E-Commerce Consumer Rights in Thailand 2026

The Legal Framework

Thai e-commerce consumer protection is governed by: (1) Consumer Protection Act B.E. 2522 (1979) (general consumer rights), (2) Direct Sales and Direct Marketing Act B.E. 2545 (2002) (covers online purchases — the key law), (3) Electronic Transactions Act B.E. 2544 (2001), and (4) PDPA (data protection).

Your Right to Return (7-Day Cooling Off)

Under the Direct Sales and Direct Marketing Act, consumers have the right to cancel an online purchase within 7 days of receiving the goods — no reason required. The seller must refund the full amount within 15 days of receiving the returned goods. This applies to purchases from Thai-registered sellers. Exceptions: perishable goods, customized products, digital downloads once accessed, underwear/swimwear.

Refund Obligations

Sellers must provide refunds for: defective goods (within warranty period or 2 years if no warranty stated), goods not matching description, non-delivery. Refunds must be in the original payment method. "Store credit only" policies that deny cash refunds for defective goods are illegal.

False Advertising

The Consumer Protection Act prohibits advertisements that are false, exaggerated, or misleading. Penalties: up to 6 months imprisonment and THB 50,000 fine for the advertiser. The OCPB can order corrective advertising and compensation. This covers social media ads, influencer endorsements, and marketplace listings.

Filing a Consumer Complaint

OCPB (Office of the Consumer Protection Board): File online at ocpb.go.th or in person. Free. Process: investigation (30-60 days) → mediation → enforcement order. Small Claims Court: For claims under THB 300,000. Filing fee THB 200. No lawyer required. Decision within 1-2 months. Consumer Case Division: For larger claims. The court can award punitive damages up to 2x actual damages.

Platform Liability

Lazada, Shopee, and other platforms are responsible for ensuring sellers comply with consumer protection laws. If a seller disappears, the platform must assist with refunds through its buyer protection program. For cross-border purchases (AliExpress, Taobao), Thai consumer law may not apply — use the platform's own dispute resolution.

Practical Tips

Always screenshot product listings before ordering. Keep all receipts and correspondence. Pay through the platform (not direct bank transfer) for buyer protection. For expensive items, check seller ratings and reviews carefully.
