Atrazine

When sourcing Atrazine, the standard purity for Technical Grade (TC) is typically ≥97%. For formulated products, common concentrations include 50% SC (Suspension Concentrate), 80% WP (Wettable Powder), and 90% WDG (Water Dispersible Granules). Buyers must verify the moisture content (usually <0.5% for TC) and pH value (typically 5.0-8.0) to ensure chemical stability and shelf life. Always request a Certificate of Analysis (COA) for every batch to confirm these parameters.

As a restricted-use pesticide in many regions, Atrazine must comply with FAO (Food and Agriculture Organization) specifications. Suppliers should ideally hold ISO 9001 for quality management and ISO 14001 for environmental management. It is critical to ensure the product meets REACH regulations for the EU market or EPA registration requirements for the US. Furthermore, the Safety Data Sheet (SDS) must be provided in accordance with the GHS (Globally Harmonized System).

Atrazine is a selective triazine herbicide used primarily for pre-emergence and post-emergence weed control in crops like maize (corn), sorghum, and sugarcane. Its key functional advantage is its ability to inhibit photosynthesis in target weeds while remaining safe for specific crops due to their metabolic bypass. It is highly effective against broadleaf weeds and annual grasses, providing a cost-effective solution for large-scale agricultural yield protection.

Economic feasibility is driven by the active ingredient concentration per dollar. While 90% WDG may have a higher unit price, it offers lower shipping costs and easier storage compared to liquid formulations. Standard packaging for solids includes 25kg woven bags or fiber drums, while liquids are often packed in 200L HDPE drums or 1000L IBC tanks. For large-scale B2B procurement, sourcing from Made-in-China.com allows for direct factory pricing, which can reduce costs by 15-25% compared to local distributors.

Atrazine is classified under UN 3077 (Environmentally Hazardous Substance, Solid) or UN 3082 (Liquid), belonging to Hazard Class 9. It requires specialized dangerous goods (DG) packaging and declaration. Ensure the freight forwarder is experienced in handling Class 9 chemicals and that the vessel provides proper segregation from food and feedstuffs to prevent cross-contamination.

To ensure transaction security, use Trade Assurance or Letter of Credit (L/C) for large volumes. Before full payment, conduct a third-party inspection (such as SGS or Intertek) at the loading port to verify the quantity and quality. On Made-in-China.com, prioritize Audited Suppliers who have undergone comprehensive on-site verification of their manufacturing capabilities and legal status.

Focus negotiations on lead time stability and purity consistency rather than just the lowest price. Request a tiered pricing structure based on annual volume (e.g., 10MT vs 100MT). Ask for free samples (500g-1kg) for lab testing before committing to a bulk order. Additionally, negotiate payment terms that link the final 20-30% payment to the successful arrival and local testing of the goods.

Buyers must verify if Atrazine is banned or restricted in their destination country (e.g., it is banned in the EU). You must possess a Pesticide Import Permit and ensure the supplier provides a Certificate of Origin to benefit from potential Free Trade Agreements (FTAs). Failure to provide correct HS Codes (typically 3808.93) or environmental permits can lead to customs seizure or heavy fines.
