HS code for Polyester artificial blend yarn: 5509.51

Yarn, (not sewing thread), of polyester staple fibres, mixed mainly or solely with artificial staple fibres, not put up for retail sale.

Classification of polyester artificial blend yarn under HS 5509.51

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.

Codes often confused with 5509.51

Common mistake. 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.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
