    TL;DR

    Medical devices in Thailand are regulated under the Medical Device Act B.E. 2551 (2008), substantially amended in 2019 to align with the ASEAN Medical Device Directive (AMDD). The FDA-Thai Medical Device Control Division administers. Devices are classified into four risk classes (1, 2, 3, 4). Pre-market obligations include notification (Class 1) or registration (Classes 2-4); post-market includes adverse-event reporting.

    Risk Classes

    ClassRiskPre-market
    1Low (bandages, manual surgical)Notification
    2Low-medium (IVD, syringes)Registration
    3Medium-high (orthopaedic, electromedical)Registration + QMS evidence
    4High (implants, life-supporting)Registration + clinical data

    Registration Path

    1. Classify device per AMDD rules.
    2. Compile Common Submission Dossier Template (CSDT).
    3. QMS evidence (ISO 13485 commonly accepted).
    4. Clinical evaluation report.
    5. FDA-Thai review (timeline by class).
    6. Licence issued; renewable per term.

    Post-Market Obligations

    • Adverse-event reporting (15 / 30 / 90 day windows by severity).
    • Field-safety corrective actions.
    • Re-registration on major change.
    • Annual reports for Class 3 / 4.

    Common Mistakes

    • Misclassifying borderline products (e.g., wellness apps that meet medical-device definition).
    • Using foreign clinical data without bridging study.
    • Skipping QMS evidence.

    FAQs

    1. Software-as-a-medical-device (SaMD)?
