Mesotrione

When sourcing Mesotrione, the Technical Grade (TC) typically requires a purity of ≥95% or ≥98%. For formulated products, common concentrations include 480g/L SC (Suspension Concentrate) or 10% SC. You must verify the CAS No. 104206-82-8 and request a Certificate of Analysis (COA) to check for impurity levels, as high-quality Mesotrione should have a stable pH range (usually 3.0 - 7.0) and excellent dispersion stability in liquid forms.

Mesotrione is a selective pre-emergence and post-emergence herbicide primarily used for maize (corn), sugar cane, and flax. It functions by inhibiting the HPPD enzyme, leading to chlorophyll destruction (bleaching). B2B buyers should ensure the product is marketed for its broad-spectrum control against annual broadleaf weeds and some grassy weeds, offering long-lasting residual activity and high safety margins for corn crops.

Suppliers must provide a Material Safety Data Sheet (MSDS) and comply with FAO (Food and Agriculture Organization) standards. For entry into specific markets, ensure the manufacturer has EPA registration (USA) or EU pesticide database approval. Additionally, because it is a chemical substance, the packaging must adhere to UN-certified hazardous goods standards to prevent leakage during maritime transport.

Evaluate the production capacity (e.g., annual output >1000 tons) to ensure supply stability during peak farming seasons. Look for manufacturers on Made-in-China.com that hold ISO 9001 (Quality Management) and ISO 14001 (Environmental Management) certifications. Comparing the price per active ingredient percentage is more effective than comparing unit prices alone, as concentrated formulations can significantly reduce international freight costs.

The biggest risks include regulatory seizure due to lack of registration and quality degradation during transit. To mitigate these, use Trade Assurance services on Made-in-China.com to secure payments. Always conduct a pre-shipment inspection (PSI) via third parties like SGS to verify the active ingredient content and packaging integrity before the balance payment is released.

Mesotrione is often classified under HS Code 380893 (Herbicides). Since it may be classified as a Class 9 Miscellaneous Dangerous Good depending on the formulation and concentration, you must ensure the supplier provides a Dangerous Goods Declaration and uses IMDG-compliant shipping lines. For liquid SC formulations, temperature-controlled containers or specialized IBC tanks may be required to prevent phase separation during long-haul sea freight.

Focus on Volume-Based Pricing; discounts of 5-10% are common for full container loads (FCL). Negotiate for customized packaging/labeling (OEM) which is vital for local market compliance. Request a 2-year shelf-life guarantee and clarify the lead time, as agrochemicals are highly seasonal; top-tier suppliers should offer a 20-30 day lead time for standard formulations.

Never transfer funds to private bank accounts; always use corporate accounts verified by Made-in-China.com. For first-time orders, utilize a Letter of Credit (L/C) or a staged payment plan (30% deposit, 70% against B/L copy). Ensure the contract specifies the analytical method (e.g., HPLC) to be used in case of a quality dispute to avoid ambiguity during arbitration.
