Master alloys of copper
3 declarable lines
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.
Products in this heading
- Copper-phosphorus master alloy with 15% phosphorus, used to deoxidize copper melts
- Copper-phosphorus master alloy at 10% phosphorus for bronze casting
- Beryllium copper master alloy for adding beryllium to copper alloys
- Copper-manganese master alloy used as a foundry additive
- Copper-silicon master alloy for making silicon bronze
- Copper-chromium master alloy for precipitation-hardened copper
- Lump or ingot master alloy sold by weight to foundries
How to choose the right subheading
- Phosphorus content by weight: 5% or more but not more than 15% decides the phosphorus line
- Whether the goods are beryllium copper master alloy, which has its own break-out
- Whether the item is a master alloy intended as a melt additive rather than a plain unwrought alloy
- Whether all other composition cases fall to the residual other line
Often confused with
- Heading 7403Unwrought refined copper or unwrought copper alloy that is not a master alloy
Heading 7403 covers refined copper and copper alloys, unwrought, and expressly excludes master alloys of 7405.
- Heading 7404Copper scrap and turnings sent for remelting
Waste and scrap of copper is classified in 7404, not as a master alloy.
- Heading 7406Copper powder or flakes
Powders and flakes of copper fall in 7406 even when alloyed.
- Heading 7407Copper bars, rods and profiles
Solid wrought shapes of copper alloys belong in 7407, not in 7405.
- Heading 7408Copper wire
Wire of copper, including alloy wire, is classified in 7408.
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.
