The document reports on ASEAN workshops held in March 2025 and January 2026 regarding vehicle type approval systems under the 1958 Agreement and UN Regulations. The Philippines raised concerns that not all UNR type approval certificates are available in the DETA database, with no prescribed timeline for uploading newly issued approvals or removing withdrawn certificates, and that access to DETA is limited to Contracting Parties to the 1958 Agreement. The Philippines proposes designating a national DETA focal point, securing official access for all regulatory authorities, requiring complete type approval certificate packages, and relaying concerns to WP.29/UN ECE Secretariat. Singapore and Thailand expressed interest in understanding DETA obligations and minimum commitments for Contracting Parties, and requested practical guidance on UN Regulations compliance.
