Overview
This HTS category, 2523.90.00.00, encompasses "Other hydraulic cements" that do not fall under the more specific subheadings within the 2523.90 group. Hydraulic cements are binders that harden by reacting chemically with water, forming a durable, water-resistant compound. This classification is for those cements that exhibit hydraulic properties but are not explicitly listed as Portland cement, aluminous cement, slag cement, or supersulfate cement. Examples may include cements with specialized additives or formulations designed for particular construction applications.
Distinguishing this category from its siblings is crucial for accurate classification. While 2523.10.00.00 specifically covers cement clinkers, which are intermediate products in cement manufacturing, and 2523.30.00.00 deals with aluminous cements (characterized by a high alumina content), this category captures the remaining hydraulic cements. It serves as a residual classification for hydraulic cements that do not fit the distinct definitions of the other enumerated types.
As this is a leaf node, there are no further subcategories under 2523.90.00.00. Therefore, the focus for classification within this heading is on identifying whether a cement possesses hydraulic properties and ensuring it is not classifiable as Portland cement, aluminous cement, slag cement, or supersulfate cement. The presence of coloring agents or the form (e.g., powder or granular) does not preclude a product from being classified here, provided it meets the fundamental definition of a hydraulic cement not otherwise specified.
