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 2020, AMS exchanged more than 800,000 of the ATIGA e-Form D through ASW. This helps traders to reduce paperwork and trade transaction costs, and subsequently expedite the cargo clearance.

AMS are now working on the expansion of the ASW for the electronic exchange of other trade-related documents, including:

  • ASEAN Customs Declaration Document (ACDD): the exchange of this document has started since December 2020 among Cambodia, Myanmar and Singapore, while remaining AMS will join the live operation by the end of 2021; and
  • Electronic Phytosanitary (e-Phyto) Certificate: AMS are working on aligning the data structure of electronic Phytosanitary (e-Phyto) Certificate with the International Plant Protection Convention (IPPC) e-Phyto Guideline before planning for the end-to-end test exchange among ready AMS by 2021.

To expand the scope of the ASW, the ASEAN Single Window Steering Committee (ASWSC) has developed the roadmap for the exchange of e-document with ASEAN Dialogue Partners (DPs) to identify the mandatory steps including a) feasibility study; b) legal framework establishment; and c) system implementation to enable the exchange of e-documents across the region. Currently, discussions are underway with Japan and the Republic of Korea on the possibility of exchanging the electronic Certificate of Origin, while other DPs express their interests to be engaged in the system integration.
