Compliance steps
  1. 1
    Obtain registration and an import permit from the Secretariat of the Central Insecticides Board and Registration Committee before filing the bill of entry, if the substance figures in the Schedule to the Insecticides Act, 1968. Route the consignment only through a place of import designated under Rule 45 of the Insecticides Rules, 1971; diversion to an undesignated port renders the consignment liable to seizure.

  2. 2
    Where the substance is imported for medical or scientific purposes under Chapter VII-A of the NDPS Rules, 1985, obtain an import certificate under Rule 53 of the NDPS Rules before shipment. Imports outside this category are governed by Appendix I to the ITC (HS) Schedule per ITC (HS) policy condition 2 of Chapter 29.

A word of counsel

The most frequent error on this tariff line is treating the CIB&RC registration as the sole gateway while overlooking the independent NDPS import-certificate requirement: where methylphosphonic dichloride is also classifiable as a scheduled NDPS substance, both a CIB&RC import permit and an NDPS Rule 53 import certificate are required concurrently, and the absence of either triggers detention and potential confiscation. Additionally, importers who ship through a non-designated port under Rule 45 of the Insecticides Rules, 1971 face seizure regardless of whether all other licences are current.

Frequently asked
Does HSN 2931 51 00 require BIS certification?
No, methylphosphonic dichloride 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, with a concurrent NDPS import-certificate requirement under Rule 53 of the NDPS Rules, 1985, and an ITC (HS) Restricted-import policy overlay administered by DGFT.
Are there designated port restrictions for importing methylphosphonic dichloride?
Yes. Rule 45 of the Insecticides Rules, 1971 restricts import of scheduled insecticides to notified places of import only; shipment through any non-designated port renders the consignment liable to seizure regardless of licence validity.
Does the Public Liability Insurance Act, 1991 apply to imports of this substance?
Yes. Where the substance qualifies as a specified hazardous substance imported in quantities exceeding the prescribed threshold, the owner is required to take out an insurance policy under the Public Liability Insurance Act, 1991, as notified by S.O. 227(E) dated 24-03-1992 by the Ministry of Environment and Forests.
