9902.15.52 - High pressure fuel pumps, each incorporating a default open or closed solenoid valve, certified by the importer to be used in regulating the fuel supply into the fuel rail, designed for use in gasoline direct injection (GDI) spark-ignition internal combustion piston engines (provided for in subheading 8413.30.90); the foregoing other than used goods

This HTS classification, 9902.15.52, specifically covers high-pressure fuel pumps designed for use in gasoline direct injection (GDI) spark-ignition internal combustion piston engines. These pumps are characterized by their incorporation of a default open or closed solenoid valve and require certification by the importer confirming their intended application in regulating fuel supply to the fuel rail. Crucially, this classification is limited to new, unused goods; used fuel pumps would fall under different tariff provisions.

Given that this node is within Chapter 99, a section dedicated to temporary legislation and special provisions, it is distinct from the primary product classifications found in earlier chapters. Unlike the sibling categories, which generally cover live animals (e.g., Chapters 01), this provision addresses a specific component for automotive engines. Its purpose is to manage the import of these specialized fuel pumps, likely due to specific trade agreements, temporary restrictions, or other policy measures implemented under Section XXII of the Agricultural Adjustment Act or similar trade legislation.

As a leaf node within the HTS database, HTS 9902.15.52 does not have further subdivisions. Therefore, the classification relies entirely on meeting the detailed description provided. Importers must ensure that the fuel pumps they are importing precisely match the criteria of being high-pressure, GDI-compatible, featuring the specified solenoid valve, and intended for fuel rail regulation. Any deviation from these specific requirements, such as pumps for different engine types or those that are not new, would necessitate classification under a different HTS code, likely within Chapter 84 which covers machinery and mechanical appliances, specifically subheading 8413.30.90 as referenced in the description for the underlying product.
