NPK 15-15-15 Fertilizer

NPK 15-15-15 is a balanced compound fertilizer containing 15% nitrogen, 15% phosphorus (P2O5), and 15% potassium (K2O). It provides equal proportions of the three primary macronutrients, totaling 45% active nutrients, making it ideal for general-purpose crop nutrition and baseline soil fertility programs.

NPK 15-15-15 is suitable for maize, rice, soybean, groundnut, vegetables (tomatoes, peppers, cabbage), fruit trees, sugarcane, coffee, tea, and oil palm. Its balanced formula makes it versatile for virtually all crops requiring baseline NPK nutrition.

Our NPK 15-15-15 guarantees: Total Nitrogen (N) 15.0% minimum, Available Phosphorus (P2O5) 15.0% minimum, Water-Soluble Potassium (K2O) 15.0% minimum. Moisture 2.0% maximum. Granule size 2-4mm (90% minimum). Every batch includes a Certificate of Analysis.

NPK 20-20-20 contains 33% more nutrients per bag (60% total vs 45%). This means less product is needed per hectare for the same nutrient dose. NPK 15-15-15 is preferred for general-purpose farming and sandy soils where split applications are needed. NPK 20-20-20 is preferred for high-value crops, intensive farming, and distant markets where shipping cost per nutrient matters.

Apply as basal dressing during land preparation or at planting time. Broadcast and incorporate into soil 5-7cm deep, or band-place alongside the seed row. For top dressing, apply during early vegetative growth stages. Typical rates range from 150-400 kg/ha depending on crop, soil fertility, and target yield.

Yes. Thai Fertilizer exports NPK 15-15-15 in 50kg PP woven bags with PE liner, 25kg retail bags with custom printing, and 1000kg FIBC jumbo bags. We offer competitive FOB Bangkok and CIF pricing to your destination port, with third-party inspection through SGS, Bureau Veritas, or FIGICO Intl.

Standard MOQ is one 20-foot container (approximately 25-27 MT, or 500-540 bags of 50kg each). Trial orders of 10 MT can be arranged. Bulk orders of 100+ MT receive volume discounts. Container loading takes 2-3 hours with experienced teams.

Production lead time is 10-15 days from order confirmation. Ocean freight from Laem Chabang Port, Thailand takes 15-35 days depending on destination: East Africa 18-25 days, West Africa 25-35 days, South Asia 10-18 days, Southeast Asia 7-14 days.

Every shipment includes: Certificate of Analysis (COA), Certificate of Origin (Thai Chamber of Commerce), Commercial Invoice, Packing List, Bill of Lading (B/L), Phytosanitary Certificate (where required), Material Safety Data Sheet (MSDS), and Fumigation Certificate if wooden pallets are used.

Yes, custom brand printing with your logo, product name, NPK analysis, and local language information is available for orders over 100 metric tons. Custom printing requires 2-3 weeks additional lead time for bag plate preparation.

When stored properly on pallets in a dry, covered warehouse, NPK 15-15-15 maintains quality for 12-24 months. The anti-caking coating applied during production provides 6-12 months of protection. Avoid exposure to moisture and high humidity.

We accept: Irrevocable Letter of Credit (L/C) at sight for large orders, Telegraphic Transfer (T/T) with 30% deposit and balance against shipping documents, and bank transfer for smaller orders. Payment terms may vary based on order size and buyer history.

NPK 15-15-15 is primarily designed for soil application. While it can be dissolved for fertigation, the filler content may clog emitters. For drip irrigation systems, we recommend fully water-soluble NPK formulations. Contact us for water-soluble NPK options.

The Harmonized System Code for NPK compound fertilizers like 15-15-15 is typically 3105.20 (fertilizers containing nitrogen, phosphorus, and potassium). We include the correct HS Code on all commercial invoices and shipping documentation.

Yes, we produce custom NPK blends based on your soil analysis and crop requirements. Custom formulations require a minimum order of 50 MT and 2-3 weeks additional lead time. Contact our agronomy team for formulation recommendations based on your market.

Yes, NPK 15-15-15 can be supplemented with Urea 46-0-0 during vegetative growth stages to boost nitrogen supply. Apply NPK at planting for baseline nutrition and top-dress with urea during active growth for maximum leaf and stem development.

NPK 15-15-15 delivers all three macronutrients in one application, saving labor and ensuring even distribution. Single-nutrient fertilizers like Urea, DAP, and MOP allow more precise control over each nutrient but require multiple applications. Many successful programs use NPK 15-15-15 as basal fertilizer and supplement with Urea or MOP as top dressing.

We export NPK 15-15-15 to over 40 countries including Nigeria, Kenya, Ghana, South Africa, India, Vietnam, Indonesia, Philippines, Brazil, Peru, and throughout the Middle East and Southeast Asia. We provide full documentation for each destination country's import requirements.
