Nitrogenous fertilisers, other mixtures (urea, AUS 32 diesel exhaust fluid)

BIS QCO APPLICABLE · ISI MARK SCHEME · IS 5406

HSN 3102 90 90 (nitrogenous fertilisers, other mixtures) is covered by Bureau of Indian Standards Quality Control Orders. Fertiliser-grade urea must conform to IS 5406 under the ISI Mark Scheme with effect from 22 March 2023, while diesel engine NOx reduction agent AUS 32 must conform to IS 17042 (Part 1):2018 under a separate Quality Control Order effective 26 February 2024. Directorate General of Foreign Trade policy controls on urea imports apply as a separate customs-clearance overlay.

Compliance steps

1
Identify which product falls under this HSN: fertiliser-grade urea is governed by IS 5406 under S.O. 1389(E); diesel exhaust fluid AUS 32 is governed by IS 17042 (Part 1):2018 under the Diesel Engines-NOx Reduction Agent AUS 32 (QC) Order 2024 (S.O. 922(E)). Confirm the applicable IS before sourcing, as the two obligations arise from distinct QCOs.
S.O. 1389(E) dated 22-03-2023; S.O. 922(E) dated 26-02-2024
2
Source fertiliser-grade urea only from a Bureau of Indian Standards CM/L-licensed manufacturer holding a current licence against IS 5406. Verify the CM/L number, licensed product scope, and manufacturing facility on the BIS online register before placing the purchase order.

3
For agricultural-use urea imports, confirm the consignment moves only through Rashtriya Chemicals and Fertilizers (RCF), National Fertilizers Limited (NFL), or Indian Potash Limited (IPL, valid to 31-03-2026), or a Department of Fertilizers-authorised entity. Technical-grade urea for non-agricultural or industrial use or NPK manufacturing is free of this channel restriction.

4
For AUS 32 (diesel exhaust fluid), source only from a CM/L-licensed manufacturer against IS 17042 (Part 1):2018. Ensure each consignment lot bears the ISI mark and CM/L number per Scheme-I of Schedule-II to the BIS (Conformity Assessment) Regulations, 2018. Verify the licence scope covers the AUS 32 specification.

5
Quote the applicable BIS CM/L number on the bill of entry along with documentation under the Fertilizer (Control) Order, 1985. Customs verifies the CM/L in real time; an absent, expired, or scope-mismatched licence triggers consignment detention. Ensure all import channel conditions for agricultural urea are documented at filing.

A word of counsel

The most damaging error on this tariff line is treating HSN 3102 90 90 as a single-product residual and applying only one IS obligation to a mixed consignment. This HSN covers at least two legally distinct goods — fertiliser-grade urea (IS 5406, S.O. 1389(E)) and diesel exhaust fluid AUS 32 (IS 17042 Part 1, S.O. 922(E)) — each governed by a separate Quality Control Order with its own CM/L scope. Importers who source AUS 32 under a urea CM/L, or vice versa, face detention at port because the BIS register verifies product-category match, not just licence validity.

Frequently asked

Does HSN 3102 90 90 require BIS certification?

Yes. Fertiliser-grade urea must conform to IS 5406 under the ISI Mark Scheme from 22 March 2023, and diesel exhaust fluid AUS 32 must conform to IS 17042 (Part 1):2018 under a separate QCO from 26 February 2024; both require a current BIS CM/L licence.

Are there restrictions on who can import agricultural urea under this HSN?

Yes. Import of urea for agricultural purposes is channelised through RCF, NFL, or IPL (up to 31 March 2026), or Department of Fertilizers-authorised entities. Technical-grade urea for industrial use or NPK manufacturing is free of these channel restrictions.

Does a single CM/L licence cover both fertiliser-grade urea and AUS 32 under this HSN?

No. IS 5406 and IS 17042 (Part 1):2018 are separate Indian Standards issued under distinct QCOs; a CM/L licence is product-scope-specific and does not extend across both product categories.

Does the Fertilizer (Control) Order, 1985 apply in addition to the BIS QCO?

Yes. The Fertilizer (Control) Order, 1985 as amended applies independently of the BIS QCO obligation; importers must satisfy both the statutory IS conformity requirement and the Fertilizer (Control) Order documentation at the time of import.
