6106.90.30.20 - Subject to wool restraints (438)

This HTS classification covers knitted or crocheted blouses and shirts for women or girls, made from textile materials other than cotton, man-made fibers, or those specifically covered by wool restraints. The key differentiator for this category is its exclusion of articles subject to specific fiber-based quantitative restraints.

To accurately classify goods within this section, it is crucial to differentiate between sibling categories based on applicable restraints. While 6106.90.30.10 pertains to items subject to cotton restraints, and 6106.90.30.30 relates to those under man-made fiber restraints, this particular classification, 6106.90.30.20, is designated for garments that fall under wool restraints. The sibling category 6106.90.30.40 serves as a residual category for all other "other" knitted or crocheted blouses and shirts not specifically addressed by the preceding sub-classifications.

As a leaf node in the HTS classification system, 6106.90.30.20 does not have further subcategories. Therefore, the classification of goods under this code relies on a thorough understanding of the definition of "wool restraints" and the specific materials used in the construction of the knitted or crocheted blouses and shirts, ensuring they do not fall under the other specifically enumerated restraint categories at this level.
