Oleanolic acid price manufacturers

When sourcing Oleanolic Acid, the price is primarily driven by purity levels (typically 98% HPLC) and the extraction source (e.g., Olea europaea or Ligustrum lucidum). Buyers must verify the assay method used, as HPLC is the industry standard for accuracy. Ensure the product meets USP or EP pharmacopoeia standards if intended for pharmaceutical use. Additionally, check for residual solvents, heavy metals (Pb, As, Hg), and microbial limits to ensure the extract is safe for high-end formulations.

Advanced extraction methods like Supercritical CO2 extraction or ultrasonic-assisted extraction may result in a higher unit price but offer higher bio-activity and lower solvent residue. From a compliance perspective, suppliers holding GMP (Good Manufacturing Practice), ISO 22000, or HACCP certifications often command a premium because they guarantee batch-to-batch consistency and traceability, which are critical for international regulatory approval.

Oleanolic Acid is widely used in pharmaceuticals for hepatoprotective effects, in cosmetics for anti-inflammatory and anti-aging properties, and in health supplements. For cosmetic applications, solubility and color (white to off-white powder) are vital functional requirements. If the price seems unusually low, it may indicate a lower mesh size (particle size) or inferior solubility, which can affect the stability of your final product formulation.

The primary risk is Customs clearance failure due to improper documentation. Always ensure the supplier provides a Certificate of Analysis (COA), Material Safety Data Sheet (MSDS), and a Technical Data Sheet (TDS). For cross-border transactions, use Made-in-China.com's secured payment services to mitigate financial risk and ensure the goods match the agreed-upon specifications before final payment release.

To secure competitive pricing, discuss Annual Purchase Agreements rather than one-off spot buys; suppliers often offer 10-20% discounts for volume commitments. For security, prioritize Audited Suppliers on Made-in-China.com, as these companies have undergone third-party verification of their manufacturing facilities. Always request a pre-shipment sample from the actual production batch to conduct independent lab testing.

Oleanolic Acid is sensitive to light, heat, and moisture. Ensure the packaging consists of double-layer plastic bags inside fiber drums with vacuum sealing. For international shipping, specify cool and dry storage conditions in the Bill of Lading. When shipping to regions with strict botanical import laws, confirm the HS Code (typically 2916.39) and ensure the supplier provides a Phytosanitary Certificate if required by your local customs authority.
