The ASEAN Single Window (ASW) is a regional initiative that connects and integrates National Single Window (NWS) of ASEAN Member States. The ASW's objective is to expedite cargo clearance and promote ASEAN economic integration by enabling the electronic exchange of border documents among ASEAN Member States.
Indonesia, Malaysia, Singapore, and Thailand are now using the ASW to exchange electronic certificates of origin. Once the Protocol for the Legal Framework to implement the ASEAN Single Window is fully ratified, the electronic certificates will be used for assigning preferential tariff rates under ATIGA and further expedite the customs clearance of goods between the participating ASEAN Member States in the ASW. Brunei and Vietnam are expected to join the ASW by mid-2017. Other ASEAN Member States are at the different stages of preparation and will join thereafter when they are ready.
ASEAN Member States are working to expand the ASW to support the exchange of export declaration information through the ASEAN Customs Declaration Document (ACDD) data to support Member States' Risk Management System and exchange of electronic Phyto-sanitary certificates. In the future, the ASW may also be used to exchange other documents such as cargo documentation, shipping manifests and other port or transport documents.
