Muriate of Potash (MOP)

Reliable Quality & Global Supply

Muriate of Potash (MOP) 60% K₂O | Potassium Chloride

Potassium Fertilizer for Direct Application and NPK Blending

Muriate of Potash (MOP), also known as Potassium Chloride (KCl), is one of the most widely used potassium fertilizers and an important source of plant-available potassium. Fertilizer-grade MOP typically contains 60–62% K₂O and is supplied in different physical grades, including granular and crystalline forms.

At TPA | Canada, we support the sourcing and international supply of MOP according to required grade, specification, origin, packaging, quantity and delivery terms.

Product Description

MOP for Reliable Potassium Supply

Muriate of Potash provides a concentrated and water-soluble source of potassium for agricultural applications. Farmers and fertilizer producers widely use MOP for direct fertilizer application and for producing NPK and bulk fertilizer blends.

The right MOP grade depends on crop requirements, soil conditions and the required nutrient profile. Buyers can also select the appropriate particle size and physical form according to their application and handling needs.

Product Grades

Titan Prime Alliance Inc. (TPA | Canada), provides international sourcing and export solutions for MOP comes in different physical grades to support agricultural applications and fertilizer blending requirements.

A. Granular MOP

Granular MOP works well for direct field application, mechanical spreading and fertilizer blending. Its controlled particle size supports good flow and consistent spreading during large-scale agricultural operations.

B. Standard / Crystalline MOP

Standard or crystalline MOP works well for fertilizer blending and applications that require finer particle characteristics.

Commercial producers also offer MOP in different colors, including white and pink, depending on the mineral source and processing method. However, color alone does not determine the potassium content or fertilizer value of the product.

Frequently Asked Questions

Do the different colors of MOP indicate different quality or applications?

MOP is commercially available in white, pink and red-brown forms, depending mainly on the mineral source and processing method. Color alone does not determine the fertilizer value or application; however, K₂O content, chloride level, moisture, particle size and other specifications may vary between products and should be verified through the supplier's COA and Product Data Sheet.

What grades of MOP are available?

MOP is commonly available as granular, standard and crystalline grades, with white, pink or other colors depending on the product origin and processing. Grade selection depends on the intended application, blending requirements and handling conditions.

What packaging options are available for MOP?

MOP can generally be supplied in 50 kg bags, 500–1,000 kg Big Bags, or bulk, depending on the supplier, order quantity and destination requirements.

Is MOP suitable for NPK fertilizer production?

Yes. MOP is widely used as a potassium source in the production of NPK fertilizers and bulk fertilizer blends, as well as for direct agricultural application.

What information is required to request an MOP quotation?

To evaluate a supply requirement, it is helpful to provide the required grade, quantity, packaging, destination, preferred origin, delivery schedule and Incoterm. TPA | Canada can then assess suitable supply options based on the buyer's requirements.

Is MOP the same as SOP?

No. MOP (Potassium Chloride, KCl) and SOP (Potassium Sulfate, K₂SO₄) are both potassium fertilizers, but they have different chemical compositions and nutrient profiles. MOP typically provides around 60–62% K₂O and contains chloride, while SOP generally provides around 50% K₂O and also supplies sulfur. The appropriate product depends on crop requirements, soil conditions and chloride tolerance.
