6105.20.20 - Other

This category, HTS 6105.20.20, encompasses knitted or crocheted shirts for men and boys that are primarily composed of man-made fibers. It falls under the broader classification of men's or boys' shirts made from man-made fibers, excluding those with a significant wool or fine animal hair content.

The distinction from the sibling category, HTS 6105.20.10.00, is crucial. While both are knitted or crocheted shirts of man-made fibers, this category specifically excludes items containing 23 percent or more by weight of wool or fine animal hair. Therefore, if a shirt is predominantly man-made fibers but also contains a substantial portion of wool or fine animal hair, it would be classified under the sibling category.

This HTS code serves as a general heading for man-made fiber shirts for men and boys, with further subclassification to distinguish between men's and boys' specific garments. The subcategories "Men's" and "Boys'" allow for a more precise classification based on the intended wearer, reflecting the different sizing and design considerations for these demographics.
