3906.90.10.00/Acrylic Elastomeric Polymer Resin/Mexico

Acrylic Elastomeric Polymer Resin from Mexico

A primary form acrylic polymer resin classified as elastomeric due to its rubber-like elasticity and recovery properties after stretching. It meets the criteria under HTS 3906.90.10.00 because it is an acrylic polymer where the acrylic monomer units contribute over 95% by weight, and it exhibits elastomeric behavior as specified in the subheading. Used in adhesives and sealants.

Import Tips

• Verify monomer composition via lab analysis to confirm 95%+ acrylic content for elastomeric classification under subheading note (a)(1)

• Provide certificates of analysis (COA) documenting elastomeric properties to avoid misclassification as non-elastomeric acrylics

• Avoid common pitfall of blending with other polymers exceeding 5%, which shifts to predominant monomer subheading
