Product classification
HS code for Wool noils: 5103.10
Wool and hair, noils of wool or of fine animal hair, including yarn waste, but excluding garnetted stock.
Classification of wool noils under HS 5103.10
Wool noils are classified under HS code 5103.10 as a primary byproduct of the wool combing process. In the production of worsted wool, the combing machine separates long fibers (tops) from the short, curly fibers known as noils. This code also encompasses yarn waste, which includes broken or tangled yarns generated during spinning or weaving operations. The classification is strictly for wool or fine animal hair and excludes garnetted stock, which is fiber recovered by mechanically tearing up rags or yarn scraps. For a product to remain under 5103.10, it must not have been further processed into a state ready for spinning. If the waste has been carded or combed beyond the initial byproduct stage, it may be reclassified under heading 5105. This code is vital for the global textile recycling trade, as it distinguishes between raw processing waste and recovered secondary fibers.

Codes often confused with 5103.10
Common mistake. Wool noils are often confused with 5103.20, which covers other types of wool waste like burr waste or carding waste. They are also frequently misclassified as 5104.00 (garnetted stock), which involves a different recovery process from finished textiles. If the noils have been carded or combed for spinning, 5105.10 is the correct code.

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).
