Compliance steps

1
Determine whether the specific chlorodifluoroethane product falls within the Schedule to the Insecticides Act, 1968. If scheduled, obtain registration and an import permit from the Secretariat of the Central Insecticides Board and Registration Committee, and route the consignment only through ports permitted under Rule 45 of the Insecticides Rules, 1971.

2
If the substance is classified under the NDPS framework, import under the special provisions for medical and scientific purposes requires an import certificate under Rule 53 of the NDPS Rules, 1985. Imports outside that category are governed by Appendix-I to the ITC (HS) Schedule per ITC (HS) policy condition 2 of Chapter 29.

Ensure mandatory additional qualifiers are declared in the import declaration for all Chapter 29 commodities in compliance with CBIC Circular 23/2023-Cus dated 30-09-2023, paragraphs 4.1 and 4.2, with effect from 15-10-2023. Where import of specified hazardous substances exceeds the specified quantities, take out an insurance policy under the Public Liability Insurance Act, 1991 as per S.O. 227(E) dated 24-03-1992.

A word of counsel

The most common error on this tariff line is treating the ITC (HS) Restricted status as the only compliance hurdle and overlooking the dual-layer PGA trigger: whether the specific HCFC-142/142b formulation is scheduled under the Insecticides Act, 1968 must be determined before shipment, since that determination controls both the CIB&RC permit requirement and the permitted ports of import under Rule 45 of the Insecticides Rules, 1971. Arriving at a non-permitted port without the CIB&RC import permit will result in detention regardless of DGFT policy-condition compliance.
