Import Calcium Carbide — Buy in Bulk from Supplier in China

Calcium carbide from Greatest Chemical Industry Limited is supplied under the GB10665-2004 standard, with grades ranging from Superfine to Second Grade. Superfine grade delivers a gas yield of 305 L/kg, while First Grade ranges between 295-305 L/kg and Second Grade between 285-295 L/kg. Phosphine content in acetylene is capped at 0.06% for Superfine, 0.08% for First and Second Grade, and hydrogen sulfide content is consistently limited to 0.1% across all grades.

The material is a greyish-black solid with a strong garlic-like odour, typically produced in lump or granular form for industrial use. Calcium carbide reacts with water to produce acetylene gas, a key feedstock for chemical synthesis, welding, and cutting applications. The product’s purity and gas yield are critical for efficient acetylene generation, with lower-grade material often used in less demanding applications where gas output is less stringently controlled.

This product is primarily used in the production of acetylene for industrial welding and cutting, as well as in the synthesis of organic compounds like polyvinyl chloride (PVC). Buyers in the metal fabrication, chemical manufacturing, and construction sectors source calcium carbide in bulk, with packaging options including 250kg, 100kg, or 50kg new iron drums filled with nitrogen to prevent degradation. Greatest Chemical Industry Limited offers drum colours in green, gray, or black to meet specific handling or branding requirements.

Greatest Chemical Industry Limited is based in Tianjin, China, with its office located at Room 1104, Unit A, Wan Long Center Building. The supplier is classified under the imported tier, indicating a focus on international trade and export capabilities. Its harbor trust tier suggests a baseline level of verification, though the response rate and average response hours are currently listed as zero, which may indicate limited engagement or recent listing status.

The company specialises in chemical products, with calcium carbide as a key offering. While the profile does not provide details on production capacity, certifications, or client history, the supplier’s adherence to the GB10665-2004 standard for calcium carbide demonstrates a commitment to recognised industry specifications. Buyers are advised to confirm additional details such as lead times, minimum order quantities, and quality control processes directly with the supplier.
