5% fenbendazole

5% Fenbendazole is a broad-spectrum anthelmintic (dewormer) primarily used in veterinary medicine for livestock (cattle, sheep, swine) and poultry. Its main function is to interfere with the energy metabolism of parasites, effectively treating gastrointestinal roundworms, lungworms, and tapeworms. For B2B buyers, it is commonly sourced as a premix for animal feed or a water-soluble powder for mass administration in large-scale farming operations.

As a pharmaceutical product, compliance is non-negotiable. You must ensure the manufacturer holds a valid GMP (Good Manufacturing Practice) certification. Additionally, check for COA (Certificate of Analysis) for every batch to verify the active ingredient concentration. For international trade, ensure the product meets USP (United States Pharmacopeia) or BP (British Pharmacopoeia) standards, and verify if the supplier is registered with the local Ministry of Agriculture or equivalent regulatory body in the destination country.

Quality is determined by particle size (fineness) and solubility. For feed premixes, a uniform particle size is critical to ensure even distribution in the feed. You should request stability testing data to confirm the product remains effective under various storage temperatures and humidity levels. Always ask for a 3rd-party inspection report (such as SGS or Intertek) to validate the 5% concentration level before the balance payment is made.

Standard 5% Fenbendazole typically has a shelf life of 2 to 3 years if stored correctly. It must be kept in a cool, dry, and dark environment, away from direct sunlight and moisture. B2B buyers should ensure the packaging is hermetically sealed (usually in multi-layer bags or fiber drums) to prevent degradation during long-term sea freight and warehousing.

Veterinary drugs are highly regulated. The biggest risk is customs seizure due to lack of import permits or product registration in the destination country. Before ordering, confirm the HS Code (typically 300490) and consult with a professional customs broker. Ensure the supplier provides MSDS (Material Safety Data Sheet) and clear bilingual labeling that complies with your local regulations to avoid clearance delays.

To secure your investment, use Trade Terms like FOB or CIF and prioritize suppliers on Made-in-China.com who have undergone Audited Supplier verifications. Use secured payment methods that offer escrow-like protection. Never transfer full payment upfront to a new supplier; instead, negotiate a 30% deposit and 70% balance against the Bill of Lading (B/L) and successful quality inspection.

Price in the chemical industry is highly sensitive to raw material costs and order volume. For 5% Fenbendazole, the MOQ is usually 25kg (one drum). To get better pricing, offer a long-term procurement plan rather than a one-off purchase. You can often achieve a 10-15% discount by increasing the order to 500kg or 1 ton, as this reduces the supplier's per-unit packaging and logistics overhead.

While Fenbendazole is generally classified as non-hazardous for transport, it is vital to ensure moisture-proof packaging. Request the use of pallets and shrink-wrapping for sea freight to prevent drum damage. For urgent small batches, air freight is viable but requires a Non-Hazardous Chemical Appraisal Report to be accepted by airlines. Always include cargo insurance to cover potential losses during transshipment.
