Import Tips
• Verify monomer composition via lab testing to confirm 95%+ acrylic content for proper Chapter 39 classification
• Provide supplier certificates of analysis (COA) documenting polymer specs to avoid reclassification during CBP exam
• Avoid common pitfalls like mislabeling as copolymers if predominant monomer doesn't meet subheading criteria
