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.

7409.90.10Same rate: 38%

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.

7407Lower: 11.6% vs 38%

If thickness 5 mm or more

Thicker beryllium copper plates/sheets shift to 7407.22 for plates/sheets >=5 mm, based on thickness threshold.

7409.19Lower: 13% vs 38%

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
