6205.90.30.30 - Subject to man-made fiber restraints (640)

This HTS classification, 6205.90.30.30, specifically covers men's or boys' shirts made from textile materials that are not knitted or crocheted, falling under the broader category of "other textile materials" and then further specified as "of silk or silk waste." The key defining characteristic for this particular subclassification is that these silk or silk waste shirts are subject to man-made fiber restraints, as indicated by the reference (640). This means that while the primary material might be silk or silk waste, the presence and quantity of certain man-made fibers within the garment trigger specific import limitations or quotas.

To distinguish this category from its siblings, it is crucial to note the specific restraints applicable. Unlike shirts classified under 6205.90.30.10 (subject to cotton restraints) or 6205.90.30.20 (subject to wool restraints), this subcategory applies when man-made fibers, not cotton or wool, are the limiting factor for importation. The sibling category 6205.90.30.50, designated as "Other," would encompass silk or silk waste shirts that do not fall under any of the specified restraint categories.

As this classification represents a leaf node within the HTS structure, there are no further subcategories. Therefore, classification at this level is dependent on accurately identifying the garment as a men's or boys' shirt, not knitted or crocheted, composed of silk or silk waste, and critically, whether its composition triggers the man-made fiber restraints indicated. Importers must consult the relevant restraint details referenced by (640) to ensure compliance with specific import limitations.
