Compliance steps

1
Determine whether the specific substance or formulation falls within the Schedule to the Insecticides Act, 1968. If so, obtain registration and an import permit from the Secretariat of the Central Insecticides Board and Registration Committee before shipment, and route the consignment only through ports permitted under Rule 45 of the Insecticides Rules, 1971.

Where the substance qualifies as an NDPS substance, obtain an import certificate under Rule 53 of the NDPS Rules, 1985 for imports made under the special provisions for medical and scientific purposes (Chapter VII-A of the NDPS Rules, 1985). Imports outside that category are governed by Appendix-I to the ITC (HS) Schedule.

A word of counsel

The most common error on this tariff line is filing the bill of entry without first determining whether the specific substance falls within the Schedule to the Insecticides Act, 1968 — a classification exercise that must precede shipment, not follow it. If the substance is Scheduled, the CIB&RC import permit governs the permitted port of import under Rule 45 of the Insecticides Rules, 1971; shipping through an unpermitted port exposes the consignment to seizure and confiscation independently of any NDPS or DGFT non-compliance.

Frequently asked

Does HSN 2917 36 00 require BIS certification?

No, terephthalic acid and its salts are not covered by any BIS Quality Control Order. Import is governed by the Central Insecticides Board and Registration Committee under the Insecticides Act, 1968 where the substance is Scheduled, with concurrent NDPS Rules, 1985 conditions and DGFT ITC (HS) policy condition 2 to Chapter 29.

Which ports are permitted for import of Scheduled insecticides under this tariff line?

Ports at which insecticides may be imported are restricted under Rule 45 of the Insecticides Rules, 1971; the permitted list must be confirmed with CIB&RC before vessel departure, as routing to an unpermitted port renders the consignment liable to seizure.

When does the NDPS import-certificate requirement apply, and what governs imports outside the medical and scientific category?

An import certificate under Rule 53 of the NDPS Rules, 1985 is required for substances imported under Chapter VII-A special provisions for medical and scientific purposes; all other NDPS-category imports are governed by Appendix-I to the ITC (HS) Schedule under policy condition 2 to Chapter 29.
