5407.51.00.60 - Weighing more than 170 g/m² (620)

This HTS classification covers woven fabrics manufactured from synthetic filament yarns, specifically those where the warp and weft are predominantly comprised of textured polyester filaments, constituting 85% or more of the fabric's weight. These fabrics are characterized by a specific weight threshold, falling into the category of those weighing *more than* 170 grams per square meter. This weight specification is a critical determinant for classification within this subcategory.

The primary distinction for this category lies in its weight. It is separated from its sibling category, which covers fabrics of the same material composition (85% or more textured polyester filaments) but weighing *not more than* 170 grams per square meter. Therefore, the precise grammage of the woven fabric is the key differentiating factor between these two closely related classifications.

As this node represents a leaf node within the HTS structure, there are no further subcategories. Classification under HTS 5407.51.00.60 is therefore finalized once it is determined that the fabric meets the criteria of being woven from synthetic filament yarn (including materials of heading 5404), contains 85% or more by weight of textured polyester filaments, is unbleached or bleached, and weighs more than 170 g/m². Examples of such fabrics might include durable upholstery materials, heavy-duty outdoor textiles, or certain technical fabrics where a higher weight is indicative of specific performance properties.
