6106.90.25.30 - Subject to man-made fiber restraints (639) 🖩

This HTS classification covers knitted or crocheted blouses and shirts for women or girls that are specifically made from man-made fibers. These garments are subject to specific import restraints, indicated by the numerical code (639), which govern their entry into the country. This designation ensures compliance with quotas or other trade regulations established for textiles composed of synthetic or artificial fibers.

It is crucial to distinguish this category from its siblings. While all fall under the broader umbrella of women's or girls' knitted or crocheted blouses and shirts made from "other textile materials," this specific subcategory is exclusively for those manufactured from man-made fibers. This contrasts with sibling categories designated for cotton restraints (6106.90.25.10) or wool restraints (6106.90.25.20), and also differs from the residual "Other" category (6106.90.25.50) which would encompass knitted or crocheted blouses and shirts from other textile materials not specifically mentioned.

As this classification is a leaf node, there are no further subcategories to explore. Therefore, correct classification hinges on accurately identifying the garment's construction as knitted or crocheted, its intended user as women or girls, its style as a blouse or shirt, and, critically, its fiber content being exclusively man-made, while also being aware of the specific restraint requirements associated with code (639).
