Amino pyridine

Aminopyridine, heterocyclic organic chemical (pyridine derivative)

CIB&RC CLEARANCE · NDPS CLEARANCE

HSN 2933 39 11 (Amino pyridine) is subject to dual primary regulation: the Central Insecticides Board and Registration Committee (CIB&RC) requires registration and an import permit where the substance figures in the Schedule to the Insecticides Act, 1968, and the Narcotic Drugs and Psychotropic Substances (NDPS) regime applies where the substance falls within the NDPS Rules, 1985. The Directorate General of Foreign Trade (DGFT) ITC (HS) policy condition 2 of Chapter 29 governs non-medical/scientific NDPS imports, and the Central Board of Indirect Taxes and Customs (CBIC) mandates Chapter 29 additional qualifiers under CBIC Circular 23/2023-Cus dated 30-09-2023.

Compliance steps

1
Determine whether the aminopyridine variant being imported is listed in 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 before filing the bill of entry; note that places of import are restricted under Rule 45 of the Insecticides Rules, 1971.

2
Where the substance qualifies under the NDPS regime, import for medical and scientific purposes requires an import certificate under Rule 53 of the NDPS Rules, 1985 (Chapter VII-A). All other NDPS imports are governed by Appendix I to the ITC (HS) Schedule; ensure the applicable document codes — certificate of analysis (0010dc), batch release certificate (0030dc), label of consignment (0110dc), registration certificate for drugs (101dc1), and import licence for drugs (9111dc) — are uploaded in e-Sanchit before out-of-charge.

3
Ensure all import declarations include the 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, where import quantities exceed the thresholds under the Public Liability Insurance Act, 1991, obtain the required insurance policy per S.O. 227(E) dated 24-03-1992.

A word of counsel

The most common error on this tariff line is treating the CIB&RC and NDPS tracks as mutually exclusive — aminopyridine may simultaneously trigger a CIB&RC scheduled-substance registration requirement and NDPS import-certificate obligations depending on the specific isomer and end use. Importers who clear the CIB&RC permit but omit the NDPS import certificate under Rule 53, or vice versa, face consignment detention and potential seizure under the NDPS Act, 1985 even where all other documents are in order.

Frequently asked

Does HSN 2933 39 11 require BIS certification?

No. No BIS Quality Control Order covers this product family. Import of aminopyridine is governed by the Central Insecticides Board and Registration Committee under the Insecticides Act, 1968 where the substance is scheduled, and by the NDPS Rules, 1985 where the substance falls within the NDPS regime, with DGFT ITC (HS) policy condition 2 of Chapter 29 as the overlying policy framework.

Are the ports of import restricted for this tariff line?

Yes. Where the substance is listed in the Schedule to the Insecticides Act, 1968, the places at which it may be imported are restricted under Rule 45 of the Insecticides Rules, 1971; importers must confirm the designated entry points with the CIB&RC Secretariat before vessel departure.

What happens if the consignment value or quantity exceeds the Public Liability Insurance threshold?

Import of specified hazardous substances exceeding the notified quantities triggers a mandatory insurance-policy requirement under the Public Liability Insurance Act, 1991, as detailed in S.O. 227(E) dated 24-03-1992; failure to hold the required policy exposes the owner to separate statutory liability independent of the CIB&RC and NDPS clearances.
