9201.10.00.21 - Containing a case measuring 111.76 cm or more but less than 121.92 cm in height

This HTS classification covers upright pianos characterized by the dimensions of their cases. Specifically, it applies to upright pianos where the height of the case measures 111.76 cm or more but strictly less than 121.92 cm. This measurement is a crucial determinant for distinguishing pianos within the broader category of upright instruments, ensuring accurate tariff application based on physical attributes.

Within the "Upright pianos" heading, this specific subcategory is distinguished from its siblings by its defined height range. For example, it differs from 9201.10.00.11 which covers pianos with cases measuring less than 111.76 cm in height, and from 9201.10.00.31 and 9201.10.00.41 which encompass pianos with cases measuring 121.92 cm or greater in height. The precise measurement of the piano's case is therefore the key differentiator.

As this classification node is a leaf node, there are no further subcategories. This means that once a piano meets the criteria for case height between 111.76 cm and 121.92 cm, it is definitively classified under this specific HTS code, provided it also meets the broader definitions of an upright piano. Classification decisions at this level are therefore final within the hierarchy.
