5408.33.30.00 - Containing 30 percent or more by weight of silk or silk waste, valued over $33 per kg (618)

This HTS classification, 5408.33.30.00, specifically covers woven fabrics of artificial filament yarn that are composed of 30 percent or more by weight of silk or silk waste, and which have a value exceeding $33 per kilogram. These fabrics are distinct from other categories within woven fabrics of artificial filament yarn due to their significant silk content and higher value threshold, placing them in a premium segment. The "Other" designation at this level indicates that it does not fall under more specific subdivisions based on thread count or exact percentage of man-made filaments as seen in sibling categories.

This classification differentiates itself from sibling category 5408.33.15.00, which focuses on fabrics with a very high percentage of man-made filaments (85% or more) and specific thread count ranges in both warp and filling. In contrast, 5408.33.30.00 prioritizes a substantial silk presence, irrespective of the man-made filament content beyond the initial requirement of being a woven fabric of artificial filament yarn, and is defined by its value per kilogram rather than precise thread density. The remaining sibling, 5408.33.90, serves as a catch-all for other woven fabrics of yarns of different colors that do not meet the specific criteria of 5408.33.15.00 or 5408.33.30.00.

As this is a leaf node in the HTS structure, there are no further subcategories. Classification under 5408.33.30.00 is final for eligible fabrics meeting both the material composition (30% or more silk/silk waste) and the value threshold (over $33/kg) requirements, within the broader scope of woven fabrics of artificial filament yarn of differing colored yarns. Examples of goods that would fall here include luxury scarves, high-end upholstery, or apparel linings where the blend of artificial filament and silk creates a unique texture and drape, and the retail or production cost justifies the higher valuation.
