Overview
This HTS category, 6806.90.00.20, specifically covers articles of heat-insulating, sound-insulating, or sound-absorbing mineral materials that are composed of molded calcium silicate. These products are manufactured from calcium silicate that has been formed into a specific shape, distinguishing them from loose or unbound mineral wools or expanded materials found in other parts of heading 6806. The molding process allows for the creation of articles with defined dimensions and often complex geometries, designed for specialized insulation applications in industrial settings, construction, or equipment.
Within the broader "Other" category under 6806.90, this subdivision is set apart by its specific material composition and manufacturing process. While 6806.90.00.90 encompasses all other articles of heat-insulating, sound-insulating, or sound-absorbing mineral materials not covered by the molded calcium silicate specification, this category is precisely defined by the use of calcium silicate in a molded form. The classification hinges on the material being calcium silicate and the product being a molded article, excluding loose fill materials or those made from other mineral compositions.
As this is a leaf node in the HTS classification, there are no further subdivisions. Therefore, the primary focus for classification within 6806.90.00.20 is to ensure the article meets the criteria of being made from molded calcium silicate and intended for thermal, acoustic insulation, or sound absorption purposes, while also falling outside the scope of headings 6811 or 6812, or Chapter 69.
