Compliance steps

1
Obtain registration and an import permit from the Secretariat of the Central Insecticides Board and Registration Committee before filing the bill of entry, where the substance falls within the Schedule to the Insecticides Act, 1968. Import is restricted to notified places — confirm the port of entry is a permitted place under Rule 45 of the Insecticides Rules, 1971.

2
If the consignment involves NDPS-scheduled substances, obtain an import certificate under Rule 53 of the NDPS Rules, 1985 for medical and scientific purposes, or comply with Appendix I to the ITC (HS) Schedule for other purposes. Verify CWC status: nitrogen mustards require national authority permission (Appendix II, Schedule I, Category 1A), and certain N,N-dialkyl aminoethyl-2-chlorides are permitted only from States Parties to the CWC (Category 1B).

A word of counsel

The most common error on this tariff line is treating CIB&RC registration as the sole hurdle and overlooking the layered CWC and NDPS controls, which operate independently and can render an otherwise-licensed import unlawful at the bill-of-entry stage. A consignment of N,N-dimethyl toluidine may clear CIB&RC scrutiny yet be detained if the origin country is not a State Party to the CWC for a restricted chemical category, or if the importer has not obtained the Rule 53 import certificate where NDPS scheduling applies. Verify each overlay before vessel loading.

Frequently asked

Does HSN 2921 43 20 require BIS certification?

No, N,N-dimethyl toluidine is not subject to any BIS Quality Control Order. Import is governed by the Central Insecticides Board and Registration Committee under the Insecticides Act, 1968, with concurrent NDPS, CWC, and DGFT policy controls applying under ITC (HS) policy condition 2 to Chapter 29.

Are all ports permitted for import of insecticide-scheduled substances under this tariff line?

No. Rule 45 of the Insecticides Rules, 1971 restricts import of scheduled insecticide substances to notified places only; importing through an unpermitted port renders the consignment liable to seizure under the Insecticides Act, 1968.

When does the CWC national authority permission apply to this HSN?

Permission from the national authority is required where the imported substance qualifies as a nitrogen mustard under Category 1A of Appendix II to Schedule I of the ITC (HS) policy; N,N-dialkyl aminoethyl-2-chloride variants under Category 1B are additionally restricted to imports from States Parties to the Chemical Weapons Convention.
