We supply potassium chloride (MOP / muriate of potash) for fertilizer blending, industrial processing, water softening, oil drilling and food applications. Available in granular, powder and crystal forms with 25kg bags, jumbo bags, COA, TDS and MSDS for global B2B buyers.
Potassium Chloride (MOP) Specifications
Potassium chloride, also called muriate of potash (MOP), is the most widely used potassium fertilizer worldwide. It delivers ~60% K2O — the highest potassium concentration among common fertilizers — making it the economical choice for large-scale agriculture, industrial processing, and various chemical manufacturing applications.

MOP vs SOP: Quick Comparison
| Property | MOP (Potassium Chloride) | SOP (Potassium Sulfate) |
|---|---|---|
| K2O Content | ~60-62% | ~50% |
| Chloride | ~47% | <1% |
| Sulfur | None | ~18% S |
| Best For | General field crops, pasture, chloride-tolerant crops, industrial use | Chloride-sensitive crops, fruits, vegetables, tobacco, tea |
| Price Position | Economy — lowest cost per unit K2O | Premium — for quality-focused crop programs |
MOP is the world's most widely traded potassium fertilizer because it delivers the most potassium per dollar. SOP is only needed when chloride sensitivity or crop quality requirements justify the premium.

This checklist helps procurement teams compare real bulk supply, not casual retail purchases.
FAQ About Potassium Chloride (MOP)
What is potassium chloride (MOP) used for?
Potassium chloride is the most widely used potassium fertilizer globally (60-62% K2O). It is also used in industrial water softening, oil drilling fluids, food processing as a salt substitute, and various chemical manufacturing processes.
What is the difference between MOP and SOP?
MOP (muriate of potash) contains ~60% K2O with ~47% chloride. SOP (sulfate of potash) contains ~50% K2O with less than 1% chloride plus ~18% sulfur. MOP is the economical choice for chloride-tolerant crops; SOP is preferred for chloride-sensitive, high-value crops.
What grades of potassium chloride do you supply?
We supply fertilizer grade (60-62% K2O), industrial grade, and food grade potassium chloride. Forms include granular, powder, and crystal. Please specify your target application and grade requirement.
What packaging options are available?
Standard packaging includes 25kg bags, 50kg bags, and 1000kg jumbo bags. Pallet packing and OEM labels can be discussed by order. Export-quality woven bags protect product integrity during long-distance shipping.
Can you provide COA, TDS and MSDS?
Yes. COA showing K2O content, moisture, and impurity levels; TDS for technical specifications; and MSDS for safe handling. All available for buyer review before order confirmation.
What is the MOQ for bulk potassium chloride orders?
MOQ depends on grade and packaging format. Trial orders are often supported. Full container loads (approximately 25-27MT per 20-foot container) offer the most economical freight cost per ton.

Buyer Notes for Potassium Chloride Orders
Choose the grade basis
Potassium chloride buyers may need granular, powder, tablet or other forms. Confirm KCl content, K2O equivalent when relevant, particle size and anti-caking requirement before comparing suppliers.
Check handling quality
Dust, caking, moisture and broken granules can affect blending and warehouse work. Ask for recent photos or sample review when the product will be repacked or used in fertilizer blending.
Align shipment terms
Regular KCl programs should define packing, pallet, destination port, documents and delivery window in writing. This makes repeat quotations easier and reduces changes after the order is placed.
