Compliance steps
  1. 1
    If the substance falls within 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 filing the bill of entry. Import is permitted only at restricted places of import under Rule 45 of the Insecticides Rules, 1971; route the consignment accordingly.

  2. 2
    Where the consignment is classified as an NDPS substance, obtain an import certificate under Rule 53 of the NDPS Rules, 1985 before shipment; imports for medical and scientific purposes are processed under Chapter VII-A of those Rules via the Narcotics Commissioner (cbn.nic.in). Imports outside the medical/scientific category are governed by Appendix I to the ITC (HS) Schedule per ITC (HS) policy condition 2 to Chapter 29.

A word of counsel

The most common error on this tariff line is treating the drug-document set (Registration Certificate, Import Licence for Drugs, Certificate of Analysis) as exhaustive and overlooking the CIB&RC registration and restricted-port obligation that applies where the substance also appears in the Schedule to the Insecticides Act, 1968. A consignment cleared with all CDSCO-equivalent drug documents but without the CIB&RC permit, or arriving at an unrestricted port, faces detention and potential seizure under the Insecticides Rules, 1971 independently of the drug-import clearance.

Frequently asked
Does HSN 2921 42 36 require BIS certification?
No. No BIS Quality Control Order covers aniline derivatives such as Methyldopa. Import is governed by the Central Insecticides Board and Registration Committee under the Insecticides Act, 1968, the NDPS Rules, 1985 where the substance is scheduled, and DGFT ITC (HS) policy conditions for Chapter 29.
Which document codes are mandatory in e-Sanchit for this tariff line at the bill of entry?
The five mandatory codes 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 per the e-Sanchit verification requirement confirmed in the CCR.
Do the Chemical Weapons Convention restrictions on nitrogen mustards or CWC Category 1A/1B substances affect the import of Methyldopa under this CTI?
The CWC restrictions cited in the ITC (HS) policy — Appendix II to Schedule I, Categories 1A and 1B — target nitrogen mustards and N,N-dialkyl aminoethyl-2-chlorides specifically; Methyldopa is not a listed CWC precursor, but importers must confirm the precise substance being imported under this CTI does not co-classify under those Appendix entries before filing.
