Compliance steps

1
Verify whether the substance is listed in the Schedule to the Insecticides Act, 1968; if so, obtain registration and an import permit from the Secretariat of the Central Insecticides Board and Registration Committee before shipment. Import is restricted to the notified places under Rule 45 of the Insecticides Rules, 1971, and routing to an unnotified port will result in detention or seizure.

2
Where the substance attracts NDPS controls, obtain an import certificate under Rule 53 of the NDPS Rules, 1985 for medical or scientific purposes, or confirm that importation otherwise qualifies under Appendix-I to the ITC (HS) Schedule. Upload mandatory documents — certificate of analysis (drug) [0010dc], batch release certificate [0030dc], label of consignment [0110dc], registration certificate (drugs) [101dc1], and import licence for drugs [9111dc] — in e-Sanchit before filing the bill of entry.

Ensure the import declaration includes the mandatory additional Chapter 29 qualifiers required under paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus with effect from 15 October 2023. Where the substance exceeds specified quantities of hazardous chemicals, the owner must obtain an insurance policy under the Public Liability Insurance Act, 1991 as per S.O. 227(E) dated 24-03-1992.

A word of counsel

The most frequent error on this tariff line is filing without confirming whether the substance triggers both the CIB&RC insecticide regime and the NDPS overlay simultaneously — each requires distinct pre-import authorisation and e-Sanchit document uploads. A consignment lacking the NDPS import certificate alongside the CIB&RC permit will be detained for PGA NOC verification regardless of CBIC out-of-charge processing, accruing demurrage and ground rent at the designated port while the deficit document is regularised.
