Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If processed into finished medical profiles
Finished plastic medical articles (tubing, bags) go to 3926 or 9018, not primary polymers.
If imported as sterilized ready-to-use dispersion
Sterile polymer dispersions for medical use classified as chemical preparations in 3824.

Import Tips & Compliance
• Include USP Class VI or ISO 10993 biocompatibility certificates; coordinate with FDA prior notice requirements
• Pitfall: medical claims trigger stricter CBP scrutiny - declare as industrial resin only

MBS Copolymer Resin Pellets
Transparent pellets of methyl methacrylate-butadiene-styrene (MBS) copolymer, where the comonomer units of methyl methacrylate, butadiene, and styrene contribute 95% or more by weight of the total polymer content. This specific copolymer is classified under HTS 3903.90.1000 as it falls within the named subheading for MBS copolymers in primary forms. Used primarily as an impact modifier for rigid PVC in manufacturing.
Impact-Modified MBS Polymer Granules
Granular primary form of MBS copolymer designed for high-impact applications, meeting the 95% weight threshold for methyl methacrylate-butadiene-styrene comonomers. Classified specifically under 3903.90.1000 due to the named copolymer designation in the HTS. Commonly added to PVC for clear, tough profiles like window frames.
Clear MBS Copolymer Beads for PVC Toughening
High-clarity MBS copolymer beads in primary form, with precise 95%+ comonomer composition of methyl methacrylate, butadiene, and styrene. This material is explicitly named in subheading 3903.90.1000 for import classification. Essential for producing transparent, impact-resistant PVC sheets and films.
MBS Impact Modifier Powder (Core-Shell Type)
Fine powder form of core-shell MBS copolymer where butadiene core is rubber-modified with MMA/styrene shell, meeting 95% comonomer criteria. Classified under the specific MBS subheading 3903.90.1000 in primary forms. Used in extrusion and injection molding for enhanced toughness.
