The Consumer Protection Board is inspecting used and electric used-car dealers. Since 31 March 2026, used cars and used EVs must carry an 18-item Thai label (brand, model, year, mileage, accident and flood history, price, and more); EVs need 4 extra items. Every deposit or payment needs an immediate receipt, and contracts must be in Thai, in two identical copies. Buyers can cancel in 4 cases (price raised, late delivery, details or mileage not matching, transfer impossible), and refunds are due within 15 days. Penalties: up to 6 months jail or 100,000 baht for labelling breaches; up to 1 year or 200,000 baht for missing receipts or contracts. Check your labels, receipt book and contract template now.
