Praziquantel

Praziquantel is a critical anthelmintic medication. B2B buyers must ensure the product complies with international pharmacopoeia standards such as USP (United States Pharmacopeia), BP (British Pharmacopoeia), or EP (European Pharmacopoeia). Key technical parameters include a purity level (Assay) of 98.5% to 101.0%, a melting point between 136°C and 141°C, and strict limits on heavy metals (≤20ppm) and related impurities (individual impurity ≤0.2%). Always request a Certificate of Analysis (COA) for every batch.

Due to its use in human and veterinary medicine, suppliers must hold a GMP (Good Manufacturing Practice) certificate. For entry into regulated markets, look for suppliers with a CEP (Certificate of Suitability) or a DMF (Drug Master File) number. Additionally, ISO 9001 for quality management and ISO 14001 for environmental management are strong indicators of a professional manufacturer.

Praziquantel is sensitive to light and moisture. It should be packed in double-layer PE bags inside fiber drums (usually 25kg/drum). The packaging must be light-resistant and hermetically sealed. Storage should be in a cool, dry, and well-ventilated area away from direct sunlight. Ensure the supplier provides MSDS (Material Safety Data Sheets) for proper handling instructions.

It is primarily used as an Active Pharmaceutical Ingredient (API) for formulating treatments against schistosomiasis, liver flukes, and tapeworm infections. It is widely sourced for both human pharmaceutical production and the veterinary medicine sector (especially for deworming pets and livestock). Buyers should specify whether they require Human Grade or Veterinary Grade as testing requirements may differ.

The primary risks include quality inconsistency between samples and bulk orders, regulatory seizure due to improper documentation, and volatile shipping costs. To mitigate these, use third-party inspection services (like SGS or Intertek) before shipment and ensure all customs HS codes (typically 2933.79) are correctly declared to avoid delays.

Utilize secure payment methods and platforms. We recommend sourcing through Made-in-China.com, utilizing their Secured Trading Service or Audit Reports to verify the supplier's physical existence and production capacity. Avoid direct wire transfers to unknown accounts without a verified proforma invoice and trade contract.

Praziquantel is generally classified as non-hazardous for transport, but this must be confirmed by a DGM report (Identification and Classification Report for Air/Sea Transport of Goods). Buyers must check their local import permit requirements for pharmaceutical substances. For shipping, FOB (Free On Board) is recommended for buyers with their own logistics partners, while CIF (Cost, Insurance, and Freight) is suitable for those wanting the supplier to handle the risks until the destination port.

Negotiation should be based on volume and long-term commitment. For orders exceeding 500kg to 1 ton, buyers can typically negotiate a 10-15% discount. Discussing payment terms (e.g., 30% deposit, 70% against BL copy) rather than 100% upfront can also improve your cash flow and reduce risk.
