Why supplier qualification matters
Selecting a botanical extract supplier is a risk decision, not just a price decision. The same "ginger extract 5%" can differ in marker compound, assay method, contaminant profile and batch consistency. This guide lists what procurement, QA and R&D teams should verify before moving from sample to bulk.
1. Specification and assay method
- Confirm the marker compound and the assay method (HPLC or UV), not just the plant name and extraction ratio.
- A specification figure (e.g. "98% by HPLC") is only meaningful with its method. Ask which compound is measured and how.
- Check whether the specification is customizable and what grades are available.
2. Batch documentation
- A batch-specific COA for every lot — not a generic template.
- TDS and MSDS / SDS for handling, formulation and shipping.
- Ask for a sample COA before you order, and confirm Halal / Kosher / Non-GMO documentation availability per product.
3. Quality system and testing
- Quality and food-safety management (ISO 9001 / ISO 22000) with documentation available on request.
- Routine heavy metals, microbiology, and — where applicable — pesticide residue and residual solvents.
- Third-party testing available when your market requires it.
4. Traceability and manufacturing
- Is the supplier an actual manufacturer or a trader? An own factory means one less tier and traceable sourcing.
- Confirm raw-material origin, plant part used, and batch-level traceability.
5. Commercial fit
- MOQ, lead time, packaging options and a sample-to-bulk path so you don't re-qualify when scaling.
- Responsiveness: how fast can the supplier return a COA, MOQ and quote?
Quick checklist
- Marker compound + assay method confirmed
- Batch-specific COA, TDS, MSDS available
- ISO 9001 / ISO 22000 documentation on request
- Heavy metals + microbiology per batch
- Manufacturer (not trader), traceable origin
- MOQ, lead time and sample-to-bulk path clear
