Impact-Modified MBS Polymer Granules from Germany
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.

Import Tips
• Include FTIR or NMR analysis certificates proving MBS composition; ensure granules average under 5mm to qualify as primary forms
• Avoid declaring with PVC masterbatch to prevent classification as compound under 3904
• Common pitfall: undervaluation based on commodity resin benchmarks
