2516.90.00.30 - Having a thickness of 7.5 cm or more

This HTS category, 2516.90.00.30, specifically classifies "other monumental or building stone" that has been processed to have a thickness of 7.5 centimeters or more. This designation applies to various types of stone beyond granite, porphyry, basalt, and sandstone, which are detailed in preceding HTS subheadings within 2516. The key distinguishing factor for this classification is the substantial thickness, indicating its intended use as substantial building blocks, monumental elements, or large-format dimension stone.

It is crucial to distinguish this category from its sibling, 2516.90.00.60, which covers "Other" monumental or building stone without the specified minimum thickness requirement. Therefore, if a piece of "other" monumental or building stone is less than 7.5 cm thick, it would fall under the 2516.90.00.60 category, even if it shares the same material composition. The thickness criterion is a definitive physical characteristic that separates these two classifications at this level of detail.

As a leaf node, this category does not have further subcategories. Classification under 2516.90.00.30 is final once the stone is identified as "other" monumental or building stone and meets the 7.5 cm or greater thickness requirement. Examples of stones that might be classified here include large blocks or slabs of slate, marble, or other suitable dimension stones that are not specifically covered by the more narrowly defined categories but are intended for construction or monumental purposes and meet the specified thickness.
