9902.15.51 - New fuel pumps for compression-ignition engines, other than fuel-injection pumps, such pumps measuring 2 cm or more but not over 163 cm in length, 2 cm or more but less than 127 cm in width and 2 cm or more but less than 95 cm in height (provided for in subheading 8413.30.90)

This HTS category, 9902.15.51, specifically addresses new fuel pumps designed for compression-ignition engines, with the exclusion of fuel-injection pumps. The key classification criteria for this subheading are the physical dimensions of the pump. Specifically, the pump must measure 2 cm or more but not exceed 163 cm in length, be 2 cm or more but less than 127 cm in width, and 2 cm or more but less than 95 cm in height. These pumps are provided for under the more general heading of 8413.30.90, indicating their primary function as liquid pumps.

Unlike the broader categories of live animals or agricultural products found at the root level of the HTS, this category pertains to manufactured industrial components. Its specificity lies in its focus on a particular type of engine component with defined dimensional constraints, distinguishing it from other mechanical pumps or engine parts that might fall under different HTS headings.

As a leaf node within the HTS database, this category does not have further subcategories. Therefore, the classification is definitive based on the criteria outlined in the description: the item must be a new fuel pump for a compression-ignition engine, not a fuel-injection pump, and must fall within the specified length, width, and height parameters. Importers should carefully measure their goods to ensure they meet all these dimensional requirements for accurate classification.
