Overview

This HTS category, 6806.90.00.90, covers "Other" articles of heat-insulating, sound-insulating, or sound-absorbing mineral materials. This classification is specifically for products that fall under the broader scope of heading 6806 but are not explicitly defined by other subheadings. These goods are typically manufactured from mineral wools, exfoliated vermiculite, expanded clays, foamed slag, or similar expanded mineral materials. Their primary function is to provide thermal, acoustic insulation, or sound absorption in various applications.

This subheading distinguishes itself from its sibling, 6806.90.00.20 ("Of molded calcium silicate"), by excluding products made from molded calcium silicate. Therefore, any heat-insulating, sound-insulating, or sound-absorbing articles composed of other mineral materials, and not specifically covered elsewhere, would be classified here. Examples could include pre-formed insulation shapes made from rock wool or expanded perlite that are not calcium silicate-based and do not fit into more specific subcategories within 6806.

As this is a leaf node, there are no subcategories to introduce. Classification within this subheading hinges on the fact that the product is an article of heat-insulating, sound-insulating, or sound-absorbing mineral material falling under heading 6806, and it is not a molded calcium silicate product. The key is to confirm that the material composition and intended function align with the broader heading, while ensuring it does not meet the criteria for more specific classifications.
