Products classified under HTS 7407.10.50.50
C10100 OF Copper Round Bar
A 1-inch diameter round bar made from Oxygen-Free (OF) C10100 refined copper, used in electrical busbars and heat exchangers. It falls under HTS 7407.10.5050 as 'other' bars and rods of refined copper, excluding high-conductivity hollow rectangular bars. Refined copper ensures purity over 99.9% for superior conductivity.
C11000 Electrolytic Tough Pitch Copper Rod
3/8-inch hexagonal rod of C11000 ETP refined copper for transformer windings and RF connectors. Classified under HTS 7407.10.5050 as 'other' refined copper rods with purity 99.9% Cu. Not hollow rectangular, fits general bars/rods category.
C12200 Phosphorous Deoxidized Copper Profile
Custom L-shaped profile in C12200 DHP copper (0.015-0.040% P) for plumbing fittings and architectural trim. HTS 7407.10.5050 covers this as 'other' refined copper profiles since P content <0.3% per Chapter notes. Refined status maintained for weldability.
C10200 OFHC Copper Square Bar
1/2-inch square bar of Oxygen-Free High Conductivity C10200 copper for semiconductor lead frames. Falls in HTS 7407.10.5050 'other' refined copper bars, purity 99.95% Cu, no oxygen. Excludes hollow high-conductivity types.
C12000 Deoxidized Low Residual Phosphorus Copper Bar
Flat bar 2x0.5 inch C12000 DLR copper for heat exchanger tubesheets. Refined copper per Chapter notes (P<0.3%), HTS 7407.10.5050 'other' bars. Low residuals improve corrosion resistance.
C12500 Low Zinc Refined Copper Profile
T-profile C12500 with 0.4% Zn max for architectural extrusions. Still refined copper since Zn<1% and no predominant alloy element per note (a); HTS 7407.10.5050. Used in decorative building trim.
C10800 Tellurium Copper Rod
