7409.90.90.30/Beryllium Copper Spring Strip/China

Beryllium Copper Spring Strip from China

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.

Import Tips

• 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
