Compliance steps

1
Determine whether the specific substance falls within the Schedule to the Insecticides Act, 1968. If so, obtain registration and an import permit from the Secretariat of CIB&RC before shipment; import of scheduled insecticides is restricted to notified ports under Rule 45 of the Insecticides Rules, 1971.

2
If the substance is a scheduled Narcotic Drug or Psychotropic Substance, obtain an import certificate under Rule 53 of the NDPS Rules, 1985 before filing the bill of entry. Imports not qualifying for medical or scientific purposes under Chapter VII-A of the NDPS Rules, 1985 are governed by Appendix-I to the ITC (HS) Schedule.

3
Comply with CBIC Circular 23/2023-Cus dated 30-09-2023 by declaring the mandatory additional qualifiers for Chapter 29 commodities in the import declaration with effect from 15 October 2023. Additionally, where import quantities exceed specified thresholds for hazardous substances, obtain 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 residual tariff line is assuming that only one regulatory track applies. A single substance can simultaneously trigger CIB&RC registration as a scheduled insecticide, NDPS import-certificate requirements, and the public-liability insurance obligation under S.O. 227(E) — each independent of the others. Failing to identify all applicable schedules before filing the bill of entry results in consignment detention and potential confiscation, with no rectification permitted after out-of-charge.

Frequently asked

Does HSN 2904 99 90 require BIS certification?

No, this residual tariff line for sulphonated, nitrated or nitrosated hydrocarbon derivatives is not covered by any BIS Quality Control Order. Import is governed by CIB&RC registration and permit requirements under the Insecticides Act, 1968, NDPS import-certificate requirements under the NDPS Rules, 1985, and DGFT ITC (HS) policy condition 2 of Chapter 29.

Are all substances under HSN 2904 99 90 required to be imported through notified ports?

Port restrictions under Rule 45 of the Insecticides Rules, 1971 apply only where the specific substance is listed in the Schedule to the Insecticides Act, 1968; importers should verify the applicable port list with CIB&RC before placing purchase orders.

When does the public-liability insurance obligation under S.O. 227(E) apply?

The obligation to obtain a public-liability insurance policy arises on import of specified hazardous substances exceeding the quantities prescribed under S.O. 227(E) dated 24-03-1992 issued by the Ministry of Environment and Forests; the threshold quantities are listed in that notification.
