EDTMPA (Ethylenediamine tetra‑methylene phosphonic acid) is a nitrogenous organic polyphosphonic acid used as a corrosion inhibitor. It creates a protective film on metal surfaces, reducing corrosion rates in power generation and refining environments. The compound remains stable at temperatures up to 250 °C, making it suitable for high‑heat processes. It is biodegradable, aligning with environmental regulations.
The product is supplied as a white crystalline powder with a molecular weight of 358.1 g mol⁻¹ and the formula C₂H₈N₂O₁₀P₄. Purity is typically ≥98 % assay, and a 10 % aqueous solution has a pH between 2.0 and 3.0. Typical corrosion inhibition efficiency exceeds 95 % on carbon steel in aggressive media. These characteristics match standard specifications for industrial‑grade phosphonic acid inhibitors.
Major users include thermal power plants, oil refineries and large‑scale cooling systems that require long‑term metal protection. Buyers generally request flexible MOQ and may negotiate payment by L/C or T/T, with shipping terms such as FOB or CIF. Hebei Tianao Technology Co., Ltd states that certifications such as ISO and SGS are available on request, and customized packaging can be arranged for bulk transport.

Before placing an order, verify that the supplier can provide a current Certificate of Analysis, material safety data sheet and any environmental compliance documents required for your market. Request a sample where feasible to confirm purity, physical form and solubility. Clarify whether the product meets any specific regulatory standards that apply to your downstream application.
Discuss logistics early - ask the supplier which Incoterms they can support (FOB, CIF, etc.) and the expected lead time from order confirmation to shipment. Payment methods such as irrevocable L/C or T/T should be negotiated, and any advance payment requirements clarified. Ensure that the shipping container type and volume match the supplied packaging to avoid handling issues.
Arrange for third‑party inspection either pre‑shipment or at the destination to verify that the chemical matches the agreed specifications. Common checks include assay, moisture content and verification of biodegradability claims. Retain all inspection reports and certificates as part of the import documentation for customs clearance.
