5407.43 - Of yarns of different colors:

This category, HTS code 5407.43, encompasses woven fabrics of synthetic filament yarn, specifically those containing 85 percent or more by weight of filaments of nylon or other polyamides. The defining characteristic of fabrics classified under 5407.43 is that they are made of yarns of different colors, creating a multi-colored appearance. This distinguishes them from their siblings: 5407.41 (unbleached or bleached), 5407.42 (dyed a single color), and 5407.44 (printed with designs).

Fabrics classified here are woven from synthetic filaments, primarily nylon or other polyamides, and feature a color pattern resulting from the use of yarns of varying colors. This deliberate combination of different colored yarns during the weaving process is the key identifier for this sub-heading.

Within 5407.43, further distinctions are made based on the fabric's construction, specifically its thread count. Subcategory 5407.43.10.00 covers fabrics with a specific warp and filling thread count range, while 5407.43.20 encompasses all other woven fabrics of different colored nylon or polyamide yarns not meeting that precise thread count specification. These subdivisions allow for more granular classification based on the fabric's density and weave structure.
