Duty management system and closing stock balance systems: risks

The key weakness of all duty management systems is that they are not maintained on a real time basis but rely on data transferred from commercial systems (usually overnight) for updating the next working day. With duty management systems the duty point and entry into records Entry In Declarants Records (EIDR) purposes on removal will occur at a point within the commercial system after which the goods have been removed.

There is a risk that validation by the duty management system will identify an irregular removal (for example, no valid import license or preference certificate held) after the goods have been released. The warehouse keeper must therefore have controls in place to prevent ineligible removals. It is also important that the stock module within the duty management system populates its stock account at the same time as the commercial system.
