6217.90.90.20 - Other (840)

This HTS classification, 6217.90.90.20, specifically covers "Other" parts of blouses and shirts. It encompasses a broad range of components that are not explicitly listed under more specific material-based subheadings within heading 6217.90.90. These could include, for example, specialized interlinings, decorative elements not otherwise specified, or components made from materials not falling under cotton, wool, or man-made fibers.

The key differentiator for this category lies in its residual nature. Unlike its siblings such as 6217.90.90.03 (Of cotton), 6217.90.90.05 (Of wool or fine animal hair), and 6217.90.90.10 (Of man-made fibers), this subheading is intended for parts where the primary textile material does not fit neatly into those defined categories or where the material composition is mixed in a way that precludes classification under a single fiber type.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Therefore, precise classification under 6217.90.90.20 hinges on the careful examination of the material composition and the absence of a more specific classification based on fiber content for the particular part of a blouse or shirt.
