Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If stabilizer renders suitable for specific polymerization use
Chapter note (g) excludes additions making product particularly suitable beyond identification/safety.
If pre-polymerized with stabilizer into unsaturated polyester resin
Polymer classification supersedes monomer under Chapter 39 per Section VI notes.
If multiple stabilizers exceed 1% total additives
Mixtures of organic compounds with additives > principal component fall outside Chapter 29 scope.
