Compliance steps

1
Determine the intended end-use of the imported substance before filing the bill of entry. Where the substance is a listed medical device under G.S.R. 102(E) dated 11-02-2020, obtain CDSCO registration and upload the registration certificate. Where the substance is imported for insecticidal, fungicidal, herbicidal, or rodenticidal use, obtain a Certificate of Registration or Import Permit from CIB&RC under Section 9 of the Insecticides Act; import from a source not specified on the certificate is prohibited.

Comply with the mandatory additional qualifier requirements for Chapter 29 commodities in the import declaration as stipulated in Para 4.1 and 4.2 of CBIC Circular 23/2023-Cus dated 30-09-2023, with effect from 15-10-2023.

Where the import involves a specified hazardous substance exceeding the threshold quantities, the owner must obtain a Public Liability Insurance policy under the Public Liability Insurance Act, 1991. For imports involving wastes, comply with Rules 12 and 13 of the Hazardous Waste (Management and Transboundary Movement) Rules, 2016 and Para 8(b) of the General Notes of the ITC (HS) import policy.

A word of counsel

The most consequential error on this tariff line is treating the DGFT 'Free' import status as a blanket clearance. Import is Free only subject to policy conditions 3 and 7 of Chapter 29, and the CIB&RC registration requirement under the Insecticides Act is triggered by intended use, not by tariff classification alone — meaning a consignment that is released on a CDSCO registration but subsequently diverted to pesticidal use constitutes an unauthorised import, attracting seizure and criminal liability under the Insecticides Act. The source-of-origin restriction on CIB&RC certificates is equally strict: import from an unlisted source voids the permit.

Frequently asked

Does HSN 2933 41 90 require BIS certification?

No, no BIS Quality Control Order covers this organic chemical tariff line. Import is governed by CDSCO under G.S.R. 102(E) dated 11-02-2020 where the substance qualifies as a listed medical device, and by CIB&RC under Section 9 of the Insecticides Act where the intended use is pesticidal, with DGFT policy conditions 3 and 7 of Chapter 29 applying in all cases.

Is a separate CIB&RC import permit required even when the substance is imported for non-pesticidal purposes?

Yes. Where a chemical classifiable as an insecticide under the Insecticides Act is imported for a non-insecticidal purpose, an import permit from the CIB&RC Registration Committee is still necessary, as confirmed by CBIC Circulars 35/2011 and 7/2014 and Rule 45 of the Insecticides Rules, 1971.

When does the Public Liability Insurance requirement apply to this tariff line?

The insurance obligation under the Public Liability Insurance Act, 1991 is triggered when a specified hazardous substance is imported in quantities exceeding the thresholds prescribed under S.O. 227(E) dated 24-03-1992; the importer must obtain the policy before customs out-of-charge.
