Use this checklist to evaluate COA completeness, lot identity, and interpretation boundaries for research workflows.
Match the lot or batch identifier on the product listing with the identifier shown in the COA file. A mismatch is a hard stop for procurement.
Keep archived copies of referenced COAs with date stamps in your internal records for traceability audits.
COAs should disclose test method context, reporting format, and any boundaries on interpretation. Missing method context makes result comparisons unreliable.
When possible, compare monthly reports for the same material to identify variance before adding inventory to active protocols.
Record whether each lot is approved, conditionally approved, or rejected, plus the reason code. This discipline supports reproducibility and faster incident review.
Treat COA review as part of your standard research QA workflow, not a one-time checkbox.
