5407.61.99.35 - Weighing more than 170 g/m² (620) 🖩

This HTS classification covers dyed woven fabrics of synthetic filament yarn, specifically those containing 85 percent or more by weight of polyester filaments, and further refined to include non-textured polyester filaments. The defining characteristic of this subcategory is its weight: these fabrics weigh **more than 170 grams per square meter (g/m²)**. These are typically more substantial fabrics used in applications where durability and a heavier drape are required, such as certain types of upholstery, industrial textiles, or heavier apparel.

This category is distinguished from its sibling category by its weight specification. The sibling, which weighs "not more than 170 g/m²," represents lighter-weight fabrics. The distinction is critical for customs purposes, as weight is a primary determinant for classification within this section, often impacting duty rates and regulatory requirements. This focus on weight ensures that fabrics with different physical properties and end-uses are categorized appropriately.

As this node is a leaf node in the HTS structure, there are no further subdivisions. Therefore, the classification is finalized at this point based on the material composition (85% or more polyester filaments, non-textured), the dyeing process, and the weight exceeding 170 g/m². Importers and exporters should ensure their goods precisely meet these criteria to maintain accurate classification.
