5402.47 - Other, of polyesters:

HTS code 5402.47 falls under the broader category of "Other yarn, single, untwisted or with a twist not exceeding 50 turns/m," within synthetic filament yarn. This specific classification applies to single synthetic filament yarns composed entirely of polyesters, excluding those with high degrees of twist or those specifically designated as partially oriented. These yarns are not intended for retail sale and are therefore typically supplied in bulk for industrial or manufacturing purposes.

To distinguish 5402.47 from its siblings, it's crucial to note the material. It specifically covers polyester yarns, differentiating it from elastomeric yarns (5402.44), nylon or polyamide yarns (5402.45), and polypropylene yarns (5402.48). Unlike 5402.46.00.00, this category is not limited to partially oriented polyester yarns. The "Other" designation in the sibling category 5402.49 implies it covers synthetic filament yarns of other materials not otherwise specified.

The subcategories within 5402.47 further refine the classification based on specific physical characteristics of the polyester yarn. 5402.47.10 distinguishes yarns by their decitex measurement (between 75 and 80 decitex) and a precise filament count (24 filaments per yarn). Any other polyester single filament yarns fitting the general description of 5402.47 but not meeting these specific criteria will be classified under the residual category 5402.47.90.
