Products classified under HTS 7407.29.16.10
Nickel Silver Hollow Extruded Profile for Musical Instrument Valves
Hollow extruded profile from copper-nickel-zinc alloy (nickel silver, 65Cu-18Ni-17Zn), used in manufacturing trumpet and valve components for its acoustic properties and corrosion resistance. Falls under HTS 7407.29.16.10 as a profile of copper-nickel-zinc base alloy with nickel ≥5%. The specific cross-sectional shape qualifies it as a profile rather than bar.
Cupro-Nickel Hollow Profile Rod for Marine Propulsion Shafts
Hollow profile rod made from copper-nickel base alloy (90/10 cupro-nickel), designed for use in marine propeller shafts due to its excellent corrosion resistance in seawater. Classified under HTS 7407.29.16.10 as a hollow profile of copper-nickel base alloy. The uniform cross-section and extruded form distinguish it from bars or rods.
Cupro-Nickel 70/30 Hollow Profile for Desalination Plant Piping
Hollow profile extruded from 70Cu-30Ni alloy for heat exchanger and piping systems in desalination plants, offering superior resistance to seawater corrosion and biofouling. HTS 7407.29.16.10 applies due to copper-nickel base alloy composition (nickel predominates) and hollow profile form. Used in straight lengths for subsequent fabrication into fittings.
Nickel Silver Hollow Architectural Profile for Luxury Hardware
Decorative hollow profile from nickel silver alloy for high-end door handles, cabinet hardware, and architectural trim, valued for tarnish resistance and golden color. Classified HTS 7407.29.16.10 as copper-nickel-zinc base alloy hollow profile with specific ornamental cross-section. Extruded for further machining and plating.
Cupro-Nickel Hollow Profile Tube for Offshore Oil Platform Risers
Specialty hollow profile from 90/10 cupro-nickel for flexible riser components in offshore oil platforms, providing corrosion resistance under high pressure. HTS 7407.29.16.10 due to copper-nickel base alloy and non-circular hollow profile design for structural reinforcement. Supplied in controlled lengths for welding.
Nickel Silver Hollow Profile for Precision Optical Instrument Mounts
Hollow micro-profile extruded from nickel silver for mounting rings in high-precision telescopes and camera lenses, chosen for dimensional stability. Meets HTS 7407.29.16.10 criteria as copper-nickel-zinc base alloy hollow profile with complex cross-section. Precision tolerances maintained during extrusion.
Cupro-Nickel Hollow Condenser Profile for Power Plant Cooling
Hollow profile from 90/10 cupro-nickel designed for enhanced surface area in steam turbine condensers, optimizing heat transfer in power generation. Classified under HTS 7407.29.16.10 for copper-nickel base alloy hollow profiles. Finned or enhanced cross-section distinguishes from standard tubes.
Nickel Silver Hollow Profile for Luxury Pen Mechanisms
Precision hollow profile extruded from nickel silver for ballpoint and fountain pen refill mechanisms and clips in luxury writing instruments. HTS 7407.29.16.10 applies to this copper-nickel-zinc base alloy hollow profile with custom cross-sections. Provides durability and premium finish before plating.
Cupro-Nickel Hollow Structural Profile for Chemical Processing
Hollow structural profile from 70/30 cupro-nickel for corrosion-resistant supports in chemical reactors and distillation columns. Classified HTS 7407.29.16.10 due to copper-nickel base alloy composition and engineered hollow profile cross-section for weight reduction. Used in aggressive chemical environments.
Nickel Silver Hollow Profile for Marine Compass Housings
Hollow profile extruded from nickel silver for non-magnetic compass housings in nautical instruments, providing corrosion resistance and low magnetic interference. Falls under HTS 7407.29.16.10 as copper-nickel-zinc base alloy hollow profile. Complex curvature maintained in extrusion process.
