Compliance steps

1
If the consignment falls within the Schedule to the Insecticides Act, 1968, obtain valid registration and an import permit from the secretariat of the Central Insecticides Board and Registration Committee before dispatch. Route the consignment only through the restricted places notified under Rule 45 of the Insecticides Rules, 1971.

2
Submit 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, with effect from 15 October 2023. Non-submission renders the bill of entry deficient and liable to detention at the port of import.

Where the substance is classified as an NDPS substance, obtain an import certificate under Rule 53 of the NDPS Rules, 1985 for medical and scientific purposes; all other NDPS imports are governed by Appendix-I to the ITC (HS) Schedule. Additionally, where import of specified hazardous substances exceeds notified quantities, obtain a public liability insurance policy under the Public Liability Insurance Act, 1991.

A word of counsel

The most common error on this tariff line is assuming isophthalic acid is a straightforward industrial chemical and overlooking its potential listing in the Schedule to the Insecticides Act, 1968. If the specific formulation or mixture is scheduled, the absence of CIB&RC registration and permit at the bill of entry results in consignment detention and potential confiscation — the CIB&RC obligation is triggered by the substance's actual classification against the Schedule, not by the importer's intended end-use.

Frequently asked

Does HSN 2917 39 60 require BIS certification?

No, isophthalic acid is not covered by any BIS Quality Control Order. Import is governed by Central Insecticides Board and Registration Committee registration and permit under the Insecticides Act, 1968 where the substance is scheduled, with NDPS Rules, 1985 controls and DGFT ITC (HS) policy condition 2 of Chapter 29 applying as overlays.

Which ports are notified for import of insecticides under Rule 45 of the Insecticides Rules, 1971?

The places at which insecticides may be imported are restricted under Rule 45 of the Insecticides Rules, 1971; the current notified list should be confirmed with the CIB&RC secretariat before the purchase order is placed, as routing to an unnotified port triggers seizure.

Does the public liability insurance requirement apply to all imports of isophthalic acid?

No — the insurance obligation under the Public Liability Insurance Act, 1991 is triggered only when the import of specified hazardous substances exceeds the quantities notified under S.O. 227(E) dated 24 March 1992; importers should verify whether their consignment quantity crosses the notified threshold before filing the bill of entry.
