6206.90.00.20 - Subject to wool restraints (440)

This HTS classification, 6206.90.00.20, pertains to women's or girls' blouses, shirts, and shirt-blouses that are not knitted or crocheted and are specifically subject to wool restraints. These garments are generally manufactured from woven fabrics, excluding those made from cotton, man-made fibers, or other specific textile categories addressed by sibling codes. The defining characteristic for this subcategory is the presence of wool as a primary component, necessitating adherence to specific import limitations outlined by the referenced wool restraints.

Distinguishing this category from its siblings is crucial for accurate classification. HTS 6206.90.00.10 covers similar apparel but is subject to cotton restraints, while 6206.90.00.30 is specifically for garments under man-made fiber restraints. HTS 6206.90.00.40 encompasses all other women's or girls' blouses, shirts, and shirt-blouses of other textile materials not falling under the specific restraint categories. Therefore, classification under 6206.90.00.20 hinges on the material composition being predominantly wool and the garment being subject to those particular trade restrictions.

As a leaf node, this classification does not have further subcategories. Therefore, importers and customs professionals should focus on verifying the material content for wool and confirming that the garment is indeed subject to the specified wool restraints to ensure correct entry.
