5007.90.60.30 - Subject to wool restraints (410)

This HTS category, 5007.90.60.30, specifically classifies woven fabrics of silk or silk waste that are subject to wool restraints. These restraints are typically quantitative limits imposed on the import of certain textile articles to manage trade flows and protect domestic industries. The presence of these restraints is a key defining characteristic for goods falling under this heading.

This classification is distinguished from its sibling category, 5007.90.60.90 ("Other"), by the specific imposition of wool restraints. While both fall under "Other woven fabrics" of silk, the "Other" sibling does not have this particular trade restriction applied. Therefore, the crucial factor in differentiating between these two categories is the presence or absence of specific import limitations related to wool content or origin, as indicated by the "wool restraints (410)" note.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Classification under 5007.90.60.30 is final once the criteria of being a woven fabric of silk or silk waste, and being subject to the specified wool restraints, are met. Importers must carefully review import regulations and the specific "410" note to accurately determine if their silk fabric shipments fall under this restricted category.
