Preparing for a Customs Audit using Real Customs Data

Did you know that in a customs audit, the HMRC holds records of actual data entered and assesses duties for imports based on what is actually declared to customs, not what is in the trader’s own records?

When a customs audit takes place, HMRC holds records of actual data entered and raises demand on duties for imports not recorded in the trader’s records but actually declared to customs

HM Revenue & Customs

Do you trust that your records are up to date and match the HMRC’s data? Are you sure the customs broker or freight agent entered the correct information on your declarations?

“A significant proportion of companies we talk to don’t receive customs declarations from their brokers, and even those who do often don’t conduct self-audits on an adequate sample of declarations to uncover mistakes”, Mark Jamieson, VP of Operations at Emma Systems UK says.

Human errors are likely to occur when making customs declarations.  Common errors include using the wrong:

  • Currency
  • Country of origin
  • Customs Procedure Code
  • Tariff number /Commodity Code

Do you check and verify that the customs broker or freight agent in fact entered the right information on your declarations? In the end, you are responsible for the declarations, regardless of if you use brokers or agents for making the declarations.
