9201.20.00.31 - Containing a case measuring 167.64 cm or more but less than 180.34 cm in length

This HTS classification pertains to grand pianos that are equipped with a case measuring at least 167.64 cm but less than 180.34 cm in length. These instruments fall under the broader category of keyboard stringed instruments, specifically identified as grand pianos due to their characteristic horizontal string arrangement and large soundboard. The classification hinges on the precise external dimensions of the instrument's case, serving as a key differentiator for customs purposes.

This specific subcategory distinguishes itself from its siblings based on the length of the piano case. For instance, pianos with cases measuring less than 152.40 cm (9201.20.00.11) or between 152.40 cm and 167.64 cm (9201.20.00.21) are classified separately. Similarly, pianos with larger cases, such as those measuring 180.34 cm or more but less than 195.58 cm (9201.20.00.41) or exceeding 195.58 cm (9201.20.00.51), are placed in distinct classifications. This granular approach ensures accurate tariff application based on the physical size of the grand piano.

As a leaf node in the HTS classification structure, this category does not have further subdivisions. Therefore, classification within this code is complete once the grand piano meets the specified case length criteria. Importers and exporters should ensure that the documented dimensions accurately reflect the external measurements of the piano's case to facilitate correct customs declarations and avoid potential discrepancies.
