RELATED INSIGHTS

On August 5, 2026, the Consumer Case Division of Thailand’s Civil Court rendered a judgment in a case involving a beauty clinic that advertised acne scar treatments using claims that the clinic was operated by a specialist physician and that the treatment, allegedly involving stem cell technology, could permanently remove acne scars. The plaintiff brought a claim against both the physician-owner and the clinic company, alleging that the advertisements were false and induced her to purchase the treatment. The court found that the clinic was liable for the false representations and that the physician-owner, as both the authorized director of the company and the medical practitioner who provided treatment, was jointly responsible. Although the plaintiff could not fully prove all damages claimed, the court awarded compensation of THB 20,000, together with interest. While the judgment arose from a consumer protection dispute, it serves as a valuable reminder that medical facility advertisements in Thailand are regulated and may expose clinics and healthcare providers not only to regulatory enforcement but also to civil liability from patients who rely on misleading promotional claims. Regulatory Framework Governing Medical Facility Advertisements Medical facility advertising in Thailand is governed by the Medical Facility Act B.E. 2541 (1998), as amended by the Medical Facility Act (No. 4) B.E. 2559 (2016). The principal secondary legislation is the Department of Health Service Support (DoHSS) Notification Re: Rules, Procedures, Conditions, and Fees for an Advertisement or Publication Concerning a Medical Facility, which came into force on November 25, 2019. Under this notification, “advertising” includes any act, by any means, that causes members of the public to see, hear, or otherwise become aware of a message, sound, or image for the commercial benefit of a medical facility. This broad definition covers not only traditional media but also clinic websites, social

On June 30, 2026, Indonesia’s National Agency of Drug and Food Control (BPOM) issued BPOM Regulation No. 11 of 2026 on Food Packaging, which expands the list of approved food-contact substances and recognizes a broader range of permissible functions for those substances. The new regulation, which revokes BPOM Regulation No. 20 of 2019, reflects developments in packaging technology and materials science. Although the new regulation provides more advantages to business actors by adding more food contact substances to the approved list for use in food packaging, there are more stringent rules and restrictions for testing. One of the most significant changes is a comprehensive migration-testing framework that sets out requirements for packaging materials, testing conditions, food simulants, and specific migration limits. Overall and Specific Migration Under BPOM Regulation No. 20 of 2019, migration requirements were primarily set out within the lists of approved food-contact substances and packaging materials. BPOM Regulation No. 11 of 2026 instead expressly requires packaging materials that come into direct contact with food to meet both overall and specific migration limits. These are defined as follows: Overall migration: The total quantity of all substances that migrate from the packaging, regardless of whether the substances are hazardous or nonhazardous to health. Specific migration: The quantity of a particular identified substance known to be hazardous to health that migrates from the packaging. Stricter Limits on Heavy Metals The overall migration limit for plastic packaging remains unchanged under both regulations at 60 mg/kg or 10 mg/dm². However, the new regulation introduces significant changes to the regulation of heavy metals. Under the 2019 regulation, four heavy metals—lead, cadmium, chromium VI, and mercury—were subject to a single combined limit of 1 mg/kg. The 2026 regulation, however, requires each heavy metal to meet its own individual specific migration limit, adds arsenic as

Blind boxes and collectibles have become increasingly popular, driven by the excitement of not knowing which character or design will be revealed until the package is opened. While most visible in the art toy market, the same concept is also used in the food industry. Confectionery, snacks, and other food products are sometimes sold with toys, character figures, cards, or other collectibles. A package might, for example, contain one of ten possible characters, with consumers knowing that an item is included but not which one they will receive. Some collections may also feature rare or “secret” items. For food businesses, however, adding a randomized toy or collectible involves more than a marketing decision. The food, the nonfood item, and the randomized mechanism may each raise different regulatory considerations in Thailand. Thai FDA Requirements for Nonfood Objects Packaged with Food The main food regulatory consideration is Ministry of Public Health Notification No. 310 B.E. 2551 (2008), which regulates food packaged together with things or objects that are not food. Under Notification No. 310, certain nonfood objects may be packaged together with food where they fall within specified exceptions, including objects that serve the following purposes: Maintaining the quality or standard of the food, such as a desiccant or oxygen absorber; Serving as a seasoning or as part of food preparation, such as chili powder sachets or seasoning sachets contained in instant noodle packages; or Functioning as an eating or food-preparation utensil, such as a spoon or fork included with instant noodles. Other nonfood objects that do not fall within these categories generally should not be placed inside the food container together with the food. Where a toy, collectible, or other nonfood object is intended to be sold together with a food product, businesses should therefore carefully consider the nature of
