Customs Compliance Health Check: How to Assess Your Import Risk

Customs Compliance Health Check: How to Assess Your Import Risk

When did you last review your customs declarations for errors? Benchmarks from over 190 UK organisations show that 17% of UK import declarations contain mistakes, and 14% of duty value is often overpaid. A structured health check helps you uncover these issues before HMRC does.

What Is a Customs Compliance Health Check?

A customs compliance health check is a systematic review of your import declarations to identify:

• Classification errors and inconsistencies
• Valuation mistakes and overpayments
• Missed origin preferences and documentation gaps
• Incorrect customs procedure codes and missed reliefs
• Weaknesses in your documentation and audit trail

The goal is to focus on high-impact areas where errors are common and financial exposure is greatest.

Area 1: Classification Accuracy

Commodity classification is the foundation of customs compliance. Errors here drive incorrect duty rates, origin treatment, and trade statistics.

Key checks:

• Verify your commodity codes against the UK Trade Tariff.
• Review your top 20 commodity codes by volume and value.
• Look for classification drift over time (same product, different codes).
• Check for inconsistencies across sites, systems, and brokers.

Risk indicators:

• Multiple codes used for the same product family
• Frequent manual overrides of system-assigned codes
• Lack of written classification decisions or binding rulings

Area 2: Valuation Methodology

Customs value errors directly affect the duty you pay. Many importers either overpay or underpay because their valuation method is not applied correctly.

Key checks:

• Confirm the valuation method used (typically Transaction Value).
• Test sample entries to ensure the customs value calculation is correct.
• Identify non-dutiable charges that may have been incorrectly included, such as:
• Post-importation inland freight
• Certain buying commissions
• Post-import installation or construction costs
• Check for dutiable additions that may be missing, such as:
• Assists (design, tools, moulds supplied free or at reduced cost)
• Royalties and licence fees related to the imported goods
• Certain commissions and packing costs

Risk indicators:

• Same Incoterms but different valuation treatments
• No documented valuation policy or methodology
• Inconsistent treatment of freight, insurance, and surcharges

Area 3: Origin and Preference Utilisation

Preferential origin can significantly reduce your duty bill, but only if you use it correctly and keep robust evidence.

Benchmarks show that the average UK textile importer has a 53% preference utilisation gap – meaning more than half of eligible imports do not benefit from available preferences.
