US maintains anti-dumping duties on Chinese vertical shaft engines
The U.S. Department of Commerce has determined that revoking the anti-dumping duty order on certain large vertical shaft engines (225cc–999cc) and parts from China would likely lead to continued or renewed dumping. Commerce conducted an expedited first sunset review and decided to keep the existing duties in place. This affects importers of these engines and related components sourced from Chinese manufacturers.

Commerce determined that revocation of the antidumping duty order would be likely to lead to continuation or recurrence of dumping at the levels specified in the final results. Accordingly, the existing antidumping duties on these products remain in effect.
Scope of the Order
The order applies specifically to large vertical shaft engines with displacement between 225 cubic centimeters (cc) and 999cc, as well as parts and components thereof, imported from China. These engines are commonly used in lawn mowers, garden equipment, and other small machinery applications.
What This Means for Shippers
Importers sourcing vertical shaft engines or parts from Chinese suppliers must continue to pay applicable antidumping duties on these products. Verify your HS classification and supplier details; failure to properly declare and pay duties on affected shipments risks liquidation adjustments, penalties, and customs holds. Contact your customs broker or freight forwarder immediately to confirm duty obligations and ensure compliance with landed-cost calculations for any pending or future orders.
