Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If used as luminophores in inks or paints
Products functioning primarily as light-emitting luminophores shift to heading 3206, separate from standard brightening agents.
If for polymer masterbatch incorporation
When pre-dispersed in plastic resins as color concentrates, they classify as polyester resins in Chapter 39.
If chemically defined as disperse dyes
Pure, named synthetic organic dyes for textile coloration fall under 3204.11, not brightening function.

Import Tips & Compliance
• 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
