Import Tips & Compliance
• Provide end-use statement confirming rubber accelerator application to avoid chemical weapon precursor scrutiny
• TSCA certification required for US manufacture/import; include inventory status documentation
• Not classifiable as organo-sulfur under 2930.90 due to nitrogen heterocyclic principal character
