Products classified under HTS 2924.29.71.00
Procainamide Hydrochloride
Procainamide hydrochloride is an aromatic cyclic amide derivative used as an antiarrhythmic agent to treat irregular heartbeats. It falls under HTS 2924.29.71.00 as a chemically defined aromatic cyclic amide product listed in additional U.S. note 3 to section VI. This classification applies to its carboxyamide-function structure and pharmaceutical-grade purity.
Lidocaine Hydrochloride
Lidocaine hydrochloride is a local anesthetic and aromatic amide compound used for nerve block and topical anesthesia. Classified under HTS 2924.29.71.00 due to its cyclic amide structure and inclusion in additional U.S. note 3 to section VI. It's a separate chemically defined organic compound meeting chapter requirements.
Bupivacaine Hydrochloride
Bupivacaine hydrochloride is a long-acting local anesthetic amide used in spinal and epidural anesthesia. It qualifies for HTS 2924.29.71.00 as an aromatic cyclic amide derivative specified in additional U.S. note 3. The classification reflects its primary carboxyamide-function chemical structure.
Prilocaine Hydrochloride
Prilocaine hydrochloride is an amino-amide local anesthetic used in dental and minor surgical procedures. Falls under HTS 2924.29.71.00 as a chemically defined aromatic cyclic amide per additional U.S. note 3. Its classification follows chapter rules for carboxyamide-function compounds.
Mepivacaine Hydrochloride
Mepivacaine hydrochloride is an amide-type local anesthetic for infiltration and nerve block anesthesia. Classified in HTS 2924.29.71.00 as an aromatic cyclic amide product described in additional U.S. note 3 to section VI. Meets criteria for separate chemically defined compounds.
Articaine Hydrochloride
Articaine hydrochloride is a unique thiophene-based amide local anesthetic used primarily in dentistry. It qualifies for HTS 2924.29.71.00 as an aromatic cyclic amide listed in additional U.S. note 3, despite sulfur content not dominating classification. The amide function determines heading placement.
Dibucaine Hydrochloride
Dibucaine hydrochloride is a potent amino-acridine amide anesthetic for spinal anesthesia. Falls under HTS 2924.29.71.00 per additional U.S. note 3 as a chemically defined aromatic cyclic amide compound. Classification prioritizes carboxyamide function over other ring systems.
Levobupivacaine Hydrochloride
Levobupivacaine hydrochloride is the S-enantiomer of bupivacaine, offering reduced cardiotoxicity. Classified under HTS 2924.29.71.00 as an aromatic cyclic amide per additional U.S. note 3. Meets chapter requirements for separate chemically defined stereoisomers.
