Propiconazole manufacturers

Propiconazole is a systemic triazole fungicide. For B2B procurement, the Technical Grade (TC) typically requires a purity of ≥95%. Key specifications include moisture content (≤0.5%), acidity (calculated as H2SO4 ≤0.3%), and acetone insolubles. If purchasing formulations, common concentrations include 250g/L EC (Emulsifiable Concentrate) or 50% WDG (Water Dispersible Granules). Buyers must verify the isomer ratio, as the biological activity depends on the specific cis-trans configuration.

As a chemical pesticide, Propiconazole must adhere to strict regulatory frameworks. Suppliers should provide FAO (Food and Agriculture Organization) specifications and a valid MSDS (Material Safety Data Sheet). For entry into the EU, REACH registration is essential. In the US, EPA registration numbers are required. Ensure the supplier holds ISO 9001 for quality management and ISO 14001 for environmental management, as chemical synthesis is subject to rigorous environmental audits.

Propiconazole is widely used for its protective and curative actions. It is highly effective against Ascomycetes, Basidiomycetes, and Deuteromycetes fungi. Common applications include treating rust, powdery mildew, and leaf spot in crops like wheat, rice, peanuts, and bananas. Its systemic properties allow it to be absorbed by the roots or leaves and translocated acropetally, providing long-lasting residual activity and resistance to rain wash-off.

The price of Propiconazole is heavily influenced by the cost of raw materials like 1,2-pentanediol and bromine. Buyers should monitor environmental protection policies in China, as factory shutdowns can lead to sudden supply shortages. To optimize costs, consider bulk purchasing in 200L drums or 1000L IBC tanks, which can reduce unit costs by 10-15% compared to small retail packaging. Always factor in the Total Cost of Ownership (TCO), including specialized hazardous goods logistics and customs clearance fees.

Propiconazole is classified as Class 9 Hazardous Goods (Environmentally Hazardous Substance) for international transport (UN 3082 or UN 3077). You must ensure the supplier provides a Dangerous Goods Certificate and uses UN-approved packaging. For shipping to regions like Southeast Asia or Africa, FCL (Full Container Load) is recommended to prevent cross-contamination. Always verify the port's capability to handle hazardous chemicals before booking freight.

To ensure security, use Trade Assurance services on Made-in-China.com. Never release full payment until a Pre-shipment Inspection (PSI) is conducted by a third party like SGS or Intertek. The inspection should include HPLC (High-Performance Liquid Chromatography) testing to verify the active ingredient content. Requesting a 100g-200g sample for lab analysis before placing a bulk order is a standard industry precaution.

Focus on long-term supply stability rather than just the lowest price. Negotiate for staggered delivery schedules to manage inventory costs. Ask for transparency in the production cycle—reputable manufacturers will share their production schedules. For large orders, negotiate payment terms such as L/C (Letter of Credit) to protect your capital, and seek volume-based rebates if annual targets are met.

Be aware of Anti-dumping duties that some countries impose on Chinese chemical exports. Check the MRL (Maximum Residue Limit) regulations in your target market; if the Propiconazole is used on export crops, it must meet the destination country's food safety standards. Ensure all labels are translated into the local language and include mandatory safety warnings and local emergency contact information as required by law.
