O-phenylenediamine
O-phenylenediamine, an aromatic diamine organic chemical
HSN 2921 51 10 (O-phenylenediamine) is covered by a Bureau of Indian Standards Quality Control Order. Conformity to IS 17450:2020 is mandatory under the ISI Mark Scheme with effect from 28 October 2022, by virtue of the 1,3 Phenylenediamine (Quality Control) Order, 2022. Narcotic Drugs and Psychotropic Substances controls, Chemical Weapons Convention restrictions, insecticide registration requirements, and Public Liability Insurance obligations apply as separate customs-clearance overlays.
Procedural directions for customs clearance are issued by: Central Board of Indirect Taxes and Customs, Directorate General of Foreign Trade.
- 1Source only from a Bureau of Indian Standards CM/L-licensed manufacturer holding a current licence against IS 17450:2020. Verify the supplier's CM/L number, licensed product scope, and manufacturing facility on the BIS online register before placing the purchase order.1,3 Phenylenediamine (Quality Control) Order, 2022 · S.O. 1960(E) dated 27-04-2022
- 2Ensure the consignment bears the ISI mark and the supplier's CM/L number as required under Scheme-I of Schedule-II to the BIS (Conformity Assessment) Regulations, 2018. Marking must appear on the product label, not on outer packaging alone.Scheme-I of Schedule-II to the BIS (Conformity Assessment) Regulations, 2018 · S.O. 1960(E) dated 27-04-2022
- 3Determine whether the consignment contains any substance listed under the Narcotic Drugs and Psychotropic Substances Rules, 1985. If so, obtain an import certificate under Rule 53 of the NDPS Rules before shipment; imports outside the medical and scientific purpose category are governed by Appendix I to the ITC (HS) Schedule.Chapter VII-A of the NDPS Rules, 1985 · Rule 53 of the NDPS Rules · ITC (HS) policy condition 2 to Chapter 29
- 4Confirm that the product does not fall within the schedule to the Insecticides Act, 1968. If it does, obtain registration and a permit from the secretariat of the Central Insecticides Board and Registration Committee; note that places of import for scheduled insecticides are restricted under Rule 45 of the Insecticides Rules, 1971.Insecticides Act, 1968 · Rule 45 of the Insecticides Rules, 1971
- 5Include mandatory additional qualifiers in the import declaration as required by CBIC Circular 23/2023-Cus dated 30-09-2023 for Chapter 29 commodities, effective 15 October 2023. Upload all mandatory e-Sanchit documents — certificate of analysis, batch release certificate, consignment label, registration certificate, and import licence — before requesting out-of-charge.CBIC Circular 23/2023-CUS dated 30-09-2023 · ITC (HS) policy · S.O. 227(E) dated 24-03-1992
The single most common error on this tariff line is obtaining BIS CM/L compliance against IS 17450:2020 while overlooking the concurrent multi-agency gatekeeping that customs applies independently. The CCR triggers separate verification queues for NDPS controls, Chemical Weapons Convention restrictions, insecticide-schedule status, and Public Liability Insurance under S.O. 227(E) — any one of these being absent or unresolved holds the consignment regardless of a clean BIS CM/L. Map every applicable overlay before shipment, not at the port.
