Overview
HTS Code 5402 encompasses synthetic filament yarns that are not intended for retail sale. This broad category includes yarns made from man-made fibers, such as nylon, polyester, and acrylic, which are typically supplied in large spools or skeins for industrial or manufacturing purposes. Crucially, this code also covers synthetic monofilament yarns with a decitex of less than 67, which are characterized by their single, continuous strand and fine diameter. It is important to distinguish this category from sewing thread (which falls under Chapter 63) and from natural filament yarns (found in Chapter 50).
The primary distinction of 5402 lies in its focus on bulk, unbranded synthetic filaments. Unlike sewing thread, these yarns are not pre-packaged with needles or designed for immediate use in household sewing. Furthermore, it excludes yarns derived from natural sources like silk, which are classified under Chapter 50. The "not put up for retail sale" criterion is key, indicating that the packaging and presentation are geared towards commercial users rather than individual consumers.
Within HTS 5402, further subdivisions are made based on the material and construction of the yarn. These include high-tenacity yarns of nylon or polyester, which are engineered for superior strength and used in applications like tire cords and industrial fabrics. Other subcategories differentiate yarns based on their twist, distinguishing between single untwisted or lightly twisted yarns, single yarns with a more significant twist, and multiple or cabled yarns formed by combining several strands. This detailed breakdown allows for precise classification based on the physical characteristics and intended industrial application of the synthetic filament yarn.
