Trade officials from several Asia-Pacific economies met in Kuala Lumpur to discuss customs clearance and logistics bottlenecks.
Singapore representatives highlighted digital documentation pilots that have reduced port processing times for selected goods.
A joint statement noted progress on harmonised standards but stopped short of announcing binding commitments.
Delegates discussed mutual recognition of inspection certificates for agricultural products and electronics, areas where divergent paperwork has historically delayed cross-border shipments. Small exporters said even modest alignment could reduce costs for firms without dedicated customs teams.
Singapore's delegation highlighted pilot programmes linking port authorities through shared digital platforms, allowing selected shipments to clear customs with fewer manual checks. Similar trials are being explored at secondary ports in neighbouring economies.
Officials agreed to reconvene in November to review implementation timelines, though observers cautioned that domestic regulatory approvals in each country may extend the path to full harmonisation.
