Define what 50/20 means in your specification
Write the target as EPA 50% and DHA 20%, then state the units, assay basis, analytical method and acceptance range. Confirm whether the remaining omega-3 fraction matters to the formula or label. A shorthand product name should not replace a controlled specification.
Select molecular form separately
Ask whether the required form is EE, TG or rTG, or whether alternatives may be evaluated. Request separate quotations and documents for each form. Do not compare a 50/20 offer with another profile or form and treat the quoted price per kilogram as a like-for-like comparison.
If the form is flexible, model each candidate in the finished dose. Review fill mass, capsule dimensions, serving count, sensory criteria and process compatibility with the formulation and manufacturing teams.
Review quality and batch evidence
Agree oxidation limits and methods for PV, p-anisidine value and TOTOX. Define contaminant and microbiology requirements for the intended product and destination market. Check whether reported results are specific to the offered batch and whether the COA uses the agreed product identity and specification revision.
For a sample, record the lot or sample code, storage condition and intended application. Approval should include the criteria for the commercial batch, not only the development sample.
Compare delivered cost, not only price per kilogram
Build a cost comparison using the amount of ingredient needed to deliver the target EPA and DHA, plus pack size, freight, insurance, import charges, testing and expected production yield. Include any additional requirements for documents, packaging or handling. A more concentrated profile can change dose economics, but the actual comparison depends on the formula and supplier quote.
50/20 fish oil buyer checklist
- EPA 50% / DHA 20% values, units, assay basis and limits are explicit.
- Molecular form is specified per quote and supported by documents.
- PV, p-anisidine value, TOTOX and other quality criteria are agreed.
- The sample is tested in the intended dosage form.
- Pack size, storage, shipment and destination-market files are confirmed.
- Cost is compared per usable dose under the same commercial assumptions.
Information to include in the RFQ
Send the 50/20 target, molecular form, application, sample quantity, annual volume, quality limits, packaging preference, destination and documents required. Ask suppliers to identify assumptions and exclusions so the resulting offers can be compared accurately.
