Rock Wool Insulation Batts 24-inch Wide
These rock wool batts, made from spun molten rock fibers, measure 24 inches (61 cm) in width and are designed for thermal and sound insulation in residential walls. They fall under HTS 6806.10.00.40 as slag wool, rock wool or similar mineral wools in batt form exceeding 61 cm in width, excluding those of headings 6811, 6812 or chapter 69. The loose fibrous structure provides excellent heat-insulating and sound-absorbing properties.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing exfoliated vermiculite or expanded clays
Mixtures with vermiculite or expanded mineral materials shift to the separate subheading for those specific expanded products.
If formed into rigid panels or boards
Celite or cellular mineral products like rigid fiberboards are classified under Chapter 68 heading 6811, not loose batts.
If in rolls or sheets rather than discrete batts
The hierarchy distinguishes rolls/sheets from 'other' forms like batts; width criterion applies similarly but form changes subheading.
