6815.19.00.00 - Other

This classification, HTS 6815.19.00.00, encompasses articles made of mineral substances that are not specifically enumerated in preceding subheadings of heading 6815. It serves as a residual category for items primarily composed of mineral materials, excluding those explicitly covered elsewhere within the heading. The "Other" designation signifies that goods falling under this code do not fit the more specific descriptions of carbon fibers, fabrics of carbon fibers, or other articles of carbon fibers for non-electrical uses.

This subheading distinguishes itself by encompassing articles made from mineral substances that are not primarily carbon fiber based. For instance, this could include articles formed from materials like mica, asbestos, or other mineral composites, provided they are not otherwise classified. It is crucial to differentiate these from the preceding subheadings which specifically detail various forms and applications of carbon fibers.

As a leaf node within the HTS structure, HTS 6815.19.00.00 has no further subcategories. Therefore, classification within this code relies on thoroughly excluding the goods described in the preceding subheadings (6815.11, 6815.12, and 6815.13) and confirming that the article is indeed made of stone or other mineral substances, not elsewhere specified or included, and is intended for non-electrical uses. Examples might include specialized refractory bricks made of mineral aggregates or molded mineral composite parts not utilizing carbon fibers.
