4,4'-Bis(dimethylamino) benzhydrol (Michler's Hydrol)
Michler's hydrol is an aromatic amino-alcohol compound used primarily as an intermediate in the synthesis of dyes and pigments. It features a benzhydrol core with dimethylamino substituents, classifying it under HTS 2922.19.2000 as a specific aromatic amino-alcohol other than those with multiple oxygen functions. This chemically defined organic compound falls within Chapter 29's scope for oxygen-function amino-compounds.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If used directly as a dye or pigment intermediate and put up for retail sale
Finished synthetic organic dyes fall under Chapter 32, excluding pure chemical intermediates of Chapter 29.
If classified primarily by its amine function rather than alcohol
Aminohydroxynaphthalenes and derivatives are in 2921, but amino-alcohols prioritize oxygen function per Chapter 29 notes.
If for the salt form if not qualifying as amino-alcohol salt
Aromatic alcohols without prominent amino function classify under 2906; salts follow the parent compound per note 3(C).

Import Tips & Compliance
• Verify purity certificates and chemical analysis to confirm it matches the exact specification in HTS 2922.19.2000, as impurities may affect classification
• Include Safety Data Sheets (SDS) and intended use documentation to demonstrate it's a separate chemically defined compound for chemical synthesis
• Avoid common pitfalls like misclassifying as a finished dye (Chapter 32); ensure no retail packaging that could shift to heading 3212
