Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as unsintered powder
Pure rhenium powders are unwrought under 8112.12, while sintered items are articles.
If as finished turbine engine components
Parts of gas turbines classify under Chapter 84 based on assembly and function.
If with >1% other base metal alloying
Alloyed sintered parts per Chapter 81 notes go to other base metals.
