5007.90 - Other fabrics:

HTS Code 5007.90 encompasses woven fabrics of silk or silk waste that do not fit into the more specific subheadings of 5007.10 or 5007.20.00. This category acts as a residual classification for silk fabrics, meaning it captures those that are primarily composed of silk or silk waste but do not meet the strict 85% or more by weight criteria for silk or silk waste outlined in other provisions, nor are they specifically fabrics of noil silk. Therefore, importers and exporters should examine the material composition and weaving structure to determine if a silk fabric falls under this heading.

The distinction between 5007.90 and its siblings is crucial for accurate classification. HTS code 5007.10 specifically covers fabrics made from noil silk, a coarser type of silk yarn. In contrast, HTS code 5007.20.00 is designated for other woven silk fabrics that contain a high proportion, specifically 85 percent or more by weight, of silk or silk waste other than noil silk. HTS 5007.90, therefore, serves as the catch-all for woven silk fabrics with a lower percentage of silk or silk waste, or those with a complex composition not exclusively dominated by silk.

To further refine the classification within HTS 5007.90, two subcategories exist. HTS 5007.90.30 is for woven fabrics containing 85 percent or more by weight of silk or silk waste, effectively covering those silk fabrics that may have minor components of other materials but are still predominantly silk or silk waste. HTS 5007.90.60, on the other hand, is for all other woven fabrics under the 5007.90 umbrella that do not meet the 85% threshold, allowing for a clear distinction between highly silk-dominant fabrics and those with a more varied composition.
