Fentin acetate manufacturers

Fentin Acetate (CAS No. 900-95-8) is a potent organotin fungicide and algicide. For B2B procurement, the Technical Grade (TC) should typically have a purity of ≥95%. It is essential to verify the melting point (118-122°C) and moisture content (≤0.5%) to ensure chemical stability. For formulated products like Wettable Powder (WP) or Suspension Concentrate (SC), ensure the particle size distribution allows for optimal dispersion and suspension stability in water.

Fentin Acetate is primarily used as a protective fungicide with some repellent action against larvae. It is highly effective in sugar beet for Cercospora leaf spot, potatoes for late blight, and paddy rice for controlling aquatic snails (Pomacea canaliculata). It is also used in industrial anti-fouling paints. Buyers must ensure the application dosage is strictly controlled to avoid phytotoxicity, as some plant varieties are sensitive to organotin compounds.

As a hazardous chemical, Fentin Acetate is subject to strict international regulations. It is often classified under UN Number 2786 (Organotin pesticide, solid, toxic). Suppliers must provide a Material Safety Data Sheet (MSDS/SDS) compliant with GHS standards. Buyers must check if the product is registered under REACH (EU) or EPA (US) and ensure it meets the FAO/WHO specifications for pesticides. Many countries have restricted its use due to environmental persistence, so verifying local import permits is mandatory.

Prioritize suppliers who provide a Certificate of Analysis (COA) for every batch. Request HPLC (High-Performance Liquid Chromatography) test reports to confirm the active ingredient content. For long-distance cross-border shipping, ask for accelerated storage stability tests (usually 14 days at 54°C) to ensure the product does not degrade or cake during transit. Third-party inspections by agencies like SGS or BV are highly recommended before final payment.

The main risks include regulatory seizure due to improper labeling and chemical degradation caused by poor packaging. Because it is a Class 6.1 Toxic Substance, any discrepancy in the Dangerous Goods (DG) declaration can lead to heavy fines or port rejection. Always use Made-in-China.com's audited suppliers to mitigate the risk of receiving sub-standard or adulterated chemicals.

Fentin Acetate must be packed in UN-approved packaging, typically 25kg fiber drums with inner plastic liners or specialized bags for WP formulations. The outer packaging must display permanent hazard labels and UN markings. For shipping, Sea Freight (FCL) is the standard; ensure the carrier is authorized to handle IMO Class 6.1 goods and that the container is placed in a cool, well-ventilated area away from food and feedstuffs.

When negotiating, focus on volume-based pricing (discounts of 5-10% for 5+ ton orders) and payment milestones. Use Letter of Credit (L/C) or Trade Assurance services on Made-in-China.com to ensure funds are only released upon verification of shipping documents and quality certificates. Clearly define the Incoterms (e.g., CIF or CFR) to establish who is responsible for the complex DG logistics and insurance.
