Medical Device & IVD Regulations in Thailand

Thailand Medical Device Regulatory Framework

Medical device (non-IVD) regulations in Thailand are overseen by the Medical Device Control Division (MDCD) of the Thai Food and Drug Administration (Thai FDA), under the Ministry of Public Health. Any company that manufactures or imports medical devices for sale in Thailand must first obtain the appropriate license to produce or import their devices.

The current regulatory framework was established by the Medical Device Act B.E. 2551 (2008) and revised by the Medical Device Act (No. 2) B.E. 2562 (2019), which came into force in 2021.

Thai FDA medical device regulatory pathways

Thailand’s medical device classification system aligns with the ASEAN Medical Device Directive (AMDD). Medical devices and IVDs are classified into four categories of increasing risk: Class 1, Class 2, Class 3, and Class 4. The classification determines the regulatory pathway, documentation requirements, review timelines, and type of license issued. Licenses are valid for five years.

Types of Registration: Listing (Class 1) Low‑risk devices, such as bandages and basic instruments, follow the Listing Pathway. Documentation requirements include labeling, IFU, product specifications, device description, materials, Declaration of Conformity, and Letter of Authorization.

Devices on the Thai FDA “Positive List,” identified by GMDN codes, may qualify for automatic approval. In January 2025, Thai FDA implemented an auto-approval process for Class 1 professional-use only IVDs and non-IVDs under the positive list application.

Notification (Class 2 and Class 3) Moderate‑risk devices, including contact lenses and self‑testing IVDs, require a submission in the Common Submission Dossier Template (CSDT) format.

Licensing (Class 4) High‑risk devices and critical IVDs, such as those for HIV, HBV, or HCV, require a complete CSDT dossier and must undergo a full Thai FDA review.

Devices in Classes 2, 3, and 4 must provide a comprehensive technical file in the CSDT format, which includes risk analysis, validation and verification data, ISO 13485 quality certification, clinical or performance evidence, and letters of authorization. Abridged or reliance pathways may be used to reduce documentation requirements if the device meets Thai FDA eligibility criteria.

Pathways for medical device registration in Thailand

There are three pathways for Class 2, 3, and 4 medical devices and IVDs:

1. Full evaluation: This route is the standard registration process with the Thai FDA. It involves a detailed submission of technical documentation in CSDT format and a full review. Use the current Thai FDA checklist for the device and route. Administrative simplification does not remove the obligation to retain safety, performance and quality evidence or satisfy a product-specific request.

2. Abridged Evaluation Route: The Abridged Evaluation route is an option for devices approved by at least one recognized regulatory agency (US FDA, EU Notified Body, TGA, Japan MHLW, Health Canada, or WHO Prequalification) for a minimum of one year. Certain documents (Summary verification & validation, Risk analysis and waste disposal documentation) may be exempt for this route and avoid specialist review.

In-country representation requirements for medical devices in Thailand

Foreign manufacturers must appoint a local authorized representative or license holder who maintains a valid Establishment License, which is mandatory for manufacturing or importing medical devices in Thailand. Only Thai nationals or legal entities based in Thailand can apply for this license. Registrations are conducted under the name of the establishment license holder, who also holds the product license.

The license holder assumes full responsibility of your product registration, dossier submission, fee payments, renewals, and ongoing compliance obligations, including post-market vigilance and change notifications, and acts as the official liaison between the foreign manufacturer and the Thai FDA.

Medical device quality management system requirements in Thailand

Manufacturers of moderate‑ to high‑risk medical devices must comply with the updated Good Manufacturing Practice (GMP) requirements (Good Manufacturing Practice, B.E. 2566 (2023) and Good Importing and Sales Practice, B.E. 2566 (2023)). Compliance requires holding a GMP certificate, a Thai Conformity Assessment Standard (TCAS 13485) certificate, or an ISO 13485 certificate. Manufacturers of low‑risk devices are exempt from the certification requirement but must still upgrade their facilities and implement quality systems that meet the new GMP standards.

Compare routes before preparing the dossier

Begin with Thai classification, grouping and the licensed local importer's role. Compare standard evaluation with a qualifying reference-approval or reliance route using Thai FDA's current commercial import instructions. A foreign approval can reduce duplicate assessment only when its authority, device scope, evidence and authorization status meet the specified route conditions.

Create a gap table covering the proposed Thai intended use, configurations, CSDT sections, Essential Principles, testing, clinical/performance evidence, QMS and current labels/IFU. Identify documents that need legalization or translation rather than treating a shortened submission checklist as an exemption from underlying evidence.

Separate government review, applicant responses, local establishment licensing, import readiness and any testing into the launch plan. Plan fees using the current route and grouping scope. Before supply, assign postmarket reporting and change control, including the holder's access to distribution and complaint records.
