Npk 17-17-17 price manufacturers

NPK 17-17-17 is a balanced compound fertilizer containing 17% Nitrogen (N), 17% Phosphorus (P2O5), and 17% Potassium (K2O). Buyers must confirm the source of Nitrogen (Ammonium vs. Nitrate), the water solubility percentage (especially for fertigation), and the granule size uniformity (typically 2-4mm). Ensure the moisture content is below 1% to prevent caking during long-term storage and sea transit.

Suppliers should provide a Certificate of Analysis (COA) for every batch. For international trade, look for compliance with ISO 9001 for quality management and ISO 14001 for environmental standards. Depending on the destination, you may require a Pre-Shipment Inspection (PSI) report from agencies like SGS or Intertek to verify that the nutrient content matches the 17-17-17 label claim.

There are two main types: High-tower granulation and Rotary drum granulation. High-tower products usually have higher water solubility, smoother appearance, and faster release, making them more expensive. Rotary drum products are often more cost-effective for broad-acre farming. Buyers should choose based on the application method—drip irrigation requires high-tower or water-soluble grades, while manual spreading can utilize drum-granulated types.

NPK 17-17-17 is hygroscopic, meaning it absorbs moisture from the air. It must be stored in a cool, dry, and well-ventilated warehouse. For usage, it is a universal fertilizer suitable for a wide range of crops including cereals, fruits, and vegetables, providing balanced nutrition during the vegetative growth and flowering stages.

The biggest risks are nutrient deficiency (adulteration) and weight shortages. Always use Trade Assurance and mandate a third-party laboratory test before the final payment is released. Additionally, be aware of fluctuating raw material costs (Ammonia, Phosphate rock, Potash) which can affect the validity of price quotes; usually, quotes are only valid for 3-7 days.

Focus on Volume-Based Pricing. For NPK 17-17-17, the price per ton drops significantly when ordering in full container loads (FCL), typically 25-27 tons. Ask for OEM packaging discounts if you provide the bag design, and negotiate payment terms such as 30% deposit and 70% against the Bill of Lading (B/L) to balance cash flow and security.

Fertilizers are sensitive to humidity. Ensure the supplier uses PP/PE woven bags with an inner plastic liner (typically 25kg or 50kg bags). Request container desiccant bags and ensure the container is watertight and clean to avoid contamination. For large orders, consider Jumbo Bags (1000kg) to reduce handling costs at the destination port.

Verify the supplier's Export License for Fertilizers, as some countries have strict quotas or inspection requirements (like China's CIQ). Use Made-in-China.com's audited supplier reports to check the factory's actual production capacity. Ensure all documents, including the Commercial Invoice, Packing List, and Phytosanitary Certificate (if required), strictly match the Harmonized System (HS) code 310520.
