Phosphor Bronze Thin Strip for Electrical Connectors
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. Phosphor bronze's high strength and conductivity make it ideal for precision electrical components.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If copper-zinc brass alloy instead of phosphor bronze
Brasses (copper-zinc dominant) fall under 7409.19, while phosphor bronze is specifically copper-tin base alloys.
If width 500 mm or more
Width dimension shifts classification from 7409.39 (under 500 mm) to 7409.29 (500 mm+).
If thickness 0.15 mm or less
Plates/sheets ≤0.15 mm thick are profiled under Chapter 74 heading 7407, not 7409.

Import Tips & Compliance
• Verify alloy composition meets phosphor bronze definition (tin predominant, phosphorus added) with mill test certificates to avoid reclassification
• Provide precise thickness and width measurements in entry docs; dimensions under 5mm thick/<500mm wide trigger this subheading
