Prilled urea manufacturers

When sourcing Prilled Urea, the most critical factor is the Nitrogen content, which should be a minimum of 46%. You must also verify the Biuret content; for agricultural use, it should typically be less than 1.0%, while technical grades may require even lower levels to avoid phytotoxicity. Additionally, check the moisture content (standard is <0.5%) and particle size distribution (usually 0.85mm to 2.80mm for prilled form) to ensure free-flowing characteristics and prevent caking during storage.

Buyers should mandate a Pre-shipment Inspection (PSI) conducted by reputable third-party agencies like SGS or Intertek. Request a Certificate of Analysis (COA) for every batch and ensure the supplier complies with ISO 9001 for quality management. For international trade, it is essential to confirm the product meets the national standards of the importing country (e.g., GB/T 2440 in China or specific USDA/EU fertilizer regulations).

Prilled Urea is highly hygroscopic, meaning it readily absorbs moisture from the air. It must be stored in a cool, dry, and well-ventilated warehouse. Suppliers should provide UV-stabilized woven polypropylene (PP) bags with a polyethylene (PE) inner liner to prevent moisture ingress. Ensure the pallets are not stacked too high to avoid pressure caking, which can crush the prills into powder.

The primary risks include price volatility in the global energy market and export policy shifts. Many countries, including China, may implement export inspections or quotas to prioritize domestic supply, which can lead to shipment delays. To mitigate this, use Made-in-China.com's secured payment services and ensure your contract includes a Force Majeure clause specifically addressing government-mandated export restrictions.

For large volumes, the industry standard is an Irrevocable Letter of Credit (L/C) at sight or Telegraphic Transfer (T/T) with a deposit and balance against BL. When negotiating, clarify the Incoterms; FOB (Free On Board) is often preferred by experienced buyers to maintain control over freight costs, but CIF (Cost, Insurance, and Freight) may be easier for new buyers. Always verify the loading rate at the port to avoid demurrage charges.

Required documents typically include the Commercial Invoice, Packing List, Bill of Lading, Certificate of Origin, and the Phytosanitary Certificate (if required by the destination country). Because Urea can be a precursor for explosives, some regions require an End-Use Certificate (EUC). Ensure the supplier on Made-in-China.com is an Audited Supplier to guarantee they have the legal capacity to export chemical products.
