HS code for Carded wool yarn (bulk): 5106.10
Yarn, of carded wool, containing 85% or more by weight of wool, not put up for retail sale.
Classification of carded wool yarn (bulk) under HS 5106.10
The classification of bulk carded wool yarn under HS code 5106.10 is determined by three primary factors: the fiber type, the processing method, and the packaging format. Under Chapter 51, heading 51.06 is designated for yarn of carded wool that is not put up for retail sale. The subheading 5106.10 is specifically for yarn where the wool content is 85% or more by weight. This high wool content distinguishes it from blended yarns. The "carded" designation indicates that the wool fibers were processed using a carding machine to create a somewhat fuzzy, voluminous yarn, often referred to as "woolen yarn" in the industry. This is distinct from "combed" wool yarn (worsted yarn), which would fall under heading 51.07. Furthermore, the "not put up for retail sale" criteria means the yarn is typically wound on large bobbins, cones, or beams for industrial weaving or knitting machines. If the yarn were packaged in small balls or skeins with labels and weight limits for individual consumers, it would be reclassified under heading 51.09. Accurate classification requires a laboratory analysis of fiber weight to confirm the 85% threshold is met. This classification is governed by GRI 1 and GRI 6, ensuring that the product is identified first at the heading level and then at the subheading level based on its specific characteristics. The presence of minor amounts of other fibers (up to 15%) does not change this classification, provided the wool remains the dominant component by weight.

Codes often confused with 5106.10
Common mistake. The most frequent misclassification occurs with HS code 5107.10, which covers combed wool yarn. Combed yarn is smoother and stronger than carded yarn. Another common error is using 5106.20, which is only for yarns with less than 85% wool. Additionally, if the yarn is intended for retail sale, it must be moved to heading 51.09.

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).
