Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for stamped metal grid construction instead of wirewound
Variable resistors with stamped grids classify under 8533.21, separate from traditional wirewound types.
If imported as integral part of complete machinery, not separately
Parts of machines not specified elsewhere may fall under 8479 if presented in assemblies.
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
