Import Tips
• Provide certificates of analysis confirming purity and stabilizer content to comply with chapter impurity allowances
• Avoid retail-ready packaging; bulk industrial shipments maintain chapter 29 classification over chapter 32
• Check EPA pre-manufacture notices if not previously registered under TSCA for new dye intermediates
