Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as the free base without hydrochloride salt
Salts follow the parent compound per chapter note 3(C)(1), but free bases may fall under earlier subheadings.
If primarily classified by amino-function rather than heterocycle
Chapter notes prioritize oxygen/nitrogen functions in earlier headings like 2922 over heterocyclics.
If imported as finished antidepressant tablets
Medicaments in dosage form are classified in Chapter 30 based on therapeutic use, not chemical structure.

Import Tips & Compliance
• Submit Drug Master File (DMF) to FDA prior to import and reference it on customs entry
• Ensure packaging prevents moisture absorption as hydrochloride salts are hygroscopic
• Classify correctly as API, not finished dosage form, to avoid Chapter 30 reclassification
