This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If declared as vitamin rather than chemical intermediate
Vitamin classification under provitamins and vitamins supersedes lactone heading.
If buffered with citrates or phosphates
Stabilized formulations become chemical preparations.
If pre-mixed food additive preparations
Food preparations exceed pure chemical compound definition.
