Traditional medicine manufacturers

Buyers must prioritize suppliers that adhere to GMP (Good Manufacturing Practice) and GAP (Good Agricultural Practice). Ensure the products have COA (Certificate of Analysis) for every batch, detailing active ingredient concentration (e.g., ginsenosides for ginseng), moisture content, and the absence of heavy metals (Lead, Arsenic, Mercury) and pesticide residues.

Request DNA barcoding or HPTLC (High-Performance Thin Layer Chromatography) fingerprinting reports to confirm the specific plant species. This prevents adulteration or the accidental substitution of similar-looking but ineffective or toxic botanical species.

Inquire about extraction methods such as Supercritical CO2 Extraction or Low-Temperature Spray Drying, which preserve thermosensitive bioactive compounds. For powders, check the mesh size (typically 80-120 mesh) to ensure optimal bioavailability and solubility in final formulations.

For the US market, products must comply with FDA 21 CFR Part 111 (Dietary Supplements). For the EU, adherence to EFSA (European Food Safety Authority) regulations and Novel Food status checks is mandatory. Always ensure the supplier provides Phytosanitary Certificates required for customs clearance of plant-based materials.

Implement a pre-shipment inspection (PSI) by a third party like SGS or Intertek. Use vacuum packaging or moisture-proof aluminum foil bags with desiccant to prevent mold growth and oxidation during long-term sea freight.

Focus on long-term stability rather than just the lowest price. Ask for tiered pricing based on active ingredient purity. Request a trial order (MOQ) to test the consistency of the extract before committing to a full container load, and use Diamond Member status on Made-in-China.com to identify verified manufacturers.

Strictly check the CITES (Convention on International Trade in Endangered Species) list. If a product (like certain wild orchids or agarwood) is listed, you must obtain specific export/import permits. Failure to do so will lead to seizure of goods and heavy fines at customs.

Utilize Secured Payment services provided by the platform to ensure funds are only released after the Bill of Lading (B/L) is verified. For large contracts, include a quality claim clause that specifies the arbitration process if the lab results at the destination do not match the supplier's COA.
