The IWG on SCUNV held its twentieth meeting on 5 March 2026 with participants from eleven countries and multiple organizations. The group focused on Draft Resolution SCUNV-20-02, specifically Chapter 9 on used vehicle emissions standards. The group confirmed Euro 4 as the minimum emissions requirement and agreed that both OBD and tailpipe testing are acceptable verification methods. Optional guidance for Euro 5/6 vehicles will be included without changing the minimum requirement. References to pre-1980 vehicles will be removed. CITA will submit revised Chapter 9 wording by 9 March 2026 for WP.29 presentation on 11 March 2026. The document submission deadline for the June 2026 WP.29 session is 31 March 2026.

The Draft Resolution on Used Vehicles was discussed; Chapter 9 on Environment was updated to remove references to Euro levels and replace them with standard text linked to model year. Footnote 2 required clarification regarding regional requirements. Editorial proposals were reviewed and agreed. The Secretary would compare Chapter 9 with previous proposals, with comments requested by 8 April. Agreement was reached on text for the June WP29 meeting, with formal review at June meeting and adoption at November WP29 session. Editorial comments on transfer of information related to vehicles in transfer to low- and middle-income countries were reviewed and agreed.

The draft resolution establishes minimum inspection criteria for used vehicles to ensure they meet safety and environmental standards before importation. The document provides performance-based, technology-neutral requirements applicable under UN vehicle agreements. Inspection covers vehicle identification, braking systems, steering, visibility, lighting, axles, suspension, chassis, safety equipment, environmental emissions, and additional tests for passenger vehicles and electric/hybrid vehicles. Annex 1 specifies inspection methods and rejection criteria; Annex 2 provides a certificate template for communicating inspection results to importers.
