Import Tips

Verify purity and ensure product meets chemical definition as TBBA without additional functional groups to avoid reclassification under other Chapter 29 headings

Provide Safety Data Sheets (SDS) and TSCA certification, as TBBA is regulated under EPA for chemical import notifications

Watch for REACH compliance documentation if sourced from EU, and avoid common pitfalls like mislabeling as a mixture which shifts to heading 3824
