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

General rateNot stated for this line
What most imports pay — countries with normal trade relations, which is nearly all of them.
Special rateNot stated for this line
Only under a trade programme or agreement, and only if the goods qualify. The codes name the programmes.
Column 2 rateNot stated for this line
Only for the few countries without normal trade relations.

This line states no general duty rate, and none is inherited from the lines above it. That is not the same as duty-free: lines in Chapters 98 and 99 are provisions and qualifiers rather than ordinary commodities, and a rate may be stated elsewhere. Check the heading before assuming anything.

Additional duties may apply

This line references Chapter 99, where Section 301, Section 232 and other additional duties live. Those are charged on top of the general rate above and depend on where the goods were made. The rate shown here is therefore not the whole story for every origin.

What the Chapter 99 provisions are

What changed

No recorded change to this line since we began reading the schedule daily. That is the ordinary state: USITC revises it fifteen to eighteen times a year, and most codes are untouched in any given revision.

Email me when this code changes

One email if the duty on 8483 moves, or the line is reworded or withdrawn. USITC publishes revisions without a calendar, and a rate change applies to goods entered from the day it takes effect.

Before you rely on this

Classification and the duties that finally apply to a shipment are a licensed customs broker's call. This page publishes the schedule as USITC does; it does not calculate what an entry will cost.
