Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If chemical modification makes it not specifically covered
Note (a)(3) directs unspecified chemically modified polymers to 'Other' subheadings.
If imported as prepared binder for paints/coatings
Prepared chemical mixtures for specific uses shift to Chapter 38 mixtures.
If glycerol or pentaerythritol esters without polymer base
Pure polyhydric alcohol esters classify as acyclic alcohols in Chapter 29.
