Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the compound is considered a precious metal compound rather than a cyanide
Section Note 1(B) of Chapter 28 states that goods answering to heading 28.43 (precious metal compounds) are to be classified there, overriding the cyanide heading.
