6806.10.00.20 - Batts, not exceeding 61 cm in width

This HTS category, 6806.10.00.20, specifically classifies batts of slag wool, rock wool, or similar mineral wools that do not exceed 61 centimeters in width. These materials are primarily used for thermal and acoustic insulation applications. The defining characteristic for classification under this code is the width of the batt, a crucial physical attribute that dictates its suitability for specific installation methods and spaces.

Distinguishing this category from its siblings is essential for accurate classification. While 6806.10.00.40 also covers batts of mineral wool, it applies to those exceeding 61 cm in width. Furthermore, 6806.10.00.60 is designated for pipe coverings, which are specifically shaped to fit around cylindrical structures, and 6806.10.00.90 encompasses any remaining mineral wool products not otherwise specified, including bulk forms or other specialized articles.

As a leaf node, this category does not have further subcategories. Therefore, accurate classification relies on precisely meeting the description's criteria: the material being slag wool, rock wool, or a similar mineral wool, presented in batt form, and crucially, having a width of 61 centimeters or less. Examples include insulation batts commonly found in residential and commercial construction for walls, ceilings, and floors where narrower widths are required for fitting.
