Compliance steps

1
If the substance figures in the Schedule to the Insecticides Act, 1968, obtain registration and an import permit from the Secretariat of the Central Insecticides Board and Registration Committee before shipment. Route the consignment only through places notified under Rule 45 of the Insecticides Rules, 1971; diversion to an unnotified port renders the consignment liable to detention and seizure.

2
Where the substance is classifiable as an NDPS item, obtain an import certificate under Rule 53 of the NDPS Rules, 1985 for medical or scientific use; all other imports are governed by Appendix-I to the ITC (HS) Schedule. Upload mandatory e-Sanchit documents — certificate of analysis (0010dc), batch release certificate (0030dc), label of consignment (0110dc), registration certificate for drugs (101dc1), and import licence for drugs (9111dc) — before out-of-charge.

3
Ensure the import declaration includes all mandatory additional qualifiers stipulated in paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus for Chapter 29 commodities, with effect from 15 October 2023. Where the quantity of specified hazardous substance exceeds the threshold prescribed under S.O. 227(E) dated 24-03-1992, take out a public liability insurance policy under the Public Liability Insurance Act, 1991.

A word of counsel

The most common error on this tariff line is assuming that CIB&RC registration and NDPS controls are mutually exclusive — in fact, both regimes may attach simultaneously to the same consignment of N-ethyl-2-pyrrolidone depending on its declared end-use. An importer who clears the CIB&RC permit but neglects to verify whether the substance is also caught by the NDPS Appendix-I controls faces consignment seizure and criminal liability under the Narcotic Drugs and Psychotropic Substances Act, 1985, independent of any Insecticides Act contravention.

Frequently asked

Does HSN 2933 79 20 require BIS certification?

No. No BIS Quality Control Order covers this product family. Import is governed by the Central Insecticides Board and Registration Committee under the Insecticides Act, 1968, with concurrent controls under the NDPS Rules, 1985 and DGFT ITC (HS) policy condition 2 of Chapter 29.

Which ports are notified for import of insecticides under Rule 45 of the Insecticides Rules, 1971?

The places at which insecticides may be imported are restricted to those notified under Rule 45 of the Insecticides Rules, 1971; the current list should be confirmed with the CIB&RC Secretariat before booking the shipment.

What triggers the NDPS import-certificate requirement versus the CIB&RC permit requirement for this HSN?

The NDPS import certificate under Rule 53 of the NDPS Rules, 1985 is required where the substance is imported for medical or scientific purposes; imports outside that category fall under Appendix-I of the ITC (HS) Schedule. The CIB&RC permit is triggered if the substance appears in the Schedule to the Insecticides Act, 1968, irrespective of the NDPS classification.
