Bourns 3590S Precision Wirewound Potentiometer
This is a 10-turn precision wirewound potentiometer designed for industrial control panels and test equipment, featuring a 10k ohm resistance with 0.1% linearity tolerance. It falls under HTS 8533.39.00.80 as a wirewound variable resistor (potentiometer), other than heating types, not covered by more specific subheadings. The conductive wire element wound on a core enables precise resistance adjustment.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If supplied as a fixed resistance device without adjustment mechanism
Fixed resistors without variable taps or wipers classify under 8533.10, excluding rheostats or potentiometers.
If non-wirewound construction like carbon film variable type
Other variable resistors excluding wirewound fall under 8533.29; material of resistive element determines heading.
If imported as discrete electronic components for further assembly, not finished variable resistors
Unfinished electrical machines parts may shift to 8543 if not complete functional resistors.

Import Tips & Compliance
• Verify resistance value, tolerance, and wirewound construction via manufacturer specs to confirm classification under 8533.39
• Include detailed datasheets and invoices specifying 'wirewound variable resistor' to avoid misclassification as fixed resistors (8533.10)
• Ensure RoHS compliance documentation for electronics imports; common pitfall is incorrect power rating declaration
