Phosphor Bronze Sheet 6mm Thick
A flat phosphor bronze sheet measuring 6mm in thickness, made from copper-tin base alloy with phosphorus addition for enhanced strength and corrosion resistance. Classified under HTS 7409.39.10.30 due to its bronze composition, thickness exceeding 5mm, and phosphor bronze specification. Commonly used in heavy-duty industrial applications requiring durability.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If copper-zinc brass alloy instead of bronze
Brass alloys (zinc predominant) fall under copper-zinc base alloys heading, not copper-tin bronzes.
If thickness under 5mm
Thinner phosphor bronze plates/sheets (0.15-5mm) are classified in the 'other' thickness category within the same bronze heading.
If supplied in coil form
Coiled phosphor bronze strip, even if >0.15mm thick, moves to Chapter 74 heading for bars/rods/profiles in coils.

Import Tips & Compliance
• Verify alloy composition via certified mill test report to confirm phosphor bronze status (tin predominant, phosphorus present)
• Ensure accurate thickness measurement documentation as exceeding 5mm dictates this subheading over thinner strips
• Avoid misclassification as brass by confirming tin > zinc and no excessive nickel content
