2516.90.00 - Other monumental or building stone

This HTS category, 2516.90.00, encompasses "Other monumental or building stone." It serves as a residual classification for natural stones not specifically enumerated in the preceding subheadings of heading 2516. This includes a broad range of stones that are used for construction, architectural purposes, or as monumental material. The defining characteristic is their suitability for these applications, regardless of whether they have been roughly trimmed or simply cut into blocks or slabs of a rectangular shape.

Unlike its siblings, 2516.10 (granite) and 2516.20 (sandstone), this category is not limited to a specific type of stone. It covers other natural stones such as marble, slate, travertine, and various types of igneous, metamorphic, or sedimentary rocks that meet the criteria for monumental or building use but are not classified under the more specific categories. The key differentiator is the absence of a specific HTS subheading for the particular type of stone in question, provided it possesses the properties suitable for monumental or building applications.

Within this category, two subcategories exist to further refine classification based on physical dimensions. Subheading 2516.90.00.30 specifically applies to such stones when they have a thickness of 7.5 cm or more, indicating a use in structural or substantial applications. The residual subheading, 2516.90.00.60, covers all other monumental or building stones not meeting the thickness requirement of the preceding subheading. This distinction allows for more precise tariff application based on the size and intended application of the stone products.
