1,4/1,3/2,3-butylene glycol
Butylene glycol isomers (1,4-, 1,3-, 2,3-butanediol)
HSN 2905 39 10 (1,4/1,3/2,3-butylene glycol) is subject to Central Insecticides Board and Registration Committee (CIB&RC) registration and import permit under the Insecticides Act, 1968, where the substance figures in the Schedule to that Act. Imports carrying a narcotic or psychotropic character are additionally governed by the Narcotic Drugs and Psychotropic Substances (NDPS) Rules, 1985, and the Directorate General of Foreign Trade (DGFT) ITC (HS) policy condition 2 of Chapter 29 applies as a parallel overlay. Mandatory Chapter 29 qualifiers in the import declaration are required under CBIC Circular 23/2023-Cus dated 30-09-2023.

- 1Determine whether the specific butylene glycol isomer being imported 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 ensure import is conducted only through ports notified under Rule 45 of the Insecticides Rules, 1971.Insecticides Act, 1968 · Rule 45 of the Insecticides Rules, 1971 · ITC (HS) policy condition 2 of Chapter 29
- 2If the substance is classified under the NDPS framework, obtain an import certificate under Rule 53 of the NDPS Rules, 1985 for medical and scientific purposes; imports outside that category are governed by Appendix-I to the ITC (HS) Schedule. Confirm the applicable category before filing the bill of entry.Chapter VII-A and Rule 53 of the NDPS Rules, 1985 · ITC (HS) policy condition 2 of Chapter 29
- 3Include all mandatory additional qualifiers in the import declaration as stipulated under paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus, applicable to Chapter 29 commodities with effect from 15 October 2023. Where import quantities of specified hazardous substances exceed prescribed thresholds, take out a public liability insurance policy per S.O. 227(E) dated 24-03-1992.CBIC Circular 23/2023-Cus dated 30-09-2023 · S.O. 227(E) dated 24-03-1992
The most common error on this tariff line is treating butylene glycol as a plain industrial chemical and overlooking the dual-trigger structure: the CIB&RC Schedule check and the NDPS Schedule check are independent inquiries, and a consignment may engage one, both, or neither depending on its composition and end-use declaration. Importers who file without confirming Schedule status face consignment detention at the notified port and potential seizure under the Insecticides Act, 1968 or the NDPS Act, 1985 — neither of which permits post-arrival rectification of a missing permit.
