6206.30.20.00 - Containing 36 percent or more by weight of flax fibers (341)

This HTS category, 6206.30.20.00, specifically covers women's or girls' blouses, shirts, and shirt-blouses that are not knitted or crocheted, and are primarily made of cotton. The defining characteristic of this classification is the significant cotton content, explicitly those containing 36 percent or more by weight of flax fibers, which falls under a specific sub-classification within the broader category of cotton apparel.

Within the "Of cotton" classification for women's or girls' blouses, shirts, and shirt-blouses, this specific code, 6206.30.20.00, is distinguished by its particular material composition. Its sibling category, 6206.30.30, titled "Other," would encompass cotton blouses, shirts, and shirt-blouses that do not meet the specific flax fiber percentage criteria outlined here, or are made of other cotton blends or constructions not specified elsewhere. Therefore, the presence of 36 percent or more flax fibers by weight is the key differentiator for goods classified under 6206.30.20.00.

As this is a leaf node within the HTS, there are no further subcategories to introduce. Classification under 6206.30.20.00 is final for women's or girls' non-knitted blouses, shirts, and shirt-blouses predominantly made of cotton and containing at least 36 percent flax fibers by weight. Importers and exporters should carefully verify the fiber content and garment type to ensure accurate classification, as misclassification can lead to duties and penalties.
