CIB&RC CLEARANCE · NDPS CLEARANCE

HSN 2933 79 90 (other lactams) is subject to dual primary regulation: items falling under the Schedule to the Insecticides Act, 1968 require registration and an import permit from the Central Insecticides Board and Registration Committee (CIB&RC) under Rule 45 of the Insecticides Rules, 1971; substances meeting the Narcotic Drugs and Psychotropic Substances (NDPS) definition require an import certificate under Rule 53 of the NDPS Rules, 1985. The Directorate General of Foreign Trade (DGFT) ITC (HS) policy condition 2 of Chapter 29 and Central Board of Indirect Taxes and Customs (CBIC) Circular 23/2023-Cus dated 30-09-2023 apply as additional customs-level overlays.

Compliance steps

1
Determine whether the specific lactam falls under the Schedule to the Insecticides Act, 1968. If so, obtain registration and an import permit from the secretariat of CIB&RC before shipment, and confirm that the import port is among those restricted under Rule 45 of the Insecticides Rules, 1971. Diversion to a non-permitted port constitutes a separate statutory violation.
Insecticides Act, 1968 · Rule 45 of the Insecticides Rules, 1971
2
If the substance is an NDPS-scheduled compound, obtain an import certificate under Rule 53 of the NDPS Rules, 1985 for medical or scientific purposes under Chapter VII-A of those Rules; imports outside that category are governed by Appendix-I of the ITC (HS) Schedule per ITC (HS) policy condition 2 of Chapter 29. Upload mandatory e-Sanchit documents — certificate of analysis (0010dc), batch release certificate (0030dc), consignment label (0110dc), registration certificate for drugs (101dc1), and import licence for drugs (9111dc) — before customs out-of-charge.

3
Comply with CBIC Circular 23/2023-Cus dated 30-09-2023 by including mandatory additional qualifiers in the import declaration for Chapter 29 commodities, as stipulated in paragraphs 4.1 and 4.2, with effect from 15-10-2023. Additionally, where the consignment of specified hazardous substances exceeds notified quantities, take out a public liability insurance policy under the Public Liability Insurance Act, 1991 per S.O. 227(E) dated 24-03-1992.

A word of counsel

The most common error on this tariff line is treating the CIB&RC and NDPS regimes as mutually exclusive — in practice, a single lactam compound may simultaneously fall under the Insecticides Schedule and carry NDPS characteristics, triggering both registration/permit requirements and the Rule 53 import-certificate obligation. Importers who clear the CIB&RC permit but overlook the NDPS import certificate face seizure and criminal liability under the Narcotic Drugs and Psychotropic Substances Act, 1985, which are not curable by retrospective document filing.

Frequently asked

Does HSN 2933 79 90 require BIS certification?

No, other lactams under this residual tariff line fall outside the BIS Quality Control Order regime; no BIS QCO covers this product family. Import is governed by CIB&RC registration and permitting under the Insecticides Act, 1968 where the substance is pesticide-scheduled, and by the NDPS Rules, 1985 where the substance is narcotic- or psychotropic-scheduled.

Which e-Sanchit document codes are mandatory at the bill of entry for drug-category substances under this CTI?

Five documents must be uploaded in e-Sanchit before out-of-charge: certificate of analysis (0010dc), batch release certificate (0030dc), consignment label (0110dc), registration certificate for drugs (101dc1), and import licence for drugs (9111dc).

What happens if the quantity of hazardous substances imported under this CTI exceeds the notified threshold?

The owner is required to take out a public liability insurance policy under the Public Liability Insurance Act, 1991, as notified by the Ministry of Environment and Forests via S.O. 227(E) dated 24-03-1992; failure to do so constitutes a separate statutory contravention independent of the CIB&RC or NDPS clearance.
