Compliance steps

1
Where sulphadimidine figures in the schedule to the Insecticides Act, 1968, obtain registration and an import permit from the secretariat of the Central Insecticides Board and Registration Committee before filing the bill of entry. Import is restricted to specified places under Rule 45 of the Insecticides Rules, 1971; consignments arriving at non-specified ports are liable to detention and seizure.

A word of counsel

The most common error on this tariff line is treating the drug-import documentation set (registration certificate, import licence, certificate of analysis) as the sole clearance requirement and overlooking the CIB&RC insecticide-regime overlay and the NDPS import-certificate condition, which are independent obligations activated by the substance's scheduled status. An importer who uploads all five drug-document codes in e-Sanchit but has not verified whether sulphadimidine appears in the Insecticides Act schedule will face consignment detention at a non-specified port, with demurrage accumulating until CIB&RC clearance is produced.
