The Association of Southeast Asian Nations (ASEAN) has made strong strides in streamlining border procedures and embracing digital tools, yet progress remains uneven across Member States. Since 2022, ASEAN economies have reduced border complexities by an average of 6%, with notable gains in transparency, automation, and border agency co-operation. Regional initiatives such as the ASEAN Single Window, Tariff Finder, Customs Transit System, and new Authorised Economic Operator arrangements are helping to cut costs, strengthen resilience, and boost supply chain connectivity. Still, differences in the maturity and alignment of risk management systems, border agency co-operation mechanisms and interoperability frameworks continue to shape the pace of progress. By closing the gap between commitments and implementation, ASEAN can unlock deeper reductions in trade costs, enhance resilience against supply chain shocks, and reinforce its position as a dynamic hub of global trade integration. This report draws on the latest OECD Trade Facilitation Indicators (TFIs) to assess reform trends, highlight achievements, and identify remaining bottlenecks.
Facilitating Trade in the Association of Southeast Asian Nations
Abstract
Executive summary
ASEAN has made notable and accelerating progress in strengthening its trade facilitation environment over the past decade. Improvements have been driven by a combination of regional initiatives, domestic reforms, and the broader push to modernise border procedures in line with global standards. The OECD Trade Facilitation Indicators (TFIs) highlight that between 2022 and 2024, procedural and administrative hurdles at the border were reduced by an average of 6%, reflecting a strong commitment to enhancing efficiency, predictability, and transparency across ASEAN Member States (AMS).
Progress has been broad‑based, but not uniform. All AMS have improved their overall performance but starting points and reform trajectories differ significantly. Singapore, Malaysia, and Thailand consistently lead the region, setting high standards on automation, transparency, and border agency co‑operation. At the same time, Cambodia, Indonesia, Lao PDR, Myanmar, the Philippines, and Viet Nam have been emerging as dynamic reformers, recording some of the fastest improvements in the Asia‑Pacific region since 2022. These developments highlight both the collective momentum in the region and the remaining disparities that require continued attention.
A key factor behind ASEAN’s progress is the strength of its regional policy and regulatory frameworks. Over time, Member States have built an increasingly interconnected architecture that promotes harmonisation of border procedures, greater alignment of customs practices, and more consistent application of trade rules. Commitments undertaken through regional instruments have helped shape reforms related to advance rulings, pre‑arrival processing, transit facilitation, and the streamlining of trade documentation. Recent updates to regional frameworks reinforce ASEAN’s ambition to modernise, future‑proof its trade rules, and better support the evolving needs of businesses and supply chains.
These frameworks have been complemented by practical tools that gradually translate commitments into operational improvements. Digital platforms such as the ASEAN Single Window (ASW) have significantly expanded the electronic exchange of trade documents, reducing delays and paperwork. The ASEAN Customs Transit System (ACTS) has improved the predictability of goods movement across borders, particularly for transit traffic. The ASEAN Tariff Finder has enhanced access to comprehensive and up‑to‑date trade information, increasingly helping traders navigate tariff schedules, rules of origin, and non‑tariff measures. Each of these instruments has contributed to greater transparency, lower compliance costs, and improved regulatory certainty for the private sector.
Despite strong progress, implementation challenges remain. While most AMS publish trade regulations, tariff schedules, and procedural guidelines online, the completeness, clarity, and frequency of updates vary. Some AMS still lack comprehensive and centralised publication of fees and charges, judicial decisions, or detailed penalty provisions, making it harder for businesses to anticipate costs and obligations. Public consultation practices also differ widely, limiting opportunities for traders – especially SMEs – to provide timely input on proposed regulatory changes.
Automation has been one of the most dynamic areas of reform, but the benefits are unevenly distributed. Many AMS have made strides in digitising customs declarations, expanding electronic submission of documents, and adopting automated risk management systems. Yet gaps remain in interoperability between border agencies, the continued reliance on paper documents in certain situations, and the limited integration of some agencies into national Single Window platforms. These inconsistencies reduce the full potential of digitalisation, especially for businesses operating across multiple borders.
