Paclobutrazol 25 sc manufacturers

Buyers must ensure the active ingredient content is strictly 250g/L. Key parameters include suspension stability (≥90%), pH value (typically 5.0–8.0), and fineness (wet sieve test through 45μm mesh ≥98%). High-quality SC formulations should have excellent dispersibility and a long shelf life of at least 2 years without irreversible layering or caking.

Suppliers should provide a Certificate of Analysis (COA) for every batch. For international trade, look for manufacturers with ISO 9001 (Quality Management) and ISO 14001 (Environmental Management) certifications. Ensure the product meets FAO (Food and Agriculture Organization) specifications for pesticides and complies with the Global Harmonized System (GHS) for labeling and packaging.

It is a plant growth regulator used primarily to inhibit gibberellin biosynthesis, resulting in stunted vegetative growth, increased chlorophyll content, and enhanced root development. It is widely applied in fruit trees (like mango to induce flowering), rice (to prevent lodging), and ornamental plants to control height and improve stress resistance.

Calculate the cost per hectare rather than just the unit price per liter. Evaluate the dilution ratio; a high-quality 25% SC allows for higher efficacy at lower dosages. Consider bulk packaging (e.g., 200L drums vs. 1L bottles) to reduce unit costs by 15-20%, but factor in the specialized storage requirements for hazardous chemicals.

Paclobutrazol is often classified under UN 3082 (Environmentally Hazardous Substance, Liquid). You must ensure the supplier provides a Material Safety Data Sheet (MSDS) and a DGM report for sea or air freight. Use IMO-compliant packaging to prevent leakage, and verify that the shipping line accepts Class 9 hazardous goods to your destination port.

Utilize secured payment terms and prioritize suppliers on Made-in-China.com who have undergone Audited Supplier status by third-party agencies like SGS or Intertek. Request a pre-shipment inspection (PSI) to verify the batch number, production date, and active ingredient purity before the final balance is paid.

Check your local Ministry of Agriculture for pesticide registration requirements. Many countries require an Import Permit specifically for plant growth regulators. Ensure the labeling is in the local language and includes the registration number, toxicity category, and emergency first-aid instructions as per local law.

Negotiate based on annual volume commitments rather than one-off spot purchases to secure Tier-1 pricing. Ask for free samples (500ml-1L) for lab testing before committing to a full container. Discuss lead time guarantees, especially for seasonal agricultural products, to avoid missing the local application window.
