Ammonium nitrate, whether or not in aqueous solution
Ammonium nitrate for explosives and nitrous oxide production
HSN 3102 30 00 (ammonium nitrate, whether or not in aqueous solution) is covered by a Bureau of Indian Standards Quality Control Order. Conformity to IS 4668 (for explosives use) and IS 13425 (for nitrous oxide production) is mandatory under the ISI Mark Scheme with effect from 24 March 1992, by virtue of S.O. 227(E). Import is additionally governed by the Ammonium Nitrate Rules, 2012, which restrict entry to specified ports and mandate strict packing, marking, and licence conditions.
- 1Source only from a Bureau of Indian Standards CM/L-licensed manufacturer holding a current licence against IS 4668 (ammonium nitrate for explosives) or IS 13425 (ammonium nitrate for nitrous oxide production), as appropriate to the end-use. Verify the CM/L number, licensed product scope, and facility on the BIS online register before placing the purchase order.S.O. 227(E) dated 24-03-1992 read with BIS (Conformity Assessment) Regulations, 2018 · IS 4668 · IS 13425
- 2Secure a valid import licence under the Ammonium Nitrate Rules, 2012 before shipment. Import is permitted only through ports specified under Rule 18 of the AN Rules, 2012; import by air is prohibited. Ensure packing strictly conforms to Rule 8 and package markings comply with Rule 9.Rule 18, Rule 8, and Rule 9 of the Ammonium Nitrate Rules, 2012
- 3Ensure every package bears the ISI mark and the supplier's CM/L number under Scheme-I of Schedule-II to the BIS (Conformity Assessment) Regulations, 2018. Marking must appear on the product packaging itself in the form and manner prescribed under the AN Rules, 2012.Scheme-I of Schedule-II to the BIS (Conformity Assessment) Regulations, 2018 · Rule 9 of the Ammonium Nitrate Rules, 2012
- 4If the consignment equals or exceeds 350 tonnes of ammonium nitrate (industrial) or 1,250 tonnes in fertiliser form, obtain the requisite insurance for fulfilling the Employer's Relief Fund obligation under the Public Liability Insurance Act, 1991 before import.S.O. 227(E) dated 24-03-1992 read with the Public Liability Insurance Rules, 1991 · Sl. No. 126 of S.O. 227(E)
- 5Quote the supplier's BIS CM/L number and the AN Rules licence reference on the bill of entry. Customs verifies the CM/L in real time against the BIS register and checks port eligibility under Rule 18; an absent, expired, or scope-mismatched CM/L, or arrival at a non-specified port, triggers consignment detention.BIS Act, 2016 · Ammonium Nitrate Rules, 2012 · Customs Act, 1962
The single most common error on this tariff line is importing against a CM/L licence anchored to the wrong end-use standard — IS 4668 covers ammonium nitrate for explosives, while IS 13425 governs production of nitrous oxide; a licence under one does not satisfy the QCO obligation for the other. Customs and the explosives-licence authority verify end-use declaration against the CM/L scope at port; a mismatch between the declared use and the licensed standard results in detention and potential confiscation under the Ammonium Nitrate Rules, 2012, compounding the BIS non-compliance liability.
