• Verify affected lots: Match CoA lot number to your inventory and records.
• Assess impact: Compare revised test results/specifications to acceptance criteria for your application.
• Quarantine if needed: Quarantine product batches if revisions change suitability or safety.
• Document: Attach revised CoA to batch records, change control, and QC logs.
• Notify stakeholders: Inform lab managers, QA, and downstream users if the revision affects experiments, products, or regulatory filings.
• Retesting: Consider in-house verification testing if results are critical.
• Escalate: If update indicates nonconformity or safety concern, contact supplier for corrective actions, replacement lots, or return.
