A word of counsel

The most common error on this tariff line is assuming that the CIB&RC registration and NDPS obligations are mutually exclusive — that is, treating a substance as purely an insecticide or purely an NDPS substance when it may independently attract both regimes. CIB&RC scheduling and NDPS scheduling operate under separate statutes; clearance under one does not discharge the other. The Chapter 29 mandatory qualifiers under CBIC Circular 23/2023-Cus are also frequently omitted from import declarations, triggering detention at the bill-of-entry stage.
