5109.90.20.00 - Yarn of wool, colored (dyed or printed) and cut into uniform lengths of not over 8 cm (400)

This classification covers yarn of wool that has been colored, either through dyeing or printing. A key defining characteristic of this specific yarn is that it is cut into uniform lengths not exceeding 8 centimeters. This precise measurement is critical for accurate classification, distinguishing it from longer lengths or continuous skeins. The material focus is exclusively on wool, adhering to the scope of Chapter 51.

Within the broader category of "Yarn of wool or of fine animal hair, put up for retail sale," this node specifically addresses "Other" yarns that do not fall under more specific provisions. Its sibling category, also labeled "Other," would typically be reserved for yarns of fine animal hair or wool yarns that do not meet the specific criteria of this sub-classification. The uniform cutting and coloring are the primary differentiators.

As this is a leaf node, there are no further subcategories. Therefore, classification within this code is final based on the presence of wool yarn, its colored state (dyed or printed), and the uniform cutting into lengths of 8 cm or less. For example, a bundle of short, dyed wool fibers prepared for a specific craft or industrial use would fall here, provided they meet the length requirement.
