About heading 7405
Master alloys of copper
Heading 7405 covers master alloys of copper, which are copper-based compositions made to be added to molten metal rather than used as finished metal. The heading is split by composition: one line for master alloys containing 5 to 15% phosphorus by weight, and a residual other line that carries a separate break-out for beryllium copper master alloy. All three declarable lines are duty free under the general (MFN) rate.

Frequently asked questions
What is the HTS code for copper-phosphorus master alloy?
Use 7405.00.10.00 when the master alloy contains by weight 5% or more but not more than 15% of phosphorus. The general (MFN) rate for that line is Free.
What is the duty on beryllium copper master alloy?
Beryllium copper master alloy is classified under 7405.00.60.30. Its general (MFN) rate is Free.
How do I classify a copper master alloy that is not phosphorus-bearing or beryllium copper?
It falls to the residual line 7405.00.60.50, Other. The general (MFN) rate for that line is Free.
