Compliance steps

1
Determine whether the specific uureine derivative being imported — including Monuron (CML) or Hexaflumuron — is listed in the Schedule to the Insecticides Act, 1968. If scheduled, obtain registration and an import permit from the Secretariat of CIB&RC, and note that import is restricted to places notified under Rule 45 of the Insecticides Rules, 1971.

2
Where the imported substance is a scheduled NDPS substance, obtain an import certificate under Rule 53 of the NDPS Rules, 1985 before shipment. Imports for purposes other than medical and scientific use are governed by Appendix-I to the ITC (HS) Schedule under ITC (HS) policy condition 2 to Chapter 29.

Include mandatory additional qualifiers in the import declaration as required by CBIC Circular 23/2023-Cus dated 30-09-2023 for Chapter 29 commodities, with effect from 15-10-2023, per paras 4.1 and 4.2 of that Circular. Where the import of specified hazardous substances exceeds notified quantities, obtain 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 residual tariff line is filing without first checking the Schedule to the Insecticides Act, 1968: because the CTI is a catch-all 'Other' entry, the CIB&RC obligation is substance-specific and is triggered silently. An importer who ships without a CIB&RC registration and import permit for a scheduled substance faces consignment seizure and criminal liability under the Insecticides Act, 1968 — the CBIC Chapter 29 mandatory-qualifier regime under Circular 23/2023-Cus is a separate, parallel obligation and does not substitute for the PGA clearance.

Frequently asked

Does HSN 2924 21 90 require BIS certification?

No, this tariff line 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, and by NDPS Rules, 1985 where the substance is a scheduled narcotic or psychotropic substance.

Are all ureines under this CTI subject to CIB&RC registration, or only specific substances?

Only substances listed in the Schedule to the Insecticides Act, 1968 require CIB&RC registration and an import permit; confirmed scheduled substances under this CTI include Monuron (CML) and Hexaflumuron. Importers must verify the current Schedule before each shipment, as unlisted substances are not subject to the CIB&RC permit requirement.

What happens if a consignment of a scheduled NDPS substance is imported without the Rule 53 import certificate?

Import without the certificate required under Rule 53 of the NDPS Rules, 1985 constitutes a contravention of Chapter VII-A of those Rules, exposing the consignment to seizure and the importer to criminal prosecution; DGFT ITC (HS) policy condition 2 to Chapter 29 governs permissible non-medical/non-scientific imports via Appendix-I.
