Quick Answer: Before choosing a supplement OEM or botanical extract supplier, buyers should verify raw material identity, active marker logic, batch COA, contaminant testing, microbiology, packaging controls and export documentation. A certificate alone is not enough; the audit should connect test methods, batch numbers and finished-product requirements.
What a B2B Buyer Should Request
| Document / Test | Why It Matters |
|---|---|
| Specification sheet | Defines ingredient identity, active marker, appearance, limits and storage requirements |
| Batch COA | Connects a specific batch to actual test results rather than generic claims |
| HPLC / UV-Vis / identity method | Clarifies how standardized botanical extracts or active markers are verified |
| Heavy metals and microbiology | Supports buyer review for target-market safety expectations |
| Packaging specification | Shows bottle, pouch, desiccant, label and carton assumptions |
| Export document pack | Prepares invoice, packing list, COA and shipment support before deadlines |
Standardized Extracts vs. Ratio Extracts
Ratio extracts can be useful, but they do not automatically guarantee a quantified active marker. For potency-sensitive formulas, buyers should request standardized extracts and appropriate analytical methods. See: Standardized Botanical Extracts vs. Ratio Extracts.
Factory Audit Questions
- Can the supplier connect each COA to a batch number and production record?
- Which tests are batch-specific and which are specification references?
- How are micro-dosed ingredients blended and checked?
- How are moisture-sensitive ingredients stored and packaged?
- What documentation is prepared for export and distributor review?
