By following these steps, you create a reliable system for product inspection and quality control. You minimize risks, ensure compliance, and lay the groundwork for successful production.

Accept or Reject Materials

Criteria for Acceptance

You need clear criteria to decide if a batch of raw materials is suitable for production. During raw material inspection, you should confirm that analytical methods are appropriate for the material type. This step builds confidence in your data and ensures your system performs as expected. You must also verify process consistency and reproducibility. Meeting these requirements helps you comply with GMP, ISO, and HACCP standards. Ensuring product safety, efficacy, and compliance reduces long-term operational risks.

If you accept substandard materials, you risk product inspection failures and costly recalls. For example, brittle plastics may crack under pressure, or metal parts may corrode due to poor-quality alloys. These issues can cause products to fail prematurely and damage your reputation.

Handling Rejected Materials

When you reject a batch during inspection of raw materials, you must follow strict procedures to ensure safety and compliance. Start by tagging rejected materials with a clear “REJECTED” label. Complete a Material Rejection Report that includes the material name, batch or lot number, quantity, reason for rejection, and approval for destruction. Quality assurance reviews the report and authorizes destruction.

Each team has a specific role in this process:

You should use the recommended destruction method for each material type. For example, incinerate raw materials or use chemical degradation. Shred or recycle packaging materials if they are clean. Always use personal protective equipment and follow environmental regulations.

Tip: Prevent mix-ups by clearly labeling and isolating all rejected materials before destruction. This practice supports effective product inspection and quality control throughout your pre-production inspection process.

Pre-Production Product Inspection

Move Approved Materials to Storage

You complete the final step of raw material inspection by moving approved materials to designated storage areas. This step ensures that only materials meeting your product inspection criteria enter the production line. You must verify that each batch matches your specifications and documentation before storage. Assign clear labels and use secure storage zones to prevent mix-ups. By following this process, you maintain a controlled environment and support quality control.
