EMCS technical interface specification

Version 0.1 issued August 2023

Document summary

This document is the first part of the technical interface specification (TIS) for direct trader input (DTI) to Excise Movement and Control System (EMCS).

It shows the processes involved in the exchange of messages between traders and EMCS during excise movements, and provides definitions, formats and validations of those messages.


Excise Movement and Control System (EMCS) is a UK and EU-wide computer system that’s used to record duty suspended movements of excise goods taking place within the UK and the EU.

It allows the exchange of secure online messages containing specific consignment and movement information between UK and EU trading partners.

The TIS should be read with the following related documentation:
