As a fundamental inorganic chemical raw material, high-purity calcium carbide (CaC2) plays a critical role in global industrial manufacturing, metal fabrication, and chemical synthesis. Sourced directly from premier manufacturing facilities in energy-rich production zones, our premium-grade calcium carbide features uniform lump sizes, low impurity concentrations (minimal sulfur and phosphorus), and consistent acetylene gas yields.
Whether you are seeking bulk supply for acetylene gas generation, steelmaking desulfurization, or organic chemical processing, obtaining a transparent and competitive calcium carbide price per kg is paramount for optimizing your enterprise supply chain. We provide factory-direct pricing, flexible dangerous goods (DG) logistics solutions, and strict Quality Assurance (QA) protocols to meet the stringent demands of international commercial buyers.
Our industrial calcium carbide is produced via high-temperature electro-thermal smelting of high-purity quicklime and carbon materials. Every batch undergoes rigorous lab analysis to ensure compliance with international standard parameters.

When evaluating the market, the baseline calcium carbide price per kg correlates directly with the minimum gas yield (L/kg) and grain size uniformity. Higher gas yield grades reduce operational downtime in downstream acetylene generators, maximizing cost-effectiveness per metric ton processed.
Over 75% of global calcium carbide is consumed in reaction with water to yield acetylene gas (C2H2), a vital hydrocarbon used extensively in oxy-acetylene welding, thermal cutting, and precision flame profiling.
In modern metallurgy, calcium carbide serves as a powerful desulfurizing agent in iron and steel ladles. It reacts efficiently with molten steel to remove sulfur impurities, improving steel ductility, toughness, and chemical purity.
It acts as a primary feedstock for producing vinyl chloride monomer (VCM), polyvinyl chloride (PVC) resins, calcium cyanamide (synthetic fertilizer), and various organic intermediates in modern petrochemical plants.
Calcium carbide reacts vigorously with moisture to liberate flammable acetylene gas. Thus, proper packaging and international transport compliance are non-negotiable.
Hazard Classification: Class 4.3 (Dangerous When Wet) | UN Number: UN 1402 | Packing Group: PG I / PG II
Standard Packaging: 50 kg or 100 kg hermetically sealed steel drums, flushed with dry nitrogen gas to prevent ambient humidity exposure.
Custom Packaging: Sealed iron drums placed on reinforced wooden pallets, securely shrink-wrapped with hazard labeling compliant with IMDG/ICAO standards.
Storage Advice: Store in a cool, dry, well-ventilated dedicated chemical warehouse away from heat sources, open flames, and water sources.
When sourcing industrial chemicals, negotiating an accurate calcium carbide price per kg involves factoring in several key dynamic variables:
Volume & Order Scale: Bulk orders (FCL - Full Container Load, typically 22.5 MT per 20ft container) unlock substantial volume discounts.
Gas Yield Level: Premium grades (305L/kg) command a slight premium over standard grades due to higher raw material purity and lower energy-to-output ratios.
Packaging Requirements: Standard 50kg new steel drums vs. specialized palletized configurations impact final FOB/CIF pricing.
Dangerous Goods Freight Rates: International hazmat shipping surcharges vary by destination port and carrier availability.
Minimum Order Quantity (MOQ): 20 Metric Tons (1 x 20' FCL)
Incoterrms Offered: FOB, CFR, CIF, DDP (Select ports)
Payment Terms: T/T (Telegraphic Transfer), Irrevocable L/C at Sight
Lead Time: 15–20 days after receipt of advance deposit or formal L/C
