6806.10.00.40 - Batts, exceeding 61 cm in width

This HTS classification covers mineral wool products, specifically batts derived from slag wool, rock wool, or similar mineral compositions. These materials are manufactured in a batt form, designed for insulation purposes. The defining characteristic for this code is that these batts exceed 61 centimeters in width. This broad width is often utilized in applications requiring extensive coverage and efficient installation across large surfaces.

This category is distinguished from its siblings by its specific width parameter. HTS 6806.10.00.20 covers similar mineral wool batts that do *not* exceed 61 cm in width, differing solely on this dimensional threshold. HTS 6806.10.00.60 specifically enumerates pipe coverings, which are also typically made from mineral wool but are shaped for fitting around cylindrical objects. Lastly, HTS 6806.10.00.90 serves as a residual category for other mineral wool items not fitting the specified batts or pipe coverings.

As this is a leaf node, there are no further subcategories. Therefore, the classification hinges entirely on the material (slag wool, rock wool, or similar mineral wools), the form (batts), and the specific width criterion (exceeding 61 cm). Importers should ensure that the documented width of the goods accurately matches this requirement to ensure correct classification.
