Fungicide metiram manufacturers

Metiram is a dithiocarbamate fungicide typically sold as a Water Dispersible Granule (WDG) or Wettable Powder (WP). You must verify the active ingredient (AI) content, commonly 70% or 80%. Ensure the product has excellent suspensibility (≥80%) and a fast wetting time (≤60 seconds) to prevent clogging spray nozzles. Additionally, check the zinc content, as Metiram is a complex of zineb and polyethylene thiuram disulfide, providing essential micronutrients to crops.

Metiram is a broad-spectrum, contact fungicide with protective action. It is highly effective against Downy Mildew, Apple Scab, Rust, and Late Blight. It is widely used in viticulture (grapes), pome fruits (apples/pears), potatoes, and vegetables. Because it inhibits spore germination, it must be applied preventatively before the onset of disease symptoms for maximum efficacy.

Suppliers must provide a Certificate of Analysis (COA) for every batch. For international trade, ensure the product meets FAO (Food and Agriculture Organization) specifications. Depending on the destination, you may need EPA registration (USA), REACH compliance (EU), or specific pesticide registration certificates from the importing country's Ministry of Agriculture. Always request the Material Safety Data Sheet (MSDS) to ensure safe handling and transport.

Evaluate the cost per hectare rather than just the price per kilogram. High-quality WDG formulations may have a higher unit price but offer better solubility and lower dust levels, reducing waste and labor costs. For packaging, standard B2B sizes include 25kg fiber drums or 1kg/5kg aluminum foil bags packed in cartons. Ensure the packaging is UV-resistant and moisture-proof to maintain a shelf life of at least 2 years.

The biggest risk is regulatory seizure if the product is not registered in the destination country. Agrochemicals are highly regulated substances. Another risk is chemical degradation during transit if exposed to extreme heat or moisture. Always use reputable inspection services like SGS to verify the AI content before the balance payment is made.

Focus on long-term supply stability and registration support. Ask if the supplier can provide Data Packages (GLP reports) to assist with your local registration. Negotiate for tiered pricing based on annual volume rather than single orders. For first-time buyers, request a paid sample to conduct a lab analysis and field trial before committing to a full container.

Metiram is generally classified as Environmentally Hazardous Substance (UN 3077, Class 9) for sea transport. You must ensure the supplier provides a Dangerous Goods (DG) Certificate and uses IMO-compliant labeling. Shipping should be arranged in dry containers, away from heat sources and food products, to prevent cross-contamination.

Utilize Trade Assurance or Letter of Credit (L/C at sight) to protect your funds. Never transfer full payments to private accounts. Ensure the Proforma Invoice (PI) clearly states the purity level, batch number, and production date. For high-value orders, hiring a third-party auditor to visit the factory in China via Made-in-China.com's audited supplier service is highly recommended.
