Research Product COA Verification Checklist
Compare the document, product record, lot, methods, results, package, and open questions in one repeatable review.
What the checklist covers
- Document identity and lot linkage
- Cat. No., product name, form, strength, and package consistency
- Method, specification, reported result, and units
- Packaging, label, storage, and receiving links
- Supplier questions and PASS / HOLD / ESCALATE decision record
Review the document in eight steps
Use the original report, the offered product record and the available label or lot record side by side. Record what each source actually says; leave missing fields marked as unconfirmed.
Identify the document and issuer
Record the report number, named laboratory or issuer, date and version shown. Keep the original file and its source. Ask the issuer to explain an unreadable, incomplete or inconsistent record.
Match the exact material name
Compare the full name and any stated chemical form or blend composition. Record a CAS number only if provided. A familiar abbreviation or similar name alone does not establish a match.
Compare the specification and package
Copy the amount or volume, units and package quantity as written. Keep the amount per container separate from the number of containers. Ask about any mismatch between the offer, label and report.
Check the sample and lot identifiers
Record the sample identifier and lot number exactly. Compare them with the lot being offered. A catalog number identifies a catalog entry and does not replace a lot number.
Read the test and method fields
For each reported test, note the method and any stated acceptance limit. If a method or criterion is absent, mark that gap and ask for clarification rather than supplying your own.
Keep results with their units and limits
Copy each result with its units, qualifiers and stated detection or reporting limits. Do not treat one reported percentage as evidence for a different test or assume that unreported properties were checked.
Confirm the connection to the current material
Request the available current label, lot record and corresponding report. Check the offered package against those records. A historical sample report or catalog illustration does not establish the identity of the current lot.
Record open questions and the review outcome
List matched fields, missing evidence and conflicts, with the source and review date. Keep unresolved items on hold for clarification by the issuer or supplier; record any escalation and the response received.
This review organizes evidence; it does not authenticate a report or establish a product’s approval, legal status or suitability. A report applies to the sample and scope it identifies, not automatically to other lots.
