5407.61.11.00 - Wholly of polyester, of single yarns measuring not less than 75 decitex but not more than 80 decitex, having 24 filaments per yarn and with a twist of 900 or more turns per meter (619) 🖩

This HTS classification, 5407.61.11.00, specifically covers dyed woven fabrics that are wholly composed of polyester filament yarns. A key defining characteristic is that these yarns must meet precise specifications: they must measure between 75 and 80 decitex, contain exactly 24 filaments per yarn, and possess a twist of 900 or more turns per meter. Furthermore, these fabrics are distinguished by their relatively narrow width, being less than 77 cm in width or less than 77 cm between selvages. The thread count also plays a crucial role, requiring over 69 threads per cm in the warp and over 31 threads per cm in the filling, with an upper limit of 142 threads per cm in the warp and 71 threads per cm in the filling.

This specific subcategory differentiates itself from its sibling, 5407.61.19.00 ("Other"), by its highly restrictive specifications regarding yarn characteristics, twist, and precise thread count within a defined width. While both fall under the broader category of dyed, non-textured polyester filament woven fabrics containing 85 percent or more polyester by weight, 5407.61.11.00 is for those that meet all the enumerated technical yarn and fabric construction requirements. The "Other" category would encompass dyed woven fabrics of polyester meeting the general criteria but falling outside these precise yarn and thread count parameters, or those with different construction elements not specified here.

As this classification represents a leaf node within the HTS, there are no further subcategories. This means that any woven fabric of polyester meeting all the outlined yarn characteristics, twist, thread count, and width limitations will fall directly under this code. The classification hinges entirely on the precise adherence to the physical and technical specifications provided in the description, without further subdivision based on end-use or other secondary characteristics.
