Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the product is a different named basic dye like Disperse Blue variants
Heading 3204.11 covers other specific basic dyes; exact chemical name determines subheading.
If for basic dye preparations dispersed in aqueous media for direct application
Preparations based on basic dyes per note 3 fall under 3204.19 when not pure compounds.
If sold as part of a multi-component dye formulation mixture
Complex dye mixtures with >50% non-coloring chemicals classify as chemical preparations in Chapter 38.
