6104.39 - Of other textile materials:

Category 6104.39.00.00 specifically classifies women's or girls' suit-type jackets and blazers that are knitted or crocheted and are made of textile materials other than wool, fine animal hair, cotton, or synthetic fibers. This means it captures garments constructed from materials like silk, linen, ramie, or blends not predominantly composed of the excluded fibers.

Unlike its sibling categories, 6104.31.00.00 (wool or fine animal hair), 6104.32.00.00 (cotton), and 6104.33 (synthetic fibers), this category serves as a residual classification for suit-type jackets and blazers made from a diverse range of other natural and man-made textile fibers. The key differentiator is the fiber composition, excluding the specific materials that are assigned to the other headings within the 6104.3 series.

Within this category, further subdivisions exist to refine classification based on specific material types. Subcategory 6104.39.10.00 addresses garments made from artificial fibers, distinguishing them from other "other textile materials" captured under 6104.39.20. This hierarchical structure ensures precise tariff treatment by accounting for the specific origins and properties of the materials used in these knitted or crocheted outerwear pieces.
