2505.90.00.00 - Other

This category, HTS 2505.90.00.00, encompasses natural sands that are not specifically classified under other headings within Chapter 25. It serves as a residual category for all other types of natural sands, regardless of color, as long as they are not metal-bearing sands classified under Chapter 26. Examples of goods that would fall under this classification include, but are not limited to, common construction sands, beach sands used for recreational purposes, or specialized industrial sands that do not fit into more specific subheadings.

It is crucial to distinguish this "Other" category from its sibling, HTS 2505.10, which specifically covers silica sands and quartz sands. While silica and quartz sands are indeed natural sands, their distinct chemical and physical properties, often leading to specialized industrial applications like glass manufacturing or foundry work, necessitate their separate classification. Therefore, any natural sand that does not primarily consist of silica or quartz in quantities that would warrant classification under 2505.10 will likely be directed to this residual category.

As this is a leaf node, there are no further subcategories to introduce. Classification at this level relies heavily on the exclusion principle, meaning that if a natural sand does not meet the criteria for silica sands and quartz sands (2505.10) and is not a metal-bearing sand (Chapter 26), it will be classified here. Careful examination of the sand's composition and intended use, in conjunction with the overarching scope of Chapter 25, is essential for accurate determination.
