N345034 · 2025-01-15 — The tariff classification of gear reducer from China
Descriptive information was provided in your request. The product at issue is referred to as the SN-90 fixed-ratio planetary gear reducer. The gear reducer, which is configured as a planetary gearbox, is designed to be bolted to a separately imported motor, which receives rotational power from the driveline. Once the system is in operation, the input rotation received by the gears is immediately transferred to the output shaft at a constant ratio of 20/1. The gear reducer transmits power within a conveyor packaging machine that packages and seals food products. In your letter, you suggest the…
N296206 · 2018-05-15 — The tariff classification of gear reducers from China
Descriptive information was provided. The speed changer gear reducers, part numbers 5964 and 5965, are gearing mechanisms described as parts of a paint mixing machine. Each gear reducer is designed to be attached to an electric motor and a paint mixer shaft. Both gear reducers operate a fixed ratio of 20:1 and transfer the rotary force from the motor to a paint mixer shaft that rotates to mix paint. The applicable subheading for the speed changer gear reducers, part numbers 5964 and 5965, will be 8483.40.5010, HTSUS, which provides for Transmission shafts (including camshafts and crankshafts)…
