CIB&RC CLEARANCE · NDPS CLEARANCE

Compliance steps

1
Where dicyandiamide is listed in 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.

2
If the substance falls within the NDPS framework, import is permitted only for medical or scientific purposes under Chapter VII-A of the NDPS Rules, 1985 with an import certificate obtained under Rule 53 of the NDPS Rules; consignments outside that category are governed by Appendix-I to the ITC (HS) Schedule. Upload mandatory e-Sanchit documents — certificate of analysis (0010dc), batch release certificate (0030dc), label of consignment (0110dc), registration certificate for drugs (101dc1), and import licence for drugs (9111dc) — before out-of-charge.

Additionally, if import exceeds specified hazardous-substance thresholds, take out a public liability insurance policy under S.O. 227(E) dated 24-03-1992.

A word of counsel

The most frequent error on this tariff line is assuming that either the CIB&RC registration or the NDPS import certificate alone provides sufficient clearance, when both regimes may apply simultaneously depending on end-use. A consignment cleared under the NDPS medical-and-scientific-purposes carve-out but lacking CIB&RC registration — where the substance is Scheduled under the Insecticides Act, 1968 — will be detained at the designated port of import; the two licences are not interchangeable, and the Chapter 29 mandatory qualifiers under CBIC Circular 23/2023-Cus are required regardless of which PGA track governs.
