Thailand’s new labeling requirements for medical devices, which include for the first time a unique device identification (UDI) requirement for software as a medical device (SaMD), take effect on June 20, 2026. The Notification of the Ministry of Public Health regarding Criteria, Methods, and Conditions on Labeling and Instructions for Use for Medical Devices 2025, which replaces a similar notification from 2020, was published in the Government Gazette on December 22, 2025.
To ensure clarity, modernity, and patient safety, the regulation requires domestic manufacturers and importers to provide labels and instructions for use (IFU) that are clearly legible, complete, and free of false or misleading claims. It also permits IFU to be provided in electronic format, such as via QR codes, websites, or other digital channels—directly relevant to SaMD, where physical labels are impractical and electronic presentation is the natural medium.
The notification distinguishes two categories for labeling language. Home-use medical devices (for lay users outside healthcare facilities) must have labels and IFU in Thai. Professional-use medical devices may display labels and documentation in either Thai or English. This distinction is significant for SaMD developers: software intended for clinical professionals may use English-language interfaces and IFU, while consumer-facing health applications must provide Thai-language content.
Labeling and UDI Requirements
Labels and IFU must include, at a minimum:
Product name and intended purpose
Quantity or volume
Name and address of domestic manufacturer or importer
Thai FDA approval number
Lot, version, or serial number
Manufacturing date and expiry date
For SaMD, the version number requirement is particularly relevant. The regulation also mandates display of a UDI code for SaMD in risk category 2 (moderate-risk), category 3 (moderate- to high-risk), and category 4 (high-risk), according to Thailand’s medical device risk classification system (which complies with the ASEAN Medical Device Directive and the EU Medical Device Regulation). UDI details must be displayed as part of
