A word of counsel

The most common error on this tariff line is importing on the basis of a CIB&RC registration alone without separately resolving the NDPS and CWC overlays, which operate as independent licensing tracks — each with its own competent authority and import-certificate requirement. A consignment cleared through CIB&RC but lacking the NDPS import certificate under Rule 53 or the CWC national-authority permission for a Category I or Category IB substance is liable to detention, seizure, and prosecution regardless of the insecticide registration. Verify all three tracks before vessel departure.
