5407.73 - Of yarns of different colors:

This HTS category, 5407.73, classifies woven fabrics that are primarily composed of synthetic filaments by weight (85% or more). Specifically, it encompasses woven fabrics where the yarns of different colors are utilized in the construction of the fabric. This distinguishes it from sibling categories such as 5407.71 (unbleached or bleached), 5407.72 (dyed in a single color), and 5407.74 (printed with designs). The key defining characteristic here is the presence of multiple yarn colors woven together to create the fabric's appearance, rather than a uniform dyed or printed pattern.

Within this category, further subdivisions are made based on the fabric's construction, specifically its thread count. Subcategory 5407.73.10.00 covers fabrics with a specific thread density, defined by a warp thread count exceeding 69 but not exceeding 142 per centimeter, and a filling thread count exceeding 31 but not exceeding 71 per centimeter. This precise measurement is crucial for differentiating fabrics with finer weaves from those with a coarser construction.

The remaining portion of this category falls under 5407.73.20, designated as "Other." This encompasses all woven fabrics of synthetic filament yarns containing yarns of different colors, that meet the general criteria of 85% synthetic filament content, but do not conform to the specific thread count parameters outlined in 5407.73.10.00. This allows for the classification of a broad range of multi-colored synthetic woven fabrics that do not fit the more narrowly defined thread count specification.
