High-Impact MBS Copolymer for Medical PVC
High-impact MBS copolymer pellets in primary form, designed for medical-grade PVC applications. The pellets contain methyl methacrylate, butadiene, and styrene comonomers totaling 95% or more by weight, providing clarity and impact resistance without phthalates. Classified under tariff item 3903.90.00 as 'Other' styrene polymers, as MBS is not a named copolymer in subheadings 3903.20 or 3903.30.

More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the copolymer is primarily styrene-acrylonitrile (SAN) rather than MBS
SAN copolymers are specifically named in subheading 3903.20, which would take precedence over the 'Other' subheading.
If the product is actually a polyester-based impact modifier rather than a styrene polymer
Other polymer types with different monomer compositions would fall under different headings.

Import Tips & Compliance
• Verify the pellets are in primary form (e.g
• pellets, granules) and not further worked, as this affects classification
• Keep records of the polymer composition to demonstrate the 95% comonomer threshold
• If the pellets contain additives like stabilizers or colorants, ensure they do not alter the classification under subheading notes
