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are available in the DETA database, with no prescribed timeline for uploading newly issued approvals or removing withdrawn certificates, and that access to DETA is limited to Contracting Parties to the 1958 Agreement.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.

DETA is the secure internet database for exchanging type approval documentation between Contracting Parties of the 1958 Agreement, as required by Revision 3 of that Agreement. Currently hosted by Germany, DETA stores approval notices, extensions, refusals, withdrawals, and related documents including test reports and communications. Access is limited to registered users: Contracting Parties nominate a single DETA Focal Point to manage accounts; manufacturers and technical services request access via their approval authority. As of the workshop date, 41 Contracting Parties had notified their Focal Point, approximately 132,000 approvals were uploaded by 23 Type Approval Authorities, and approximately 7,735 manufacturers were registered.

Questionnaire on DETA/IWVTA Workshop.

Part 2: IWVTA session asks about level of understanding of IWVTA session as high, moderate, or low; items needing more explanation; and for Authorities, how Regulation No. 0 could be improved to make IWVTA acceptable for use as part of vehicle type-approval process. The future workshop section asks about expectations for next workshop and suggestions on contents, timing, and length.
