## Buyer Checklist
Professional market data infographic showing key trends and projections
- Define your ingredient specifications (active marker compounds, purity, heavy metals, microbial limits)
- Research manufacturers with relevant certifications (GMP, ISO 22000, FDA registered, HACCP)
- Request Certificates of Analysis (COA), specifications sheets, and safety data sheets (SDS)
- Verify third-party lab testing for contaminants (heavy metals, pesticides, microbes)
- Confirm minimum order quantities (MOQs) and lead times before negotiating
- Check whether the supplier handles export documentation, freight forwarding, and customs clearance
- Clarify packaging requirements (food-grade, moisture-barrier, label compliance for destination market)
- Negotiate Incoterms (EXW, FOB, CIF) and payment terms upfront

|--------|---------------------------|------------------------------|
| Price | Typically lower (factory direct) | Slight markup but reduced risk |
| MOQ | Higher (often 100–500 kg per SKU) | Can often aggregate across clients |
| Documentation | Supplier handles export docs only | Agent manages full export process |
| QC verification | Buyer arranges independently | Agent often arranges pre-shipment inspection |
| Communication | Direct with manufacturer | Managed through agent (may add delays) |
| Lead time | Shorter | Slightly longer due to intermediary |
| Regulatory support | Limited | Varies — some agents provide formulation input |
| Payment terms | Typically T/T 30–50% deposit | May offer open terms for established clients |
| Freight coordination | Buyer arranges from port of loading | Agent may include CIF/DDP options |
| Samples | Usually available before production | Agent can source samples from multiple factories |
| Risk | Higher without local knowledge | Lower with an experienced partner |
## FAQ Section
**Q: What certifications should a functional ingredient supplier in China have?**
A: At minimum, look for GMP (Good Manufacturing Practice), ISO 22000 or FSSC 22000, and FDA food facility registration. For botanicals, organic certification (USDA or EU) may be required. Third-party audits like SGS or Bureau Veritas add credibility.
**Q: How do I verify quality before placing a large order?**
A: Request samples from current production batches and have them tested by an independent third-party lab. Ask for a Certificate of Analysis showing active marker content, microbial results, and heavy metal testing. Some buyers commission a pre-shipment inspection service.
**Q: What are typical lead times for functional ingredients from China?**
A: Most orders ship within 2–4 weeks after order confirmation and payment. Air freight adds 1–2 weeks for delivery; sea freight 4–6 weeks. Some custom formulations or extracted ingredients may require 4–6 weeks for production.
**Q: Can I get small quantities for product development?**
A: Many manufacturers offer small-lot production for R&D and sampling purposes, though unit pricing will be higher. AICHENGFU can facilitate smaller runs through their network for product development stages before scaling to commercial volumes.
**Q: What documents do I need to import functional ingredients into the EU, UK, or US?**
A: You will need a Certificate of Analysis (COA), Certificate of Origin, commercial invoice, packing list, and Bill of Lading. For botanicals, a Phytosanitary Certificate may be required. Your supplier should provide these as part of standard export documentation.
