Centella

When sourcing Centella Asiatica for cosmetic or pharmaceutical use, you must prioritize the Total Triterpenes content. Specifically, look for standardized extracts containing Madecassoside, Asiaticoside, Madecassic Acid, and Asiatic Acid. For high-end skincare formulations, a purity level of 95% or higher for individual compounds like Madecassoside is often required to ensure anti-inflammatory and collagen-synthesis properties.

Ensure the supplier provides a Certificate of Analysis (COA) for every batch. Key parameters must include heavy metal limits (Lead <10ppm, Arsenic <2ppm), microbial counts (Total Plate Count <1000 cfu/g), and pesticide residue analysis. For international trade, verify that the product complies with INCI (International Nomenclature Cosmetic Ingredient) standards and has MSDS (Material Safety Data Sheet) documentation for shipping.

Centella is typically traded in three forms: Dried Raw Herb, Powdered Extract (Standardized), and Liquid/Glycerin Extracts. Powdered extracts are the most cost-effective for cross-border shipping due to their long shelf life (24 months) and high concentration, which reduces logistics costs per active unit compared to liquid forms.

The particle size (mesh size) and the solvent used for extraction (water vs. ethanol) significantly impact solubility. For clear serum formulations, request 100% water-soluble grades with a mesh size of 80-100. If the extract is intended for oil-based creams, ensure the lipophilic balance is compatible with your base formula.

The biggest risk is adulteration or species substitution. Some low-cost suppliers may mix Centella with similar-looking botanical fillers. To mitigate this, use Made-in-China.com's 'Audited Supplier' reports to verify the manufacturer's production capacity and request HPLC (High-Performance Liquid Chromatography) testing results to confirm the fingerprint of the active ingredients.

Prices for Centella fluctuate based on harvest seasons and active ingredient concentration. For bulk orders exceeding 100kg, you can typically negotiate a 15-20% discount. Always ask for tiered pricing based on purity levels (e.g., 10% vs 80% purity) to find the most economically feasible option for your specific product line.

Centella extracts are hygroscopic (absorb moisture) and light-sensitive. Ensure the supplier uses double-layer PE bags inside fiber drums with vacuum sealing. During transit, specify cool, dry storage conditions. For cross-border logistics, choose Air Freight for high-purity extracts to minimize exposure to extreme temperatures in shipping containers.

Utilize Secure Payment services provided by reputable platforms like Made-in-China.com to ensure funds are only released upon proof of shipment. Additionally, check your local Customs Tariff (HS Code 130219) for botanical extracts, as some regions impose specific Phytosanitary Certificate requirements for plant-derived materials.
