Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the free acid form without sodium salt
Salts follow the parent organic compound per note (C)(1), but unsalified versions may fall under other 'other' carboxylic derivatives.
If classified as a sugar ester derivative
Sugar-related esters move to heading 2940 per chapter note (c), later in order.
If impure and used as a fertilizer additive
Chapter excludes impure formulations resembling fertilizers, shifting to chapter 31.
