Bourns 3590S Precision Wirewound Potentiometer from Japan

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 Tips

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
