HEDP
The product is 1-Hydroxyethylidene-1,1-Diphosphonic Acid, abbreviated HEDP, with molecular formula C3H9O7P2 and CAS 2809-21-4. It is supplied by Jinan Quicer Technology And Trade Co., Ltd. in China as either a colourless or light-yellow transparent liquid. The chemical functions as a scale inhibitor and corrosion inhibitor in water-treatment circuits. Supplier data lists the material in both liquid and crystalline powder forms.
HEDP chelates calcium, iron and other metal ions, reducing deposition of calcium carbonate, sulfate and iron scales. In the industry the compound is typically offered with a purity of 98% or higher and is stable across a pH range of approximately 2 to 12. Typical commercial packaging includes 25 kg steel drums for liquid and 1 tonne bulk bags for powder. The product is recognised for its ability to passivate metal surfaces over a broad temperature range.
Major users include operators of circulating cooling water systems, oil-field water-treatment plants and industrial boiler facilities. Buyers usually arrange FOB or CIF shipping terms and negotiate payment via L/C or T/T, but these must be confirmed with the supplier. The supplier does not publish a minimum order quantity, so importers should request the exact MOQ during quotation. Verification of certifications and batch test reports is advised before contract signing.

Sourcing HEDP from Jinan Quicer Technology And Trade Co., Ltd. - China Import Guide
Before placing an order, importers should request the latest certificate of analysis, safety data sheet, and any available third‑party test reports to confirm purity and compliance. Because the supplier’s response rate is not displayed, confirming the contact person and communication channel in advance is advisable. Request a sample batch if possible to verify physical appearance and solubility.
Typical logistics for Chinese chemical exporters involve freight forwarding from ports such as Qingdao or Shanghai, with lead times that can vary from two to six weeks depending on production scheduling. Buyers commonly negotiate FOB or CIF terms, and payment is usually secured through an irrevocable L/C or T/T after inspection. These conditions should be agreed in the contract and reflected in the pro‑forma invoice.
Independent pre‑shipment inspection by a recognised agency can verify packaging integrity and batch conformity. Importers may also arrange on‑site laboratory testing to assess scale‑inhibition performance against ASTM D4870. Retaining all test certificates and shipping documents will facilitate customs clearance and downstream quality assurance.
