Other derivatives of methane, ethane or propane halogenated only with fluorine and chlorine
Halogenated methane, ethane or propane derivatives (fluorine and chlorine only)
HSN 2903 79 20 covers halogenated derivatives of methane, ethane or propane containing only fluorine and chlorine, and is subject to Central Drugs Standard Control Organisation (CDSCO) registration under G.S.R. 102(E) dated 11-02-2020 where the substance is a listed medical device, and to Central Insecticides Board and Registration Committee (CIB&RC) registration or import permit under the Insecticides Act, 1968 where intended for insecticidal use. Ozone-depleting-substance controls under the Ozone Depleting Substances (Regulation and Control) Rules, 2000, ITC (HS) Restricted-import policy under DGFT Notification 44/2025-26, and mandatory Chapter 29 qualifiers under CBIC Circular 23/2023-Cus apply as additional clearance requirements.
- Registration or import permit from CIB&RC
- CDSCO registration certificate from CDSCO
- Chapter 29 qualifiers from CBIC
Procedural directions for customs clearance are issued by: Directorate General of Foreign Trade, Central Board of Indirect Taxes and Customs.
- 1Determine the intended end-use before filing the bill of entry. If the substance is imported for insecticidal, fungicidal, herbicidal or rodenticidal use, obtain mandatory CIB&RC registration under Section 9 of the Insecticides Act, 1968; if imported for a non-insecticidal purpose, obtain a CIB&RC import permit. Import is restricted to ports specified under Rule 45 of the Insecticides Rules, 1971, and the source of supply must match the certificate of registration or the permit.Insecticides Act, 1968 · Section 9; Rule 45 of the Insecticides Rules, 1971; CBIC Circulars 35/2011-Cus dated 09-08-2011 and 07/2014-Cus dated 07-03-2014
- 2Where the imported substance is a medical device listed in G.S.R. 102(E) dated 11-02-2020 issued by the Ministry of Health and Family Welfare (MOHFW), ensure CDSCO registration is current and all conditions stipulated therein are met before the bill of entry is filed.G.S.R. 102(E) dated 11-02-2020 · MOHFW / CDSCO
- 3File mandatory additional qualifiers for all import declarations under Chapter 29 in compliance with CBIC Circular 23/2023-Cus dated 30-09-2023, effective 15-10-2023. Separately, confirm the consignment is not an ozone-depleting substance subject to Para 8(A) of the ITC (HS) General Notes and the Ozone Depleting Substances (Regulation and Control) Rules, 2000; and confirm compliance with the ITC (HS) Restricted-import policy condition 1 of Chapter 29 under DGFT Notification 44/2025-26 dated 15-10-2025.CBIC Circular 23/2023-Cus dated 30-09-2023 · DGFT Notification 44/2025-26 dated 15-10-2025 · Ozone Depleting Substances (Regulation and Control) Rules, 2000 · Para 8(A) of ITC (HS) General Notes
The single most common error on this tariff line is filing a generic Chapter 29 import declaration without resolving the end-use classification first. The same CFC or HCFC compound may simultaneously trigger CIB&RC registration (insecticidal use), CDSCO registration (medical-device use), ozone-depleting-substance controls, and NDPS policy conditions 2 and 3 — each carrying a distinct document trail. Arriving at the port of entry with only one regime satisfied while the others remain unaddressed results in consignment detention, demurrage, and potential confiscation under the applicable Act.
