Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If presented as a certified reference material for laboratory analysis
Diagnostic or laboratory reagents on a backing or in a prepared form fall under Chapter 38.
If the mixture is predominantly nitrogen and SF6 is a minor trace component
The principal component may determine classification, potentially under other inorganic oxygen compounds.
