Thailand’s updated medical device labelling rules are in force

Home-use and professional devices follow different language rules

A device intended for ordinary home users must have clearly readable Thai labelling and accompanying information. Professional-use medical devices may use either Thai or English, provided the information is clear; other languages can be added as long as they do not conflict with the required text.

The rules require core identifying and safety information to be presented clearly. Depending on the product, that includes the device name and intended purpose, manufacturer or importer information, regulatory identifiers, lot, model or serial details, and relevant manufacturing, expiry or service-life information.

Instructions can contain the practical detail that will not fit on the label itself, including how the device is used and stored, as well as warnings, contraindications and precautions where relevant. The revised framework also permits electronic presentation in specified cases, including digital channels used for software-based medical devices and certain instructions.

For practical context, see Thailand economy and finance. This development also connects with Thailand SEC updates disclosure rules for private funds.

The transition is gradual rather than an overnight relabelling

Products do not all have to show the new-format materials immediately. The transition clause allows labels and instructions prepared under the 2020 notification and already in existence before the new rules took effect to remain usable for no more than two years from 20 June 2026.

That matters for both consumers and businesses. Different packaging formats may legitimately coexist during the transition, so an older-looking label is not by itself evidence that a product is non-compliant. Importers and sellers still need to determine whether a particular product falls within the transitional provision and whether a more specific medical-device rule overrides the general notification.

For regulated operators, the change is therefore more than a packaging redesign. It affects the content and language of labels, instructions and, where permitted, electronic information supplied with a device.

Clearer information does not guarantee clinical suitability

For a person buying a device for home use, the most visible change is the expectation of clearer Thai-language information about what the product is for and how it should be used safely. This can make it easier to distinguish a device’s intended use from marketing claims and to spot warnings before use.

The notification also bars false, exaggerated or materially misleading claims in required labelling and documentation. That improves transparency, but it does not establish that a device will work for every user or that it is appropriate for a particular diagnosis. Questions about treatment or diagnosis still depend on the individual medical situation, not on the format of the label.
