A word of counsel

The most common error on this tariff line is assuming that CIB&RC applicability is universal and filing for the pesticide permit when the specific substance imported does not appear in the Schedule to the Insecticides Act, 1968 — or conversely, failing to check the Schedule and importing without registration when the substance does appear. Applicability is substance-specific, not category-wide; misclassification in either direction results in either unnecessary detention or unlicensed import of a scheduled insecticide. Additionally, the Public Liability Insurance Act, 1991 insurance obligation under S.O. 227(E) dated 24-03-1992 is routinely overlooked for consignments of specified hazardous substances exceeding the threshold quantities.
