C101 Refined Copper Rectangular Bar
A high-purity C101 refined copper bar with a rectangular cross section, typically used in electrical busbars and heat exchangers. It falls under HTS 7407.10.50.10 as a bar of refined copper with rectangular cross section, excluding hollow profiles. Composed of oxygen-free electronic (OFE) copper for superior conductivity.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If made of copper-zinc base alloys (brass)
Brass bars with rectangular cross section shift to copper alloy subheading per Chapter 74 note (a), where zinc predominates over other elements.
If supplied in coil form rather than straight lengths
Powder or unwrought forms including coils classify under Chapter 74 heading 7406, not finished bars/profiles.
If machined into finished articles or parts
Machined copper components become 'other articles of copper' under 7419, not raw bars/rod material.

Import Tips & Compliance
• Provide mill test certificates verifying refined copper purity (99.99%+ Cu) and rectangular cross-section dimensions to avoid reclassification
• Declare exact cross-sectional shape as rectangular (not square or hollow) with precise measurements; common pitfall is mismeasuring profiles
• Ensure compliance with ASTM B187 standards for documentation to prevent customs holds on high-value copper imports
