Product classification
HS code for Yarn winder: 8445.40
Textile machinery, winding (including weft-winding) or reeling machines.
Classification of yarn winder under HS 8445.40
HS code 8445.40 is applied to yarn winding or reeling machines. These machines are essential components in the textile manufacturing process, used to transfer yarn from one package form to another, such as from a spinning bobbin to a cone, or for preparing weft yarn for weaving. Under the Harmonized System, heading 8445 covers machinery for the preparation of textile fibers and the production of yarn. Subheading 8445.40 specifically targets the winding and reeling functions. This classification includes automatic winding machines, which may incorporate yarn clearing and splicing technologies, as well as simpler manual reeling frames. The primary characteristic for classification here is the machine's role in package formation and yarn management without altering the physical twist or structure of the yarn itself, which differentiates it from spinning or twisting machinery. These machines are used across various sectors of the textile industry, handling everything from fine silk to heavy industrial yarns.

Codes often confused with 8445.40
Common mistake. The most common misclassification is with 8445.30 (twisting machines) or 8445.20 (spinning machines). While these machines are often located near each other in a factory, their mechanical functions are distinct. Additionally, winding machines that are integrated into a loom or knitting machine may sometimes be incorrectly classified with the main machine (8446 or 8447), but stand-alone winders must remain in 8445.40.
Top exporters and importers of HS 844540 (the code used for yarn winder), 2025

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).
