Traditional chinese medicine

Buyers must prioritize Geographical Indication (Daodi) herbs, which are grown in specific regions known for optimal soil and climate. Ensure the supplier provides Certificate of Analysis (CoA) for every batch, covering active ingredient concentration (e.g., ginsenosides for Ginseng). Physical inspection should focus on color, aroma, and dryness; herbs should be free from mold, sulfur-bleaching, and insect infestation. For processed herbs (Pian), verify the processing technique (Paozhi) aligns with Pharmacopoeia standards.

Compliance is the highest barrier in TCM trade. Products must meet heavy metal limits (Lead, Cadmium, Mercury, Arsenic) and pesticide residue standards (e.g., USP <561> or EU regulations). Ensure the manufacturer holds GMP (Good Manufacturing Practice) certification. For finished products like granules or capsules, check for ISO 18665:2015 standards. Additionally, verify if the species is listed under CITES (Convention on International Trade in Endangered Species) to avoid legal seizures.

For extracts, specify the extraction ratio (e.g., 5:1 or 10:1) or the standardized percentage of marker compounds. Ensure the solvent used is food-grade (typically water or ethanol) and that residual solvent levels are within safe limits. For granules, check for solubility, particle size consistency, and moisture content (usually <5%) to ensure a long shelf life and effective dissolution.

TCM is highly sensitive to humidity and temperature. Specify vacuum packaging or moisture-proof foil bags for bulk herbs. For long-distance cross-border shipping, use desiccants and consider temperature-controlled containers if shipping sensitive extracts. Ensure the expiry date is clearly marked and that the product has undergone accelerated stability testing to guarantee potency for at least 24 months.

The primary risks include Customs Rejection due to non-compliant labeling or prohibited ingredients, and Quality Inconsistency between samples and bulk orders. To mitigate this, use third-party inspection services (like SGS or Intertek) to test for heavy metals and pesticides before the balance payment is made. Always source from reputable platforms like Made-in-China.com to verify supplier legitimacy.

Focus on volume-based pricing tiers and long-term supply stability. Since TCM prices fluctuate based on harvest seasons, consider annual fixed-price contracts to hedge against market volatility. Negotiate for flexible MOQs on trial orders but commit to larger volumes for customized formulations. Request transparency in the supply chain, specifically the origin of the raw herbs.

Always use Secure Payment methods and formal Proforma Invoices (PI) that detail every specification, including moisture levels and microbial limits. Ensure the contract includes a quality claim clause allowing for returns or discounts if third-party lab results fail to meet agreed-upon standards. Verify the supplier's Export License specifically for medicinal products.

For high-value extracts or small batches, Air Freight is preferred to minimize exposure to humidity. For bulk raw herbs, Sea Freight is cost-effective, but you must use High-Cube (HC) containers with ventilation or moisture-absorbing poles. Ensure all wooden pallets are ISPM 15 heat-treated to pass phytosanitary inspections at the destination port.
