4206.00.13.00 - If imported for use in the manufacture of sterile surgical sutures

This HTS category, 4206.00.13.00, specifically addresses articles made of animal gut, goldbeater's skin, bladders, or tendons that are intended for a very particular use: the manufacture of sterile surgical sutures. This precise application is the defining characteristic, distinguishing these materials from general articles of animal gut. The critical factor for classification under this subheading is the importer's declaration and verifiable intent for the goods to be processed into sterile surgical sutures.

In contrast to its sibling category, 4206.00.19, which covers "Other" articles of animal gut, goldbeater's skin, bladders, or tendons not meeting the specific criteria of this subheading, 4206.00.13.00 is narrowly defined. The "Other" category would encompass a broader range of products, such as non-surgical gut strings for musical instruments or other specialized uses of animal-derived materials. The key differentiator here is not simply the material itself, but its predetermined role in the production of medical supplies.

As this is a leaf node within the HTS structure, there are no further subcategories to explore. Classification under 4206.00.13.00 is definitive when the goods are confirmed to be destined for sterile surgical suture production. Importers should be prepared to provide documentation or evidence supporting this intended use to customs authorities, ensuring accurate classification and compliance with import regulations.
