A word of counsel

The most common error on this tariff line is assuming the CIB&RC import permit is the sole clearance required and overlooking the concurrent NDPS Rules, 1985 overlay: if DNOC or any of its salts is scheduled under the NDPS framework, an import certificate under Rule 53 of the NDPS Rules, 1985 is required separately, and imports outside the medical and scientific purposes category are governed by Appendix-I to the ITC (HS) Schedule. A consignment cleared for insecticide purposes but carrying a quantity triggering the NDPS scheduled threshold will be detained, and no rectification at the port-of-import stage substitutes for the advance import certificate.

Frequently asked

Does HSN 2908 92 00 require BIS certification?

No, no BIS Quality Control Order covers this product family. Import of 4,6-Dinitro-o-cresol and its salts is governed by the Central Insecticides Board and Registration Committee under the Insecticides Act, 1968, with a concurrent NDPS Rules, 1985 overlay where the substance is scheduled.

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

Rule 45 of the Insecticides Rules, 1971 restricts import to specified places; the current approved port list is maintained by CIB&RC and must be confirmed before placing the purchase order, as diversion to an unspecified port renders the consignment liable to seizure.

When does the NDPS import certificate requirement under Rule 53 apply to this HSN?

Where DNOC or its salts fall within a category scheduled under the NDPS framework, an import certificate under Rule 53 of the NDPS Rules, 1985 is required for medical and scientific purposes imports; all other imports in that category are governed by Appendix-I to the ITC (HS) Schedule per ITC (HS) policy condition 2 of Chapter 29.
