5407.10.00.10 - Of polyester, weighing not more than 170 g/m² (619)

This HTS classification covers woven fabrics specifically manufactured from high tenacity yarn of either nylon or other polyamides, or from polyesters. These are robust yarns designed for applications requiring exceptional strength and durability. The key defining characteristic of fabrics within this subheading is their weight, which must not exceed 170 grams per square meter. This weight threshold is crucial for differentiating these fabrics from others made from similar high tenacity yarns.

This category is distinguished from its sibling, 5407.10.00.90, by the specific weight limitation of not more than 170 g/m². The sibling category encompasses all other woven fabrics derived from high tenacity nylon, polyamide, or polyester yarns that *exceed* this weight threshold, or do not meet other specific criteria that might place them elsewhere. Therefore, the precise weighing of the fabric is the primary determinant in selecting between these two sibling subheadings.

As this is a leaf node within the HTS classification system, there are no further subcategories. Classification under 5407.10.00.10 is final for woven fabrics of high tenacity nylon, polyamide, or polyester yarns that meet the specified weight criteria. Examples of such fabrics could include those used in certain types of performance apparel, lightweight industrial textiles, or specialized outdoor gear where strength-to-weight ratio is paramount.
