5403.31.00.20 - Monofilament; multifilament, untwisted or with twist of less than 5 turns per meter 🖩

This HTS category, 5403.31.00.20, specifically covers artificial filament yarn made from viscose rayon. The yarn must be either monofilament or multifilament that is untwisted or has a twist of less than 5 turns per meter. This classification is reserved for such yarns when they are not intended for retail sale, and are not sewing thread. The key defining characteristic here is the low twist level, essential for differentiating it from other multifilament rayon yarns.

This category distinguishes itself from its sibling, 5403.31.00.40, primarily by the degree of twist. While this category includes yarns with a twist of less than 5 turns per meter, the sibling category encompasses multifilament rayon yarns with a twist of 5 turns or more per meter. This difference in twist is a crucial physical characteristic for accurate classification, indicating distinct manufacturing processes and potential end-uses.

As this is a leaf node within the HTS, there are no further subcategories. Therefore, the focus remains on ensuring that goods meet all the criteria: being artificial filament yarn of viscose rayon, presented as monofilament or low-twist multifilament, and not put up for retail sale. Examples of products that would fall here include raw rayon filament yarn used in the manufacturing of textiles, industrial fabrics, or other specialized applications where a low degree of twist is required during the production process.
