Clopidol

Clopidol (3,5-Dichloro-2,6-dimethyl-4-pyridinol) is a potent coccidiostat. B2B buyers should ensure the product meets USP (United States Pharmacopeia) or EP (European Pharmacopoeia) standards. The purity (assay) should be ≥98% on a dried basis. Key physical properties to verify include particle size (fineness), as smaller particles ensure better distribution in feed premixes, and loss on drying (moisture content), which should typically be ≤0.5% to prevent caking and degradation.

As a veterinary pharmaceutical additive, Clopidol requires strict regulatory compliance. Suppliers must provide a GMP (Good Manufacturing Practice) certificate to ensure quality consistency. For entry into international markets, look for FAMI-QS (Feed Additive and Pre-Mixture Quality System) or ISO 22000 certifications. Additionally, a comprehensive COA (Certificate of Analysis) for every batch and a Safety Data Sheet (SDS/MSDS) are non-negotiable for customs clearance and safety handling.

Clopidol is primarily used in the poultry industry to prevent coccidiosis caused by Eimeria species. It is most effective when used prophylactically (preventative) rather than curatively. The standard inclusion rate in complete feed is usually 125 mg/kg (125 ppm). Buyers must verify the withdrawal period (typically 5 days before slaughter) to ensure the final meat product complies with Maximum Residue Limits (MRLs) set by local food safety authorities.

Clopidol is generally stable but sensitive to extreme conditions. It should be stored in tightly sealed, light-resistant containers in a cool, dry, and well-ventilated area. When sourcing, confirm the shelf life, which is usually 24 to 36 months. Buyers should request information on packaging integrity, such as the use of double-layer PE bags inside fiber drums, to prevent moisture absorption during long-distance sea freight.

To ensure transaction security, utilize Trade Assurance services on Made-in-China.com, which protect payments until delivery is confirmed. Always conduct third-party pre-shipment inspections (such as SGS or Intertek) to verify that the chemical composition matches the agreed specifications. Avoid making full payments upfront; a standard 30% deposit and 70% against the Bill of Lading (B/L) is a common and safer practice for verified suppliers.

When negotiating with manufacturers, focus on volume-based pricing tiers. For orders exceeding 1,000kg (1 ton), buyers can typically negotiate a 5-10% discount. Discuss long-term supply contracts to hedge against price volatility in raw chemical materials. Additionally, request free samples (50-100g) for lab testing before committing to a bulk order to ensure the product's efficacy in your specific feed formulation.

Clopidol is not classified as a highly dangerous good, but it must be handled as a chemical. Ensure the supplier provides a 'Certificate for Safe Transport of Chemical Goods' for air or sea freight. For shipping to regions with high humidity, specify the use of pallets with shrink-wrap and desiccants inside the container to maintain product dryness. Always clarify the Incoterms (e.g., FOB vs. CIF) to understand exactly where the risk transfers from the seller to the buyer.

Buyers must stay informed about anti-dumping duties and import tariffs specific to veterinary medicines in their country. Check if your country requires an Import License for Veterinary Drugs. Ensure the supplier is capable of providing a Certificate of Origin (CO), such as Form E or Form F, which can significantly reduce or exempt import duties under various Free Trade Agreements (FTAs).
