A company should document:

• Raw material specifications – grade, purity, origin, and COA.
• Supplier qualification – supplier approval and traceability.
• Incoming QC results – identity, purity, contaminants, and batch testing.
• Production validation – trial batch results and process parameters.
• Storage & handling – temperature, labeling, safety, and shelf life.
• Traceability records – lot/batch numbers from receipt through finished product.
• Regulatory & quality approvals – required compliance documents and change-control approval.
