Compliance steps

1
Obtain a CIB&RC Certificate of Registration under Section 9 of the Insecticides Act, 1968 before shipping. Where the substance is imported for a non-insecticidal purpose, obtain an import permit from the Registration Committee under the Department of Agriculture and Cooperation; no import may originate from a source not specified on the certificate or permit.

A word of counsel

The most frequent error on this residual tariff line is assuming that a non-insecticidal end-use exempts the importer from CIB&RC formalities altogether. It does not: a non-insecticidal import still requires an import permit from the Registration Committee, and that permit must specify the approved source — a change of supplier or country of origin without a fresh permit triggers detention and potential confiscation under the Insecticides Act, 1968, even where the substance's end-use is entirely industrial.

Frequently asked

Does HSN 2811 19 90 require BIS certification?

No, this residual inorganic-acids tariff line 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 mandatory Chapter 28 qualifier declarations under CBIC Circular 23/2023-Cus at the bill-of-entry stage.

Does the CIB&RC registration permit import from any supplier, or is the source restricted?

The source is restricted: the Certificate of Registration or import permit issued by the Registration Committee specifies the approved country and facility of origin, and import from any other source is prohibited under the Insecticides Act, 1968.

When does the Public Liability Insurance requirement apply to this HSN?

The PLI policy requirement under the Public Liability Insurance Act, 1991 is triggered when the imported hazardous substance is imported in quantities exceeding the thresholds specified in S.O. 227(E) dated 24-03-1992; importers must confirm whether their consignment volume crosses those thresholds before filing the bill of entry.
