CIB&RC CLEARANCE · NDPS CLEARANCE

HSN 2933 71 00 (6-Hexanelactam / epsilon-caprolactam) is subject to dual primary regulatory oversight: the Central Insecticides Board and Registration Committee (CIB&RC) under the Insecticides Act, 1968 where the substance appears in the Schedule to that Act, and the Narcotic Drugs and Psychotropic Substances (NDPS) regime under Chapter VII-A of the NDPS Rules, 1985. The Directorate General of Foreign Trade (DGFT) ITC (HS) policy condition 2 of Chapter 29 governs non-medical/non-scientific NDPS imports, and the Central Board of Indirect Taxes and Customs (CBIC) Circular 23/2023-Cus mandates Chapter 29 additional qualifiers in import declarations with effect from 15 October 2023.

Compliance steps

1
If the specific formulation of this CTI is listed 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 the consignment is shipped. Import of scheduled insecticides is restricted to places notified under Rule 45 of the Insecticides Rules, 1971; shipment to any non-notified port results in detention and potential seizure.

2
Where the substance is being imported for medical or scientific purposes under the NDPS regime, obtain an import certificate under Rule 53 of the NDPS Rules, 1985 (Chapter VII-A) before filing the bill of entry. Ensure the mandatory documents — certificate of analysis (document code 0010dc), batch release certificate (0030dc), label of consignment (0110dc), registration certificate for drugs (101dc1), and import licence for drugs (9111dc) — are uploaded in e-Sanchit before out-of-charge.

Include all mandatory additional qualifiers in the import declaration for Chapter 29 commodities as stipulated in Para 4.1 and 4.2 of CBIC Circular 23/2023-Cus. Additionally, if the import of specified hazardous substances exceeds the specified quantities, take out an insurance policy under the Public Liability Insurance Act, 1991, as required by S.O. 227(E) dated 24-03-1992.

A word of counsel

The most common error on this tariff line is failing to determine upfront whether the specific imported formulation is scheduled under the Insecticides Act, 1968 — a classification question that triggers an entirely separate CIB&RC registration and port-restriction regime. Importers who treat epsilon-caprolactam solely as an organic chemical intermediate and file the bill of entry without the CIB&RC registration certificate face consignment detention at the port of import; the NDPS overlay adds a concurrent check, meaning both regimes must be evaluated before the purchase order is placed.

Frequently asked

Does HSN 2933 71 00 require BIS certification?

No, epsilon-caprolactam is not covered by any BIS Quality Control Order. Import is governed by the Central Insecticides Board and Registration Committee under the Insecticides Act, 1968 where the substance is scheduled, the NDPS Rules, 1985 where NDPS conditions apply, and DGFT ITC (HS) policy condition 2 of Chapter 29.

Which document codes must be uploaded in e-Sanchit at the bill of entry for the NDPS-medical track?

The mandatory uploads are: certificate of analysis — drug (0010dc), batch release certificate (0030dc), label of consignment (0110dc), registration certificate for drugs (101dc1), and import licence for drugs (9111dc), all to be uploaded before customs out-of-charge.

Does the NDPS import certificate under Rule 53 apply to all imports of this HSN?

No. The Rule 53 import certificate applies only to imports for medical and scientific purposes under Chapter VII-A of the NDPS Rules, 1985; imports outside that category are governed by Appendix I to the ITC (HS) Schedule under DGFT policy condition 2 of Chapter 29.
