HS code for Combed wool yarn (bulk): 5107.10
Yarn, of combed wool, containing 85% or more by weight of wool, not put up for retail sale.
Classification of combed wool yarn (bulk) under HS 5107.10
HS code 510710 is the specific designation for yarn made of combed wool that contains 85% or more by weight of wool. This classification is found within Chapter 51, which governs wool and animal hair products. The primary technical requirement for this code is the high wool content and the application of the combing process. Combing is a secondary mechanical process after carding that straightens the fibers and removes impurities and short staples, producing a high-quality, fine yarn used in premium worsted fabrics. The "not put up for retail sale" designation indicates that the product is intended for industrial weaving or knitting operations rather than for individual consumer use. Classification requires precise laboratory testing of the fiber weight to ensure the 85% threshold is met or exceeded. This code is essential for the international trade of high-end textile raw materials, as combed wool yarn is the foundation for worsted suitings and fine knitwear. The distinction between carded and combed wool is vital because combed yarn is generally more expensive and subject to different trade regulations and quality standards than its carded counterparts.

Codes often confused with 5107.10
Common mistake. The most common misclassification occurs with HS code 510610, which applies to carded wool yarn with high wool content. While both are wool, the mechanical preparation (carding vs. combing) dictates the heading. It is also frequently confused with 510720 when the wool content drops below the 85% threshold. Furthermore, if the yarn is packaged for retail sale (e.g., for hand-knitting), it must be classified under heading 5109.

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).
