Import Tips
• Label containers with GHS pictograms for skin corrosion/serious eye damage; critical for DOT/CBP hazardous materials compliance
• Provide end-use statement if requested; dye intermediate status prevents shift to finished colorant classification
• Avoid importing in consumer-ready packaging (≤300g) which could trigger retail set exclusions under Chapter notes
