Dihydrocodeine Tartrate from Japan
Dihydrocodeine tartrate is the tartrate salt of dihydrocodeine, a semi-synthetic opioid analgesic and antitussive derived from codeine. It is covered by this tariff item because dihydrocodeine (INN) is explicitly named, and Chapter 29 Note 5(C)(1) classifies salts of organic bases with the parent compound.
