Overview

This HTS category, 5508.10.00.00, specifically covers sewing thread manufactured from synthetic staple fibers. Synthetic staple fibers are man-made fibers that are cut into short lengths, resembling natural fibers like cotton or wool. Examples of synthetic staple fibers include polyester, nylon, acrylic, and polypropylene. This classification applies to sewing thread made from these materials, regardless of whether it is presented in retail packaging or in bulk for industrial use.

It is crucial to distinguish this category from its sibling, 5508.20.00.00, which covers sewing thread made from artificial staple fibers. Artificial staple fibers are also man-made but are derived from natural raw materials like cellulose (e.g., rayon, modal, lyocell). The primary differentiator for classification under 5508.10.00.00 is therefore the material composition: exclusively synthetic staple fibers.

As this is a leaf node within the HTS structure, there are no further subcategories. The classification is determined solely by the material type of the staple fibers used in the sewing thread. Therefore, if a sewing thread is composed of any synthetic staple fiber, it falls under this heading, provided it is not primarily made of yarn or thread of man-made filament.
