HS Code for Calcium carbide

Calcium carbide is classified under Harmonized System (HS) code 2849.10. This classification is straightforward, as the HS description explicitly states "Carbides; of calcium, whether or not chemically defined." This places calcium carbide within Chapter 28, which covers inorganic chemicals. The specific subheading 2849.10 is dedicated solely to calcium carbide, recognizing its distinct chemical identity and industrial significance. The phrase "whether or not chemically defined" ensures that both pure and technical grades of calcium carbide are included under this single code, simplifying its international trade classification.

Products Included

• Technical grade calcium carbide lumps or powder.
• Chemically pure calcium carbide.
• Calcium carbide used for acetylene gas production.
• Calcium carbide for desulfurization in metallurgy.

Common Misclassification

Calcium carbide might be confused with other carbides, such as silicon carbide (HS 2849.20) or other carbides (HS 2849.90). The key differentiator for HS 2849.10 is the specific chemical element "calcium" forming the carbide. Misclassification could occur if the "of calcium" specificity is overlooked, leading to its erroneous placement under general carbide categories or other inorganic compounds. It is crucial to verify that the product is indeed a carbide of calcium and not another metallic or non-metallic carbide.

FAQ

What is the HS code for Calcium carbide?

The HS code for Calcium carbide is 2849.10, which specifically covers "Carbides; of calcium, whether or not chemically defined."

What are the primary industrial uses of Calcium carbide?

Calcium carbide is primarily used in the production of acetylene gas, which is utilized in welding and cutting applications, and as a chemical feedstock. It is also employed in the steel industry for desulfurization and as a deoxidizer.
