Subheadings
Products classified under HTS 7407.29.16
Hollow Brass Square Profile Rod
A hollow square profile rod made from copper-zinc base alloy (brass) used in architectural handrails and structural frameworks. It falls under HTS 7407.29.16 as a hollow profile of copper alloy, specifically brass where zinc predominates over other elements except copper. These profiles are extruded for strength and lightness in construction applications.
Hollow Bronze Rectangular Profile
Hollow rectangular profile extruded from copper-tin base alloy (bronze) for marine hardware and fittings. Classified under HTS 7407.29.16 as a hollow profile of copper alloy where tin predominates over other elements (or meets bronze criteria with zinc <10%). Ideal for corrosion-resistant structural components.
Hollow Nickel Silver Round Profile Tube
Hollow round profile made from copper-nickel-zinc alloy (nickel silver, Ni ≥5%) used in decorative trim and musical instrument components. HTS 7407.29.16 covers hollow profiles of such copper alloys per subheading note (c). Provides polished finish and durability.
Hollow Brass I-Beam Profile
Structural hollow I-beam profile of brass alloy for lightweight architectural supports and machinery guards. Falls under HTS 7407.29.16 as hollow profile of copper-zinc alloy. Engineered for high strength-to-weight ratio.
Hollow Copper-Nickel Profile Bar
Hollow profile bar of copper-nickel base alloy (zinc ≤1%) for heat exchanger supports and desalination equipment. HTS 7407.29.16 applies to hollow profiles of this alloy per note (d). Excellent corrosion resistance in harsh environments.
Hollow Admiralty Brass Profile
Hollow profile of admiralty brass (copper-zinc-tin alloy, Sn <3%) for condenser tubesheets and fittings. Remains under HTS 7407.29.16 as brass profile despite minor tin. Optimized for seawater applications.
Hollow Aluminum Brass Oval Profile
Oval hollow profile of aluminum brass (Cu-Zn-Al alloy) for radiator cores and marine condensers. HTS 7407.29.16 as copper alloy hollow profile. Enhanced corrosion resistance via aluminum addition.
Hollow Leaded Brass Hex Profile
Hexagonal hollow profile of leaded brass for machinable fittings and valve bodies. Under HTS 7407.29.16 as brass alloy profile. Lead improves machinability.
Hollow Naval Brass T-Profile
T-shaped hollow naval brass profile (arsenic-doped for dezincification resistance) for shipbuilding. HTS 7407.29.16 hollow copper alloy profile.
Hollow Silicon Bronze Channel Profile
U-channel hollow profile of silicon bronze for welding applications and sculpture. HTS 7407.29.16 as Cu-Si-Sn bronze alloy profile.
Hollow Cupro-Nickel 90/10 Profile
90Cu-10Ni hollow profile for offshore platforms. HTS 7407.29.16 copper-nickel hollow.
Hollow Manganese Bronze L-Profile
L-shaped hollow manganese bronze profile for propellers. Bronze alloy per notes.
Hollow Duralumin Bronze Profile
High-strength hollow profile blending bronze with Al. Still copper alloy profile.
Hollow Red Brass Angle Profile
Angle hollow profile of high-copper red brass for plumbing. HTS 7407.29.16.
Hollow Yellow Brass Z-Profile
Z-profile hollow yellow brass for flashing. Standard brass profile.
