Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If aromatic but lacking phenolic oxygen function
Non-phenolic amino-alcohols classified earlier in 2921; oxygen-function requirement excludes from 2922.
If primary use as photographic chemical with nitrogen functions dominating
Compounds emphasizing nitrogen-functions over oxygen classified in later 2929 per note 3 rule of last heading.
If polymerized into polyimide resin
Finished polymers from amino-phenol monomers classified in Chapter 39, not chemical intermediates.

Import Tips & Compliance
• Provide REACH/TSCA registration numbers; diamines trigger inventory reporting for polymer manufacturers
• Technical grade requires COA showing <0.1% heavy metals; polymer intermediates face strict impurity limits
• Ship under proper shipping name 'Phenylemdiamines' UN2650; temperature-controlled <40°C to prevent oxidation
