I have received numerous enquiries concerning the availability of the the WCO DMV3.

The WCO has since clarified that DMV3 will not be available in DVD format. The intitial release on DVD was merely to commemorate the launch, where each member customs administration received a  copy. 

Members of the private sector seeking access to this service will be able to view the contents of the data model exactly as it is presented in the DVD. The content will be updated from time to time. The cost of such service is Euro 980.00.

Admittedly this is quite an exhorbitant amount, but content includes eHandbook and ePrimer but also eSupport, a page that allows the user to provide feedback, ask queries and consult with the experts at the WCO. Trust this clarifies the situation.
