A narrow strip of phosphor bronze plate, 0.2 mm thick and 20 mm wide, used in manufacturing spring contacts for electronic connectors. It falls under HTS 7409.39.90.30 as it is a copper-tin base alloy (phosphor bronze) in sheet form exceeding 0.15 mm thickness, less than 5 mm thick, and under 500 mm width.
