Compliance steps

1
Determine whether the specific substance falls within the Schedule to the Insecticides Act, 1968. If it does, obtain registration and an import permit from the Secretariat of CIB&RC before shipment; import of scheduled insecticides is also restricted to ports specified under Rule 45 of the Insecticides Rules, 1971.

Where the substance is a scheduled narcotic drug or psychotropic substance, obtain an import certificate under Rule 53 of the NDPS Rules, 1985 for medical or scientific purposes as per Chapter VII-A of those Rules. Imports outside this category are governed by Appendix-I to the ITC (HS) Schedule.

File the bill of entry with mandatory additional qualifiers for Chapter 29 commodities as required under paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus, effective 15 October 2023. Upload mandatory documents — certificate of analysis (0010dc), batch release certificate (0030dc), label of consignment (0110dc), registration certificate for drugs (101dc1), and import licence for drugs (9111dc) — in e-Sanchit before out-of-charge.

A word of counsel

The most common error on this tariff line is filing without first resolving which regulatory track applies: CIB&RC insecticide registration, NDPS import certificate, or neither. Substances in this residual 8-digit category are chemically diverse — some fall under the Insecticides Act schedule, some under the NDPS schedule, and some under neither — yet CBIC's Chapter 29 qualifier obligation under Circular 23/2023-Cus applies to all of them regardless of PGA track. Uploading the Chapter 29 qualifiers without confirming PGA clearance, or vice versa, will result in consignment detention at the port.
