Importing Calcium Carbide UN 1402: What Buyers Need to Know

Key considerations before booking: UN classification, moisture protection, packaging integrity and safe handling. January 30, 2026 When importing calcium carbide, product quality is only one part of the equation. Because calcium carbide is classified as dangerous goods, proper packaging, documentation and moisture control are equally important throughout transportation and handling. For international shipments, calcium carbide is generally transported under: UN No.: UN 1402 Proper Shipping Name: CALCIUM CARBIDE Hazard Class: 4.3 – Substances which, in contact with water, emit flammable gases Packing Group: II, where applicable to the shipment Sea transport: Subject to the applicable IMDG Code requirements The main hazard is not spontaneous ignition. Calcium carbide reacts with water and produces acetylene gas, which is highly flammable. For this reason, keeping the cargo dry is one of the most important safety requirements during storage and transportation. 1. Check that dangerous goods information is consistent A calcium carbide shipment involves…

Downstream Applications of Calcium Carbide

Calcium carbide (CaC₂) is an important industrial raw material with a wide range of downstream applications. Its ability to generate acetylene gas makes it particularly valuable in the chemical and metal industries. 1. Acetylene Gas Production One of the most important uses of calcium carbide is the production of acetylene (C₂H₂). When calcium carbide reacts with water, it produces acetylene gas, which is widely used for: Gas welding and cutting Metal fabrication Chemical synthesis Industrial gas production 2. PVC and Vinyl Production Acetylene produced from calcium carbide can be further processed into vinyl chloride monomer (VCM), which is an important raw material for PVC production. This route remains significant in regions where coal and calcium carbide are readily available. 3. Chemical Manufacturing Calcium carbide and acetylene are used as feedstocks for producing various chemicals and organic compounds, including materials used in plastics, solvents, and other industrial products. 4. Steel and…

What Affects the Price of Calcium Carbide?

Calcium carbide (CaC₂) is an important industrial raw material used in acetylene production, chemical manufacturing, steel processing and other applications. When buyers compare calcium carbide suppliers, price is naturally one of the first things they consider. However, the price of calcium carbide is affected by several factors, and the lowest price does not always mean the lowest overall cost. 1. Calcium Carbide Quality Quality is one of the most important factors affecting calcium carbide prices. Different products can have different levels of purity, moisture and impurities. Higher-quality calcium carbide generally provides more stable performance during use. For buyers, it is important to compare quality specifications and actual performance, rather than looking only at the price per ton. 2. Gas Yield For customers using calcium carbide to produce acetylene, gas yield is especially important. A higher gas yield means that less calcium carbide may be required to produce the same amount…

Why Calcium Carbide Remains Essential to Modern Industry

From acetylene generation to steel desulfurization, calcium carbide continues to support essential industrial processes Calcium carbide (CaC₂) is not usually the material that attracts the most attention in the chemical industry. It is a traditional industrial raw material, and its chemistry has been understood for more than a century. Yet its importance is easy to recognize in the industries that depend on it. In acetylene production, the quality of calcium carbide directly affects gas generation and operating stability. In steelmaking, specially sized carbide can be used as a desulfurizing reagent to help control sulfur levels in molten iron. Behind these applications is a simple but important requirement: the material must perform consistently in real production conditions. For calcium carbide suppliers, this means quality is not determined by a chemical formula alone. Particle size, gas yield, impurity control, packaging, storage, and delivery reliability can all influence the customer's actual production experience.…
