Heading 8483
Transmission shafts (including camshafts and crankshafts) and cranks; bearing housings, housed bearings and plain shaft bearings; gears and gearing; ball or roller screws; gear boxes and other speed changers, including torque converters; flywheels and pulleys, including pulley blocks; clutches and shaft couplings (including universal joints); parts thereof
47 declarable lines
Heading 8483 covers mechanical power transmission parts: shafts and cranks, bearing housings and plain shaft bearings, gears and gear boxes, ball or roller screws, flywheels and pulleys, clutches and shaft couplings, and parts. It is split first by article type, then by end use, bearing type, housing style, or whether a part is presented separately.
Products in this heading
- Camshafts and crankshafts for spark-ignition engines
- Housed ball bearing flange units
- Bearing housings and plain shaft bearings
- Gear boxes and speed changers
- Torque converters
- Flywheels and grooved pulleys
- Clutches and universal joints
- Chain sprockets presented separately
How to choose the right subheading
- Identify the article first: shaft, crank, bearing housing, gear box, flywheel, pulley, clutch, coupling, chain sprocket, or part.
- For shafts and cranks, check whether it is a camshaft or crankshaft and whether it is designed solely or principally for a spark-ignition engine or rotary engine; then check chapter 87 vehicle use and motorcycle use.
- For housed bearings and bearing housings, check ball versus roller bearings and flange, take-up, cartridge or hanger versus other style.
- For gears and speed changers, separate torque converters, ball or roller screws, fixed ratio or manually selected speed changers, wind turbine gear boxes, and other speed changers.
- For parts, identify the parent article because chain sprockets, bearing housing parts, gearing parts, and other parts take different lines.
Often confused with
- Heading 8482Bare ball or roller bearings
Bare bearings are classified in 8482; 8483 covers housed bearings and bearing housings.
- Heading 8484Mechanical seals
Mechanical seals are separate from bearing housings and shaft couplings.
- Heading 8425Pulley tackle and hoists
Lifting equipment is in 8425; simple pulleys and pulley blocks are in 8483.
- Heading 8481Taps, cocks and valves
Fluid control valves are not power transmission parts.
