HS Code for Aluminous cement

Aluminous cement, also widely known as ciment fondu or calcium aluminate cement, is classified under HS code 252330. This classification is precise, directly identifying cement that is specifically "aluminous." The description further clarifies that this includes such cement whether it is colored or in the form of clinkers. The defining characteristic for this code is the chemical composition, specifically the high alumina content, which imparts unique properties compared to other types of cement. This distinct chemical makeup and resulting performance attributes, such as rapid hardening and resistance to chemical attack, are the primary reasons for its dedicated classification.

Common Misclassification

Aluminous cement is sometimes confused with other types of hydraulic cements. HS code 252329 covers other Portland cement, which is the most common type of cement but differs significantly in chemical composition and performance from aluminous cement. HS code 252390 encompasses other hydraulic cements not specifically provided for elsewhere, which might be a default if the specific "aluminous" characteristic is overlooked. The key differentiator for 252330 is the explicit mention of "aluminous" cement, referring to its high calcium aluminate content, which provides distinct properties such as high early strength, resistance to sulfates, and suitability for high-temperature applications, unlike standard Portland cements.

FAQ

What is the HS code for Aluminous cement?

The HS code for aluminous cement, also known as ciment fondu, whether or not colored or in the form of clinkers, is 252330.

What are the primary characteristics of aluminous cement?

Aluminous cement is primarily characterized by its high early strength development, excellent resistance to chemical attack (especially sulfates), and superior performance in high-temperature environments. These properties stem from its unique chemical composition, predominantly calcium aluminates, which differentiate it from Portland cement.
