Products classified under HTS 2934.92.00.00
Fentanyl Citrate
Fentanyl citrate is the citrate salt form of fentanyl, a synthetic opioid classified as a derivative under HTS 2934.92.00.00 due to its specific heterocyclic structure and chemical definition as a fentanyl derivative. It is primarily used in medical settings for anesthesia and pain management.
Sufentanil Citrate
Sufentanil citrate is a potent fentanyl derivative used as an analgesic in surgical procedures, falling under HTS 2934.92.00.00 as a chemically defined other fentanyl. Its structure modifies the fentanyl base with a thiophene ring, qualifying it within this chapter's heterocyclic compounds.
Alfentanil Hydrochloride
Alfentanil hydrochloride is a short-acting synthetic opioid fentanyl derivative, chemically defined and classified under HTS 2934.92.00.00. It features a modified piperidine structure, fitting chapter 29's heterocyclic compounds scope.
Carfentanil Oxalate
Carfentanil oxalate, an extremely potent fentanyl analog used in veterinary medicine, is classified under HTS 2934.92.00.00 as a derivative. Its chemical structure derives directly from fentanyl with modifications for enhanced potency.
Remifentanil Hydrochloride
Remifentanil hydrochloride is an ester-based ultra-short-acting fentanyl derivative for anesthesia, under HTS 2934.92.00.00. It qualifies as a heterocyclic compound per chapter notes on esters classified by parent structure.
Lofentanil Oxalate
Lofentanil oxalate is a long-acting research fentanyl derivative, chemically defined under HTS 2934.92.00.00. Its structure aligns with chapter 29's heterocyclic provisions for such compounds.
Acetylfentanyl
Acetylfentanyl is a synthetic N-acetyl derivative of fentanyl, classified under HTS 2934.92.00.00 as a chemically defined fentanyl derivative. It fits the chapter's scope for separate organic compounds.
Furanylfentanyl
Furanylfentanyl features a furan ring substitution on the fentanyl structure, qualifying as a derivative under HTS 2934.92.00.00. Chapter notes confirm heterocyclic classification.
Butyrylfentanyl
Butyrylfentanyl is an N-butyryl analog of fentanyl, a derivative captured by HTS 2934.92.00.00 for other fentanyls. It is a separate chemically defined compound per chapter note 1(a).
Valerylfentanyl
Valerylfentanyl, with a valeryl group on fentanyl base, is classified under HTS 2934.92.00.00 as a heterocyclic fentanyl derivative. Meets criteria for chapter 29 organic compounds.
Fentanyl Hydrochloride
Fentanyl hydrochloride is the standard salt form of the base fentanyl molecule, directly under HTS 2934.92.00.00 per note 5(C)(1) for organic salts. It is a core heterocyclic opioid compound.
