HS Code for Synthetic staple fiber yarn

HS code 5509.42 is assigned to multiple (folded) or cabled yarn that contains 85% or more by weight of synthetic staple fibers. This classification is part of Chapter 55, which covers man-made staple fibers and the yarns derived from them. Heading 5509 is specific to yarn (other than sewing thread) of synthetic staple fibers that is not put up for retail sale. The subheading 5509.42 is reserved for yarns made of "other" synthetic fibers—those not classified as polyester, acrylic, or modacrylic—that have been twisted together in a multiple or cabled construction. The 85% weight threshold is a critical legal requirement; if the synthetic content is lower, the yarn may be classified under different headings in Chapter 55 or Chapter 52/54 depending on the blend. Furthermore, the "not put up for retail sale" condition distinguishes industrial or bulk yarn from consumer-packaged products. This code is vital for industrial textile manufacturers who utilize specialized synthetic yarns for heavy-duty applications.

Common Misclassification

Common misclassifications include 5508.10, which is for sewing thread, and 5511.10, which is for yarn put up for retail sale. Additionally, if the yarn is made of continuous filaments rather than staple fibers, it would fall under heading 5402. Misidentifying the yarn construction (single vs. multiple) can also lead to using 5509.41 instead of 5509.42.
