Epoxidized Natural Rubber (ENR) from Germany
ENR results from partial epoxidation of natural rubber's double bonds, improving oil resistance for tire compounds and adhesives. Available in latex or solid bale primary forms. Chemical modification places it definitively under HTS 3913.90.1000.

Import Tips
• Provide FTIR spectra or titration data showing epoxide content to validate chemical derivation
• Specify if latex (aqueous dispersion) or dry form, as both qualify if primary and unmodified further
• Avoid pitfall of 4002 classification if epoxidation <20% and marketed as synthetic-like
