| 1 | Product identity and specification | Confirm the material is nervonic acid (cis-15-tetracosenoic acid; C24:1 n-9) and agree on the form supplied, such as an oil, concentrate, or isolated fatty acid. Set acceptance limits in the purchase specification rather than assuming a universal commercial grade. | Signed product specification; batch-specific certificate of analysis (CoA); analytical method and results for identity, assay, and fatty-acid profile. |
| 2 | Analytical capability | Check that the supplier can identify and quantify nervonic acid within a fatty-acid profile. Gas chromatography with a suitable detector is commonly used for fatty-acid analysis after derivatization; confirm method suitability, validation, and reporting basis. | Method summary; representative chromatogram; reference-standard information; laboratory quality documentation; details of any subcontracted testing. |
| 3 | Raw-material origin and traceability | Establish the botanical or other raw-material source, country of origin, processing site, and traceability from incoming material to finished batch. Ensure the declared source matches the product specification and intended market requirements. | Raw-material declaration; origin and processing-flow information; lot-coding procedure; traceability or mass-balance records; supplier-change notification policy. |
| 4 | Quality and food-safety systems | Assess controls relevant to the intended use and manufacturing process. ISO 22000 or FSSC 22000 certification indicates a food-safety management system; ISO 9001 concerns quality management. Neither certificate alone proves that a specific product meets buyer specifications. | Current certificates with scope and site details; audit summary; HACCP or hazard-control information where applicable; corrective-action process. |
| 5 | Contaminant and compliance controls | Identify risks based on the raw material, process, destination country, and end use. Agree on applicable limits and test plans for relevant contaminants; legal requirements differ by jurisdiction and product category. | Risk-based contaminant testing; compliance declarations for the target market; allergen and GMO statements where relevant; documentation supporting any restricted-substance claims. |
| 6 | Stability and packaging | Because nervonic acid is an unsaturated fatty acid, review how the supplier controls exposure to oxygen, heat, and light. Confirm packaging compatibility, storage conditions, and the basis for the stated shelf life. | Stability or shelf-life data; packaging specification; storage and transport instructions; oxidation-related test results if included in the agreed specification. |
| 7 | Regulatory and document readiness | Check whether the supplier can provide documents needed for the destination market and intended application. Regulatory status can depend on the ingredient source, manufacturing process, product claims, and use; do not treat a general statement as market authorization. | Product specification; CoA; safety data sheet where applicable; origin documents; export documents; market-specific declarations reviewed by the buyer’s regulatory team. |
| 8 | Capacity and supply continuity | Validate available production capacity, lead times, minimum order quantities, seasonal exposure of the raw material, and contingency plans. These are supplier-specific commercial facts and should be confirmed directly. | Written capacity and lead-time confirmation; forecast and allocation policy; business-continuity plan; disclosure of critical single-source dependencies. |
| 9 | Shipment and import capability | Confirm the supplier’s experience with the buyer’s destination, agreed Incoterms, export documentation, packaging units, and temperature or handling requirements. Verify shipping details before placing an order. | Sample shipping document set; packaging and pallet details; proposed Incoterm; export references or forwarder coordination process; shipment-condition instructions. |
| 10 | Commercial terms and change control | Compare quoted price on an equivalent basis, including assay, form, packaging, shipment terms, and payment conditions. Require advance notice and approval for material changes to source, process, specification, or manufacturing site. | Formal quotation; agreed specification and quality agreement; change-control clause; complaint and recall procedures; sample-retention policy. |
