Buprenorphine Hydrochloride from United States
Buprenorphine hydrochloride is the hydrochloride salt of the partial opioid agonist buprenorphine, used primarily in medication-assisted treatment for opioid dependence. It falls under this tariff item because buprenorphine (INN) is explicitly listed, and Chapter 29 Note 5(C)(1) directs salts of organic bases to the heading of the parent compound.
