A word of counsel

The most frequent error on this tariff line is treating CIB&RC clearance as the sole gateway and overlooking the concurrent NDPS-conditions check: even where the substance is not a scheduled insecticide, it may independently attract NDPS Rule 53 import-certificate requirements if it figures on the NDPS schedule. Filing a bill of entry without resolving which of the two regimes — or both — applies to the specific batch causes detention at the port of import and potential seizure, since customs officers are instructed to verify PGA compliance before granting out-of-charge.

Frequently asked

Does HSN 2922 21 80 require BIS certification?

No, Chicago acid is not covered by any BIS Quality Control Order. Import is governed by CIB&RC registration and permit requirements under the Insecticides Act, 1968, with NDPS Rules, 1985 conditions and DGFT ITC (HS) policy condition no. 2 of Chapter 29 applying as concurrent overlays.

Is import of insecticides under this CTI restricted to specific ports?

Yes. Rule 45 of the Insecticides Rules, 1971 restricts import of insecticides to specified places; the permissible ports of entry must be confirmed with CIB&RC before routing the consignment, as diversion to an unspecified port constitutes a violation independent of the registration status.

When does the public liability insurance requirement apply to this HSN?

Where the import involves specified hazardous substances in quantities exceeding the thresholds prescribed under S.O. 227(E) dated 24-03-1992 issued by the Ministry of Environment and Forests, the owner must take out an insurance policy under the Public Liability Insurance Act, 1991 before clearance.
