As a leading ISO-certified calcium carbide manufacturer, we deliver premium-grade CaC2 directly from our electro-thermal smelting facility to global buyers. Our calcium carbide features uniform lump sizes 7-15mm, high chemical purity (80%-90%), and a guaranteed minimum gas yield of 285 L/kg. By eliminating intermediaries, we ensure competitive volume pricing, flexible OEM drum branding, and reliable FCL shipping for acetylene gas producers and metalworking enterprises worldwide.
As a leading and certified calcium carbide manufacturer, we specialize in the large-scale production, refining, and international export of high-purity industrial grade calcium carbide ($\text{CaC}_2$). Operating advanced high-temperature electro-thermal smelting furnaces, we convert premium quicklime and carbon materials into top-tier chemical stone known for its consistent quality, uniform lump sizing, and high gas yield.
Whether your operations require feedstock for acetylene gas generation, effective desulfurization agents for steel manufacturing, or key chemical intermediates for PVC production, sourcing directly from an established calcium carbide manufacturer ensures uncompromised quality, competitive factory pricing, and full supply chain stability.
To meet the rigorous demands of modern industrial processing, every batch from our facility undergoes comprehensive laboratory quality testing before dispatch.

Partnering with a reliable calcium carbide manufacturer guarantees high gas evolution rates per metric ton, which drastically reduces operational downtime and residual lime slurry in downstream gas generators.
Over 75% of global calcium carbide is hydrolyzed to produce acetylene gas (C2H2), a crucial fuel gas utilized worldwide in oxy-acetylene torch welding, thermal flame cutting, and metal profiling.
In modern metallurgy, steelmakers utilize our fine carbide granules and crushed lumps as an efficient desulfurizer in molten iron and steel ladles. It quickly reacts with sulfur impurities to enhance the ductility, tensile strength, and purity of final steel products.
Our chemical-grade carbide stone serves as a foundational building block for manufacturing vinyl chloride monomer (VCM), polyvinyl chloride (PVC) resins, calcium cyanamide fertilizers, and synthetic rubber derivatives.
Because calcium carbide reacts rapidly with ambient moisture to liberate flammable acetylene gas, safety compliance and airtight packaging are paramount. As an experienced calcium carbide manufacturer, we enforce strict International Maritime Dangerous Goods (IMDG) packing standards:
Hazard Classification: Class 4.3 (Dangerous When Wet) | UN 1402 | Packing Group I/II
Standard Packaging: 50 kg or 100 kg heavy-duty steel drums, hermetically sealed and nitrogen-purged to eliminate humidity risks during long-distance shipping.
Palletized Delivery: Drums are securely mounted on reinforced, heat-treated wooden pallets, shrink-wrapped, and strapped for high-seas vessel transit.
Minimum Order Quantity (MOQ): 20 Metric Tons (1 x 20' Full Container Load)
Supported Incoterms: FOB, CFR, CIF, DDP (To major commercial ports)
Payment Terms: T/T (Telegraphic Transfer), Irrevocable L/C at sight
Export Documentation Provided: Certificate of Analysis (COA), Material Safety Data Sheet (MSDS), UN Packaging Certificate, Commercial Invoice & Bill of Lading
As a dedicated calcium carbide manufacturer, we accommodate custom grain sizes, flexible drum color branding, and long-term supply contracts for global industrial buyers.
