Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If copper-nickel-zinc alloy versions
Nickel silvers (≥5% Ni) per note (c) use separate copper alloy classification.
If flexible polyimide films unclad
Kapton-type polyimide sheets without copper classify as plastics film.

Import Tips & Compliance
• ITAR/EAR export control markings required even on imports—check end-use statements
• Thermal performance specs (Tg, CTE) documentation essential for high-reliability claims
• Small production runs common—ensure minimum order quantities don't trigger special duty rates
