HS code for Artificial blend yarn: 5510.90

Yarn, (not sewing thread), of artificial staple fibres, mixed mainly or solely with fibres (other than wool, fine animal hair or cotton), not put up for retail sale.

Classification of artificial blend yarn under HS 5510.90

HS code 551090 is designated for yarn, excluding sewing thread, composed of artificial staple fibres. The defining characteristic for classification under this code is that the artificial staple fibres are mixed mainly or solely with other fibres, specifically excluding wool, fine animal hair, or cotton. Furthermore, the yarn must not be put up for retail sale. This classification ensures that yarns with specific blend compositions, where the natural fibre component is neither wool, fine animal hair, nor cotton, are accurately categorized. The "not put up for retail sale" criterion typically refers to bulk packaging, such as cones or bobbins, intended for industrial use in textile manufacturing.

Codes often confused with 5510.90

Common mistake. Common misclassifications often arise from the specific blend composition. HS code 551030 covers yarn of artificial staple fibres mixed mainly or solely with cotton. If the blend contains cotton, it should be classified under 551030, not 551090. Similarly, HS code 551020 is for yarns mixed mainly or solely with wool or fine animal hair. If these fibres are present, 551020 is the correct classification. Additionally, yarns consisting of 85% or more by weight of artificial staple fibres, not blended with other fibres (or only minor amounts), would fall under codes like 551011 or 551012, depending on their specific composition and whether they are put up for retail sale. The "not put up for retail sale" aspect is also critical; if the yarn is packaged for retail, other subheadings within Chapter 55 may apply.

Cambodia did not report 2025 data, and its estimate from partner records misses its trade with other countries that did not report: in 2024 that was 65% of its imports here ($25M, CEPII BACI), so it may also belong among the top importers.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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).
