The corporate quality page describes incoming-material control, GMP-based monitoring through production and distribution, and a standardized laboratory. These are company-reported capabilities; confirm the current scope, method and record for the product and lot you are buying.

Before accepting a certificate of analysis, identify the tested material, test stage, sample or batch identifier, date, method, units, acceptance criteria and issuing laboratory. Oil input results and finished-softgel results answer different questions.
| Question | What to check | Why buyers care |
|---|---|---|
| What material was tested? | Raw fish oil, bulk fill, in-process sample or finished softgel | A result from oil input alone does not establish the finished product result. |
| Does potency support the label? | EPA and DHA values, units, basis and calculation per capsule/serving | Prevents confusion between fish-oil weight and EPA/DHA delivered. |
| How was freshness assessed? | Peroxide value (PV), p-anisidine value (p-AV), TOTOX and method | Interpret each measure with its method, sample stage and agreed specification. |
| Which contaminants are in scope? | Requested heavy metals, dioxins/PCBs or other market/buyer panel | Requirements vary by destination, product, raw material and importer. |
| Is the record traceable? | Lot/batch ID, sampling date, report date, lab identity and revision | Connects the evidence to the shipment being evaluated. |
Ask your supplier to identify which records exist now, which are product-specific, and which are generated for the finished lot.
Do not infer a certificate’s scope from its logo. Confirm issuing organization, entity, site, activity and validity period against the current source.
