Last updated: April 2026 dataCovering a notably broad range of components — from hydrojet marine propulsion parts (8412901000) and hydraulic cylinder parts (8412909005) to wind turbine blades imported under statistical note 2 (8412909070) and wind turbine hubs (8412909075) — this heading is one of the more complex parts provisions in Chapter 84. Mexico and India lead US imports, with China also a significant source; goods of Chinese origin across several lines here may be subject to Section 301 tariffs. The dedicated wind turbine blade and hub lines reflect the scale of US renewable-energy infrastructure investment and require careful attention to the applicable statistical note for correct filing.

Statistical Note 2 to Chapter 84 sets out specific reporting requirements for wind turbine blades entered under that line, distinguishing them from the general wind turbine blades and hubs line (8412909081). Importers must confirm which line applies based on whether the entry meets the note's criteria; misclassification can affect trade statistics reporting and potentially duty treatment. A licensed customs broker should review the note before filing.
The distinction follows the parent engine classification: parts specifically for hydraulic cylinders (linear acting) go to 8412909005, while parts for rotary or other non-linear hydraulic motors go to 8412909015. If a part is common to both types, general classification rules — including the essential character principle — apply, and a binding ruling from CBP may be advisable for high-volume shipments.
