Import Caustic Soda — Buy in Bulk from Supplier in China

Caustic soda, also known as sodium hydroxide (NaOH) with a molecular weight of 40.00, is supplied by Zhengzhou Longfield International Co., Ltd in solid and liquid forms. The solid variant is available as white flakes, pearls, or granular forms, while the liquid form is a colourless transparent solution. The solid product is packaged in 25 kg three-layer PP and PE plastic bags or 200 kg iron drums with a height of 90 cm, catering to bulk industrial needs.

This sodium hydroxide meets industrial-grade specifications with NaOH purity levels of 96%, 98%, and 99%, each with controlled impurities such as sodium carbonate (Na2CO3) ranging from 0.90% to 1.40%, sodium chloride (NaCl) from 0.15% to 2.80%, and iron oxide (Fe2O3) from 0.007% to 0.01%. The pure product has a relative density of 2.130, a melting point of 318.4°C, and a boiling point of 1390°C, ensuring stability under typical industrial storage conditions.

Primarily used in papermaking, cellulose production, and soap manufacturing, caustic soda also serves in textile processing, pharmaceuticals, and vegetable oil refinement. Buyers typically source this chemical for its strong alkaline properties, which are critical in pH regulation and organic material breakdown. Industrial users should confirm compatibility with their processes, as the solid form is fragile and requires careful handling to prevent degradation.

Zhengzhou Longfield International Co., Ltd is based in Zhengzhou, Henan Province, China, with its registered address at No.130, Huangheroad, 403 Zhengzhou 450003. The company operates as an importer tier supplier, specialising in the distribution of industrial chemicals including caustic soda. Its profile indicates a focus on providing chemical products tailored to bulk industrial applications, with a presence in the Henan region.

The supplier currently holds a harbor trust tier, reflecting a baseline level of verification. However, its response rate is listed as 0.00%, which may indicate limited engagement or a need for buyers to follow up directly for inquiries. The company’s offering is structured around the provision of sodium hydroxide in multiple purity grades, with clear specifications provided for each variant to meet diverse industrial requirements.
