The time cycle for Class C medical device registration with Singapore's Health Sciences Authority (HSA) typically takes around 3 to 6 months. However, the exact duration can vary based on several factors, such as:

Factors Affecting the Time Cycle:

1. Completeness and Accuracy of the Submission:

   • If the application is complete and all required documents are submitted correctly, the review process is likely to be faster.
   • Incomplete or incorrect submissions may cause delays, as the HSA will need additional information or clarification.

2. Complexity of the Device:

   • Devices with higher complexity or new technologies may require more time for review, especially if additional safety, performance, or clinical data needs to be assessed.

3. Clinical Data Evaluation:

   • If the device requires clinical data (e.g., clinical trials, clinical evaluation reports), the review process may take longer due to the additional evaluation of this data.

4. Inspection or Audit Requirements:

   • In some cases, HSA may require an inspection of the manufacturing facility or a review of the manufacturer’s quality management system. This can add time to the approval process.

5. Post-Market Surveillance Requirements:

   • If there are extensive post-market surveillance plans or if the device has a higher risk profile, additional documentation may be requested, extending the review period.

Typical Timeline:

• Initial Submission and Review: The initial review of the application typically takes 3 to 6 months.
• Additional Information Requests: If HSA requires more information or clarification, this may extend the timeline, as the applicant needs time to gather and submit the requested details.
• Approval: Once HSA is satisfied with the documentation and data provided, the device is registered, and the registration certificate is issued.

Key Milestones in the Registration Process:

1. Application Submission: After logging into the HSA Medical Device Registration (MDR) portal and submitting the necessary documentation.
2. Application Review: HSA evaluates the device, including clinical data, risk management, and compliance with relevant standards.
3. Decision or Additional Information: HSA may request additional information or provide a decision on approval. If additional information is needed, the applicant must respond promptly.
4. Approval and Registration: Once the review is completed successfully, HSA will approve the device, and the registration certificate will be issued.

Note on Variability:

• Device-Specific Factors: Devices that are already well-documented, have prior approvals in other regions (e.g., FDA or CE marking), or are lower risk may move through the process more quickly than novel or high-risk devices.
• Workload of HSA: The processing time may also be affected by the current workload of HSA, so it’s a good idea to check for any potential backlogs or delays before submission.
