| Ingredient identity | Confirm that the product is nervonic acid or a clearly specified nervonic-acid-containing ingredient. Check the source material, ingredient form, and fatty-acid profile. | Product specification; source and process description; representative chromatogram; batch-specific certificate of analysis (CoA). | Names such as “nervonic acid,” “oil,” and “powder” do not by themselves establish equivalent composition or regulatory status. |
| Assay and fatty-acid profile | Review the declared assay or nervonic-acid content, the reporting basis, and the levels of other identified fatty acids. | Validated GC-FID or GC-MS method, appropriate reference standards, chromatograms, test results, and stated calculation basis. | A method should be suitable for the ingredient matrix. Compare results only when methods and reporting bases are comparable. |
| Contaminants and safety | Set risk-based limits for relevant contaminants, such as heavy metals, residual solvents, pesticides, and microbiological hazards, where applicable to the source and product. | Batch-specific results from a competent laboratory; methods, units, detection or quantification limits, and sampling details. | Applicable limits depend on the ingredient, intended use, and destination-market rules. Do not treat a generic “pass” statement as a substitute for results. |
| Oxidation and stability | For lipid-containing materials, assess oxidation risk and confirm that packaging and storage conditions protect product quality throughout the stated shelf life. | Relevant oxidation test results where appropriate; stability data; packaging specification; storage and transport instructions. | Test selection should suit the product form. Shelf-life claims should be supported by stability evidence. |
| Manufacturing controls | Assess the facility’s documented controls for supplier approval, process monitoring, sanitation, deviations, corrective actions, and product release. | Quality manual or audit summary; process flow; traceability and recall procedures; training records; change-control procedures. | ISO 9001, ISO 22000, HACCP, or other certifications may support an assessment, but their scope, validity, and relevance to the actual site and product should be checked. |
| Laboratory competence | Determine whether testing is performed in-house or externally, and whether the laboratory is competent for the specific methods used. | Laboratory name on records, method references, equipment and calibration controls, proficiency evidence, and relevant ISO/IEC 17025 accreditation scope where available. | Accreditation is scope-specific; verify that the listed method or test category is covered rather than relying on the accreditation logo alone. |
| Batch traceability | Require a unique lot number and the ability to trace the batch through raw materials, production, testing, and shipment. | Lot-specific CoA; production and packing dates; batch records; retained-sample policy; recall contact and procedure. | Confirm that the supplied lot matches the labels, shipping documents, and test report. |
| Documentation for export | Agree on the document set before shipment and ensure product descriptions and declared composition are consistent across records. | Commercial invoice, packing list, transport documents, CoA, specification, origin documentation where required, and safety data sheet where applicable. | Import documents and customs classification depend on the destination country, product form, and intended use. Confirm requirements with the importer or broker. |
| United States considerations | Determine whether the ingredient will be marketed as a food, dietary supplement, or another product category, and assess the obligations that apply to that use. | Product classification review; applicable facility and food-safety records; ingredient safety and regulatory assessment; compliant labeling review. | FDA food-facility registration, when required, is not FDA approval of a product. Dietary-supplement requirements, including any applicable new dietary ingredient notification, require product-specific assessment. |
| European Union considerations | Check the ingredient’s regulatory status for the intended food or supplement use before importing or placing it on the market. | Documented novel-food status assessment where relevant; applicable food-safety and labeling review; import and traceability records. | Novel Food status depends on the specific ingredient, production process, and use history. Consult current EU sources and competent authorities; do not assume an ingredient is authorized based on its name alone. |
| Labeling and claims | Check ingredient naming, composition statements, warnings, storage instructions, and any proposed nutrition or health claims against destination-market rules. | Draft label; specification-to-label comparison; legal or regulatory review; substantiation file for any permitted claims. | Claims and required label particulars vary by jurisdiction and product category. Supplier marketing materials do not establish that a claim is legally permissible. |
| Buyer qualification | Use a documented supplier-approval process before placing commercial orders, and define acceptance criteria in the purchase specification. | Questionnaire or audit; approved specification; sample evaluation; quality agreement; change notification and nonconformance procedures. | Requirements should be tailored to the buyer’s application and destination market.
