Diclazuril

Diclazuril is a potent benzeneacetonitrile antiprotozoal agent. For commercial procurement, buyers should prioritize a purity level of ≥99% (HPLC). The product should appear as an off-white to pale yellow crystalline powder. It is critical to verify the melting point (typically 290°C to 295°C) and ensure that residual solvents and heavy metals comply with international pharmacopeia standards such as USP or EP.

Diclazuril is primarily used as a coccidiostat in the poultry and livestock industries to prevent infections caused by Eimeria species. Functional requirements include high stability in feed premixes and excellent dispersibility. Buyers must ensure the particle size is optimized for uniform mixing to prevent dosage fluctuations, which could lead to sub-therapeutic levels or toxicity.

As a veterinary pharmaceutical ingredient, the supplier must possess a GMP (Good Manufacturing Practice) certificate. Depending on the destination market, you may require a Certificate of Analysis (COA), a Material Safety Data Sheet (MSDS), and potentially a VMF (Veterinary Master File). For the EU market, compliance with FAMI-QS (Feed Additives and Pre-mixtures Quality System) is often a prerequisite.

Buyers should request stability testing data (both accelerated and long-term). Diclazuril is generally stable but light-sensitive; therefore, it must be stored in light-resistant, airtight containers. Ensure the supplier guarantees a shelf life of at least 24 to 36 months under standard storage conditions to minimize inventory depreciation risks.

Always request a pre-shipment sample from the same batch intended for the bulk order. Utilize third-party inspection services (such as SGS or Intertek) to conduct independent lab testing for active ingredient content and impurities before the final payment is released. Sourcing through reputable platforms like Made-in-China.com allows you to identify Audited Suppliers with verified production capabilities.

Focus on tiered pricing based on volume; for orders exceeding 500kg, aim for a 10-15% discount compared to sample prices. Negotiate payment terms that link the final 30-50% of payment to the successful passing of destination port quality inspections. Additionally, confirm if the supplier can provide customized packaging (e.g., 25kg fiber drums with double PE liners) to ensure transit safety.

Diclazuril is generally classified as non-hazardous for transport, but you must verify the HS Code (typically 2933.29) to determine specific import duties in your country. Ensure the Commercial Invoice and Packing List clearly state the 'Veterinary Use Only' status to avoid delays in customs clearance related to human pharmaceutical regulations. For shipping to regions with high humidity, specify the use of desiccants within the shipping container.

Use secure payment methods and consider trade insurance services provided by professional B2B platforms. Avoid direct wire transfers to private accounts. Verify the supplier's business license and export permits through the Made-in-China.com company profile to ensure they are a legitimate manufacturer or authorized exporter rather than an unregulated middleman.
