Import Calcium Carbide — Buy in Bulk from Supplier in China

Calcium carbide from Tianjin Hengxinda Importer & Exporter Co., Ltd. delivers a gas yield of 295 litres per kilogram, a key metric for acetylene generation efficiency in industrial applications. The product is packaged in 100 kg steel drums, designed for bulk handling and safe transportation over long distances. The size specification of 50 to 80 mm ensures compatibility with standard industrial feed systems for acetylene production.

The material is industrial-grade calcium carbide (CaC2) with purity levels optimised for consistent acetylene output. Typical industry standards for such grades include a minimum CaC2 content of 75 to 80 percent, with phosphorus and sulfur impurities kept below 0.05 percent to prevent contamination in downstream processes. This grade is widely used in welding, metal cutting, and chemical synthesis due to its reliable reaction rate with water.

Primary buyers include welding workshops, steel mills, and chemical manufacturers that require a steady supply of acetylene for cutting, hardening, or as a feedstock for calcium cyanamide production. The product is shipped from Tianjin, a major chemical export hub in northern China, with Incoterms and payment terms negotiable per buyer requirements. Bulk orders benefit from the drum packaging, which reduces handling costs and minimises exposure to moisture during transit.

Tianjin Hengxinda Importer & Exporter Co., Ltd. operates from Rm 1109, Dagu Road, Hexi District, Tianjin, China. The company is registered as an importer and exporter, with a focus on bulk chemical commodities including calcium carbide. Its profile indicates a harbor trust tier, reflecting a baseline level of verification for international trade activities.

The supplier does not disclose response rates or average response times in its current profile, so buyers should expect to initiate contact directly for technical and logistical queries. The listing confirms the company’s role as a wholesaler of calcium carbide, with no additional claims about certifications, production capacity, or client references provided in the available data.
