Product overview

Potassium chloride — muriate of potash (MOP) — is the dominant potassium fertilizer in global trade, supplying the K that regulates stomatal function, enzyme activation and carbohydrate transport in every crop type. The 62% K2O grade is the high-analysis benchmark: it carries more potassium per tonne than the 60% standard, lowering delivered cost per kg K2O on CFR and CIF routes where ocean freight is priced by weight.

Granules sized 1–4 mm flow freely through bulk blending lines and match the particle distribution of DAP and urea in NPK compound plants across South Asia, East Africa and Latin America. Importers use MOP 62 for direct field application on chloride-tolerant cereals and oilseeds, as the potassium source in 15-15-15 and 12-12-17 compounds, and in industrial KCl applications including drilling fluids and water softening.

Supply origins include Baltic, Belarus-transit and Canadian potash complexes, with MENA consolidation for buyers routing through Gulf and Red Sea ports. Sodium chloride is held to 3.0% maximum and moisture to 0.5% maximum to limit caking during tropical warehousing and extended ocean transit.

Loading ports & logistics

MOP 62 is a non-hazardous but hygroscopic bulk commodity. Covered storage at destination and minimal dwell time in open holds reduce caking risk in humid climates.

FOB loading at Baltic terminals (Klaipėda, Ust-Luga), Canadian West Coast ports and MENA consolidation hubs with bulk-handling berths. Standard parcels range from 5,000 MT on handysize bulk carriers to 60,000 MT on panamax or capesize vessels.

CFR/CIF deliveries to South Asia (Mumbai, Chittagong, Karachi), Southeast Asia (Ho Chi Minh City, Jakarta), East Africa (Mombasa, Dar es Salaam) and Brazil. Bagged options — 50 kg PP woven bags or 1,000 kg FIBC — suit inland markets without bulk discharge infrastructure; container and break-bulk shipments from 1,000 MT.

Typical lead time 15–30 days from contract to loading window, subject to berth allocation and vessel positioning.

Packaging & documentation

Bulk shipment in vessel holds with moisture barrier tarps, or in 50 kg PP woven bags with inner PE liner and 1,000 kg FIBC big bags palletised and stretch-wrapped. Each lot ships with a mill certificate of analysis (COA), commercial invoice, packing list, bill of lading and certificate of origin. Phytosanitary certificates are issued where destination customs require them. SDS per GHS is provided on request. Third-party inspection at loading (SGS, Bureau Veritas) available for LC-backed or first-time contracts.

FAQ

Why do NPK plants prefer MOP 62 over the 60% trade grade?

The extra 2 percentage points of K2O let compounders hit higher analysis targets — such as 12-12-17 or 15-15-15 — with less filler and lower freight cost per unit of potassium on long CFR routes. Lower NaCl (3.0% max vs 3.5% in MOP 60) also reduces chloride carry-over in chloride-sensitive blends.

What bulk vessel classes carry MOP 62 from load port to destination?

Standard parcels range from 5,000 MT on handysize bulkers to 60,000 MT on panamax or capesize vessels from Baltic, Canadian and MENA load terminals. Smaller 1,000–3,000 MT coasters serve regional buyers when draft or berth constraints limit parcel size.

Which export documents accompany an MOP 62 shipment?

Each lot ships with a mill certificate of analysis, commercial invoice, packing list, bill of lading and certificate of origin. Phytosanitary certificates are issued where the destination customs regime requires them. Third-party inspection at loading (SGS, Bureau Veritas) is available for LC-backed or first-time contracts.
