5407.81.00.40 - Satin weave or twill weave (628)

This HTS category, 5407.81.00.40, specifically classifies unbleached or bleached woven fabrics composed of synthetic filament yarn where the synthetic filament content by weight is less than 85 percent, and the remaining material is mixed mainly or solely with cotton. The defining characteristic of this subcategory is its weave structure, limited to satin weave or twill weave. These weaves are recognized by their distinct surface appearance and interlacing patterns, with satin weaves having a smooth, lustrous surface due to long floats, and twill weaves exhibiting diagonal parallel ribs.

This classification is distinguished from its sibling categories by the specific weave type. For instance, 5407.81.00.10 covers poplin or broadcloth weaves, which have a simpler plain weave structure. Similarly, 5407.81.00.20 pertains to sheeting, typically a plain weave fabric known for its use in bedding, and 5407.81.00.30 refers to printcloth, often a plain weave fabric suitable for printing. The residual sibling category, 5407.81.00.90, encompasses all other unbleached or bleached woven fabrics meeting the material criteria but not falling into the specific weave types designated by the other subcategories.

As this node is a leaf node within the HTS, it does not have further subcategories. Therefore, classification within 5407.81.00.40 is determined by the combination of the fabric's unbleached or bleached state, its composition (less than 85% synthetic filament yarn mixed mainly or solely with cotton), and the presence of a satin or twill weave. Examples of goods falling here would include certain types of unbleached cotton-synthetic blends in satin weave used for linings or interlinings, or bleached synthetic-cotton twill fabrics intended for specific apparel or upholstery applications where the less than 85% synthetic filament requirement is met.
