Your End-of-Year Customs Compliance Checklist

The end of the year is one of the few natural pause points in international trade. The Christmas rush is over, volumes are winding down, and businesses have a rare opportunity to take stock of what is and isn’t working.

With the new year often bringing in changes in regulations, HS codes, and trade agreements, it is also the ideal moment to take a step back and assess your customs compliance. This doesn’t need to be a formal audit, but a structured review can quickly identify where your strengths, weaknesses, opportunities, and risks are.

This end-of-year customs compliance checklist provides a practical, skimmable sense check so that you can focus on the areas most likely to create exposure in the future.

Contents:

• Classification and valuation
• Origin and preferential trade
• Licences, permits, and authorisations
• Sanctions and export controls
• Digitalisation and data quality
• Documentation and record keeping
• Outstanding reclaims and financial optimisation
• Internal governance and accountability
• Training and internal resource
• Broker and supply chain oversight
• Turning insight into advantage

Classification and Valuation

Are your customs fundamentals still correct and defensible?

• Have you recently reviewed your commodity codes?
• Are your goods classification methods documented and consistently applied?
• Do you have any Binding Tariff Information that is up for renewal?
• Has your customs valuation been checked to ensure that it aligns with expected methods?
• Have you recorded and declared all required cost elements (freight, insurance, etc)?

Ask yourself: Where would a customs authority be most likely to challenge your data, and can you provide an acceptable answer?

Origin and Preferential Trade

Are preference claims accurate and supportable?

• Are your customs origin and preferential origin calculated correctly?
• Do you hold the correct supplier statements on the paperwork, or separately?
• Does your preferential origin still align with the relevant trade agreements?
• Is your origin data traceable and verifiable?

Ask yourself: What is your exposure if a key supplier declaration is withdrawn or invalidated?

Licences, Permits, and Authorisations

Are your permissions current and fit for purpose?

• Do you have any import or export licences up for renewal?
• Do your current operations align with the requirements under your authorisations (AEO, simplified declarations, deferment accounts)?
• Have you recently checked product-specific permits for regulatory updates?

Ask yourself: What operational impact would the temporary loss of a key authorisation have?

Sanctions and Export Controls

Are your export controls aligned with current geopolitical restrictions?

• Are sanctions and circumvention screening embedded into your workflows?
• Have you correctly identified all dual-use and controlled goods in your operation?
• Are the end-use and end-user checks documented?
• Have your processes recently been checked against regulatory or geopolitical changes?
• Are your staff trained to recognise and escalate queries with sensitive transactions?

Ask yourself: Which legacy products or markets have not been reassessed recently?

Digitalisation and Data Quality

Do your systems support your compliance, or create risk of complacency?

• Is your classification, origin and valuation data consistent across systems?
• Have you identified and mapped out manual interventions or workarounds?
• Are there clear audit trails from procurement to customs declaration?
• Is data easily retrievable for authority audit or internal review?
• Have you checked upcoming reforms or regulations to ensure you are prepared?

Ask yourself: Do you have complete visibility throughout a purchase or sale, and does data integrity depend on individuals rather than systems?

Documentation and Record Keeping

Could you respond confidently to a customs audit?

• Are all of your customs declarations, invoices, licences and certificates easily accessible?
• Is your recordkeeping aligned with your national retention requirements?
• Is there full traceability between your commercial and customs documentation?
• Do you periodically complete internal checks on data completeness and accuracy?
• Is there clear ownership of documentation management at each stage?

Ask yourself: How quickly could you produce evidence if authorities requested it tomorrow?

Outstanding Reclaims and Financial Optimisation

Have opportunities been missed?

• Have duty overpayments been identified and reclaimed where available?
• Are preferential origin opportunities reviewed retrospectively?
• Have you looked at reliefs such as inward processing or returned goods?
• Have you completed post-clearance corrections where required?

Ask yourself: Where could historic decisions still be impacting your overall spend today?

Internal Governance and Accountability

Is customs compliance clearly owned within your organisation?

• Is there clear ownership for classification, origin and valuation decisions?
• Do you have clear escalation policies for non-standard or high-risk transactions?
• Do you have documented internal customs policies and procedures?
• Is there visibility for senior management over customs risk and exposure?
• Do you periodically complete internal compliance reviews to review gaps in processes?

Ask yourself: If a senior customs or compliance specialist leaves or becomes unavailable, can a replacement quickly understand everything?

Training and Internal Resource

Do the right people understand their customs responsibilities?

• Have you provided role-specific customs training?
• Do your sales, procurement and finance teams have an understanding of the impact of their decisions on customs, and vice-versa?
• Do you have evidence of completed training?
• Do your onboarding processes include customs fundamentals?
• Do you often check for regulatory change and provide timely refresher customs training to those affected?

Ask yourself: Where could well-intentioned decisions create unintended compliance risk because of knowledge gaps?

Broker and Supply Chain Oversight

Can you rely on third parties without losing control?

• Is there a clear division of responsibility with external brokers?
• Do you regularly review partner processes and accuracy?
• Is your supplier-provided data validated and monitored?
• Do you have oversight of changes made by third parties on your behalf?
• Do you have escalation processes for recurring errors on either side?

Ask yourself: Could you demonstrate that sufficient due diligence processes were followed on your side if a broker error was challenged?
