Thailand Strengthens Consumer Rights with New Product Defect Law
The Thai Parliament has overwhelmingly approved a significant overhaul of consumer protection laws, enacting a measure often referred to as the ‘Lemon Law.’ This legislation is poised to shift the burden of proof for product defects from consumers to sellers, substantially enhancing consumer rights.
Key Provisions of the New Legislation
The proposed ‘Product Defect Liability Act’ passed the House of Representatives with a unanimous vote of 420 in favor, and no votes against or abstentions. At its core, the law prioritizes seller accountability for product defects that emerge within a specified period.
Under the new regulations, sellers will be responsible for defects in general products, electrical appliances, and motorcycles that manifest within six months of delivery. For automobiles, this period is extended to one year.
Consumers will have the right to demand repairs, replacements, price reductions, or full refunds for confirmed product defects. Notably, for significant issues, consumers can request immediate replacement of general products within seven days of purchase, and for electronic and electrical goods, within 14 days.
Repair and Replacement Timelines
Repair timelines are also being standardized. General products must be repaired within a maximum of 60 days, while vehicles require repairs to be completed within 90 days. For automobiles and motorcycles, if a defect is confirmed within the stipulated usage period and mileage, sellers will be liable regardless of whether the issue is considered a manufacturing defect or not.
Government Expectations and Market Impact
Government officials anticipate that this new law will reduce disputes and the financial burden of litigation between consumers and sellers. Furthermore, it is expected to encourage businesses to prioritize product quality, thereby fostering greater trust in the overall market.
Comparison with South Korea’s Consumer Law
South Korea already has a version of the ‘Lemon Law’ in effect, though its application is currently limited to automobiles. This contrasts with Thailand and the United States, where similar laws often apply to a wider range of consumer goods.
Even South Korea’s existing automotive ‘Lemon Law,’ implemented in 2019, faces limitations. Consumers bear the initial burden of proving a defect, and the process for replacement or refunds can be lengthy and complex. Information asymmetry between manufacturers and consumers also remains a challenge.
As of 2026 estimates, South Korea ranks around 15th globally in terms of Gross Domestic Product (GDP), while Thailand is positioned in the 30s. This economic disparity may influence the implementation and impact of such consumer protection measures.
