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 between Indonesia, Malaysia, Singapore, Thailand, and Vietnam since 1 January 2018, which was followed by Brunei Darussalam, Cambodia, Lao PDR, Myanmar and the Philippines in 2019. Under the live operation of the ASW, granting of preferential tariff treatment would be based on the Certificate of Origin (CO) Form D under the ASEAN Trade in Goods Agreement (ATIGA) that is electronically transmitted via the ASW (ATIGA e-Form D).

Based on the Regional Services (RS) Portal, the ASW exchanged more than 500,000 of the ATIGA e-Form D in 2019, expediting cargo clearance and reducing paperwork for traders.

With the successful on-boarding of all AMS for the live operation of the ASW, AMS are now working on expansion of the ASW for the electronic exchange of other trade-related documents such as:

  • The exchange of ASEAN Customs Declaration Document (ACDD) are currently being tested among ready AMS and expected for the Live Operation within 2020; and
  • AMS are currently preparing their national system and regulations to allow the exchange of electronic Phytosanitary (e-Phyto) Certificate, electronic Animal Health (e-AH) Certificate and electronic Food Safety (e-FS) Certificate through the ASW.
