Post-Entry Trade Audits

Post-entry trade audits are a crucial aspect of customs compliance and revenue protection for governments around the world. These audits involve reviewing and verifying the accuracy of import declarations, export documents, and other customs-related records to ensure that traders have accurately reported their goods and paid the correct duties.

The primary purpose of post-entry trade audits is to detect and prevent customs evasion, which can result in significant losses of revenue for governments. Customs authorities use a variety of techniques to identify high-risk shipments and select them for audit. These may include:

  • Data mining: analyzing large datasets to identify patterns or anomalies that may indicate customs evasion

  • Risk assessment: evaluating the likelihood of customs evasion based on factors such as the traders history, the type of goods being imported or exported, and the route taken by the shipment

  • Targeted sampling: selecting a random sample of shipments for audit in order to assess the accuracy of reported information


  • Once a shipment has been selected for post-entry trade audit, the customs authority will typically conduct an examination of the relevant records and documentation. This may involve:

  • Reviewing import or export declarations to ensure that they accurately reflect the goods being imported or exported

  • Verifying the origin of the goods to determine whether the correct duty rates have been applied

  • Checking for any discrepancies between the reported value of the goods and their actual value

  • Identifying any discrepancies between the declared and actual weight, volume, or other characteristics of the goods


  • If the audit reveals that customs evasion has occurred, the trader may be required to pay additional duties, penalties, and interest on the underpaid amount. In some cases, the trader may also face fines or even prosecution.

  • Transparency and cooperation: traders should be transparent and cooperative during the audit process, providing all requested information and documentation in a timely manner
