Beryllium Copper Spring Strip
Thin beryllium copper strip used for manufacturing precision springs in electronics and aerospace applications. It falls under HTS 7409.90.90.30 as a copper plate, sheet, or strip of beryllium copper alloy (copper-beryllium base alloy), with thickness exceeding 0.15 mm but less than 5 mm, and width under 500 mm. The high strength and conductivity make it ideal for demanding environments.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If phosphor bronze alloy instead of beryllium copper
Phosphor bronzes (copper-tin alloys) fall under separate subheading 7409.90.10, distinguished by tin predominance over beryllium.
If thickness 5 mm or more
Thicker beryllium copper plates/sheets shift to 7407.22 for plates/sheets >=5 mm, based on thickness threshold.
If width 500 mm or more
Wider strips (>=500 mm) classified under 7409.19 for refined copper alloys, per width dimension criteria.

Import Tips & Compliance
• Verify alloy composition meets beryllium copper definition (Be 0.5-3%) with mill test certificates to avoid reclassification
• Ensure precise measurement of thickness (>0.15mm, <5mm) and width (<500mm); common pitfall is mismeasuring coiled strip
• Comply with REACH/RoHS for beryllium content and provide safety data sheets for hazardous material declarations
