About ASEAN Single Window


The ASEAN Single Window (ASW) connects and integrates the National Single Windows (NSW) of ASEAN Member States (AMS) to exchange electronic trade-related documents. The system enables a single submission of data, a single synchronous processing of information and a single decision-making for Customs release and clearance among AMS and participating countries.

ASW is the environment that provides the secure information technology (IT) architecture and legal framework that will allow trade, transport, and commercial data to be exchanged electronically among government agencies and private sectors. ASW aims to expedite the cargo clearance process, reduce cost and time of doing business, and enhance trade efficiency and competitiveness.

Scope and status of the ASW

The ratification of the Protocol on the Legal Framework to Implement the ASW (PLF) has enabled the live operation of the ASW among ASEAN Member States. In 2021, AMS have exchanged more than 900,000 of the ATIGA e-Form D through ASW. This helps traders to reduce paperwork and trade transaction costs, and subsequently expedite the cargo clearance.

ASEAN is now working on the exchange of other trade-related documents among AMS, including:

  • ASEAN Customs Declaration Document (ACDD): the exchange of this document has started since December 2020 among Cambodia, Myanmar, and Singapore. Malaysia and Thailand joined in 2021 while the Philippines joined in January 2022. The remaining AMSs are expected to join the live operation within 2022;
  • Electronic Phytosanitary (e-Phyto) Certificate: the exchange of this document is targeted in Q3 2022 by Indonesia, Malaysia, and Thailand; and
  • Electronic Animal Health (e-AH) and Electronic Food Safety (e-FS) certificates are under the discussion.

To expand the scope of the ASW, AMSs are discussing with China, Japan, the Republic of Korea, and the United States focusing on the exchange of electronic Certificate of Origin (e-CO), electronic Phytosanitary (e-Phyto) certificate, and Customs Declaration Information.
