Where the consignment is imported for medical or scientific purposes under the NDPS overlay, obtain an import certificate under Rule 53 of the NDPS Rules, 1985 as required by Chapter VII-A of those Rules. Imports outside that category are governed by Appendix-I to the ITC (HS) Schedule under ITC (HS) policy condition no. 2 of Chapter 29.

Comply with CBIC Circular 23/2023-Cus dated 30-09-2023, which mandates additional qualifiers in the import declaration for Chapter 29 commodities with effect from 15-10-2023. Additionally, where the imported quantity of the specified hazardous substance exceeds prescribed thresholds, take out 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 tariff line is assuming that because styrene is primarily an industrial petrochemical solvent, the CIB&RC and NDPS overlays are inapplicable. The Schedule to the Insecticides Act, 1968 must be checked against the specific grade and formulation being imported; a Schedule-listed substance imported without CIB&RC registration and permit is liable to seizure at the notified port, and a missing Chapter 29 CBIC qualifier declaration triggers bill-of-entry rejection at the gate.

Frequently asked

Does HSN 2902 50 00 require BIS certification?

No. Styrene is not covered by any BIS Quality Control Order; no BIS QCO applies to this cyclic hydrocarbon. Import is governed by CIB&RC registration and permit under the Insecticides Act, 1968 where the substance is Schedule-listed, with an NDPS Rules overlay for medical or scientific import purposes.

Are all import locations permitted for styrene, or does the port restriction apply?

Import locations are restricted under Rule 45 of the Insecticides Rules, 1971 where the substance falls within the Schedule to the Insecticides Act, 1968; consignments must be routed through notified places only.

When does the NDPS import-certificate requirement apply to this tariff line?

The NDPS import certificate under Rule 53 of the NDPS Rules, 1985 is required only for medical or scientific purpose imports under Chapter VII-A of those Rules; all other imports are instead governed by Appendix-I to the ITC (HS) Schedule under policy condition no. 2 of Chapter 29.
