Potassium Nitrate (KNO₃) Description
Raison Chemical——Potassium Nitrate (KNO₃), commonly referred to as Nitrate of Potash (NOP), is a fully water-soluble, chloride-free NK source (approx. 13–14% N as 100% nitrate-N / 46% K₂O). Because nitrogen is supplied in nitrate form, it is immediately available for plant uptake without relying on soil microbial conversion, making it especially suitable for high-value crops, fertigation/hydroponics, and periods of active fruiting / stress recovery.

Key Benefits of Potassium Nitrate / Nitrate of Potash (NOP)
- Immediate Nutrient Availability
Supplies 100% nitrate-nitrogen (NO₃⁻) for instant plant uptake without soil conversion, eliminating ammonia toxicity risks and delivering rapid response during critical growth stages. - Chloride-Free Premium Formula
Zero chloride content prevents leaf burn and salt stress, making it ideal for chloride-sensitive high-value crops including tobacco, potatoes, grapes, strawberries, and citrus. - Optimized N:K Ratio (1:3.4)
Perfect 13.5% N + 46% K₂O balance promotes fruit development, sugar accumulation, color enhancement, and improved shelf life without excessive vegetative growth. - Superior Fertigation Performance
Exceptional solubility (>316g/L at 20°C) ensures complete dissolution with zero residues, preventing emitter clogging in drip irrigation systems and hydroponic setups. - Enhanced Stress Resistance
Strengthens cell walls and osmotic regulation, improving crop resilience against drought, extreme temperatures, and disease pressure while boosting overall plant vigor. - Export-Compliant Quality Assurance
Consistent crystalline structure with low impurities meets international fertilizer standards, supported by full documentation (COA, MSDS, SGS) for seamless global shipping.

Physical Properties
| Property | Typical Value | Notes |
|---|---|---|
| Melting Point | 334 °C | Decomposes upon further heating |

| Solubility in Water | Highly soluble | Increases significantly with temperature (e.g., 31.6g/100g water at 20°C) |
| Solubility in Alcohol | Insoluble | Does not dissolve in anhydrous ethanol or ether |
| Hygroscopicity | Very low | Excellent anti-caking properties, remains free-flowing |
Chemical Properties
- Oxidizing Agent: Potassium Nitrate is a strong oxidizer. It readily releases oxygen when heated, which supports the combustion of other materials.
- Thermal Decomposition: When heated above 334°C, it decomposes to produce potassium nitrite and oxygen gas. Further heating leads to the formation of potassium oxide and nitrogen oxides.
- Reaction: 2KNO3 → 2KNO2 + O2↑
- Stability: It is stable at room temperature but should be kept away from heat sources, open flames, and reducing agents.
- Compatibility: Reacts violently with combustible materials (such as sulfur, carbon, and organic matter), strong acids, and active metals, posing a significant fire or explosion hazard.

1) What products does Raison Chemical mainly supply?
A: We focus on two core categories:
Agricultural fertilizers: Urea (46% N, prilled/granular), NPK compound fertilizers, Potassium Nitrate (technical/agri grade) and related potash/blended fertilizers.
Industrial & hazardous chemicals: organic peroxides/initiators (MEKP, BPO, etc.), corrosive chemicals (e.g. Caustic Soda flakes/liquid, acids), and associated inorganic salts/industrial materials.
We position ourselves as an integrated supplier covering sourcing, quality check, repacking/labeling, warehousing coordination and export documentation.
2) Are your chemicals “genuinely compliant” for export? What documents do you provide?
Q: How do you guarantee compliance and smooth customs clearance?
A: Compliance is non-negotiable in our segment. For each shipment we can prepare the standard export document set required by most importers:
COA / MSDS(SDS) per batch
Certificate of Origin
Commercial Invoice / Packing List
When needed: SGS/third-party inspection, quantity & quality reports, and additional certificates (depending on destination & product)
For hazardous goods (DG), we work within the required DG framework: proper UN marking, DG declarations, and DG-class aware logistics booking from Qingdao/Shanghai/Tianjin.
3) Potassium Nitrate is a controlled / hazardous product—can you legally supply and export it?
A: Yes—KNO₃ is part of our handled range, but we treat it as what it is: a 5.1 oxidizer and a controlled/regulated item in many jurisdictions. We only offer it when the inquiry matches a lawful end-use and the buyer can work with proper DG procedures (correct documentation, compliant packaging, and DG-capable carriers). If you are unsure about your local import permit/license path, tell us your country & HS code requirement and we’ll align the paperwork accordingly.
4) Do you support custom packaging / OEM private labeling?
A: Yes. Common options include 25 kg / 50 kg PP woven + PE inner, and FIBC/Jumbo bags (500/1000 kg). We can arrange OEM bag printing (your logo, multi-language labels, lot/batch info). For hazardous items, any “custom pack” must still respect DG/UN packaging rules—so we’ll confirm which artwork/labels are feasible before production.
5) What are your typical lead times and shipping ports?
A: After deposit & artwork confirmation (if any), typical windows are roughly:
In-stock / spot arrangements: 7–15 days to readiness
Made-to-order / special specs / OEM bags: 15–30 days (depends on spec, inspection, DG queue)
Main export gateways: Qingdao / Shanghai / Tianjin, chosen by cargo type, container equipment and routing cost.
6)What is your MOQ and payment terms?
A: For most lines we quote against 1×20ft FCL as the practical MOQ (to keep unit cost & logistics sane). Smaller LCL lots are possible case-by-case—especially for DG where carriers/permits drive feasibility.
Payment norm: T/T (30% deposit + 70% against copy docs / BL); other terms discussed per client profile & inspected track record.
7) Can I get samples before placing a full container order?
A: Yes. We can arrange small representative samples (often courier / local express) for your lab check. For hazardous items, sample channel must follow DG courier rules—sometimes that means higher cost or an alternative arrangement. Sample cost & freight are usually on buyer’s account; refundable against first container in many cases.
