Compliance steps

1
If the consignment falls within the Schedule to the Insecticides Act, 1968, obtain registration and an import permit from the Secretariat of CIB&RC before shipment. Import of scheduled insecticides is permitted only through the restricted ports notified under Rule 45 of the Insecticides Rules, 1971; unscheduled entries at non-notified ports are liable to seizure.

2
Where the substance meets the NDPS trigger, obtain an import certificate under Rule 53 of the NDPS Rules, 1985 for medical or scientific purposes. For all other NDPS-category imports, comply with Appendix-I to the ITC (HS) Schedule. Upload certificate of analysis (document code 0010dc), batch release certificate (0030dc), label of consignment (0110dc), registration certificate for drugs (101dc1), and import licence for drugs (9111dc) in e-Sanchit before out-of-charge.

A word of counsel

The most common error on this tariff line is treating the CIB&RC and NDPS obligations as mutually exclusive alternatives rather than potentially concurrent requirements. A single consignment of potassium guaiacol sulphonate may simultaneously trigger the Insecticides Act Schedule registration, the NDPS import-certificate regime, and the Chapter 29 mandatory-qualifiers obligation under CBIC Circular 23/2023-Cus — all three must be satisfied before out-of-charge, and failure to upload any of the five e-Sanchit document codes results in detention at the port.

Frequently asked

Does HSN 2909 50 30 require BIS certification?

No. No BIS Quality Control Order covers this ether-phenol sulphonate derivative. Import is governed by CIB&RC registration and permit requirements under the Insecticides Act, 1968, with a concurrent NDPS import-certificate overlay under Rule 53 of the NDPS Rules, 1985, and DGFT ITC (HS) policy condition 2 of Chapter 29.

Which ports are permitted for the import of scheduled insecticides under this tariff line?

Import of insecticides falling in the Schedule to the Insecticides Act, 1968 is restricted to ports notified under Rule 45 of the Insecticides Rules, 1971; the current notified list should be confirmed with CIB&RC before placing the purchase order.

Is an insurance policy required for every consignment of potassium guaiacol sulphonate?

The Public Liability Insurance Act, 1991 obligation is triggered only when specified hazardous substances are imported in quantities exceeding the prescribed thresholds under S.O. 227(E) dated 24-03-1992; consignments below those thresholds are not subject to the insurance requirement.
