Potassium Sulphate
Main Hill Limited supplies potassium sulphate (K2SO4), a chloride‑free potash fertilizer sourced in Hong Kong. The product contains 50 % K2O and 17 % sulphur by weight, matching the standard nutrient analysis for sulphate of potash. It is noted for its high solubility in water, enabling rapid uptake in fertigation systems. The material is offered in bulk forms suitable for large‑scale import.
In the industry potassium sulphate is graded as agricultural or industrial, with typical purity of 99.5 % and a low salt index around 20 % of that of MOP. Common packaging includes 25 kg paper bags and 1‑tonne bulk bags, both of which can be stacked on pallets. The product conforms to typical specifications for soluble fertilizers, such as particle size below 2 mm. Suppliers often certify to ISO 9001, though Main Hill Limited does not list a specific certification in the current data.
This fertilizer is favoured by growers of fruits, vegetables and tobacco that require chloride‑free potassium. Importers usually arrange FOB or CIF terms and may request flexible minimum order quantities, which should be confirmed with Main Hill Limited. Payment is typically by T/T or L/C, subject to agreement. Buyers should verify the batch analysis report before shipment.

Sourcing Potassium Sulphate from Main Hill Limited - Hong Kong Import Guide
Before placing an order, verify that the batch analysis report confirms the 50 % K2O and 17 % sulphur figures, as well as the chloride‑free claim. Request a recent certificate of analysis and, if needed, a third‑party test report to ensure the product meets your agronomic specifications. Clarifying these details up front reduces the risk of receiving material that deviates from the expected nutrient profile.
Logistics for shipments from Hong Kong typically involve either FOB or CIF incoterms; however, exact terms should be agreed with Main Hill Limited. Confirm the expected lead time, vessel loading schedule, and any port‑handling charges. Payment methods such as telegraphic transfer or a confirmed letter of credit are common, but the precise arrangement must be negotiated and documented in the purchase contract.
Quality assurance relies on pre‑shipment inspection and verification of the supplied analysis certificate. Arrange for an independent lab to sample the cargo upon arrival, checking for purity, moisture and particle size. Ensure that the supplier provides a full set of documents, including the certificate of analysis, material safety data sheet and packing list, to facilitate customs clearance and quality control.
