5403.33.00.20 - Monofilament; multifilament, untwisted or with twist of less than 5 turns per meter

This HTS classification covers artificial monofilament yarn, as well as multifilament artificial yarn that is either untwisted or has a twist of less than 5 turns per meter. These yarns are specifically of cellulose acetate and are not presented for retail sale. The key characteristic is the low twist (or no twist) in multifilament yarns, distinguishing them from yarns with a higher degree of twist.

This category is distinct from its sibling, 5403.33.00.40, which covers multifilament artificial yarns of cellulose acetate with a twist of 5 turns or more per meter. The presence or absence of this specific twist level is the defining factor for classification between these two codes.

As this is a leaf node within the HTS structure, there are no further subcategories. Therefore, classification is solely determined by the material (cellulose acetate), the form (monofilament or multifilament), and the degree of twist for multifilament yarns. Examples of end-uses might include industrial textiles, certain types of filtration media, or components in technical fabrics where low twist is a required property.
