Import Tips & Compliance
• Verify purity and provide chemical analysis certificates to confirm classification as a separate chemically defined compound under Chapter 29
• Include Safety Data Sheets (SDS) and ensure compliance with TSCA registration for environmental and health regulations
• Avoid misclassification as a finished dye by confirming it's not put up for retail sale, a common pitfall leading to higher duties
