4206.00.19.10 - Racquet strings

This HTS category, 4206.00.19.10, specifically covers racquet strings. These are the flexible cords used to string tennis, squash, badminton, and similar racquets. The classification is rooted in Chapter 42, which deals with articles made from various animal-derived materials, excluding silkworm gut. Within this chapter, Heading 4206 encompasses articles of gut (other than silkworm gut), goldbeater's skin, bladders, or tendons.

The distinction between 4206.00.19.10 and its sibling category, 4206.00.19.30 (also described as "Other"), lies in the specific product type. While both fall under the broader "Other" subcategory for articles of catgut, this particular code is reserved exclusively for racquet strings. The sibling category would likely encompass other, less common or unspecifically defined articles made from catgut that do not meet the precise definition of racquet strings.

As this is a leaf node, there are no further subcategories within this specific HTS code. Therefore, the classification hinges entirely on identifying the product as racquet strings made from catgut, as per the detailed description and the hierarchical placement within the HTS. The key criterion for classification under this code is the intended use and physical characteristics of the string as a component for stringing sports racquets.
