Humic acid
Changsha Richfield Agri Tech Co., Ltd. supplies humic acid that is an organic humic substance derived from leonardite ore, primarily potassium humate and sodium humate salts. The product is offered in powder, flake and liquid forms, each fully water‑soluble for rapid plant uptake. Its solubility in water exceeds 90 % at ambient temperature, facilitating easy integration into existing fertilizer blends. HS classification typically falls under heading 3101 for soil improvement preparations.
In the industry, humic acid commonly contains 50‑70 % humic substances with moisture levels below 10 % and ash content between 5‑10 %, values that are regarded as typical for premium grades. The material’s cation exchange capacity enhances nutrient retention, and its organic matter contributes to improved soil structure. Suppliers often test for heavy metal limits in accordance with ISO standards, a practice that aligns with the typical quality expectations for agricultural amendments.
Major buyers include fertilizer manufacturers, agribusiness distributors and large‑scale growers seeking to boost root development and water retention. The listing notes flexible minimum order quantities and shipping terms such as FOB and CIF, allowing buyers to arrange logistics according to their needs. Interested importers should confirm current MOQ, lead time and any required certification documents directly with the supplier before placing an order.

Sourcing Humic acid from Changsha Richfield Agri Tech Co., Ltd. - China Import Guide
Before placing an order, verify the source of the leonardite ore and request a recent analysis report confirming the potassium and sodium humate ratios. Confirm that the supplier can provide the ISO or SGS certificates cited in the product description, and ask for a material safety data sheet to satisfy import regulations in your destination country.
Logistics should be planned around the supplier’s offered Incoterms, typically FOB or CIF. Clarify the expected lead time, container loading port in China and any freight forwarder preferences. Payment terms are not disclosed in the listing, so negotiate clear terms such as TT or LC before finalising the contract.
Implement a pre‑shipment inspection that checks solubility, moisture content and heavy‑metal limits against the typical values stated. Arrange for a third‑party lab to verify the humic substance content of a sample batch. Retain all quality certificates and test reports for customs clearance and future quality audits.
