Reliable Global Supply of Potassium Nitrate 13-0-46 (NOP)

We supply Potassium Nitrate (NOP) 13-0-46 to importers, distributors, fertigation equipment suppliers, and high-value crop producers worldwide. As a fully water-soluble, chloride-free source of both nitrate-nitrogen and potassium, NOP is the preferred late-season and fruit-development fertilizer in intensive vegetable, fruit, and greenhouse production. Available from approved producers in Israel, Chile, Europe, and China, subject to grade and origin availability.

We supply business buyers only — no retail sales. Orders ship as LCL or FCL.

Read the full Potassium Nitrate 13-0-46 (NOP) product overview

Potassium Nitrate (KNO₃, NOP) contains 13% nitrate-nitrogen and 46% K₂O, providing simultaneous potassium and nitrate nutrition in a single, fully soluble product. Its chloride-free formulation is critical for crops where chloride accumulation impairs quality — including potato, tobacco, citrus, strawberry, tomato, pepper, and cucumber. NOP also has an alkalising effect compared to ammonium-based fertilizers, helping to buffer solution pH in drip fertigation systems.

The nitrate-N form in NOP is immediately plant-available, supporting rapid potassium and nitrogen uptake during critical growth and fruit-fill stages. In fertigation programs, NOP is commonly applied during reproductive and fruit-development phases when K demand peaks and excess N is undesirable. In foliar programs, NOP at 1–3% solution concentration is used to boost fruit size, skin finish, and post-harvest quality in tree fruit and vine crops.

We source potassium nitrate from verified producers in Israel (a world-scale NOP producer), Chile, European specialty fertilizer plants, and Chinese manufacturers. Low-chloride and technical-grade specifications are confirmed from producer COAs. Full export documentation — including COA, Certificate of Origin, and MSDS — is provided with every shipment.

Frequently Asked Questions

What is the MOQ for Potassium Nitrate?

Smaller quantities can ship LCL (part-container load) or as full 20ft containers (FCL) of roughly 20–25 MT. Smaller pallet quantities may be available from certain distributors for initial trials. Factory-direct supply from Israel or Chile typically requires 1–5 container minimum. Please share your target volume and destination so we can confirm the most suitable supply route.

What packaging is available for Potassium Nitrate?

Standard export packaging is 25 kg PP/BOPP bags on pallets and 1 MT jumbo/FIBC big bags. Containerised shipment in 20ft or 40ft containers is the typical export mode. Private-label bags are available subject to MOQ and origin confirmation.

Which origins do you source Potassium Nitrate from?

Our potassium nitrate supply network includes Israel, Chile, Europe, and China. Israeli and Chilean NOP are considered benchmark grades in international trade. Chinese NOP is cost-competitive and widely accepted in many markets. Origin selection depends on price, specification, lead time, and destination compliance requirements.

Is Potassium Nitrate classified as a dangerous good?

Yes. Potassium nitrate is an inorganic oxidiser classified as IMDG Class 5.1 (UN 1486). This requires an MSDS, dangerous goods declaration, and compliance with applicable packaging regulations. We ensure all required dangerous goods documentation is prepared for each shipment. Destination import permits for oxidising materials may also be required — buyers should confirm with their import authority.

Can independent inspection be arranged?

Yes. SGS or Intertek pre-shipment inspection, including quantity survey and independent sampling, can be arranged at load port upon buyer request. Inspection scope and costs are agreed in the contract.

What Incoterms are available for Potassium Nitrate?

We offer FOB, CFR, and CIF terms. Given the dangerous goods classification, insurance and freight arrangements must account for oxidiser handling requirements. We will confirm available Incoterms and any origin-specific shipping restrictions when responding to your enquiry.

Product availability, pricing, origin, documentation, and shipment terms are subject to supplier confirmation, destination regulations, sanctions screening, and contract agreement.
