Polybutylene Resin PB-01 from Germany
Polybutylene resin PB-01 is a high-purity thermoplastic polymer in primary pellet form, consisting of at least 95% butene-1 monomer units by weight. It is used in hot-melt adhesives and pipe manufacturing due to its flexibility and creep resistance. Classified under HTS 3902.90.0010 as polybutylene per subheading note (a)(1), as the named monomer contributes over 95% of the polymer content.

Import Tips
• Verify monomer composition via certificate of analysis to confirm ≥95% butene-1 content for 3902.90.0010 classification
• Ensure primary form (pellets/granules) with no additives exceeding trace levels to avoid reclassification as chemically modified
