2523.21.00.00 - White cement, whether or not artificially colored

This HTS classification, 2523.21.00.00, specifically addresses white Portland cement. This category encompasses hydraulic cement that is predominantly white in color, often achieved through the careful selection of raw materials and controlled manufacturing processes. It includes white cement that may be naturally white or artificially colored to achieve a specific hue, while still maintaining the fundamental characteristics of Portland cement. The intended use of this material is typically for applications where aesthetic appearance is a primary concern, such as decorative concrete, architectural finishes, and specialized construction projects.

Within the broader heading of Portland cement (2523.2), this subcategory, 2523.21.00.00, is distinguished from its sibling, 2523.29.00.00 ("Other"). The defining characteristic for classification here is the color white. While both categories fall under Portland cement, 2523.21.00.00 is exclusively for cement whose primary visual attribute is its whiteness, regardless of any artificial coloring. The sibling category, 2523.29.00.00, would therefore cover all other Portland cements that are not white, including various shades of gray or those with other specific non-white colorations or compositions not meeting the white cement definition.

As this is a leaf node in the HTS database, there are no further subcategories for 2523.21.00.00. Classification at this level is determined by the presence of the specific physical characteristic of being white cement. Therefore, any product meeting the definition of white Portland cement, whether naturally white or artificially colored, should be classified under this code. The practical application for customs purposes is to identify shipments based on this distinct visual property, differentiating them from other types of Portland cement.
