Thailand: FDA Outlines the Differences Between the “Document Addition System” and “Renewal System” in SkyNet

On July 18, 2025, the Thai Food and Drug Administration (FDA) issued a press release clarifying the differences between the Document Addition System (Upgrade to Full CSDT) and the Renewal System within SkyNet, the regulatory platform for medical device registrations. This clarification is critical for stakeholders managing existing licenses or notification certificates.

To view the official announcement (in Thai), refer to: [กองควบคุมเครื่องมือแพทย์ | Thai FDA Official Website].

Purpose of the Two Systems

The Thai FDA highlighted the distinct purposes of the two systems:

  • Document Addition System (Upgrade to Full CSDT)
    • Designed for operators who previously registered their products with partial document exemptions (Partial 1, Partial 2, or Abridged).
    • Allows voluntary upgrading of registrations to the Full Common Submission Dossier Template (CSDT) format.
    • Does not extend the current registration validity.
  • Renewal System
    • Allows renewal of registrations that are nearing expiration.
    • Extends registration validity for an additional five years.
    • Applicable to all registration types (Partial, Abridged, or Full CSDT).

Document Addition System (Upgrade to Full CSDT)

What is it?
A voluntary channel for operators with partially exempted documentation to upgrade to Full CSDT.

Why upgrade?

  • To demonstrate compliance with full technical documentation.
  • To meet certain client or partner requirements.
  • To become eligible for the Thai Innovation List (for domestic manufacturers).

Key Points:

  • Not a renewal — does not extend validity.
  • No fees required.
  • Voluntary — operators may choose whether to upgrade.

Renewal System

What is it?
A process to extend the validity of medical device registrations for an additional five years.

When to apply?

  • Within 90 days before expiration.
  • Example: If a registration expires on December 31, 2025, renewal applications can start from October 1, 2025.

Key Points:

  • Mandatory for all registrations (Partial, Abridged, or Full CSDT).
  • No Full CSDT upgrade required before renewal.

Summary

  • To upgrade documentation to Full CSDT → Use the Document Addition System.
  • To extend validity of an expiring registration → Use the Renewal System.

Implications to Clients

Stakeholders should carefully determine which system applies to their situation:

  • Use the Document Addition System if you wish to upgrade exempted registrations to Full CSDT.
  • Use the Renewal System if your license or notification certificate is close to expiration.

This ensures compliance and uninterrupted product distribution in Thailand.
