Import Tips

• Verify copolymer composition via lab testing to confirm 95%+ MBS comonomer content per subheading note (a)(2); provide manufacturer's technical data sheet as supporting documentation

• Declare as primary form (pellets/granules) to avoid misclassification as compounded articles

• Watch for anti-dumping duties on certain Asian-sourced MBS resins