Border agency co‑operation stands out as an area of particularly rapid progress, both domestically and across borders. Many AMS have strengthened co‑ordination between customs and other regulatory bodies, introduced joint inspection mechanisms, and improved information sharing. Cross‑border co‑operation has also advanced, supported by regional initiatives and shared digital systems. Still, differences in working hours, inspection practices, ICT capacity, and legal frameworks continue to slow seamless goods movement and prevent more widespread adoption of joint border procedures.
The economic impacts of trade facilitation reforms in ASEAN are significant. Streamlined procedures and greater use of automation reduce time and costs for traders, supporting greater competitiveness and integration into global supply chains. This report highlights that improvements in trade facilitation have been helping the Asia-Pacific region expand into new export markets, increase traded volumes with existing partners, and strengthen resilience during supply chain disruptions. Importantly, enhancements in practical implementation, such as through wider use of pre‑arrival processing, post‑clearance audits, or risk‑based controls, tend to generate stronger trade benefits than regulatory reforms alone. This underscores the importance of ensuring that commitments translate into everyday practice for traders.
Looking ahead, ASEAN faces both opportunities and challenges. Deepening regional integration and the transition towards a more digital and interconnected trade ecosystem mean that trade facilitation will remain central to competitiveness and supply chain resilience. Ensuring that all AMS fully benefit from the region’s tools and frameworks will require sustained political commitment, targeted capacity building, and continued co‑ordination at both domestic and regional levels. Strengthening interoperability, expanding automation, improving transparency, and aligning trade facilitation with the region’s growing digital trade agenda will be essential. By consolidating progress and bridging existing implementation gaps, ASEAN can further reduce trade costs, foster more predictable and efficient cross‑border trade, and enhance its position as a dynamic hub for regional and global supply chains.
The OECD Trade Facilitation Indicators (TFIs) show that ASEAN Member States (AMS) have undertaken substantial reforms to streamline border procedures since 2022, although progress remains uneven. Regional frameworks and initiatives advanced over the recent years – such as the ASEAN Trade in Goods Agreement (ATIGA), the ASEAN Customs Transit System (ACTS), and the ASEAN Single Window – have helped reduce procedural complexities and administrative hurdles at the border by 6% on average. However, ASEAN’s trade facilitation landscape remains heterogeneous, with progress varying considerably by policy area and Member State.
Within the region, Singapore, Thailand, and Malaysia continue to set the benchmark – ranking not only as ASEAN’s top performers but also among the strongest performers across the wider Asia-Pacific region. Lao PDR, Cambodia, the Philippines, Thailand, Indonesia, Myanmar, and Viet Nam stand out among the top ten reformers in the Asia-Pacific region between 2022 and 2024, underscoring ASEAN’s collective reform dynamism.
Consistent with global trends, domestic and cross-border agency co-operation are the top areas of progress, yet from a low base and with the greatest scope for further improvement. Domestic border agency co-operation, shaped by a combination of institutional and regulatory reforms, not only enhanced efficiency within national borders but also served as a catalyst for stronger cross-border agency co-operation. However, in line with global trends, border agency co-operation in ASEAN began from a relatively limited baseline and holds the largest potential for further improvement.
In ASEAN, comprehensive and accessible trade-related information is increasingly available online through customs portals, national trade repositories, and enquiry points, as well as regional tools such as the ASEAN Trade Repository and the ASEAN Tariff Finder. Many AMS now publish trade-related regulations, tariff schedules, advance ruling procedures, and documentary requirements, with most also offering bilingual access and user manuals for new digital systems. Nevertheless, keeping this information up to date and expanding coverage remains essential to reduce administrative burdens and help businesses, including SMEs, anticipate and adapt to new policies.
Further efforts are needed in ASEAN to close the gaps between establishing regulatory frameworks for trade facilitation and their full implementation in practice. Certified trader programmes, post-clearance audits, and expedited treatment for perishable goods exist in most AMS, but their application remains uneven. Certified trader schemes are not yet region-wide, post-clearance audits are inconsistently applied, and priority treatment for perishables often faces delays where risk management is fragmented across agencies. Beyond strengthening operational practices, ASEAN should also strengthen the policy environment for going paperless. This means building on electronic transaction frameworks to ensure that trade facilitation reforms are fully digital, interoperable, and future-oriented.
