Artificial fibers — regenerated cellulosics such as viscose and modal — define the classification boundary here, distinguishing these knitted dresses from cotton, wool, and synthetic-fiber counterparts under Chapter 61. The US schedule subdivides the heading by wool content: dresses containing 23% or more wool (6104441000) carry a different duty treatment than those below that threshold, which are further split between women's (6104442010) and girls' (6104442020) sizes. Vietnam leads US supply, followed by China and Italy, making Section 301 exposure on Chinese-origin goods a routine compliance consideration for importers sourcing across multiple origins. Correct fiber identification — particularly distinguishing artificial from synthetic man-made fibers — is the most common classification dispute at entry.
