Web-based customs declaration management application used by designated operators and Customs, hosted by the UPU.
CDS.POST is an interoperable customs declaration system, which allows EDI CUSITM and CUSRSP messages to be exchanged between customs and designated operators so that customs formalities can be completed prior to the arrival of postal items (and ITMATT messages to be exchanged between postal operators).
Customs authorities have the option of using this system directly or interfacing it with their own system for risk assessment and payment of customs duties and taxes.
