Herbicide paraquat 20 sl

Paraquat 20% SL (Soluble Liquid) is a fast-acting, non-selective contact herbicide used to control a wide range of annual grasses and broad-leaved weeds. It works by disrupting photosynthesis in green plant tissues upon contact. Key specifications include an active ingredient concentration of 200g/L, the inclusion of an emetic (vomit-inducing agent), a distinctive blue/green dye, and a strong odorant to prevent accidental ingestion. It is primarily used in non-crop areas, orchards, and for pre-plant weed control.

Paraquat is a highly regulated substance and is banned or severely restricted in many countries (including the EU, China for domestic use, and Brazil). Buyers must verify that they hold a valid Import Permit for hazardous chemicals. Suppliers must provide a Material Safety Data Sheet (MSDS), a Certificate of Analysis (COA), and ensure the product meets FAO/WHO specifications. Packaging must comply with UN-certified hazardous goods standards to prevent leakage during transit.

To ensure efficacy and safety, buyers should request third-party laboratory testing (such as SGS or BV) to confirm the active ingredient content is exactly 20%. It is critical to verify the stability of the formulation under different temperatures and the solubility in water. High-quality Paraquat should not leave significant residue in the soil as it deactivates immediately upon contact with soil particles, which is a key performance benchmark for this specific herbicide.

Due to its high toxicity, the product must be handled with Personal Protective Equipment (PPE), including chemical-resistant gloves, goggles, and respirators. It should only be applied by certified professionals. The 'SL' formulation requires clean water for dilution to avoid clogging spray nozzles. Buyers should ensure the supplier provides clear multilingual labeling that includes hazard warnings and first-aid instructions as per the GHS (Globally Harmonized System).

The biggest risk is Customs Seizure due to the product's restricted status. Many nations have moved Paraquat to 'Prohibited' lists. You must confirm the HS Code (typically 3808.93) and local legality before payment. Another risk is shipping rejection, as many carriers refuse to transport Class 6.1 Toxic Substances. Always work with freight forwarders specializing in Dangerous Goods (DG).

Use secure payment methods and prioritize suppliers on Made-in-China.com who have undergone on-site audits and 'Audited Supplier' verification. Requesting a Pre-Shipment Inspection (PSI) is vital for chemical orders to ensure the physical goods match the documentation provided for customs clearance.

Focus on packaging durability and labeling customization rather than just the lowest price. Negotiate for bulk discounts (usually applicable for 20ft container loads) but ensure the shelf life is at least 2 years. Ask the supplier if they can provide registration support documents (ICAMA or equivalent) to assist with your local import licensing.

Paraquat 20 Sl must be shipped via Sea Freight as Dangerous Goods (DG). It cannot be sent via air mail or standard courier services. Ensure the cargo is stowed away from food, feed, and living quarters on the vessel. The containers must be marked with Class 6.1 toxic placards and accompanied by a Dangerous Goods Declaration.
