Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If non-quota halogenated polyamines
Halogenated derivatives not in note 3 classify in the general subheading.
If imported as reactive dye intermediate
Primary pigment/dye function excludes from Chapter 29 per exclusion notes.
If deaminated to dichlorodiphenyl compound
Loss of amine function changes classification to halogenated hydrocarbons in 2903.
