Alternative Classifications

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

8533.21.00Same rate: 35%

If for stamped metal grid construction instead of wirewound

Variable resistors with stamped grids classify under 8533.21, separate from traditional wirewound types.

8479.89Lower: 12.5% vs 35%

If imported as integral part of complete machinery, not separately

Parts of machines not specified elsewhere may fall under 8479 if presented in assemblies.

9033.00Lower: 14.4% vs 35%

If when configured as precision parts of measuring instruments

Parts exclusively for instruments/apparatus of Chapter 90 shift to 9033.

Import Tips & Compliance

Provide technical drawings showing wiper and wound element to distinguish from fixed resistors during customs review

Declare exact wattage rating (e.g

2W) as it affects duty verification; pitfalls include generic 'resistor' descriptions

Bundle with end-use certificates if for military/aerospace to preempt ITAR scrutiny
