Comprehensive Guide to Raw Material Inspection and Approval in Medical Device Manufacturing

1) Purpose

This SOP defines the process for inspecting and approving raw materials used in the manufacturing of medical devices. The objective is to ensure that all materials meet predefined quality and compliance standards, minimizing risks to product safety, efficacy, and regulatory compliance.

2) Scope

This SOP applies to all raw materials procured for medical device manufacturing. It includes materials such as polymers, metals, electronic components, and consumables. The process covers initial material receipt, inspection, testing, and final approval or rejection.

3) Responsibilities

– Procurement Team: Ensures materials are procured from approved suppliers and verifies accompanying documentation.
– Quality Control (QC): Conducts inspections, tests raw materials, and approves or rejects materials based on quality standards.
– Warehouse Personnel: Handles the receipt, storage, and quarantine of raw materials pending inspection results.
– Production Team: Uses only approved materials for manufacturing processes.
– Supplier Quality Team: Reviews and updates supplier qualifications to ensure consistent material quality.

4) Procedure

4.1 Material Receipt
4.1.1 Documentation Verification:
– Verify the purchase order (PO), certificate of compliance (CoC), and material safety data sheet (MSDS).
4.1.2 Visual Inspection:
– Check for visible defects, damage, or contamination during transit.
– Ensure the packaging is intact and labeled correctly.
4.1.3 Quarantine:
– Segregate received materials in the quarantine area until inspection and approval.

4.2 Inspection and Testing
4.2.1 Sampling Procedure:
– Perform sampling based on the sampling plan (e.g., ANSI/ASQ Z1.4).
– Ensure samples represent the entire batch.
4.2.2 Physical Testing:
– Verify physical properties such as dimensions, weight, and surface finish against specifications.
4.2.3 Chemical Testing:
– Test for material composition using techniques like spectroscopy, chromatography, or other relevant methods.
4.2.4 Functional Testing:
– Conduct performance tests to ensure materials function as required.
4.2.5 Documentation Review:
– Verify all supplied documentation (e.g., CoC, MSDS) against procurement requirements.

4.3 Approval Process
4.3.1 Inspection Report Generation:
– Document test results in a material inspection report.
– Include photographs, test values, and remarks for deviations.
4.3.2 Decision Making:
– Approve materials meeting all criteria.
– Reject materials that fail to meet specifications, and document reasons.
4.3.3 Labeling:
– Tag approved materials with an “Approved” label for storage and use.
– Clearly mark rejected materials as “Rejected” and move them to the designated area.

4.4 Storage and Traceability
4.4.1 Storage of Approved Materials:
– Transfer approved materials to the designated storage area with proper environmental controls (e.g., temperature, humidity).
4.4.2 Traceability:
– Assign batch numbers or IDs for traceability throughout the manufacturing process.
4.4.3 Reinspection:
– Perform periodic reinspection of materials if storage exceeds defined limits.

4.5 Handling Rejected Materials
4.5.1 Segregation:
– Store rejected materials separately to prevent accidental use.
4.5.2 Disposition:
– Initiate corrective actions, return materials to the supplier, or dispose of them per waste management protocols.
4.5.3 Supplier Feedback:
– Inform the supplier of quality issues and request corrective actions.
