4206.00.19 - Other

This HTS category, 4206.00.19, encompasses articles made from animal gut (excluding silkworm gut), goldbeater's skin, bladders, or tendons, specifically those not classified under the "of catgut" provision. This residual category is intended for items that, while manufactured from these animal-derived materials, do not fit into the more specific subheadings.

The primary distinction for this classification lies in its exclusion of articles made of catgut. While both fall under the broader scope of Chapter 42, this category specifically addresses items manufactured from other animal connective tissues, membranes, or organs, such as bladders or tendons, when they are not specifically designated as catgut products.

Within this category, further subdivisions exist to refine classification. The subcategory 4206.00.19.10 pertains to racquet strings, a common application of certain animal gut materials. The remaining items, not fitting the specific racquet string designation, are captured under the residual subheading 4206.00.19.30, labeled as "Other." This hierarchical structure ensures precise classification based on the specific end-use and material form.
