Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If master alloys for wire production
Master alloys of copper with specific deoxidants classify under 7405, not refined copper.
If for other unwrought copper alloy forms
Unwrought alloys not fitting brass/bronze/nickel notes go to general copper alloy subheading.
If pre-drawn into insulated electrical wire
Finished insulated copper wire for voltage ≤1000V falls under Chapter 85 electrical articles.

Import Tips & Compliance
• Require supplier affidavits on oxygen/impurity levels (<10 ppm) for refined copper validation
• Opt for insured shipping due to high value and sensitivity to contamination during transit
• Monitor anti-dumping duties from specific origins like certain Asian producers
