5408.21.00.60 - Weighing more than 170 g/m² (618) 🖩

This HTS category, 5408.21.00.60, specifically classifies unbleached or bleached woven fabrics composed of artificial filament yarn that weigh **more than 170 grams per square meter (g/m²)**. These fabrics are derived from artificial filaments or strip and contain 85 percent or more by weight of such materials. The focus here is on heavier-weight woven fabrics, indicating a greater density or thicker yarn construction compared to lighter-weight alternatives.

The primary distinction of this subcategory lies in its weight specification. It is differentiated from its sibling, 5408.21.00.30, which covers the same types of woven fabrics but specifies a weight of **not more than 170 g/m²**. Therefore, when classifying unbleached or bleached woven fabrics of artificial filament yarn containing at least 85% artificial filament or strip, the decisive factor for placement within these two sibling categories is the material's weight per unit area.

As this classification is a leaf node, there are no further subdivisions. All goods falling under this category are considered to be at the most granular level of detail within the HTS for this specific type of fabric. Practical classification hinges on accurately determining the fabric's weight, ensuring it exceeds the 170 g/m² threshold. Examples might include heavier-duty artificial silk fabrics, upholstery materials, or industrial textiles where a more substantial construction is required.
