6105.90.10.00 - Of wool or fine animal hair (438)

This HTS classification, 6105.90.10.00, pertains to knitted or crocheted shirts for men or boys that are specifically made of wool or fine animal hair. This category captures garments where the primary textile component, by weight, is derived from sheep's wool, lamb's wool, goat hair, rabbit hair, camel hair, or other similar fine animal fibers. Examples include pullovers, cardigans, and t-shirts crafted entirely or predominantly from these natural animal fibers.

Distinguishing this category from its siblings is crucial for accurate classification. Unlike 6105.90.40.00, which specifically enumerates shirts containing 70 percent or more by weight of silk or silk waste, this category excludes such silk-based garments. Similarly, it differs from the broader "Other" category (6105.90.80) which would encompass knitted or crocheted shirts of other textile materials not falling under the specified wool/fine animal hair or silk categories.

As this node represents a leaf category within the HTS, there are no further subcategories to introduce. Therefore, the focus for classification under 6105.90.10.00 remains on confirming that the garment is a knitted or crocheted men's or boys' shirt and that its predominant textile content is wool or fine animal hair, as defined by the Harmonized System.
