HS code for Pure combed wool yarn: 5107.10
Yarn, of combed wool, containing 85% or more by weight of wool, not put up for retail sale.
Classification of pure combed wool yarn under HS 5107.10
Pure combed wool yarn is classified under HS code 5107.10. This product falls under Chapter 51, which covers wool and animal hair. Heading 5107 is specifically reserved for yarn of combed wool, often referred to in the industry as worsted yarn. The combing process is a sophisticated mechanical step that follows carding. It involves passing the fibers through fine-toothed combs to remove short fibers (noils) and align the remaining long fibers in a strictly parallel arrangement. This results in a yarn that is significantly smoother, finer, and stronger than carded yarn. Subheading 5107.10 is applied when the yarn consists of 85% or more wool by weight. Like its carded counterpart, this code is intended for yarn that is not put up for retail sale, meaning it is destined for industrial looms or knitting machines. The high wool content and the combing process make this yarn a premium material for high-quality apparel, particularly tailored suits and fine knitwear.

Codes often confused with 5107.10
Common mistake. The most common misclassification is with HS code 5106.10, which covers carded wool yarn. The distinction lies entirely in the combing process. Another error is 5107.20, which is for combed wool yarn containing less than 85% wool by weight. If the yarn is packaged for retail sale (e.g., for hand knitting), it should be classified under 5109.10. Furthermore, yarn made from fine animal hair (like cashmere or mohair) that has been combed is classified under 5108.20, not 5107.10, even if the processing method is identical.

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).
