HS Code 5103.10 – Wool and hair; noils of wool or of fine animal hair, including yarn waste, but excluding garnetted stock
HS code 5103.10 is the 6-digit subheading for wool and hair, noils of wool or of fine animal hair, including yarn waste, but excluding garnetted stock. It is used for wool noils, cashmere noils, alpaca noils, mohair noils and fine animal hair noils.
What HS 5103.10 covers
This code covers "noils" of wool or fine animal hair, which are the short fibers separated during the combing process, along with certain types of yarn waste. These are valuable byproducts of textile manufacturing, representing fibers that are too short for high-quality spinning but still possess useful properties. Exporters are typically textile mills and processing plants in countries with significant wool and fine animal hair industries, such as China, Italy, and India, where combing operations are prevalent. Importers are often manufacturers of non-woven materials, felts, insulation, or lower-grade yarns, seeking cost-effective fiber sources. Key aspects of this trade include the fiber composition (wool, cashmere, alpaca, etc.), cleanliness, and consistency of length. While not as valuable as virgin long fibers, noils are an important part of the circular economy within the textile industry, minimizing waste and providing raw material for alternative applications.

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).
