6205.90.30 - Other

This HTS category, 6205.90.30, encompasses men's or boys' shirts not knitted or crocheted, specifically those manufactured from textile materials other than cotton, wool, or those containing 70 percent or more by weight of silk or silk waste. Therefore, this classification applies to shirts made from blended fabrics where silk or silk waste is present but does not meet the 70% threshold for the sibling category, or shirts made from other non-specified textile materials.

The key differentiator from its sibling category, 6205.90.10.00, lies in the material composition. While 6205.90.10.00 is exclusively for shirts containing 70 percent or more by weight of silk or silk waste, this category 6205.90.30 captures a broader range of "other" textile materials, allowing for shirts with silk or other fibers in varying proportions, as long as they don't fit the precise definition of the silk-dominant sibling.

Further subdivision within this category is based on specific trade restraints. The subcategories (6205.90.30.10, 6205.90.30.20, 6205.90.30.30, and 6205.90.30.50) distinguish shirts based on whether they are subject to cotton, wool, man-made fiber restraints, or fall under a general "other" classification for remaining items. This allows for precise tracking and management of imported goods based on international trade agreements and quotas.
