HS code 2933.21: Compounds containing an unfused imidazole ring (whether or not hydrogenated) in the structure, hydantoin and its derivatives

HS code 2933.21 covers compounds containing an unfused imidazole ring (whether or not hydrogenated) in the structure, hydantoin and its derivatives. It sits in heading 29.33 (heterocyclic compounds with nitrogen hetero-atom(s) only) in chapter 29 (organic chemicals). Other goods of heading 29.33 are classified under 2933.11 (compounds containing an unfused pyrazole ring (whether or not hydrogenated) in the structure, phenazone (antipyrin) and its derivatives), 2933.19 (compounds containing an unfused pyrazole ring (whether or not hydrogenated) in the structure, other), 2933.29 (compounds containing an unfused imidazole ring (whether or not hydrogenated) in the structure, other), 2933.31 (compounds containing an unfused pyridine ring (whether or not hydrogenated) in the structure, pyridine or its salts) and 22 others. National tariff lines under 2933.21 are live on border.bot for the United States (1 line, also used by 1 other country).
