Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

8411.99.90Lower: 37.4% vs 37.5%

If imported as replacement part for larger turbine

Parts of gas turbines fall under 8411.99 regardless of power, not the complete industrial turbine heading.

8471.49.00.00Lower: 32.5% vs 37.5%

If classified with full crystal grower assembly

Complete semiconductor wafer manufacturing machines may take precedence over component turbine classification.

8411.82.80Same rate: 37.5%

If power exceeds 5,000 kW

Turbines over 5,000 kW input power shift to different subheading within gas turbines.
