Import Tips
• Provide masterbatch formulation details to distinguish from plastic colorants in Chapter 32, ensuring proper HTS placement
• Label with CAS number (e.g
• 1533-45-5) and concentration to comply with TSCA import requirements for chemical substances
• Avoid bulk packaging over retail limits to prevent reclassification as industrial preparations under 3824
