Compliance steps
  1. 1
    If the sulphonamide substance 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 shipment. Import of scheduled insecticides is permitted only at the ports specified under Rule 45 of the Insecticides Rules, 1971.
    Insecticides Act, 1968 · Rule 45 of the Insecticides Rules, 1971
  2. 2
    Where the substance is an NDPS-listed compound, obtain an import certificate under Rule 53 of the NDPS Rules, 1985 before the consignment is dispatched. Imports outside the medical and scientific purpose category of Chapter VII-A of the NDPS Rules, 1985 are governed by Appendix-I to the ITC (HS) Schedule per ITC (HS) policy condition 2 to Chapter 29.

A word of counsel

The most common error on this tariff line is treating import as unconditionally free because the ITC (HS) base status is 'free' under DGFT Notification 41/2025-26, while overlooking the three concurrent sub-regime traps: (a) the MIP of ₹1,774 per kg on sulphadiazine API until 30 September 2026, which applies to all importers except AA/EOU/SEZ units — and even for those, only where the input is not sold into the Domestic Tariff Area; (b) the CIB&RC scheduled-pesticide carve-out, which converts what appears to be a free-import organic chemical into a Restricted-regime consignment the moment it falls within the Insecticides Act Schedule; and (c) the NDPS overlay, which imposes a separate certificate regime independent of the CIB&RC and DGFT tracks.

Frequently asked
Does HSN 2935 90 90 require BIS certification?
No. No BIS Quality Control Order covers sulphonamides under this tariff line. Import is governed by the Central Insecticides Board and Registration Committee under the Insecticides Act, 1968, with concurrent NDPS Rules, 1985 and DGFT MIP conditions applying where relevant to the specific substance.
Which document codes must be uploaded in e-Sanchit for sulphonamide drug consignments?
Five documents are mandatory: certificate of analysis for drugs (0010dc), batch release certificate (0030dc), label of consignment (0110dc), registration certificate for drugs (101dc1), and import licence for drugs (9111dc), all per the CCR and CBIC Circular 23/2023-Cus.
Does the MIP exemption for Advance Authorisation holders on sulphadiazine API apply regardless of end-use?
No. The MIP exemption for AA holders, EOUs, and SEZ units is conditional on the imported inputs not being sold into the Domestic Tariff Area; a DTA sale retrospectively attracts the MIP restriction and DGFT-policy enforcement under DGFT Notification 41/2025-26.
