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are available in the DETA database, with no prescribed timeline for uploading newly issued approvals or removing withdrawn certificates, and that access to DETA is limited to Contracting Parties to the 1958 Agreement.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

IWVTA is an internationally recognised whole vehicle type approval scheme within the revised 1958 Agreement framework. It establishes mutual recognition of vehicle type approvals at the whole vehicle level across Contracting Parties, eliminating requirements for further testing, documentation, or certification for safety, environment, energy, and anti-theft. IWVTA comprises two approaches: U-IWVTA applies the highest stringency of latest UN Regulations, while L-IWVTA permits omissions or lower stringency versions. The scope is limited to passenger cars. Merits include simplified type approval systems, reduced testing and administrative costs, and shortened processing times.

The 1st DETA/IWVTA Joint Workshop is scheduled for June 17, 2026, 9:30–12:30 (CEST) as a hybrid meeting in Flensburg. The provisional agenda includes opening remarks from the DETA Chair, IWVTA Chair, and President of KBA. Part 1 covers DETA topics: what DETA is, a demonstration, ASEAN countries’ expectations, and ways to make DETA more attractive. Part 2 covers IWVTA topics: what IWVTA is, industry’s expectations, issuance and acceptance of IWVTA certificates in the EU, and ways to make IWVTA more attractive. The workshop concludes with any other business.

A Universal International Whole Vehicle Type Approval issued for vehicles of category M₁ under UN R0 that includes type-approval under the UN Regulations concerned shall be considered equivalent to an EU type-approval granted under Framework Regulation (EU) 2018/858. The approval authority granting EU-WVTA must confirm for all variants and versions within the EU-WVTA vehicle type the equivalence of the Part III list and that the EU-WVTA type is covered by the IWVTA class and IWVTA type.
