5402.46.00.00 - Other, of polyesters, partially oriented

HTS code 5402.46.00.00 specifically classifies other synthetic filament yarns, not put up for retail sale, that are composed of polyesters and are in a partially oriented state. This designation applies to single yarns that are either untwisted or have a twist not exceeding 50 turns per meter. The "partially oriented" characteristic is a key defining feature, distinguishing these yarns from fully drawn or textured polyester yarns.

This category is differentiated from its siblings by the specific combination of material (polyester) and filament state (partially oriented). For instance, 5402.44.00 covers elastomeric yarns, while 5402.45.00 deals with yarns of nylon or other polyamides. Similarly, 5402.47.00 encompasses other types of polyester yarns that do not meet the partially oriented criteria, and 5402.48.00 addresses polypropylene yarns. The "Other" categories at the 5402.49 level capture remaining synthetic filament yarns not otherwise specified.

As a leaf node, HTS code 5402.46.00.00 represents the most granular classification for this particular type of polyester yarn. Classification within this code hinges on the yarn being of polyester, being in a partially oriented filament form, and not exceeding the specified twist rate. Examples of goods that would fall here include undrawn or semi-drawn polyester filament yarns used in downstream textile manufacturing processes, such as weaving or knitting, where further processing is required to achieve the final desired yarn properties.
