MOP Potash (Muriate of Potash) 0-0-60

Potassium chloride, 60% K₂O, granular & standard

Muriate of potash is potassium chloride, about 95–98% KCl, sold on a single headline number, potassium oxide equivalent at 60% minimum (some standard grades run 61–62%), and on the grade, which describes particle size rather than chemistry. Granular MOP, screened to about 2–4 mm, is the direct-application and bulk-blending product because it spreads and blends evenly with granular urea and DAP. Standard grade is finer, below 1 mm, and goes to compound NPK manufacturers who granulate it with other nutrients, and to markets that still broadcast fine potash. Colour ranges from white to deep red depending on the iron in the ore and the process, and as with DAP it tells you nothing about K₂O. Moisture at 0.5% maximum and an anti-caking treatment matter more than most buyers expect, because MOP cakes hard in a damp hold and arrives as slabs.

Buy MOP for anything that is not chloride-sensitive: cereals, oilseeds, sugar cane, oil palm, cotton and most field crops, and for NPK manufacture where potash is the cheapest source of K. Buy SOP instead for tobacco, potatoes, fruit, vegetables and salt-affected or irrigated soils where chloride harms the crop or accumulates. The trade is dominated by Canada, Russia and Belarus, of which we work only Canadian material, together with Jordan on the Dead Sea; those origin constraints are part of the specification for this desk and are applied without discussion. CBIL brokers granular and standard MOP against independent certification of K₂O, moisture, particle size and anti-caking treatment at load, in bulk Panamax and Supramax parcels and 50 kg bags, on FOB, CFR and CIF terms.
