Compliance steps

1
Where sodium naphthionate figures 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 filing the bill of entry. Import is restricted to notified places of import under Rule 45 of the Insecticides Rules, 1971; routing through any non-notified port attracts detention and enforcement under the Act.

2
If the consignment is classified as an NDPS substance, obtain an import certificate under Rule 53 of the NDPS Rules, 1985 from the Central Bureau of Narcotics (cbn.nic.in) before shipment. Imports for purposes other than medical and scientific use 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 importing on the assumption that neither the CIB&RC schedule nor the NDPS regime applies to sodium naphthionate, and discovering at the port of entry that the substance has been flagged under one or both frameworks. Both triggers are product-specific and require pre-shipment verification against the current Schedule to the Insecticides Act, 1968 and the NDPS Rules, 1985 schedules; a consignment that arrives without the applicable permit or import certificate faces detention, demurrage, and potential confiscation with no rectification pathway at the port.

Frequently asked

Does HSN 2921 45 16 require BIS certification?

No; no BIS Quality Control Order covers naphthylamine derivatives or their salts. Import of sodium naphthionate is governed by the Central Insecticides Board and Registration Committee under the Insecticides Act, 1968, with concurrent NDPS Rules, 1985 conditions and DGFT ITC (HS) policy overlays where applicable.

Is the CIB&RC registration required for every import of sodium naphthionate, or only when it is used as a pesticide?

The requirement applies where the substance figures in the Schedule to the Insecticides Act, 1968; import is then restricted to places notified under Rule 45 of the Insecticides Rules, 1971, regardless of the declared end-use.

What happens if the NDPS import certificate has expired before the consignment reaches the Indian port?

An expired import certificate under Rule 53 of the NDPS Rules, 1985 invalidates the legal basis of the import; the consignment is liable to seizure and prosecution under the Narcotic Drugs and Psychotropic Substances Act, 1985, with no retrospective extension available at the port.
