A word of counsel

The most common error on this tariff line is treating hexamine as a straightforward organic chemical and overlooking the dual-regime trap: the CIB&RC pesticide-schedule check and the NDPS/CWC policy overlay operate independently, and a consignment that clears one regime may still be detained if the other has not been addressed. Additionally, the mandatory Chapter 29 qualifier obligation under CBIC Circular 23/2023-Cus — effective 15 October 2023 — is a distinct bill-of-entry obligation; failure to include the stipulated qualifiers triggers detention irrespective of whether PGA clearances are in order.

Frequently asked

Does HSN 2921 29 10 require BIS certification?

No, hexamethylene tetramine under this tariff line is not within the BIS Quality Control Order regime. Import is governed by the Central Insecticides Board and Registration Committee under the Insecticides Act, 1968, with concurrent NDPS Rules, 1985 conditions and CWC-based ITC (HS) policy controls administered by DGFT.

Are all imports of hexamine under this CTI required to obtain CIB&RC registration and a permit?

Only where hexamine figures in the Schedule to the Insecticides Act, 1968; where it does, registration and an import permit from CIB&RC are mandatory and import is restricted to ports specified under Rule 45 of the Insecticides Rules, 1971.

What happens if hexamine is imported for medical or scientific purposes and an NDPS condition applies?

Import for medical and scientific purposes is permitted under Chapter VII-A of the NDPS Rules, 1985 after obtaining an import certificate under Rule 53; imports falling outside that category are governed by Appendix I to the ITC (HS) Schedule under policy condition 2 of Chapter 29.
