Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified as polyester derivative
Alternative acetalization chemistry may trigger polyester headings.
If in petroleum solvent solution
Solvent-based polymers often go to Chapter 39 note 3 resins.
If formulated as polyacetal varnish
Paint/coating preparations shift to Chapter 32.
