Export classification of inorganic chemicals determines free export status, while nuclear materials require specialised export authorisation.

The listed tariff items carry a Free export policy, including chemical elements, inorganic acids, halides, sulphides, alkalis, metal oxides, salts and compounds of precious and rare-earth metals. Export authorisation from the Department of Atomic Energy is required for exports of Category-0 nuclear materials, nuclear-related materials, equipment and technology under SCOMET. Potassium permanganate remains freely exportable only upon obtaining a No Objection Certificate from the Narcotics Commissioner, Gwalior.
