Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If chemically modified for finishing preparations
Chemically modified polymers used as finishing agents classify in Chapter 38 per subheading note (a)(3).
If blended with modifiers exceeding 5%
Additive blends not covered by specific acrylic subheadings go to 'Other' per note (a)(3).
If imported dissolved in solution over 50% concentration
Primary forms exclude solutions; mixtures with solvents classify as goods of mixed materials.

Import Tips & Compliance
• Test for neutralization degree; fully polymerized forms stay here, partially neutralized may shift to Chapter 38
• Declare exact dry polymer content excluding water/solvent to meet primary forms definition
