2505.10.50.00 - Other 🖩

This HTS category, 2505.10.50.00, specifically addresses "Other" natural sands of all kinds, whether or not colored, that fall under the broader classification of silica sands and quartz sands. It encompasses silica and quartz sands that do not meet the specific compositional requirements of sibling categories. The key differentiator lies in the chemical and physical properties of the sand.

Unlike the sibling category 2505.10.10.00, which is designated for sands with a very high silica content (95% or more) and a low iron oxide presence (0.6% or less), this "Other" category is for silica and quartz sands that deviate from these precise specifications. This could include sands with a lower percentage of silica, a higher percentage of iron oxide, or the presence of other significant impurities or constituent minerals that preclude their classification under the more restrictive subheading.

Given that this is a leaf node within the HTS, there are no further subcategories. Therefore, the classification hinges on a thorough analysis of the sand's composition, particle size, color, and intended use to ensure it is correctly placed here and distinct from other natural sand classifications within Chapter 25. This category serves as a residual classification for silica and quartz sands that do not fit into more narrowly defined subheadings.
