5407.71.00.60 - Weighing more than 170 g/m² (620)

This category, HTS Code 5407.71.00.60, specifically classifies woven fabrics composed of synthetic filament yarn that weigh more than 170 grams per square meter. These fabrics are derived from materials specified in heading 5404 and contain at least 85 percent by weight of synthetic filaments. The key distinguishing factor for this classification is the fabric's weight.

This classification differs from its sibling category, 5407.71.00.15, which covers similar woven fabrics of synthetic filament yarn but specifically those weighing *not more than* 170 grams per square meter. Therefore, the decisive criterion for placing a fabric within this HTS code, as opposed to its sibling, is its weight relative to the 170 g/m² threshold. Both categories fall under the broader umbrella of "Unbleached or bleached" woven fabrics containing 85 percent or more synthetic filaments.

As this is a leaf node within the HTS structure, there are no further subcategories to explore. Classification at this level is final, based on the material composition (at least 85% synthetic filament yarn), the nature of the weave, the processing state (unbleached or bleached), and critically, the weight of the fabric exceeding 170 grams per square meter. Examples of goods that might fall into this category include heavier weight synthetic textile materials used in industrial applications, upholstery, or durable apparel where a significant fabric weight is a primary characteristic.
