Product overview — Potassium Nitrate Technical
Technical-grade potassium nitrate (KNO3) is a crystalline salt refined to 99.4% minimum purity with chloride and insoluble fractions an order of magnitude below agricultural grade. The 13% N and 46% K2O analysis matches standard fertigation ratios, but tighter chemical limits protect automated dosing hardware, recirculating hydroponic systems and soluble NPK production lines where sediment or chloride build-up would force costly shutdowns.
Greenhouse operators in the Gulf, Levant and North Africa specify technical KNO3 for tomato, pepper and cucumber programmes where drip emitters run 18 hours daily and any particulate matter accelerates wear. Soluble-fertilizer blenders use it as a chloride-free potassium feedstock alongside urea phosphate and calcium nitrate in water-soluble NPK formulations. Export buyers in India, Turkey and East Africa source technical grade for protected horticulture clusters serving European retail chains.
Production originates from nitric-acid neutralisation lines at Black Sea and MENA chemical complexes with dedicated crystallisation and screening stages. HS code 2834.21. MOQ from 300 MT on FOB, CFR or CIF terms.
Full product details
Loading ports & logistics — Potassium Nitrate Technical
Contract MOQ is 300 MT — fulfilled by 25 kg PE-lined bags in 20-foot containers (~20–22 MT per unit) or 1,000 kg FIBC big bags on 3,000–5,000 DWT coasters. Technical KNO3 is a hygroscopic oxidizer — dry-hold certification and segregated stowage from combustible cargo are mandatory on every consignment.
25 kg PE-lined bags palletised to 1,000 kg units suit greenhouse clusters and soluble-fertilizer blenders without bulk berth access. Container assembly from 300 MT across multiple 20-foot bookings on FOB Black Sea and MENA origins; each pallet is stretch-wrapped and desiccant-lined for humid discharge ports.
1,000 kg FIBC big bags with moisture-barrier liner move 300–3,000 MT on multipurpose or coaster vessels to protected-cultivation hubs in the Levant, Red Sea corridor and Indian west coast. Grab or crane discharge at geared terminals; covered warehouse space at destination is essential to prevent caking.
Geared bulk carriers handle annual framework contracts above 3,000 MT to dedicated nitrate berths with oxidizer-class stowage per IMDG Code. FOB loading at Novorossiysk, Taman, Jebel Ali and Damietta; CFR and CIF quotes include marine insurance and discharge-port dry-storage confirmation. Typical lead time 15–30 days from payment instrument confirmation to first laycan day.
Packaging & documentation — Potassium Nitrate Technical
Standard export packing: 25 kg PE-lined PP woven bags, palletised and stretch-wrapped; or 1,000 kg FIBC big bags with moisture-barrier liner. Each lot ships with a mill certificate of analysis confirming N, K2O, purity, chloride, insolubles and moisture. Document set includes commercial invoice, packing list, bill of lading and certificate of origin. Third-party inspection at load port (SGS, Bureau Veritas) available for LC-backed or first-time contracts. SDS per GHS supplied on request.
FAQ — Potassium Nitrate Technical
When does technical KNO3 justify the premium over agricultural grade?
Technical grade pays off where emitter clogging, chloride accumulation or batch-to-batch variability would cost more than the per-tonne uplift — automated greenhouse fertigation, hydroponic NFT channels and soluble NPK plants that recirculate nutrient solution. Agricultural grade remains adequate for broadcast and manual drip on less sensitive crops.
What purity limits protect automated dosing systems?
Water insolubles at 0.01% max and chloride at 0.01% max keep stock-tank sediment and injector wear within manufacturer tolerances. Moisture below 0.1% prevents caking in pneumatic conveying lines and preserves dissolution rate in cold irrigation water.
How is technical KNO3 stored and shipped to prevent caking?
Crystals ship in 25 kg PE-lined bags or 1,000 kg FIBC big bags with moisture-barrier liners. Bulk holds require dehumidified ventilation during ocean transit. Store under cover at relative humidity below 65%; shelf life exceeds 24 months when bags remain sealed.
