Questions phosphate buyers ask

Granular MAP including 11-52-0 and the Chinese grades 10-50-0 and 11-44-0; DAP 18-46-0; TSP 0-46-0; SSP in the grade your market uses; and water-soluble MAP 12-61-0, MKP 0-52-34 and urea phosphate 17-44-0. Phosphoric acid, phosphate rock and the feed phosphates are described on the site for reference but are not currently offered.

Nitrogen, available phosphate and potassium, in that order, as percentages by weight. DAP 18-46-0 is 18% N and 46% P2O5 with no potassium. TSP 0-46-0 has no nitrogen. The zero matters: it tells you the product contributes nothing to that nutrient, which is exactly what you want when the other two are already balanced.

Available P2O5 is what the standard citrate extraction shows the plant can access; it includes the water-soluble fraction plus the fraction that becomes available in the soil. Water-soluble P2O5 dissolves immediately. MAP and DAP typically run 87–90% of their available P2O5 as water-soluble. The exact figure belongs on the lot COA, and the basis belongs in the contract.

Because blending plants buy on nutrient cost, not on grade name. A 10-50-0 or 11-44-0 granule is cheaper per tonne and is used to bring phosphate into a compound that is already receiving P2O5 from another source. If you need the highest concentration for a long freight leg, specify 11-52-0.

No. Both are monoammonium phosphate, but 11-52-0 is a granule with filler and a partly soluble phosphate, made for soil application. 12-61-0 is a purified crystal with essentially no insoluble residue, made to dissolve. Substituting one for the other in a fertigation programme will block the system.

We supply the phosphate component and can discuss compound formulations built on it. A finished NPK is a separate product with its own formulation, granulation and registration requirements, and it is quoted per formulation rather than from a list.

Quotations are mainly FOB Chinese ports. CFR or CIF may be considered on request, subject to confirmation at the time of quotation — ocean freight moves, so a CFR or CIF rate is confirmed against the sailing rather than published as a standing figure. Send the discharge port and the basis you want to work on, and the quotation states which basis it is issued on so it can be compared directly with the offers already on your desk.

Payment is by T/T, subject to agreement for the specific order. The deposit and balance terms are stated in the sales contract. The deposit and balance split, and the timing of each, are agreed for the order and written into the sales contract. They are not published here because they depend on the product, the quantity and the relationship, not on a standard schedule.

It depends on the product and the destination. Bulk MAP and DAP usually move by the container or the vessel lot. Water-soluble grades such as MKP move in smaller quantities, commonly a few hundred tonnes. A trial lot is possible on some grades. Ask with your requirement and you will get a straight answer rather than a floor price.

The loading port is named in the quotation. It follows the production source and the sailing available at the time of booking, and it is confirmed in the sales contract before shipment.

Lead time depends on whether the grade is on the current production schedule, on the packaging, and on the sailing. It is quoted per order. What we will not do is give a delivery date before the grade and quantity are fixed, because that date would be a guess dressed up as a commitment.

No. Fertilizer registration and import licensing are the importer's responsibility and are issued in the destination country. What we can do is supply the product documentation the registration requires — COA, TDS, MSDS, composition and origin — in the form your authority asks for.
