Import Tips

• Verify chemical purity via Certificate of Analysis (CoA) to confirm it meets Chapter 29 definition as a separate chemically defined compound without disqualifying impurities

• Include Safety Data Sheet (SDS) and TSCA certification for EPA compliance, as phthalates face regulatory scrutiny under chemical import rules

• Avoid misclassification as a mixture; ensure packaging labels it solely as DIDP to prevent reclassification under heading 3824 for chemical preparations
