  • Batch or serial number (if applicable).
  • Manufacturing and expiration dates (if applicable).
• Language: All labels must be in Portuguese and should include symbols or graphics, if relevant, for clarity.

4. Quality Management System (QMS) Evidence

• ISO 13485 Certification (or equivalent): Proof of the manufacturer’s compliance with an appropriate QMS, typically ISO 13485, is recommended for Class I devices.
• Manufacturing and Quality Control Procedures: Documentation on the manufacturing processes and quality control measures implemented to ensure consistent device quality.

5. Risk Management File

• Risk Analysis: Comprehensive risk analysis identifying potential risks associated with the device, as per ISO 14971 or equivalent standards.
• Mitigation Strategies: Steps taken to reduce or control identified risks, including any design or labeling modifications.
• Risk-Benefit Assessment: Evaluation showing that the device’s benefits outweigh its potential risks.

6. Declaration of Conformity

• Compliance Statement: Declaration that the device complies with all applicable Brazilian regulations, as well as relevant international standards.
• Signed by Manufacturer: Must be signed by an authorized person from the manufacturer, affirming that the device conforms to required standards.

7. Biocompatibility and Safety Testing (if applicable)

• Biocompatibility Reports: For devices in contact with the human body, biocompatibility test reports demonstrating that the materials are safe.
• Electrical and Mechanical Safety Testing: If the device is electrical or mechanical, reports demonstrating compliance with safety standards (e.g., IEC 60601-1 for electrical devices).
• Sterility Assurance Documentation (if applicable): If the device is marketed as sterile, provide sterilization validation results, sterility assurance documentation, and packaging integrity test results.

8. Clinical Data (if applicable)

• Clinical Performance Evidence: For certain Class I devices, basic clinical performance data may be required to support the device’s safety and efficacy.
• Literature Review or Study Summaries: If clinical data is required, summaries of studies or literature reviews that support the device’s safety and intended use.

9. Authorization Letter for Brazilian Registration Holder (BRH)

• BRH Appointment Letter: Authorization letter from the foreign manufacturer appointing the Brazilian Registration Holder (BRH) as the official representative in Brazil.
• Signature and Contact Information: Should include contact information for both the manufacturer and BRH.

10. Other Supporting Documentation (if applicable)

• Product Test Reports: Any additional testing reports demonstrating that the device meets relevant safety or performance standards.
• Material Safety Data Sheet (MSDS): If the device contains any hazardous materials, include an MSDS for safety information.
• Post-Market Surveillance Procedures: Summary of the plan for monitoring the device’s performance and safety once it’s on the market, in compliance with Brazil's vigilance requirements.

Preparation Tips for Application Documents

• Ensure Accurate Translations: All documents, including IFUs and labels, must be in Portuguese. Translations must be accurate and professionally done.
• Organize in ANVISA’s Format: Structure the documentation according to ANVISA’s guidelines for easy review and faster processing.
• Verify Completeness: Double-check each document for completeness and ensure it aligns with the device’s classification and intended use.

By following these documentation requirements and guidelines, you can improve the chances of a smooth and successful Class I medical device registration process with ANVISA.
