H acid
H acid, aminohydroxynaphthalene sulphonic acid
HSN 2922 21 60 (H acid) is subject to registration and import permit requirements administered by the Central Insecticides Board and Registration Committee (CIB&RC) under the Insecticides Act, 1968, where the substance figures in the Schedule to that Act, with import restricted to notified places under Rule 45 of the Insecticides Rules, 1971. Narcotic Drugs and Psychotropic Substances (NDPS) controls apply as a concurrent overlay, and the Directorate General of Foreign Trade (DGFT) ITC (HS) policy condition 2 of Chapter 29 governs imports outside the medical and scientific purposes regime.
- Registration certificate from CIB&RC
- Import permit from CIB&RC
- Import certificate from NDPS
Procedural directions for customs clearance are issued by: Directorate General of Foreign Trade, Central Board of Indirect Taxes and Customs.
- 1Where H acid falls within the Schedule to the Insecticides Act, 1968, obtain registration and an import permit from the secretariat of the Central Insecticides Board and Registration Committee before filing the bill of entry. Route the consignment only through places notified under Rule 45 of the Insecticides Rules, 1971; diversion to an unnotified port or location renders the import unauthorised under the Act.Insecticides Act, 1968 · Rule 45 of the Insecticides Rules, 1971 · ITC (HS) policy condition 2 of Chapter 29
- 2Where the substance is subject to NDPS controls, import for medical and scientific purposes requires an import certificate under Rule 53 of the NDPS Rules, 1985 per Chapter VII-A of those Rules. Imports outside this category are governed by Appendix I to the ITC (HS) Schedule; reference the Central Bureau of Narcotics at cbn.nic.in for the applicable procedure.Rule 53 of the NDPS Rules, 1985 · Chapter VII-A of the NDPS Rules, 1985 · ITC (HS) policy condition 2 of Chapter 29
- 3Ensure the import declaration includes mandatory additional qualifiers for Chapter 29 commodities as stipulated in paragraphs 4.1 and 4.2 of CBIC Circular 23/2023-Cus dated 30-09-2023, with effect from 15 October 2023. Additionally, where import of the specified hazardous substance exceeds the quantities prescribed under S.O. 227(E) dated 24-03-1992, take out the required insurance policy under the Public Liability Insurance Act, 1991.CBIC Circular 23/2023-Cus dated 30-09-2023 · S.O. 227(E) dated 24-03-1992 · Public Liability Insurance Act, 1991
The most common error on this tariff line is failing to determine at the pre-import stage whether H acid's specific formulation or end-use places it within the Schedule to the Insecticides Act, 1968 — a classification that is product-specific and cannot be assumed in either direction. An importer who proceeds without CIB&RC registration and permit on a scheduled substance faces consignment detention, seizure, and prosecution under the Insecticides Act, 1968, with the dual NDPS overlay creating a separate and independent liability track if the substance is also a controlled precursor.
