Import Tips
• Include TSCA certification as benzidine derivative; EPA tracks these under chemical import rules
• Label packages with CI 11210 and full chemical name to prevent reclassification during inspection
• Verify no tannin mordant additives, as that shifts to derivative exclusions in chapter notes
