HS Code for Secobarbital

Secobarbital is a barbiturate derivative that functions as a central nervous system depressant, primarily used as a sedative or hypnotic. In the Harmonized System, it is classified under Chapter 29, which covers organic chemicals. Specifically, it falls under heading 29.33, which is reserved for heterocyclic compounds with nitrogen hetero-atom(s) only. Within this heading, subheading 2933.53 specifically lists Secobarbital (INN) and its salts, alongside other barbiturates like amobarbital and phenobarbital. This classification is strictly based on the chemical's molecular structure—a pyrimidine ring (a six-membered ring with two nitrogen atoms). Because Secobarbital is a regulated pharmaceutical substance, its classification is also influenced by international conventions on psychotropic substances, such as the 1971 Convention on Psychotropic Substances. The HS code 2933.53 is used for the bulk chemical form of the drug. If the product were prepared in measured doses for retail sale as a medicament, the classification would shift to Chapter 30, but as a pure chemical compound or salt, it remains in 2933.53. This distinction is critical for customs clearance, as Chapter 29 items are often subject to different regulatory oversight than finished pharmaceuticals in Chapter 30.

Common Misclassification

The most common misclassification is under 3004.40, which covers medicaments containing alkaloids or their derivatives. While Secobarbital is a medicine, it is only classified in Chapter 30 if it is in measured doses or packaged for retail sale. Another error is using 2933.52, which covers malonylurea (barbituric acid) and its salts, but Secobarbital is a specific derivative that belongs in 2933.53.
