HEDP Na4
HEDP Na4 supplied by Twin International Co., Ltd. is presented as a white powder that can be dissolved to form a colourless to light-yellow transparent liquid. The specification lists an active HEDP component of 20.3% - 21.7% by weight and an HEDPNa4 component of 29.0% - 31.0% by weight, while total phosphoric acid (as PO4³-) is 52.0% - 54.0%. Additional parameters include a maximum iron impurity of 20 ppm and a dry-weight loss not exceeding 15%. The product density at 20C is reported between 1.26 g/cm3 and 1.36 g/cm3.
In the chemicals market, HEDPNa4 is classified as a tetra-sodium phosphonate used as a scale and corrosion inhibitor for low-pressure boiler water, circulating cooling systems and swimming-pool water. Typical commercial grades contain around 55% phosphoric-acid equivalent and exhibit a pH of 10-12 when prepared as a 1% aqueous solution, matching the supplier’s listed values. The compound’s weak acidity and high chelating capacity make it suitable for protecting metal surfaces in oil-field pipelines and municipal water treatment plants. Standard practice also calls for storage in polyethylene liners within woven bags to preserve stability.
Industrial buyers such as power-plant operators, oil-field service companies and municipal water authorities source this chemical to reduce scale formation and prolong equipment life. The supplier indicates flexible packaging options, including 250 kg drums for the liquid form and polyethylene-lined bags for the solid powder, allowing adaptation to different handling capacities. Shipping can be arranged under FOB or CIF conditions, but exact lead times and payment terms are not disclosed and should be verified directly with Twin International. Prospective purchasers are encouraged to request safety data sheets and any applicable test certificates before finalising the order.

Sourcing HEDP Na4 from Twin International Co., Ltd. - China Import Guide
Before committing to a purchase, importers should request the latest certificate of analysis and safety data sheet to verify the active HEDP and HEDPNa4 percentages and to confirm the product’s colour and physical form. It is also prudent to review Twin International’s harbor trust-tier status and ask for references to recent export shipments. Confirm that the chosen packaging (250 kg drums or polyethylene-lined bags) matches your facility’s handling capabilities.
Logistics arrangements should be clarified early; the supplier offers both FOB and CIF terms, so buyers need to decide which party will assume freight and insurance responsibilities. Although lead time is not specified in the source, ask the supplier for an estimated production and shipping schedule for the required volume. Common payment methods such as T/T in advance or LC at sight are used in China‑based chemical trade and should be agreed in writing.
Upon receipt, perform a visual inspection of container integrity and compare a sample against the supplied certificate of analysis. A third‑party laboratory can conduct a quantitative assay for HEDP, HEDPNa4 and iron content to ensure compliance with the listed specifications. Retain the safety data sheet, test reports and any inspection certificates as part of the import documentation for customs clearance and internal quality records.
