Compliance steps
  1. 1
    Verify whether Diethyl ethylphosphonate figures in the Schedule to the Insecticides Act, 1968. If it does, obtain registration and an import permit from the Secretariat of the Central Insecticides Board and Registration Committee, and route the consignment only through places notified under Rule 45 of the Insecticides Rules, 1971.
    Insecticides Act, 1968 · Rule 45 of the Insecticides Rules, 1971
  2. 2
    Check whether the consignment triggers NDPS conditions under ITC (HS) policy condition 2 to Chapter 29. If it qualifies as an NDPS substance for medical or scientific purposes, obtain an import certificate under Rule 53 of the NDPS Rules, 1985; other NDPS-classified imports are governed by Appendix-I of the ITC (HS) Schedule.
    Chapter VII-A and Rule 53 of the NDPS Rules, 1985 · ITC (HS) policy condition 2 to Chapter 29
  3. 3
    Ensure compliance with Appendix-II of the ITC (HS) import policy before clearance, and include all mandatory additional qualifiers in the import declaration as stipulated in paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus dated 30-09-2023, applicable to Chapter 29 commodities with effect from 15-10-2023. Where the quantity of specified hazardous substances exceeds the specified threshold, obtain an insurance policy under the Public Liability Insurance Act, 1991 per S.O. 227(E) dated 24-03-1992.

A word of counsel

The most common error on this tariff line is treating the CIB&RC and NDPS tracks as mutually exclusive: a single consignment of Diethyl ethylphosphonate can simultaneously attract insecticide-schedule registration requirements, NDPS import-certificate conditions, and Appendix-II ITC (HS) policy controls. Importers who clear only one regulatory track and overlook the others risk detention, seizure, and parallel enforcement actions under both the Insecticides Act, 1968 and the NDPS Act, 1985. Confirm applicability of each track against the consignment's end-use and concentration before the bill of entry is filed.

Frequently asked
Does HSN 2931 43 00 require BIS certification?
No. No BIS Quality Control Order covers Diethyl ethylphosphonate or this organo-phosphorus product family. Import is governed by CIB&RC registration and permit under the Insecticides Act, 1968, with NDPS and DGFT Appendix-II ITC (HS) policy overlays as applicable.
Are the mandatory Chapter 29 qualifiers in the import declaration required for every shipment?
Yes. CBIC Circular 23/2023-Cus dated 30-09-2023 mandates additional qualifiers in import declarations for all Chapter 29 commodities per paragraphs 4.1 and 4.2, with effect from 15-10-2023; omission at the bill-of-entry stage causes mismatch queries and potential detention.
Can Diethyl ethylphosphonate be imported for medical or scientific purposes without full NDPS Schedule-I controls?
Yes, but only after obtaining a valid import certificate under Rule 53 of the NDPS Rules, 1985 through the special provision in Chapter VII-A; imports that do not qualify under that category are governed by Appendix-I of the ITC (HS) Schedule and attract the full restricted-import regime.
