Potassium humate
Zhejiang Topc Chemical Industry Co., Ltd, based in Hangzhou, Zhejiang, China, offers potassium humate derived from high‑grade Leonardite and lignite. The product appears as black flakes or powder and contains a humic acid content ranging from 60 % to 80 % as indicated by the supplier’s description. It is fully water‑soluble, allowing easy incorporation into liquid fertiliser blends, and is normally shipped in 25 kg bags or jumbo bags for bulk distribution.
Typical industry practice grades potassium humate as an agricultural‑grade amendment, with mesh sizes commonly supplied at 40 mesh and 80 mesh for different application rates. The material exhibits a pH of about 8‑9 and a moisture content below 10 % when stored properly, which matches standard specifications for soil conditioners. Standard packaging includes sealed 25 kg polypropylene bags, while larger orders may use jumbo bags of up to 500 kg, both designed to protect the product from moisture ingress.
Farmers, horticultural producers and landscape contractors use potassium humate to improve soil structure, increase water retention and enhance nutrient uptake. Bulk procurement is typical, with trade terms such as FOB or CIF negotiated per shipment. Because the listing does not disclose a minimum order quantity, lead time or exact pricing, purchasers should confirm these details directly with Zhejiang Topc Chemical Industry Co., Ltd. Requesting a recent analysis report and confirming the product’s mesh size will ensure suitability for your agronomic program.

Sourcing Potassium humate from Zhejiang Topc Chemical Industry Co., Ltd - China Import Guide
Prior to ordering, confirm Zhejiang Topc Chemical Industry Co., Ltd’s corporate registration, address and harbour‑tier verification status. Request the most recent analysis certificate, material safety data sheet and any applicable phytosanitary certificates to ensure the product meets your regulatory requirements. Verifying the mesh size and moisture content will help avoid inconsistencies in field performance.
Shipping of potassium humate is usually arranged under FOB or CIF terms, with bulk bags loaded into containers for sea freight. Confirm the preferred Incoterm, expected vessel departure schedule and any port‑specific documentation required for customs clearance in your destination country. Payment arrangements are typically negotiated per transaction; common methods include a letter of credit or T/T after inspection, but exact terms should be agreed directly with the supplier.
Quality control often involves third‑party testing of humic acid content, pH and moisture levels before shipment. Arrange an independent laboratory analysis of a pre‑shipment sample to validate the 60‑80 % humic acid claim. Ensure that the supplier can provide a certificate of analysis and that any required export licences are secured before the cargo is dispatched.
