5109.90 - Other:

This category, HTS Code 5109.90, encompasses yarns of wool or fine animal hair that are prepared for sale to the end consumer, but do not meet the specific criteria of the sibling category, 5109.10. Specifically, it covers yarns containing less than 85 percent by weight of wool or of fine animal hair. The "other" designation signifies that these yarns may be blended with other fibers, such as synthetic or vegetable fibers, while still retaining wool or fine animal hair as a significant component.

The primary distinction between this category and its sibling, 5109.10, lies in the quantitative composition. While 5109.10 exclusively deals with yarns where wool or fine animal hair constitutes 85 percent or more of the weight, 5109.90 includes those where this percentage is lower, allowing for a greater proportion of other materials. This difference is crucial for customs valuation and duty assessment, as the presence and percentage of different fiber types directly impact the classification and applicable tariff rates.

Within this broad "other" category, further subdivisions exist to refine classification based on specific processing or presentation. The subcategory 5109.90.20.00, for instance, targets yarns of wool that have been colored through dyeing or printing and are further processed by being cut into uniform lengths not exceeding 8 cm. This specificity allows for precise identification of highly processed yarns tailored for particular crafting or manufacturing purposes, ensuring accurate tariff application for these specialized products.
