Changsha Huir Biological-Tech Co., Ltd, located in Changsha, Hunan Province, China, offers Levodopa with a declared purity of 98 % and molecular formula C9H11NO4. The API is extracted from Mucuna pruriens seeds using solvent extraction and is intended for pharmaceutical manufacturing of anti‑Parkinson’s medicines. The listing specifies that the compound meets the requirements of pharmaceutical‑grade organic material. This product is positioned for bulk trade under cold‑chain conditions.
In the pharmaceutical industry, APIs of this class typically have an assay tolerance of ±0.5 % and moisture content below 0.5 % to ensure stability. Standard storage calls for temperatures between 2 °C and 8 °C, and shipments are normally packed in sealed stainless‑steel drums of 200 L capacity. Compliance with pharmacopeial standards such as USP is customary, and certificates of analysis are expected for each batch. Typical shelf life under recommended conditions is twenty‑four months.
Levodopa is primarily purchased by drug manufacturers, contract research organisations and formulators of neurological therapies. Prospective buyers should request the supplier’s full COA, GMP certification and details of the cold‑chain logistics before confirming an order. Lead times, payment schedules and Incoterms must be clarified directly with the supplier to ensure regulatory compliance.

When sourcing Levodopa, first confirm that the batch is accompanied by a full Certificate of Analysis, GMP certification and any applicable pharmacopeial compliance documents. Verify the declared 98 % purity and request assay and moisture test results to ensure the material meets your formulation specifications. These checks reduce the risk of receiving non‑conforming API material.
Discuss logistics by agreeing on Incoterms such as FOB or CIF, and ensure that the supplier can provide continuous temperature‑controlled transport between 2 °C and 8 °C. Ask for an estimated lead time based on current production schedules and confirm payment terms, whether by L/C, T/T or other methods, before finalising the contract. Clear agreement on these points helps avoid delays at customs and during warehouse receipt.
Plan for a third‑party pre‑shipment inspection that includes visual examination, assay verification and packaging integrity. Request the inspection report, along with the COA and any relevant certificates, to be attached to the shipping documents. Proper documentation and inspection records facilitate smooth customs clearance and assure product quality upon arrival.
