Carboxylic acids with aldehyde or ketone function, other derivatives
HSN 2918 30 90 (carboxylic acids with aldehyde or ketone function, residual category) is subject to Central Insecticides Board and Registration Committee (CIB&RC) registration and import permit under the Insecticides Act, 1968 where constituent substances appear in its Schedule, and to Narcotic Drugs and Psychotropic Substances (NDPS) controls for scheduled substances such as methyl alpha-phenylacetoacetate (MAPA) under the NDPS (Regulation of Controlled Substances) Amendment Order, 2020. The Directorate General of Foreign Trade (DGFT) ITC (HS) policy condition no. 08 of Chapter 29 applies until 30 November 2026, and mandatory Chapter 29 qualifiers in import declarations are required under Central Board of Indirect Taxes and Customs (CBIC) Circular 23/2023-Cus.

- 1Determine whether the specific substance being imported appears in the Schedule to the Insecticides Act, 1968. If so, obtain registration and an import permit from the Secretariat of the Central Insecticides Board and Registration Committee, and route the consignment only through ports notified under Rule 45 of the Insecticides Rules, 1971.Insecticides Act, 1968 · Rule 45 of the Insecticides Rules, 1971
- 2If the substance is a controlled substance under the NDPS regime — including MAPA and its optical isomers — obtain a No Objection Certificate from the Narcotics Commissioner before shipment. Imports for medical and scientific purposes require an import certificate under Rule 53 of the NDPS Rules, 1985; all other imports are governed by Appendix I to the ITC (HS) Schedule per policy condition no. 2 of Chapter 29.NDPS (Regulation of Controlled Substances) Amendment Order, 2020 [G.S.R. 536(E) dated 26-08-2020] · Rule 53 of the NDPS Rules, 1985 · ITC (HS) policy condition no. 2 of Chapter 29
- 3File the bill of entry with mandatory additional qualifiers for Chapter 29 commodities as stipulated in paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus, effective 15 October 2023. Additionally, verify that imports of 2,2-diphenyl-2-hydroxyacetic acid and benzeneacetic acid alpha-hydroxy-alpha-phenyl originate exclusively from State Parties to the Chemical Weapons Convention, as required by Appendix II to Schedule I (Category IB) of the ITC (HS) policy.CBIC Circular 23/2023-Cus dated 30-09-2023 · ITC (HS) policy Appendix II to Schedule I (Category IB) · DGFT Notification 50/2025-26 dated 18-12-2025
The critical trap on this residual tariff line is its multi-regime overlay: the CIB&RC, NDPS, and ITC (HS) CWC-origin controls each apply to different substance subsets within the same 8-digit code, and none displaces the others. Importers who secure CIB&RC clearance but overlook the NDPS NOC — or who misread the CWC-origin restriction as procedural rather than prohibitive — face consignment detention and potential seizure at the port. Confirm the regulatory identity of each specific substance before placing the purchase order, not at the bill-of-entry stage.
