight is where the real risk lives.

Post-Brexit Customs Reality

Since the UK left the EU single market, every shipment crossing the border now requires a customs declaration. The UK collects approximately £5.5 billion in customs duties annually, and HMRC has significantly increased its audit and compliance activity to protect that revenue.

For businesses that previously traded freely within the EU, this represents an entirely new compliance burden. Many organisations stood up processes quickly in 2021 and have not revisited them since. The result is a patchwork of workarounds, inconsistent classification approaches, and reliance on brokers who were onboarded under pressure.

HMRC's post-Brexit enforcement posture is more assertive than many CFOs realise. Retrospective assessments can cover up to three years of declarations, and where HMRC identifies deliberate non-compliance, that window extends further. The financial exposure from even routine classification errors, compounded across thousands of declarations, can be substantial.

The Cost of Not Looking

There is a pattern that appears repeatedly in organisations with customs compliance gaps: leadership suspects there may be problems but deliberately avoids investigating. This behaviour has a name in behavioural psychology — FOFO, or the Fear Of Finding Out.

The reasoning is understandable. If you commission a review and discover errors, you may feel obligated to disclose them. If you do nothing, perhaps the issue will never surface. But this logic is flawed for two reasons.

First, HMRC's data capabilities have improved considerably. Cross-referencing CDS declarations with trade statistics, supplier data, and sector benchmarks means anomalies are increasingly likely to be flagged automatically. Second, once HMRC initiates formal proceedings, the option for voluntary disclosure — which typically results in more favourable treatment — narrows significantly or disappears altogether.

Proactive review almost always produces a better financial outcome than waiting for an investigation. Identifying overpayments early can generate reclaims. Identifying underpayments early allows for managed disclosure rather than enforced penalties.

Third-Party Reliance Is Not Risk Transfer

Most UK importers use customs brokers to submit declarations on their behalf. This is entirely normal and often operationally necessary. However, many CFOs assume that outsourcing declarations also transfers the compliance risk. It does not.

Brokers process declarations based on the information provided to them. They apply commodity codes, calculate duty, and submit to HMRC. But they are working from the data your organisation supplies — product descriptions, values, country of origin. If that underlying information is inaccurate or incomplete, the declaration will be wrong regardless of how competent the broker is.

Critically, legal liability for the accuracy of customs declarations rests with the importer, not the broker. Errors in classification, valuation, or origin determination can trigger retrospective duty assessments that fall squarely on your balance sheet. Most broker contracts contain limitation of liability clauses that cap their exposure at a fraction of potential losses.

This is not an argument against using brokers. It is an argument for verifying the accuracy of what they submit and ensuring that your internal data feeds are fit for purpose.

The Psychology Behind Inaction

Understanding why senior leaders avoid engaging with customs compliance requires looking at the behavioural drivers at work. Three psychological patterns are particularly relevant.

Loss aversion means that the prospect of uncovering a liability feels more painful than the potential benefit of finding a reclaim opportunity. Even when the expected value of a review is positive, the emotional weight of possible bad news keeps decision-makers from acting.

Cognitive dissonance arises when leaders who pride themselves on rigorous financial governance simultaneously acknowledge that they have no visibility over a multi-million-pound area of spend. Rather than confronting that gap, it is easier to rationalise it: the broker handles it, logistics owns it, it has never been a problem before.

Avoidance behaviour is the natural consequence. When a topic feels unfamiliar and potentially threatening, the default response is to deprioritise it. Customs compliance rarely makes the board agenda because nobody wants to be the person who opens a difficult conversation without a clear solution in hand.

A Real-World Example

Consider a UK retailer importing consumer goods across multiple product categories. For over two years, their broker applied commodity codes based on broad product descriptions provided by the buying team. Nobody within the business verified whether those codes were correct.

When the issue was eventually identified, it became clear that a significant proportion of goods had been misclassified. Some codes attracted higher duty rates than necessary, meaning the business had overpaid by hundreds of thousands of pounds. Other codes were too low, creating an underpayment liability.

The overpayments could have been reclaimed — but HMRC allows reclaims only within a specific window. By the time the errors were discovered, much of that window had closed. The underpayments still required correction and disclosure. The net financial impact was significant, and entirely avoidable had the business implemented even basic verification processes.

Questions Every CFO Should Ask

If customs compliance has not been on your agenda, these questions provide a starting point for understanding your organisation's exposure:

• Are our customs declarations regularly audited or reviewed internally? If the answer is no, you have no assurance that what is being declared to HMRC is accurate.
• Do we have a documented process for commodity classification, origin determination, and customs valuation? These three areas account for the majority of compliance errors and financial exposure.
• What is our total customs duty under management? Many CFOs cannot answer this question, which makes it impossible to assess materiality or prioritise resources.
• What contractual assurances do we have from our customs brokers? Understanding liability caps, error correction procedures, and service level commitments is essential.

Building Internal Controls

Bringing customs compliance within the scope of financial governance does not require building a large in-house team. It does require establishing basic controls and accountability structures.

Periodic reviews of declaration data should be built into the compliance calendar. Quarterly spot-checks on commodity codes, duty rates, and valuation methods can catch systemic errors before they compound.

Accountability clauses in broker contracts should be reviewed and, where necessary, strengthened. Brokers should be required to demonstrate how they verify the information provided to them and what quality assurance processes they apply.

Independent audits every three to five years provide a deeper level of assurance. External customs specialists can benchmark your declarations against sector norms, identify reclaim opportunities, and flag areas of risk that internal teams may lack the expertise to spot.

The goal is not to duplicate the broker's work. It is to create a verification layer that gives the CFO and the board confidence that customs spend is accurate and compliant.

Technology as an Enabler

One of the barriers to CFO engagement with customs has traditionally been the complexity of the data. Tariff codes, trade agreements, valuation rules, and origin protocols are specialist domains. Expecting a finance leader to interpret raw CDS data is neither realistic nor efficient.

This is where technology changes the equation. CAT360 is designed to give finance and leadership teams visibility over customs data without requiring deep technical expertise. The platform ingests declaration data, identifies anomalies, flags reclaim opportunities, and highlights compliance risks — all presented in a format that a CFO can act on.

Rather than commissioning a lengthy manual review, CAT360 enables continuous monitoring. Errors are surfaced in near real-time rather than discovered months or years after the fact. Reclaim windows are tracked so opportunities are not lost. And compliance posture is quantified, giving the board a clear picture of risk exposure.

Customs compliance does not need to remain a blind spot in financial governance. The data exists, the tools to analyse it are available, and the financial case for action is compelling. For CFOs willing to look, the rewards — in recovered duty, reduced risk, and stronger operational control — far outweigh the discomfort of confronting what they might find.
