Ferrophosphorus Prices: Regional P24 Quotes and Cost Drivers

What Ferrophosphorus Is and How It Is Priced

Ferrophosphorus is an iron-phosphorus master alloy used to add phosphorus to steel and cast iron and to assist deoxidation in the ladle. It is produced in submerged-arc electric furnaces from a phosphate-bearing charge, an iron source and a carbon reductant, then cast, cooled, crushed and screened into graded lump. Because the raw materials, the electricity and the screening all contribute to cost, the ferrophosphorus price moves with a different set of drivers than the price of a simple scrap-based alloy.

Commercial material is described by its nominal phosphorus content, and P24 is the grade quoted most often in the domestic market, carrying roughly 23–27% phosphorus with the balance iron and limited silicon, carbon, sulphur and manganese. Price is normally stated per tonne, ex-works, and the quotation only becomes comparable once size range, packing, tax treatment and delivery basis are known.

Ferrophosphorus Price Levels by Region

The table below records the quotations collected in early June 2025 for P24 material from the main producing regions. Prices are shown as published, with the delivery basis and packing stated in each line, because an ex-works ton bag price and an export price in US dollars are not directly comparable.

Region	Grade	Price	Unit	Basis and packing
Sichuan	P24	3,850–4,000	CNY/tonne	National standard, ton bag, ex-works, tax included
Henan	P24	3,500–3,700	CNY/tonne	National standard, 10–50 mm, ton bag
Yunnan	P24	3,500–3,600	CNY/tonne	National standard, 10–80 mm, ton bag
Guizhou	P24	515.5	USD/tonne	Export-oriented quotation

Read together, the quotes show a domestic band of roughly 3,500–4,000 CNY per tonne for P24, with a spread of about 400 CNY between the lowest and the highest region on the same day. A spread of that size is normal in the ferrophosphorus market and is explained by power cost, distance to the end user and the packing and size specification behind each line, not by a difference in the phosphorus content of the grade.

What Drives the Ferrophosphorus Price

Phosphate feedstock: the cost of phosphate rock and phosphorus-bearing by-product sets the floor for the alloy, and any tightening in that market reaches ferrophosphorus within weeks.

Electricity: ferrophosphorus is made in an electric furnace, so power tariffs and any curtailment in the producing provinces directly change the conversion cost.

Reductant and iron unit: coke or anthracite and the iron-bearing charge move with their own markets and are usually a smaller but still visible part of the cost.

Size and screening yield: a tight size band such as 10–50 mm generates more fines and reduces yield, so a narrow specification usually carries a premium over a wide 10–80 mm range.

Packing and freight: ton bags, palletising and long-haul transport all add to the landed cost even when the ex-works price is unchanged.

Demand from steel and foundry: consumption in steelmaking and in cast-iron foundries sets how quickly producers can pass cost increases through.

Because these drivers are independent, a rise in the published offer does not always mean a rise in the buyer's cost. A change in packing, a switch from a narrow to a wide size band, or a different delivery basis can offset a headline increase.

Grade, Specification and Unit Traps

Two offers for "P24 ferrophosphorus" can differ by several hundred per tonne with neither seller being wrong. The unit is the first trap: a price in US dollars per tonne is an export or reference quotation, while a domestic price in CNY per tonne usually includes tax. The second trap is the size range, because 10–50 mm and 10–80 mm are different screening jobs with different yields. The third is packing: ton bag, drum or bulk changes handling cost and sometimes the moisture pick-up on arrival.

A practical comparison therefore lists, for each offer, the grade and analysed phosphorus content, the size range in millimetres, the packing, whether tax is included, and the delivery basis. Only the offers that share the same five items can be ranked on price alone.

How Buyers Compare Offers in Practice

Convert every offer to a single basis, preferably CNY per tonne delivered to the works, tax included

Check the analysed phosphorus content of the actual lot, not only the nominal grade name

Confirm the size range against the handling system and the melting practice on site

Ask for the moisture and fines content so that a cheap price per tonne is not eroded on arrival

Weigh the stability of supply over the year, because a short-term saving is quickly lost when a delivery slips

For continuous consumers, such as a foundry adding ferrophosphorus to every heat, the right test is cost per unit of phosphorus actually recovered in the bath, not the headline price per tonne.

Outlook for Ferrophosphorus Prices

Ferrophosphorus remains a comparatively small alloy, produced in a limited number of regions, which makes its price more sensitive to local power and feedstock conditions than to global metal sentiment. When the phosphate feedstock market is firm and power costs are stable, prices tend to hold in a narrow band; when either moves sharply, the spread between regions widens before it narrows again. Buyers who hold a qualified second source and who keep their specification flexible on size range are best placed to absorb those swings.

Frequently Asked Questions

Q: What is a normal ferrophosphorus price?
In early June 2025 P24 material was quoted at roughly 3,500–4,000 CNY per tonne ex-works in the main domestic producing regions, with an export-oriented quotation from Guizhou at 515.5 USD per tonne.

Q: Why is the Guizhou price quoted in US dollars?
That line is an export or reference quotation rather than a domestic ex-works price, so it is stated in USD per tonne and cannot be compared directly with the CNY ex-works figures.

Q: Does the size range change the price?
Yes. A narrow band such as 10–50 mm produces more fines and lowers screening yield, while a wide 10–80 mm band is more economical to produce.

Q: Is tax included in published ferrophosphorus prices?
Not always. Some domestic quotations are ex-works with tax included, while others are stated before tax or on a delivered basis, so the basis must be confirmed line by line.

Q: What does P24 mean?
P24 is the grade designation for ferrophosphorus with a nominal phosphorus content of about 24%, typically supplied in the 23–27% range with the balance iron.

Q: Which factors move the ferrophosphorus price fastest?
Electricity tariffs and phosphate feedstock costs, because ferrophosphorus is produced in an electric furnace from a phosphate-bearing charge.
