Compliance steps

1
Obtain a valid Certificate of Registration from the Central Insecticides Board and Registration Committee under Section 9 of the Insecticides Act, 1968 before the consignment is shipped. Where import is for a non-insecticidal purpose, obtain an import permit from the Registration Committee; the permit or certificate must specify the approved source of supply, and import from any other source is not permitted.

2
Route the consignment through a port at which insecticide imports are permitted under Rule 45 of the Insecticides Rules, 1971. Consignments arriving at a non-notified port are liable to detention and enforcement action under the Insecticides Act, 1968.

A word of counsel

The dual-track registration regime is the most common trap on this tariff line: importers using mercurous chloride for laboratory or industrial purposes assume the insecticidal-use registration held by another entity covers their shipment, only to find that a non-insecticidal-purpose import permit is separately required. The Registration Committee specifies the approved source on both the certificate and the permit — a change of supplier without a corresponding amendment renders the import unlawful regardless of whether the substance itself is otherwise registered, and consignment seizure under the Insecticides Act, 1968 follows.

Frequently asked

Does HSN 2827 39 20 require BIS certification?

No, mercurous chloride is not covered by any BIS Quality Control Order. Import is governed by the Central Insecticides Board and Registration Committee under Section 9 of the Insecticides Act, 1968, with a concurrent CBIC Chapter 28 declaration-qualifier requirement effective 15 October 2023.

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

Import is restricted to ports notified under Rule 45 of the Insecticides Rules, 1971; the current notified-port list should be confirmed with CIB&RC before vessel departure, as arrival at a non-notified port triggers detention irrespective of registration status.

Does the source-of-supply restriction on the registration certificate apply even when the substance is imported for non-insecticidal use?

Yes. Both the Certificate of Registration and the import permit issued by the Registration Committee specify the approved source, and import from any other source — regardless of end-use — is prohibited under the Insecticides Act, 1968.
