Metol (p-Methylaminophenol Sulfate)
Metol is a developing agent used in black and white photographic film and paper developers. As an amino-phenol derivative with a single oxygen function (phenol), its sulfate salt falls under HTS 2922.29.2900 for photographic chemicals. It is chemically defined and primarily used in photographic processing.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as a concentrate for dye production rather than photo use
o- and p-aminophenols primarily for dyes fall under heading 2921, preceding 2922 numerically.
If imported as formulated developer solution with additives
Mixtures like prepared photographic developers are classified in chapter 38 as artificial graphite or preparations.
If containing both oxygen and nitrogen functions beyond single phenol group
Other organic compounds with nitrogen functions not elsewhere specified go to heading 2942.

Import Tips & Compliance
• Verify purity certificates as impurities may affect classification under chapter 29 note (a)
• Include safety data sheets (SDS) for handling amino-phenol compounds during customs clearance
• Avoid misclassification as general organic chemicals; specify photographic end-use in documentation
