6203.19.90 - Other

This classification, HTS 6203.19.90, falls under men's or boys' suits made from textile materials other than cotton or silk. Specifically, it captures suits constructed from a broad range of textile fibers that do not meet the criteria for cotton or silk-based suits, nor are they categorized under specific artificial fiber compositions explicitly listed as siblings. The defining characteristic for inclusion here is the absence of these primary material classifications.

Distinguishing this category from its siblings is crucial for accurate classification. HTS 6203.19.10 specifically addresses suits of cotton, while other sibling entries (not fully detailed here but implied) would cover suits made predominantly of specific artificial fibers. HTS 6203.19.50.00, for instance, is reserved for suits with a high silk content. Therefore, HTS 6203.19.90 acts as a residual category for suits of other textile materials, such as those primarily composed of wool, linen, or blends where no single fiber type meets the criteria for a more specific classification.

Within this "Other" category, further subdivisions exist to address specific import regulations and trade restraints. The subcategories differentiate based on whether the suits are subject to restraints related to wool, man-made fibers, or if they fall under a general "Other" classification after accounting for these specific restraints. These distinctions are vital for compliance with quotas and other trade control measures that may be applied to textiles based on their fiber content and origin.
