5402.47.90.40 - Multifilament, with twist of 5 turns or more per meter (606)

This HTS classification, 5402.47.90.40, specifically identifies multifilament synthetic yarn, excluding sewing thread and monofilaments, that is not packaged for retail sale. The defining characteristic of this category is its twist level: the yarn must have a twist of 5 turns or more per meter, but not exceed the twist specified for other categories. These yarns are typically produced from polyester and are intended for further industrial processing, such as weaving or knitting into fabrics.

This category is distinguished from its sibling, 5402.47.90.20, primarily by the degree of twist. While the sibling category covers untwisted or lightly twisted multifilament yarns (less than 5 turns per meter), this classification applies to those with a more significant twist (5 turns or more per meter). This difference in twist can impact the yarn's strength, appearance, and suitability for different manufacturing processes.

As a leaf node, this classification does not have further subdivisions. Therefore, the focus for classification within this sub-heading is on confirming that the yarn is indeed multifilament, composed of polyester, possesses a twist of 5 or more turns per meter, and is not put up for retail sale. For practical classification, visual inspection of the yarn's construction and, if necessary, twist testing are the primary methods to ensure accurate entry.
