Products classified under HTS 2939.19.20.00
Fentanyl Citrate
Fentanyl citrate is a synthetic opioid analgesic derived from opium alkaloids, used primarily for severe pain management in medical settings. It falls under HTS 2939.19.20.00 as a synthetic derivative of opium alkaloids, specifically classified among other synthetic alkaloids and their salts. This pure chemical compound is supplied as a powder or solution for pharmaceutical formulation.
Sufentanil Citrate
Sufentanil citrate is a highly potent synthetic opioid used in anesthesia and critical care pain management. Classified under HTS 2939.19.20.00 as a synthetic derivative of opium alkaloids, it qualifies due to its chemical structure mimicking natural opium alkaloids. This compound is imported as a bulk active pharmaceutical ingredient.
Alfentanil Hydrochloride
Alfentanil hydrochloride is a short-acting synthetic opioid used for intraoperative analgesia. It is classified in HTS 2939.19.20.00 as a synthetic opium alkaloid salt, fitting chapter 29 provisions for chemically defined organic compounds and their derivatives. Bulk powder form is typical for pharmaceutical manufacturing.
Remifentanil Hydrochloride
Remifentanil hydrochloride is an ultra-short-acting synthetic mu-opioid agonist used in anesthesia. Under HTS 2939.19.20.00, it qualifies as a synthetic derivative of opium alkaloids per chapter notes defining alkaloid derivatives. Imported as sterile lyophilized powder for hospital compounding.
Carfentanil Citrate
Carfentanil citrate is an extremely potent synthetic opioid used primarily in veterinary medicine for large animal immobilization. It falls under HTS 2939.19.20.00 as a synthetic opium alkaloid derivative, chemically related to fentanyl. Strict controls apply due to its high potency and DEA Schedule II status.
Lofentanil Oxalate
Lofentanil oxalate is a synthetic opioid analgesic structurally derived from opium alkaloids, used in research settings. Classified in HTS 2939.19.20.00 as 'other synthetic' opium alkaloid salts, it meets chapter 29 requirements for pure chemically defined compounds. Typically imported in small research quantities.
Pethidine Intermediate A (NOR)
Pethidine Intermediate A, chemically 1-methyl-4-phenylpiperidine-4-carboxylic acid ethyl ester, is a key synthetic precursor to the opium alkaloid derivative meperidine (pethidine). It is classified under HTS 2939.19.20.00 as a synthetic derivative structurally related to opium alkaloids. Used exclusively in controlled pharmaceutical synthesis.
Tramadol Hydrochloride
Tramadol hydrochloride is a synthetic opioid analgesic with dual mechanism action, chemically related to opium alkaloid structures. Under HTS 2939.19.20.00 as 'other synthetic' opium derivatives, it fits chapter 29 provisions despite atypical opioid classification. Bulk API form for tablet/capsule production.
