Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If when put up in forms for fire extinguishers
Chapter notes exclude fire-fighting preparations from Chapter 29, directing to heading 3813.
If considered an amine salt without prominent oxygen function
Amine-function compounds precede oxygen-function in numerical order per classification rule.
If for inorganic salts of organic compounds
Note 1(C)(1) may apply salts to inorganic headings if organic component secondary.
