CIB&RC CLEARANCE · NDPS CLEARANCE

HSN 2917 39 20 (Dioctyl isophthalate and dioctyl terephthalate) is subject to registration and import permit requirements of the Central Insecticides Board and Registration Committee (CIB&RC) under the Insecticides Act, 1968 and Insecticides Rules, 1971, where the substance figures in the Schedule to that Act. Narcotic Drugs and Psychotropic Substances (NDPS) import conditions under Chapter VII-A of the NDPS Rules, 1985 and Directorate General of Foreign Trade (DGFT) ITC (HS) policy condition 2 of Chapter 29 apply as additional clearance requirements, alongside mandatory Chapter 29 qualifiers under Central Board of Indirect Taxes and Customs (CBIC) Circular 23/2023-Cus.

Compliance steps

1
Determine whether the specific substance being imported figures in the Schedule to the Insecticides Act, 1968. If it does, obtain both a registration certificate and an import permit from the secretariat of the Central Insecticides Board and Registration Committee, and route the consignment only through ports notified under Rule 45 of the Insecticides Rules, 1971.

2
If the substance also meets the definition of an NDPS substance, obtain an import certificate under Rule 53 of the NDPS Rules, 1985 for medical or scientific purposes; imports outside that category are governed by Appendix-I to the ITC (HS) Schedule. Confirm compliance with ITC (HS) policy condition 2 of Chapter 29 before filing the bill of entry.

3
Ensure mandatory additional qualifiers are declared in the import declaration for Chapter 29 commodities as stipulated in paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus, with effect from 15 October 2023. Where the import involves specified hazardous substances exceeding prescribed quantities, take out a public liability insurance policy as required under S.O. 227(E) dated 24-03-1992.

A word of counsel

The most common error on this tariff line is assuming that because dioctyl isophthalate and dioctyl terephthalate are primarily used as plasticisers, neither the CIB&RC Schedule nor the NDPS overlay applies. Importers must independently verify whether the substance is listed in the Schedule to the Insecticides Act, 1968 and whether it meets NDPS criteria, as both determinations are substance-specific and consignment detention follows immediately where either clearance is absent at the bill-of-entry stage.

Frequently asked

Does HSN 2917 39 20 require BIS certification?

No, no BIS Quality Control Order covers dioctyl isophthalate or dioctyl terephthalate. Import is governed by the Central Insecticides Board and Registration Committee under the Insecticides Act, 1968 where the substance is scheduled, with an NDPS overlay under the NDPS Rules, 1985 and DGFT ITC (HS) policy condition 2 of Chapter 29.

Are all imports under HSN 2917 39 20 subject to CIB&RC registration, or only certain sub-categories?

CIB&RC registration and import permit requirements apply only where the specific substance figures in the Schedule to the Insecticides Act, 1968; non-scheduled substances under this CTI do not require CIB&RC clearance but remain subject to the Chapter 29 CBIC qualifier requirements and DGFT policy conditions.

What happens if the imported quantity of a hazardous substance under this HSN exceeds the prescribed threshold?

The owner must take out a public liability insurance policy as required under the Public Liability Insurance Act, 1991, per S.O. 227(E) dated 24-03-1992 issued by the Ministry of Environment and Forests; failure to hold the requisite insurance policy constitutes a separate statutory contravention.
