Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If sold as part of mixed antioxidant formulation
Mixtures of antioxidants and stabilizers fall under 3812.39.10 rather than single specified compounds.
If impure or contains other chemical substances
Preparations not purely the named compound may classify as other chemical preparations in 3824.
If imported as bulk heterocyclic compound without plastic stabilizer labeling
As a piperidine derivative, it could classify under Chapter 29 heterocyclic compounds if not presented as rubber/plastic stabilizer.
