6205.90.40.30 - Subject to man-made fiber restraints (640)

This HTS classification covers men's or boys' shirts made from textile materials other than cotton, wool, or those subject to specific man-made fiber restraints. Specifically, this code applies to shirts that are not explicitly classified under cotton or wool restraints, and are also not subject to the other designated man-made fiber restraints (640) found within this subheading. Examples could include shirts made from silk, linen, ramie, or other non-specified man-made fibers that fall outside the more narrowly defined categories.

The primary distinction of this category lies in its residual nature for "other" textile materials that do not fit into the preceding sibling categories. While 6205.90.40.10 is for cotton-restrained shirts, and 6205.90.40.20 is for wool-restrained shirts, this classification (6205.90.40.30) is for those man-made fiber shirts not subject to the specific (640) restraint. It acts as a catch-all for items that are men's or boys' shirts but do not meet the material or restraint criteria of the other subheadings at this level.

As a leaf node within the HTS structure, there are no further subcategories to introduce. Classification at this level is dependent on the precise material composition of the shirt and whether it falls under any explicit trade restraints indicated by the parenthetical figures. Importers must carefully consider the fiber content and consult any applicable quota or restraint lists to ensure correct classification.
