Product overview
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.

Loading ports & logistics
FOB — bagged or big-bag loading at Black Sea chemical terminals (Novorossiysk, Taman) and MENA ports (Jebel Ali, Damietta, Dammam). Technical KNO₃ moves primarily in 25 kg PE-lined bags palletised to 1,000 kg units or in 1,000 kg FIBC big bags. Parcel sizes from 300 MT on 3,000–5,000 DWT coasters up to 3,000 MT on multipurpose vessels.
CFR / CIF — ocean freight and marine insurance added to the FOB price. Common discharge corridors include East Mediterranean greenhouse hubs, Red Sea import terminals and Indian west-coast ports serving protected-cultivation clusters. Contract lead time 15–30 days from payment instrument confirmation to first laycan day.
Containerised shipments of 20–22 MT net per 20 ft unit available for buyers without bulk berth access. Technical grade must remain dry during transit — moisture ingress above 0.3% accelerates caking and slows dissolution in cold stock tanks.
Packaging & documentation
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
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.
