5407.53 - Of yarns of different colors:

This HTS category, 5407.53, specifically classifies woven fabrics of synthetic filament yarn, containing 85 percent or more by weight of textured polyester filaments, which are made of yarns of different colors. These fabrics are characterized by the presence of multiple colors within the yarn itself, distinguishing them from solid-colored or printed fabrics. The focus remains on woven constructions derived from synthetic filament yarn, aligning with the broader scope of heading 5407.

Unlike its sibling categories, 5407.53 is not defined by its bleaching status (5407.51), whether it is dyed (5407.52), or if it has undergone printing (5407.54). Instead, this classification hinges on the multicolored nature of the constituent yarns. This means that fabrics with a blend of differently colored filaments, irrespective of whether they are ultimately dyed or printed after weaving, will fall under this subdivision, provided they meet the polyester filament content and weave requirements.

Within 5407.53, further distinctions are made based on thread count. Subcategory 5407.53.10.00 provides specific tariff treatment for fabrics with a warp thread count exceeding 69 but not more than 142 per centimeter and a filling thread count over 31 but not more than 71 per centimeter. This precise measurement of yarn density is a key factor in determining the exact classification for these multicolored polyester woven fabrics, allowing for granular differentiation based on textile construction.
