I have found results from400+products and200+suppliers aboutMuriate of potash































Buyers must prioritize the Potassium Oxide (K2O) content, which should typically be 60% or 62% for high-grade agricultural use. Additionally, check the moisture content (usually <1%) and particle size distribution (Granular vs. Standard/Powder). For fertigation, ensure the product is 100% water-soluble to prevent clogging irrigation systems.
Ensure the supplier complies with ISO 9001 for quality management. For specific markets, look for SGS or Intertek pre-shipment inspection reports to verify purity and chemical composition. If used in organic-adjacent farming, check for OMRI listing or local agricultural department registrations.
Granular MOP is preferred for mechanical bulk blending and direct soil application due to its uniform spread and lower dust levels, often commanding a price premium. Standard or Fine MOP is more economical and suitable for manual application or as a raw material for NPK compound fertilizer production.
MOP is hygroscopic, meaning it absorbs moisture from the air. It must be stored in a cool, dry, and well-ventilated warehouse. For cross-border shipping, ensure the use of moisture-proof PP/PE woven bags (25kg, 50kg, or 1000kg jumbo bags) with inner liners to prevent caking during sea transit.
The most significant risks include price volatility in the global potash market and purity fraud. To mitigate this, use Letter of Credit (L/C) as a payment method and mandate a third-party chemical analysis at the loading port. Always source from verified manufacturers on Made-in-China.com to ensure supplier legitimacy.
Fertilizers are often subject to export taxes or quotas (especially from major producers like China). Verify the current HS Code (3104.20.00) regulations in both the exporting and importing countries. Ensure the supplier provides a Certificate of Analysis (COA) and a Material Safety Data Sheet (MSDS) for smooth customs clearance.
For orders exceeding 500 tons, Bulk Vessel shipping is most economical. For smaller B2B orders (20-200 tons), 20ft containers (FCL) are standard. Negotiate FOB (Free On Board) terms if you have a reliable freight forwarder, or CIF (Cost, Insurance, and Freight) if you prefer the supplier to handle the complex maritime logistics.
Utilize the Secured Trading services provided by Made-in-China.com to protect your funds. Conduct a factory audit (either virtual or via a third-party agency) to confirm the supplier's annual production capacity and stock levels before transferring large deposits.
