5402.32.30.00 - Single yarn (600)

This HTS classification, 5402.32.30.00, specifically covers single yarns made from nylon or other polyamides. These yarns must not be put up for retail sale and are defined by their specific decitex measurement: they must measure more than 500 decitex per single yarn. The "textured yarn" designation indicates that the yarn has undergone a process to increase its bulk, loft, or stretch, deviating from a smooth filament structure. This category is distinct from other yarns within HTS heading 5402 due to its material (nylon/polyamides), its construction (single yarn), its preparation (not for retail sale), its decitex range (over 500), and its textured characteristic.

Within the broader category of textured yarns of nylon or other polyamides exceeding 500 decitex, this specific code differentiates itself from its sibling category, 5402.32.60.00. The key distinction lies in the construction: 5402.32.30.00 pertains to *single* yarns, meaning a single strand of filament. In contrast, its sibling covers *multiple (folded) or cabled* yarns, which are formed by twisting two or more single yarns together. Therefore, the number of individual filaments twisted together is the crucial factor in distinguishing between these two closely related classifications.

As this classification represents a leaf node in the HTS, there are no further subcategories to introduce. Classification at this level is final based on the criteria of material, construction (single yarn), preparation (not for retail sale), decitex measurement (over 500), and the textured characteristic. Importers and exporters must ensure that the goods precisely meet all these requirements to apply this code accurately, avoiding misclassification with other types of filament yarns or yarns with different construction or decitex values.
