Clobazam and methyprylon are controlled benzodiazepine-class and piperidinedione-class substances used as anticonvulsant and sedative-hypnotic active pharmaceutical ingredients (APIs), respectively, and their import is subject to DEA scheduling requirements in addition to FDA oversight. India and Italy are the leading US suppliers under this heading, reflecting established API manufacturing infrastructure in both countries. Both substances classify under a single 10-digit line (2933720000), but importers must ensure DEA import permits and FDA prior-notice or drug import procedures are satisfied before shipment arrives at the port of entry. Admissibility is complex; consult a licensed customs broker and verify current DEA and FDA requirements with the relevant agencies.

Both substances are DEA-scheduled controlled substances, requiring a valid DEA importer registration and import permit for each shipment. FDA drug import procedures also apply, including prior notice and compliance with current Good Manufacturing Practice (cGMP) standards at the foreign manufacturing site. Importers should coordinate with both agencies well in advance of shipment.
India has a large generic API manufacturing base with extensive FDA-registered facilities, while Italy hosts several specialty pharmaceutical chemical producers with long-standing expertise in controlled-substance synthesis. Both countries supply finished APIs that meet international pharmacopeial standards required for US drug product manufacturing.
