2511.10.10.00 - Ground

This HTS classification, 2511.10.10.00, specifically covers natural barium sulfate, commonly known as barytes, when it has been processed through grinding. Barytes are naturally occurring minerals that are primarily composed of barium sulfate (BaSO4) and are valued for their high specific gravity and inert chemical properties. The "Ground" designation signifies that the barytes have undergone mechanical processing to reduce their particle size, making them suitable for various industrial applications.

This category is distinguished from its sibling, 2511.10.50.00 ("Other"), by the specific physical form. While both fall under natural barium sulfate, 2511.10.10.00 strictly applies to barytes that have been ground. The "Other" category would encompass natural barium sulfate that has not been ground, such as crushed or unpulverized ore. This distinction is crucial for accurate tariff application, as the processing method can affect the material's utility and market value.

As this is a leaf node, there are no further subcategories within 2511.10.10.00. The classification is finalized at the point of ground natural barium sulfate. Classification in this subheading is determined by the mineralogical identity as natural barium sulfate and the physical state of being ground, irrespective of any further processing or purification, as long as it remains fundamentally barytes.
