HS Code 5510.11 – Yarn; (not sewing thread), single, of artificial staple fibres, containing 85% or more by weight of artificial staple fibres, not put up for retail sale
HS code 5510.11 is the 6-digit subheading for yarn, (not sewing thread), single, of artificial staple fibres, containing 85% or more by weight of artificial staple fibres, not put up for retail sale. It is used for single viscose rayon yarn, single modal yarn, single lyocell yarn, single acetate yarn and single cupro yarn.
What HS 5510.11 covers
This HS code covers single yarns, not sewing thread, composed of 85% or more by weight of artificial staple fibres, and not prepared for retail sale. Artificial staple fibres, such as viscose rayon, modal, lyocell, or acetate, are regenerated cellulosic fibres known for their softness, drape, breathability, and excellent dyeability. These yarns are crucial raw materials for textile manufacturers producing fabrics for apparel (e.g., dresses, blouses), home furnishings, and non-woven applications. Importers are typically textile mills seeking sustainable or luxurious alternatives to natural fibers, while exporters are major producers of artificial fibers and yarn spinners. The trade is influenced by fashion trends, environmental considerations, and the demand for comfortable, skin-friendly textiles, particularly in the sustainable fashion movement.

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).
