01 / Define material identity
Confirm botanical name, plant part, origin, extraction ratio or marker assay, solvent and carrier where relevant. A product name alone is not a complete specification.
Quality & Documentation
Agree the specification before the purchase
For a concrete example of why identity, grade and screening need different evidence, read our saffron procurement research guide.
A useful quality review connects the proposed ingredient, its manufacturing site, the test methods and the batch documents. Request a representative COA for initial review, then agree what must accompany the actual shipment.
02 / Set acceptance criteria
Agree identity, assay, physical properties and relevant contaminant limits for your application and market. Confirm analytical methods and reporting units; include microbiology, metals, pesticides or residual solvents where required.
03 / Review COA & samples
Distinguish a representative COA from a batch-specific COA. Check product code, lot number, dates, methods, limits and results. Evaluate the sample in your formulation; confirm whether it represents the supply batch.
04 / Check certificates
Request applicable certificates and verify issuer, site, product scope and validity. Certification does not replace batch acceptance testing or market-specific regulatory review.

Before ordering, confirm the batch COA, packaging, storage, shelf life, traceability information and any declarations needed for your market. Document which requirements are included in the quotation.
06 / Resolve questions before release
If a result, method or document does not meet the agreed specification, resolve it before shipment. Buyers should assess suitability and regulatory status for their final product and destination.
