Thai EV makers exporting to Europe expect a QR-code "battery passport" to be mandatory from 2027, and an unnamed industry source says cars without it may not be sold there. Thailand has no confirmed domestic framework yet; ENTEC and the Office of Industrial Economics are studying one, with a proposal to the EV Board targeted for October 2026. For SMEs in EV parts and supply chains, the practical step is to ask your customers now what battery traceability data they will need from you.
