6105.90.80.10 - Subject to cotton restraints (338) 🖩

This classification covers men's or boys' shirts, knitted or crocheted, made from textile materials other than cotton, wool, or man-made fibers that are specifically subject to restraint. This includes garments primarily constructed from other natural fibers, blends not falling under the explicitly restrained categories, or novel textile materials. The key characteristic for this classification is the absence of specific quantitative import restraints applicable to cotton, wool, or certain man-made fibers for this particular item.

It is crucial to differentiate this category from its siblings. HTS code 6105.90.80.20 applies to shirts subject to wool restraints, while 6105.90.80.30 pertains to those under man-made fiber restraints. The "Other" category (6105.90.80.60) is for shirts of other textile materials that are not subject to *any* restraint. Therefore, this specific code (6105.90.80.10) is for shirts of "other textile materials" where a restraint *does* exist, but it is specifically for cotton.

As this is a leaf node in the HTS structure, there are no further subcategories to detail. Classification within this code is determined by the primary textile material of the shirt and whether it is subject to cotton restraints, as indicated by the descriptor (338). Practical classification will involve verifying the fiber content and consulting the relevant USITC restraint list to confirm the application of cotton restrictions.
