Compliance steps

1
Verify whether the substance is scheduled under 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. Import is additionally restricted to ports notified under Rule 45 of the Insecticides Rules, 1971 — confirm the port of entry is on the permitted list before vessel departure.

A word of counsel

The most common error on this tariff line is assuming that because the substance is an organophosphonate ester — not a conventional agrochemical — it escapes the Insecticides Act, 1968 schedule. The CIB&RC schedule is substance-specific, not use-specific: if the compound is listed, registration and the restricted-port requirement under Rule 45 of the Insecticides Rules, 1971 apply regardless of the importer's intended end use. Confirming schedule status before the purchase order is placed avoids consignment detention at a non-notified port.

Frequently asked

Does HSN 2931 47 00 require BIS certification?

No, this organo-inorganic compound is 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 a concurrent NDPS overlay under Rule 53 of the NDPS Rules, 1985 and DGFT ITC (HS) Appendix-II policy conditions.

At which ports may this substance be imported if it falls under the Insecticides Act schedule?

Import of scheduled insecticides is restricted to ports specifically notified for that purpose under Rule 45 of the Insecticides Rules, 1971; the current notified list should be confirmed with the CIB&RC secretariat before booking the shipment.

Does the ITC (HS) Appendix-II policy condition apply automatically, or only where the substance is explicitly listed?

The CCR directs importers to verify Appendix-II inclusion and ensure compliance before clearance; the classification is substance-specific, so the importer must confirm the compound's listing status against Appendix-II of the ITC (HS) import policy before filing the bill of entry.
