5407.71.00 - Unbleached or bleached

This HTS category, 5407.71.00, specifically covers woven fabrics that are composed of synthetic filament yarn and contain 85% or more by weight of synthetic filaments. The defining characteristic of this classification is that these fabrics are presented in an **unbleached or bleached** state. This means they have not undergone dyeing, printing, or the use of yarns of different colors to impart coloration.

To distinguish this category from its siblings, it is crucial to note the absence of applied color. Sibling category 5407.72.00 covers similar woven fabrics that have been dyed. Category 5407.73 concerns fabrics woven from yarns of different colors, creating a patterned effect through the combination of distinct yarn hues. Finally, 5407.74.00 is for fabrics that have been printed with designs or patterns. Therefore, 5407.71.00 isolates fabrics in their natural, uncolored, or chemically lightened state.

The subcategories under 5407.71.00 further refine the classification based on the fabric's weight. These subdivisions, 5407.71.00.15 and 5407.71.00.60, differentiate between fabrics weighing not more than 170 g/m² and those weighing more than 170 g/m². This distinction is a common criterion in textile classifications and is important for determining applicable duties or trade regulations, as fabric density and weight can influence its end-use and manufacturing complexity.
