DL-Phenylephrine Base
DL-Phenylephrine base is the free amine form of the sympathomimetic drug used in nasal decongestants and eye drops, explicitly named in HTS 2922.50.10.00 as an aromatic amino-alcohol-phenol. It features phenolic OH, alcoholic OH, and amino groups on benzene ring.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for simple aromatic amino-alcohols without phenolic function
Lacks the dual oxygen functions (phenol + alcohol) required for 2922.50 grouping.
If when imported as hydrochloride salt in medicinal doses
Pharmaceutical salts formulated for retail/consumer use shift to Chapter 30.
If containing additional heterocyclic oxygen structure
Chapter notes prioritize heterocyclic classification over acyclic oxygen-function amino-compounds.

Import Tips & Compliance
• FDA import alert screening required; provide DMF or bulk drug substance certification
• Controlled substance documentation if precursor potential; CAS 614-19-7 verification needed
• Store/transport under inert atmosphere to prevent oxidation of phenolic groups
