Metribuzin

Metribuzin is a selective triazinone herbicide. For B2B procurement, the Technical Grade (TC) usually requires a purity of ≥95% or ≥98%. Formulated products commonly include 70% WDG (Water Dispersible Granules), 75% WP (Wettable Powder), or 480g/L SC (Suspension Concentrate). Buyers must verify the CAS No. 21087-64-9 and request a Certificate of Analysis (COA) for every batch to ensure the active ingredient concentration meets the label claim.

It is primarily used for pre-emergence and post-emergence control of broadleaf weeds and annual grasses. It is highly effective in crops such as potatoes, soybeans, tomatoes, sugarcane, and asparagus. Buyers should ensure the formulation matches the specific application method (e.g., soil-applied vs. foliar spray) and confirm the selectivity to avoid phytotoxicity in sensitive crop varieties.

As an agrochemical, Metribuzin must comply with the FAO (Food and Agriculture Organization) specifications. Suppliers should provide a Material Safety Data Sheet (MSDS) and a Safety Data Sheet (SDS) compliant with GHS standards. For cross-border entry, ensure the product is registered with the local Ministry of Agriculture in the destination country and check for ICAMA (Institute for the Control of Agrochemicals, Ministry of Agriculture) export certificates if sourcing from China.

Metribuzin is sensitive to moisture and light. Standard packaging includes 25kg fiber drums for TC or 1kg/5kg aluminum foil bags for WDG/WP. Ensure the packaging is UN-certified for hazardous goods (Class 9). Storage must be in a cool, dry, and well-ventilated warehouse, away from food, seeds, and fertilizers to prevent cross-contamination.

Always conduct third-party inspections (such as SGS or BV) before shipment to verify the active ingredient content and physical properties. Use Made-in-China.com to identify Audited Suppliers who have undergone rigorous on-site factory checks. Avoid deals that are significantly below the global market price, as this often indicates diluted or impure products.

Metribuzin is often classified as an Environmentally Hazardous Substance (UN 3077/3082, Class 9). You must work with a freight forwarder experienced in Dangerous Goods (DG) handling. Ensure all maritime declarations are accurate to avoid heavy fines or port seizures. For shipping to specific regions, confirm if the port of entry has specific quarantine or chemical import permits.

Negotiate based on volume-based pricing tiers; typically, orders exceeding 5 metric tons can secure a 5-10% discount. Discuss payment terms such as Letter of Credit (L/C) or Trade Assurance to protect your funds until the Bill of Lading (B/L) is issued. Also, request customized labeling (OEM) to ensure the instructions are in the local language of the target market for legal compliance.

Utilize the secure payment systems provided by Made-in-China.com to ensure that payment is only released upon proof of shipment. Verify the supplier's business license and export qualifications to ensure they are a legitimate manufacturer or authorized exporter, rather than an unlicensed middleman.
