HS Code 5107.10 – Yarn; of combed wool, containing 85% or more by weight of wool, not put up for retail sale
HS code 5107.10 is the 6-digit subheading for yarn, of combed wool, containing 85% or more by weight of wool, not put up for retail sale. It is used for combed merino wool yarn, worsted wool yarn (high wool content), fine gauge wool yarn, knitting wool yarn (industrial) and weaving wool yarn (industrial).
What HS 5107.10 covers
This HS code identifies high-quality wool yarn, specifically made from combed wool, where wool constitutes 85% or more of its weight. The "combed" aspect signifies a process that removes short fibers and aligns the longer ones, resulting in a smoother, stronger, and more lustrous yarn, ideal for fine textiles. "Not put up for retail sale" means it's traded in bulk, typically on cones or bobbins, destined for industrial manufacturing rather than direct consumer purchase. Major importers are textile-producing nations with significant apparel and fabric industries, such as Italy, China, and Turkey, which transform this yarn into high-end garments, suits, and luxury fabrics. Exporters are often countries with strong wool processing capabilities, including Italy, Germany, and China, which have invested in advanced spinning technologies. Understanding the yarn count, twist, and fiber fineness is crucial for buyers, as these characteristics dictate the yarn's suitability for specific weaving or knitting applications. The global demand for natural fibers, especially high-quality wool, drives trade in this category.

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).
