6206.10.00.20 - Subject to wool restraints (440)

This HTS classification, 6206.10.00.20, specifically covers women's or girls' blouses, shirts, and shirt-blouses that are made of silk or silk waste. These garments are tailored and not knitted or crocheted, falling under the broader category of apparel and clothing accessories. The "Subject to wool restraints (440)" designation indicates that the importation of these silk items is subject to specific quantitative limitations, often referred to as quotas, managed by designated authorities, which are identified by the reference number (440).

Distinguishing this category from its siblings, 6206.10.00.10 covers similar garments but is subject to cotton restraints, and 6206.10.00.30 is subject to man-made fiber restraints. Therefore, the primary differentiator for this particular subcategory is the material content (silk or silk waste) and the corresponding specific trade restrictions applied to it. The "Other" sibling category would encompass women's or girls' blouses and shirts of silk or silk waste that are not subject to the specific wool restraints.

As this is a leaf node in the HTS classification structure, there are no further subcategories. Classification under 6206.10.00.20 is therefore definitive for women's or girls' blouses, shirts, and shirt-blouses of silk or silk waste, provided they are subject to the specified wool restraints (440). Importers should ensure accurate documentation to demonstrate compliance with these particular trade regulations.
