Are you looking to optimize your industrial chemical procurement and secure a reliable, long-term partner? Welcome to Tianjin Zhongying Chemical Co., Ltd., China’s leading industrial-grade calcium carbide manufacturer. Located in the chemical-rich production belt of Inner Mongolia with a dedicated maritime logistics branch near Tianjin Port, we are a true source factory that eliminates trading intermediates.
If you are a global procurement manager calculating your quarterly overhead, you know that minimizing your raw calcium carbide cost without sacrificing chemical purity is the key to maintaining healthy profit margins. We provide a transparent, competitive tier-structured calcium carbide cost model backed by premium, battle-tested manufacturing. With an annual facility output of 70,000 metric tons and a powerful, localized shipping matrix capable of loading and dispatching 10 full 20ft containers every single day, we guarantee absolute supply continuity that your business can rely on.
Our large-lump 50-80mm calcium carbide is produced using premium raw lime and petroleum coke processed in high-intensity electric arc furnaces.

In heavy industrial procurement, small-scale retailing inflates your operational expenses. When international distributors inquire about our factory-direct calcium carbide cost, we provide a fully itemized invoice. This structure itemizes the pure material weight cost, the structural steel drum manufacturing cost, and ocean freight calculations.
By cutting out regional trading brokers, export agents, and logistical middlemen, you secure the lowest possible calcium carbide cost per metric ton. Our Minimum Order Quantity (MOQ) is one full 20ft container (22.5 Net Metric Tons). Purchasing by the container load maximizes sea freight efficiency and lowers the overall landed cost per unit, helping your company remain competitive in its local distribution network.
Our 50-80mm calcium carbide represents our flagship heavy-lump classification. This coarse sizing is highly requested by global heavy industries due to its distinctive physical degradation advantages:
Sustained, Controlled Acetylene Release: The lower surface-area-to-mass ratio of 50-80mm lumps ensures a steady, manageable reaction speed inside automated acetylene gas generators. It avoids the rapid pressure spikes associated with finer granules.
Extended Burn Time: For mining applications and legacy carbide illumination systems, 50-80mm pieces breakdown slower, delivering long-term gas generation efficiency.
Reduced Fine Sludge Waste: Large-lump profiles generate less powdery residue, facilitating cleaner separation inside industrial hydrolysis machinery.
Acetylene Gas Plants ($C_2H_2$): Serving as the core chemical feedstock for generating high-purity acetylene gas utilized in metal cutting, precision industrial welding, and alloy fabrication.
Steelmaking & Desulfurization: Injected into molten iron processing systems within modern steel mills as a potent deoxidizer and desulfurizing agent to eliminate trace sulfur impurities.
Chemical Synthesis Manufacturing: Providing the carbon-calcium backbone needed to synthesize PVC (Polyvinyl Chloride) resins, synthetic rubbers, chloroprene, and agricultural calcium cyanamide fertilizers.
Because $CaC_2$ reacts with atmospheric moisture to release volatile, flammable gases, our packaging is built for maximum protection. We pack our 50-80mm lumps inside brand-new, vacuum-tested, nitrogen-sealed steel drums.
The 50KG steel drum is our primary export packaging standard due to its excellent structural balance and universal utility.
Container Loading Profile: 450 steel drums are securely cross-braced per 20ft FCL, yielding exactly 22.5 Metric Tons net weight.
Handling Advantages: Perfectly optimized for regional markets where manual labor or manual tilting forklifts are used to load generators. The smaller 50KG volume ensures that if a drum is opened in high humidity, the contents are fully utilized before moisture degrades the rest of the material.
For large-scale industrial plants with integrated mechanical cranes and automated hopper feeding lines, we provide our heavy-duty 100KG steel drums.
Container Loading Profile: 225 steel drums per 20ft FCL, totaling 22.5 Metric Tons net weight.
Handling Advantages: Maximizes warehouse storage vertical spacing and cuts down on industrial unpacking waste during high-speed chemical feeding operations.
The calcium carbide cost quoted by our team includes complete branding and aesthetic structural customization at no additional fee:
11 Industrial Drum Colors: Select from 11 distinct RAL industrial paint shades (including standard forest green, deep yellow, solid black, steel grey, and sky blue). You can choose one universal color or use contrasting tones to differentiate multi-size mixed container shipments.
Permanent Painted Stenciling: Your company’s corporate logo, precise weight metrics, customized local hazard classifications, and destination port markers are painted directly onto the drum surfaces. We do not use paper labels that tear, mold, or wash away during transit.
Multi-Language Regulatory Layouts: Our layout teams regularly configure drum text layouts in English, Spanish, French, Portuguese, Arabic, Thai, Vietnamese, and Indonesian to ensure compliant local custom clearances.
A cheap chemical quote is meaningless if your supplier cannot deliver on time. Tianjin Zhongying Chemical has built a robust supply chain to support your continuous growth. With our advanced kilns and automated packing bays, we maintain the operational capacity to load up to 10 full 20ft containers every single day.
Strategically stationed under 5 kilometers from the main vessel loading berths of Tianjin Port, we bypass interior logistical bottlenecks. Our standard lead time from receipt of your initial deposit to the final container locking on the ship is just 14 days.
We provide reliable, long-term supply agreements to major chemical industrial hubs across the globe:
Africa: Supplying critical welding infrastructure and mining complexes across South Africa, Egypt, Nigeria, Algeria, Kenya, and Ghana.
South America: Fueling primary steel mill networks and chemical manufacturing plants in Brazil, Argentina, Colombia, Peru, and Chile.
Southeast Asia: Delivering high-volume chemical stocks to major manufacturing grids in Vietnam, Thailand, Indonesia, Malaysia, and the Philippines.
Europe: Delivering reliable industrial-grade chemical feedstocks to major distribution centers across Turkey, Poland, and surrounding regional trade zones.
Stop working with small brokers who compromise on gas yield and delivery speed. Partner directly with China's leading industrial-grade calcium carbide factory.
