Products classified under HTS 8483.40.30.80
Industrial Fixed Ratio Gear Reducer
A fixed ratio speed changer that reduces motor speed while increasing torque for industrial machinery such as conveyors and mixers. It falls under HTS 8483.40.30.80 as a fixed ratio speed changer not imported specifically for pulp or paper machines. These gear reducers are essential components in manufacturing equipment requiring precise speed control.
Manual Multi-Ratio Gearbox for Textile Machinery
A mechanical gearbox with multiple manually selectable gear ratios for textile weaving and spinning machines. Classified under HTS 8483.40.30.80 as it provides fixed ratios selected by manual manipulation, distinct from pulp/paper applications. Essential for precise speed control in fabric production equipment.
Variable Ratio Mechanical Speed Changer
A mechanical speed changer with multiple fixed ratios selectable by manual lever operation for packaging machinery. Falls under HTS 8483.40.30.80 as 'other' speed changers with manual ratio selection, excluding pulp/paper uses. Used widely in food processing and bottling lines.
Fixed Gear Multiplier for Conveyor Systems
A fixed ratio gear multiplier that increases rotational speed for conveyor drive systems in warehouses. Classified in HTS 8483.40.30.80 as a speed changer with manually set ratios, not for paper machinery. Critical for material handling applications requiring speed multiplication.
Manual Ratio Speed Changer for Plastic Extruders
Mechanical speed changer with multiple fixed ratios for controlling screw speed in plastic extrusion machines. HTS 8483.40.30.80 classification applies to manually selectable ratio changers excluding paper industry use. Provides precise speed control essential for plastic processing.
Multi-Ratio Gearbox for Metalworking Lathes
Precision gearbox with 12-16 manually selectable ratios for controlling spindle speeds on metal lathes. Falls under HTS 8483.40.30.80 as fixed ratio speed changer for machine tools, not pulp equipment. Essential for machinists requiring exact cutting speeds.
Fixed Ratio Right Angle Gear Drive
Compact 90-degree fixed ratio gear drive for mounting motors perpendicular to driven equipment. Classified HTS 8483.40.30.80 as manual ratio speed changer for general industrial use excluding paper processing. Common in pump and fan applications.
