9902.12.97 - Fabrics containing 85 percent or more by weight of textured polyester filaments, plain woven, of yarns of different colors, weighing 96 g/m2 or more but less than 170 g/m2, measuring 142.2 cm or more in width; such fabric with weft yarns of polybutylene terephthalate (PBT) giving the fabric sideways stretch, with 31 or more but not over 36 single yarns per cm dyed light beige in the warp and 14 or more but not over 18 single yarns per cm dyed light brown in the weft (provided for in subheading 5407.53.20)

This HTS code, 9902.12.97, falls under Chapter 99, which governs temporary legislation and modifications. Specifically, it details a highly specific type of textile fabric that is subject to temporary measures. The covered fabric is characterized by being composed of 85 percent or more by weight of textured polyester filaments, plain woven, and constructed from yarns of different colors. Key physical attributes include a weight of 96 g/m² or more but less than 170 g/m², and a width of 142.2 cm or more. A distinctive feature of this fabric is the presence of weft yarns made of polybutylene terephthalate (PBT), which impart sideways stretch. The precise yarn count and dye specifications are also critical for classification: 31 to 36 single yarns per centimeter in the warp dyed light beige, and 14 to 18 single yarns per centimeter in the weft dyed light brown.

As a leaf node within Chapter 99, this category does not have further subdivisions. Its specificity means it is designed to capture only the exact fabric described, distinguishing it from other textile products that might share some characteristics but lack the precise combination of material composition, weave, weight, width, stretch properties, and color/yarn specifications. The temporary nature of Chapter 99 classifications indicates that these specific trade measures are subject to change and are not permanent tariff treatments.
