A word of counsel

The most common error on this tariff line is treating the drug-documentation bundle (certificate of analysis, batch release, import licence) as the complete compliance obligation while overlooking the CIB&RC registration and port-restriction requirement that applies independently whenever the substance appears in the Insecticides Act Schedule. An importer who clears the drugs-regime documents but arrives at a non-notified port faces consignment detention under Rule 45 of the Insecticides Rules, 1971 regardless of whether all e-Sanchit uploads are current.
