9506.51.20.00 - Rackets, strung

This HTS category, 9506.51.20.00, specifically covers lawn tennis rackets that are supplied already strung. The defining characteristic for classification within this subheading is the presence of strings affixed to the racket frame, ready for immediate use in a game of lawn tennis. This includes rackets of various sizes and constructions, provided they are intended for this particular sport and are presented in a strung condition.

It is crucial to distinguish this subheading from its sibling category, 9506.51.40.00, which pertains to lawn tennis rackets that are not strung. The key differentiator is the inclusion of the stringing material in the product presented for customs clearance. Therefore, if a lawn tennis racket is imported without strings, it would fall under the "not strung" category, even if it is otherwise identical in frame construction and purpose.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Classification terminates at this level for strung lawn tennis rackets. Therefore, the focus for importers and customs officials is on confirming the specific item is a lawn tennis racket and that it is presented with its strings installed.
