Start with sample identity
Confirm that the document identifies the offered product, supplier, sample/batch number, sampling date and tested material. Raw oil, bulk softgel fill and finished softgels are different test subjects.
Check EPA and DHA reporting basis
Confirm the report lists EPA and DHA separately, with units and basis. Match the laboratory result to the label claim per capsule or serving. Do not infer EPA/DHA amount from total fish oil weight.
Read oxidation results with their method and units
PV, p-AV and TOTOX each describe a different part of oxidation evaluation. Check method references, unit, sample stage and the agreed specification. GOED’s published oxidation-control guidance provides an industry reference for covered EPA/DHA oils and products; the cited values are not a substitute for your product and lot records.
Confirm contaminants and destination scope
Ask which contaminants were tested, method, limit and reporting basis. Confirm that the requested market or importer panel is covered. One generic COA may not answer every market-specific question.
Check document authority and traceability
Verify issuing laboratory/entity, report date, authorized sign-off when applicable, revision, batch identification and consistency with the purchase specification. If a certificate is used to support a facility claim, check its issuer, scope, legal entity, site and validity.
