Substances on this page imported for industrial use

Import requirements

The documents required with Form IA, the 30% quantity rule and the six stages of the application are set out in the import permit procedure and the document checklist. Consignments are released by customs only against a permit valid on the date of import and naming the source of supply.

Frequently asked questions

Which substances beginning with T require an import permit?

All 109 entries listed on this page are substances in the Schedule to the Insecticides Act, 1968. Import of any of them for a non-insecticidal, industrial purpose requires an import permit on Form IA from the Registration Committee of CIB&RC.

What is the government fee and the decision timeline?

The government fee prescribed with Form IA is ₹5,000 per application, payable to the authority. A complete application is to be decided preferably within 45 days, extendable by up to 15 days.

How is a substance traded under a brand name identified?

By its active ingredient, as stated in the material safety data sheet. Where the active ingredient appears in the Schedule, the preparation is regulated accordingly.
