Bourns 3590S Precision Wirewound Potentiometer from Canada
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
