NPK compound fertilizer price per ton in 2026: 15-15-15, 20-20-20 and 17-17-17

NPK prices per ton by grade

The bands below are indicative bulk-export levels. Higher-analysis grades (more total nutrients) cost more per ton because they require more raw material per finished ton. For the full ratio range, see the fertilizer export catalog.

Specialty grades — water-soluble NPK for fertigation, NPK with micronutrients, chloride-free K sources — sit above these bands because they add soluble carriers or micronutrient packages.

How to read the N-P-K ratio

The three numbers on an NPK grade are the percentage by weight of each primary nutrient: N (nitrogen), P2O5 (phosphorus pentoxide) and K2O (potassium oxide). So 15-15-15 means 15% N, 15% P2O5 and 15% K2O — 45% total nutrients, with the remainder being filler, conditioning agents and moisture.

The ratio tells the buyer the agronomic purpose:

• Balanced grades (15-15-15, 17-17-17, 20-20-20) — general-purpose base dressing for soils without a strong deficit in one nutrient.
• Nitrogen-forward (24-8-7, 20-10-10) — vegetative growth, cereals and top-dressing where phosphate and potash are adequate in soil.
• Phosphate-rich (12-24-12, 6-24-12) — starter and establishment, root development, deficient soils.
• Potash-rich (10-10-20, 8-20-30, 4-12-32) — quality and fruiting crops, tubers, chloride-tolerant feeders.

Because the ratio changes how much of each raw material is in the ton, the price moves with it. A potash-heavy grade rises when MOP rises, even if nitrogen is flat.

Why higher-analysis NPK costs more per ton

A common point of confusion is that 20-20-20 (60% nutrients) costs more per ton than 15-15-15 (45%). This is not a quality premium — it is a material content difference. To make one ton of 20-20-20, the producer must put more actual nitrogen, phosphate and potash into the granule than for one ton of 15-15-15.

On a per-unit-of-nutrient basis, the grades are often close. The headline price-per-ton difference therefore mostly reflects how much active nutrition you are buying, not a markup. Buyers comparing NPK grades should look at cost per unit of N, P2O5 and K2O, not just cost per ton.

What drives NPK compound prices

NPK pricing inherits the cost structure of its three input families, plus a compounding premium:

1. Nitrogen component — tracks urea and ammonia, which are gas-linked. A natural gas price shock lifts the N side of every NPK grade.
2. Phosphate component — tracks DAP/MAP, which are driven by rock phosphate, sulfur and ammonia. Tender demand from India and Brazil moves the P side.
3. Potash component — tracks MOP (and SOP for chloride-free grades). Potash is supply-disciplined, so the K side is the most stable but also the quickest to spike on supply news.
4. Compounding premium — the cost of manufacturing, granulation, conditioning and the producer's margin, added on top of the raw-material blend.

Because NPK is a blend, it rarely spikes as sharply as a single-nutrient fertilizer — but it also rarely falls as fast, since one input can offset another.

Standard compound vs custom NPK blend

Buyers have two routes:

• Standard compound NPK (15-15-15, 20-20-20, etc.) — produced in fixed ratios, available off the shelf, faster to ship, priced transparently. Best when a balanced or common ratio fits the crop programme.
• Custom NPK bulk blend — engineered to a buyer's target ratio and soil-test results. Priced off the same three inputs, plus a blending fee. Best for distributors, cooperatives and large farms with a defined agronomic specification.

Custom blends are quoted against a specific N-P-K target and volume; see custom NPK bulk blend for the specification process.

FOB and CIF pricing for NPK

The bands above are export (FOB/CFR) levels. A CIF NPK quotation adds freight and insurance to the destination port, so it depends on the discharge port, vessel size and current freight market. As with all fertilizer, a firm CIF price cannot be issued without a named destination port, volume, packaging and shipment window.

For NPK specifically, packaging also matters more than for urea or DAP: water-soluble grades are usually packed in smaller bags for fertigation, while granular compounds ship in bulk or jumbo bags. The packaging decision affects both price and discharge logistics.

How to read an NPK quotation

When comparing NPK offers, check:

• that the grade and ratio match exactly (15-15-15 is not the same as 16-16-16 on a per-nutrient basis);
• total nutrient content — compare cost per unit of nutrient, not just per ton;
• the Incoterm basis (FOB vs CIF) and whether freight is included;
• packaging — bulk, jumbo or 50 kg, and whether water-soluble grades are offered;
• whether micronutrients or chloride-free K are included (these change the band);
• origin and realistic loading window.

An NPK offer far below the indicative band, with no material-content rationale, is a red flag — the grade may be mislabeled or the allocation weak.
