Import Tips & Compliance
⢠Verify chemical purity and provide Certificate of Analysis (CoA) to confirm it meets 'chemically defined' criteria under Chapter 28 notes
⢠Include Safety Data Sheet (SDS) due to toxicity; ensure compliance with TSCA and EPA regulations for cadmium compounds
⢠Avoid misclassification as finished pigment products under Chapter 32; ship in bulk powder form
