Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If hydrogenated form
Chemical treatment creating metal hydrogen compounds shifts to Chapter 28.
If used in products meeting high-strength steel note (a), may affect end product classification.
If with slag impurities
Slag contamination classifies as Chapter 26 waste, not pure ferroalloy.
