A word of counsel

The most common error on this tariff line is assuming that CIB&RC registration is the only clearance needed and overlooking the layered CWC and NDPS controls, which are triggered by the precise chemical identity of the imported substance — not by the tariff heading alone. Importers must verify the actual chemical identity against the ITC (HS) Appendix II schedules before filing the bill of entry; a post-arrival discovery that the substance is a Cat IA or Cat IB CWC chemical or a scheduled NDPS substance results in consignment seizure and potential criminal liability under the respective statutes, with no provision for retrospective national-authority permission.

Frequently asked
Does HSN 2921 42 31 require BIS certification?
No, aniline derivatives under this tariff line are not covered by any BIS Quality Control Order. Import is governed by CIB&RC registration and permit under the Insecticides Act, 1968, with concurrent NDPS Rules, 1985 controls and CWC-origin restrictions under the ITC (HS) policy where the specific chemical identity so requires.
Are there port restrictions on importing substances under HSN 2921 42 31?
Yes. Where the imported substance is a scheduled insecticide, import is permitted only at ports notified under Rule 45 of the Insecticides Rules, 1971; the current notified-port list should be confirmed with the CIB&RC Secretariat before placing the purchase order.
What insurance obligation applies where the imported quantity of a hazardous substance exceeds the specified threshold?
On import of specified hazardous substances exceeding prescribed quantities, the owner must take out an insurance policy under the Public Liability Insurance Act, 1991, as notified by S.O. 227(E) dated 24-03-1992 issued by the Ministry of Environment and Forests.
