Products classified under HTS 7408.22.50.00
Cupro-Nickel Thermocouple Wire Type T
This is a bare cupro-nickel wire used in Type T thermocouples for temperature measurement in industrial and laboratory settings. It falls under HTS 7408.22.50.00 as it is made from copper-nickel base alloys (with nickel predominating over other elements and zinc under 1%) and is not coated or plated with metal.
Nickel Silver Bare Round Wire 0.5mm
Bare round wire made from copper-nickel-zinc base alloy (nickel silver) with ≥5% nickel, used in precision instruments and jewelry findings. Classified under HTS 7408.22.50.00 due to its uncoated copper-nickel-zinc composition meeting subheading note (c).
Nickel Silver Square Wire for Springs 1mm
Uncoated square-profile nickel silver wire used in manufacturing small mechanical springs and contacts. Falls under HTS 7408.22.50.00 for bare copper-nickel-zinc base alloy wire.
Nickel Silver Flat Wire for Electrical Contacts
Rectangular bare nickel silver wire for stamped electrical connectors and switch contacts. Classified in HTS 7408.22.50.00 as uncoated copper-nickel-zinc base alloy wire.
Constantan Bare Wire for Strain Gauges
High-precision bare constantan (cupro-nickel alloy) wire for strain gauge sensors in engineering applications. HTS 7408.22.50.00 due to copper-nickel base composition, uncoated.
Cupro-Nickel 70/30 Wire for Heat Exchangers
Bare 70/30 cupro-nickel wire used in condenser tube supports and heat exchanger components. Falls under HTS 7408.22.50.00 as uncoated copper-nickel base alloy wire.
Nickel Silver Watch Spring Wire
Precision-drawn bare nickel silver wire for hairsprings in mechanical watches. HTS 7408.22.50.00 for its uncoated copper-nickel-zinc base alloy properties.
