Compliance steps

1
Obtain a valid PESO explosives import licence covering DNPT before filing the bill of entry. Confirm the licence is current and upload it in e-Sanchit; a PGA-facilitated bill not routed through PESO for NOC must have the licence document verified by the proper officer before out-of-charge.
Explosives Rules, 2008 · ITC (HS) Restricted import policy, Chapter 36
2
Route the consignment exclusively through a port specified under Rule 44 of the Explosives Rules, 2008. Diversion to an unspecified port exposes the consignment to seizure under the Explosives Act, 1884, regardless of licence validity.
Rule 44 of the Explosives Rules, 2008

A word of counsel

The most common error on this tariff line is securing the PESO licence without verifying the permitted port of import against the bill of lading before vessel departure. Rules 7, 14, 15 and 45 of the Explosives Rules, 2008 impose concurrent transport, storage, and handling obligations that are assessed independently of the import licence; a breach of any one of these provisions constitutes a separate Explosives Rules contravention even where the licence itself is valid.

Frequently asked

Does HSN 3606 90 93 require BIS certification?

No, DNPT falls outside the BIS Quality Control Order regime; no BIS QCO covers this product. Import is governed by Petroleum and Explosives Safety Organisation licensing under the Explosives Rules, 2008, with the ITC (HS) Restricted-import policy overlay administered by DGFT.

Which ports are permitted for import of DNPT under this tariff line?

Import is permitted only through ports specified under Rule 44 of the Explosives Rules, 2008; the current list is published by PESO and must be confirmed against the bill of lading before shipment is arranged.

What happens if the PESO licence expires between purchase order and bill of entry?

A bill of entry filed against an expired PESO licence is treated as a Restricted-import policy violation under the ITC (HS), exposing the consignment to detention, re-export, or confiscation under the Explosives Act, 1884, and DGFT enforcement.
