5407.91.20.10 - Mixed mainly or solely with artificial filaments (620)

This HTS category, 5407.91.20.10, specifically classifies woven fabrics of synthetic filament yarn that are not of man-made staple fibers (as defined in heading 5406) and are not made predominantly from glass filaments. The "Other" designation at this level signifies that these fabrics do not fall under more specific subheadings within the broader woven fabric categories of chapter 54. The key characteristic for classification here is that the fabric is composed of synthetic filaments, and it is presented either in an unbleached or bleached state.

The distinction from potential sibling categories lies in the exclusion of fabrics that might be specifically defined by their weave structure (e.g., twill, satin) or by their primary end-use if those are detailed in other subheadings. Furthermore, this category applies to fabrics where synthetic filaments are the principal component, as opposed to those where artificial filaments (as defined in note (620) to the tariff schedule) are the primary component, which would be classified elsewhere.

As this is a leaf node in the HTS classification system, there are no further subcategories for this specific code. Therefore, the classification is complete at this level, and imports or exports falling under this description would be coded as 5407.91.20.10. Practical classification relies on verifying the fabric composition as predominantly synthetic filament yarn, its unbleached or bleached condition, and the absence of specific weave or composition criteria that would place it into a more specialized heading or subheading.
