A word of counsel

The most common error on this tariff line is importing under a commercial grade specification that does not exactly match the grade or mixture ratio recognised under the Fertiliser (Control) Order, 1985. Mixtures of monoammonium phosphate and diammonium phosphate are specifically captured as a distinct product within the FCO framework; importers who treat a blended product as a straight MAP or DAP shipment risk detention and grade-mismatch enforcement at the port.

Frequently asked

Does HSN 3105 40 00 require BIS certification?

No, monoammonium and diammonium phosphate fertilisers are not within the BIS Quality Control Order regime. Import compliance is governed by the Fertiliser (Control) Order, 1985, which prescribes grade specifications, labelling, and distribution conditions for fertilisers imported into India.

Does the Fertiliser (Control) Order, 1985 cover mixtures of monoammonium phosphate and diammonium phosphate?

Yes. HSN 3105 40 00 expressly covers both monoammonium phosphate and its mixtures with diammonium phosphate, and the FCO applies to this combined product family as amended from time to time.

What happens if the imported fertiliser does not conform to the FCO grade specification?

Non-conforming consignments are liable to detention at the port of import, and customs out-of-charge will be withheld until conformance is established or the consignment is re-exported.
