Field Safety Corrective Actions and Recalls in Thailand

Field safety corrective actions, or FSCAs, are the recall-side counterpart of Thailand’s vigilance system, and their reporting windows are the shortest in the entire framework. This page explains what counts as an FSCA, when a report is triggered, what the initial and final reports must contain, how recalls are classified, and the independent enforcement powers held by the Secretary-General of the Thai FDA.

1. Key takeaways

An FSCA is an action taken in respect of a device already supplied, intended to reduce the risk of death or serious injury. It includes recalls, device modification, device replacement, device destruction, field safety notices, and updates and changes. A report is triggered when the product owner carries out any of these actions, whether in Thailand or abroad. The reporting rhythm is an initial report within 48 hours, followed by follow-up reports every 21 days until completion.

• Initial report. Due within 48 hours from the date the reporter becomes aware that the action will be implemented. The trigger point is awareness that the action will be carried out, not the date the action is actually completed, so the 48-hour clock starts at the moment the recall decision is made.
• Follow-up and final reports. Due every 21 days thereafter until the action is complete. The final report records the completion date, the effectiveness of the action and the disposal of affected stock.
• Initial report content. Minimum content includes a description of the device defect or adverse event, the locations where the FSCA is implemented, the affected persons where an adverse event is involved, and a health hazard assessment with related documents. Under HPVC guidance, the initial report uses form Ror Mor Por 3, attaching the action strategy, the health hazard assessment if completed, and the field safety notice.
• Recall classification. Three classes by potential health impact, with corresponding duties on recipients.
• Thai FDA powers. Section 55 paragraph 5 of the Medical Device Act gives the Secretary-General independent powers of seizure and mandatory recall.

2. Legal basis

The FSCA reporting obligations derive from the FSCA provisions of the MoPH Notification B.E. 2563 (2020), which set the 48-hour initial report and the 21-day follow-up cycle. The definition of an FSCA in that notification covers recall, device modification, device replacement, device destruction, field safety notice, and updates and changes. Procedural requirements for the initial report, including form Ror Mor Por 3 and the three-class recall classification, come from HPVC guidance. Enforcement powers rest on Section 55 paragraph 5 of the Medical Device Act B.E. 2551 (2008), replaced in the 2019 amendment, which empowers the Secretary-General to act independently.

Under Section 55 paragraph 5, for devices that do not conform to their authorisation or are unsafe, the Secretary-General may seize them from the manufacturer, importer, seller or holder, or order those parties to recall them from the market within a prescribed period, with the costs borne by those parties. Where the efficacy, quality or standards of a device do not match the registered dossier, or where the device is unsafe, the Secretary-General may execute a mandatory recall, publish the analysis results and contact the importer, manufacturer or distributor to implement it.

3. Expert insights

The single most consequential detail in the Thai FSCA regime is the starting point of the clock. The initial report is due within 48 hours from the date the reporter becomes aware that the action will be implemented, not from completion. This means the countdown begins at the moment the recall decision is made, which compresses the entire reporting preparation into a window shorter than two working days. Any capability that does not already exist at that moment, including translation capacity, hazard assessment templates and contact procedures, effectively cannot be built inside the window.

The second structural point is the dual-track nature of the regime. Companies run their own voluntary or company-initiated FSCAs under the notification and HPVC guidance, while the Secretary-General holds independent statutory powers to seize non-conforming or unsafe devices and order recalls at the obligation holders’ expense. A deficiency in the company-initiated track invites the statutory track, where the company loses control over timing, scope and messaging. Treating the 48-hour capability as a permanent readiness requirement, rather than an ad hoc response, is therefore not over-engineering but the minimum viable posture.

4. Practical recommendations

• Recognise that the 48-hour window is extremely short, which means reporting capability must exist before the first report ever arrives. Prepare three things in advance.
• First, a Thai-language template of the Ror Mor Por 3 form, so the primary submission can be completed in Thai without emergency translation.
• Second, a health hazard assessment template, so the assessment accompanying the initial report can be assembled quickly from existing risk management documentation.
• Third, a 24-hour contact mechanism with the licence holder, including holidays, so awareness transfers between parties without delay and the 48-hour clock can be managed from the moment the recall decision is made.
• Build the follow-up cadence into the same procedure, scheduling reports every 21 days until completion and planning the final report contents, covering the completion date, the effectiveness of the action and the disposal of affected stock, from the outset rather than reconstructing them at the end.
• Map the three recall classes onto internal triage criteria, including the immediate quarantine and acknowledgement duties for Class 1 and Class 2 recipients and the date-bound duty for Class 3, so downstream partners know their obligations before a notice is ever issued.

5. Verification checklist

• □ Confirm the FSCA provisions of the MoPH Notification B.E. 2563 (2020): 48-hour initial report and 21-day follow-up cycle.
• □ Confirm the FSCA definition: recall, device modification, device replacement, device destruction, field safety notice, and updates and changes.
• □ Confirm the starting point is the date of awareness that the action will be implemented.
• □ Confirm the minimum initial report content: description of the defect or adverse event, implementation locations, affected persons, and health hazard assessment.
• □ Confirm HPVC guidance on form Ror Mor Por 3 and the three-class recall classification.
• □ Confirm Section 55 paragraph 5 of the Medical Device Act B.E. 2551: the Secretary-General’s seizure and ordered recall powers, with costs borne by the obligation holders.
