MSS Review Service

MSS data is the consolidation of import and/or export data submitted to HMRC on behalf of businesses by customs clearance agents. The MSS data is identified against EORI numbers declared at the time of import and/or export from the UK. 

MSS data is available from HMRC which allows detailed analysis of actual information submitted to HMRC on businesses behalf.

The review and analysis of the MSS data allows for ensuring customs compliance and identifying import tax saving opportunities.

We are approved to obtain and analyse this data on behalf of our clients, breaking down the technical data into meaningful interpretations. We review the following aspects and provide a detailed report for management reporting purposes:


  • Amount of customs duty and other import taxes paid 

  • Use of Free Trade Agreements

  • Understanding when preferential duty is not claimed

  • Use of customs reliefs 

  • Commodity code review 

  • List of agents involved in the declarations to HMRC

  • Any particular data elements as requested by businesses
