HS Code for Polyester artificial blend yarn

Polyester artificial blend yarn is classified under HS code 5509.51. This classification falls within Chapter 55, which covers man-made staple fibers. Heading 5509 specifically addresses yarn (other than sewing thread) made of synthetic staple fibers. The classification logic follows the rules of Section XI (Textiles), where blends are classified according to the material that predominates by weight. For this specific code, the yarn must be composed mainly of polyester staple fibers (synthetic) mixed with artificial staple fibers (such as viscose rayon, acetate, or modal). Furthermore, this code is reserved for yarn "not put up for retail sale," meaning it is intended for industrial use and typically arrives on large cones, cheeses, or beams for weaving or knitting processes.

Products Included

Common Misclassification

This code is often confused with 5509.21 (100% polyester staple yarn) or 5509.53 (polyester mixed with cotton). It is also frequently confused with 5402, which covers synthetic filament yarn. The key distinction is that 5509.51 must be made from staple fibers (discontinuous) rather than continuous filaments. If the yarn is packaged for retail sale (e.g., small balls for hand-knitting), it must be classified under 5511.
