Silicon Metal Powder Price Per Kg and Per Ton in the Chinese Market

Silicon Metal Powder Prices in China on 5 August

Silicon metal powder is produced by crushing and screening metallurgical-grade silicon, and the fine fractions are sold to the refractory, aluminium and chemical industries as well as to steelmakers that require a faster-dissolving deoxidiser. The domestic table below quotes yuan per tonne and separates the offer price from the price at which material actually changed hands.

Specification	Quote (CNY/t)	Movement	Sold price (CNY/t)	Movement
553, 16-200 mesh	10600-10900	Flat	10000-10600	Flat
Si 99 percent min, 16-200 mesh	10700-11000	Flat	10100-10600	Flat

Two details matter when reading this table. First, the gap between the quoted level and the sold level is around 300 to 600 yuan per tonne, which is the normal negotiating margin in the domestic powder market. Second, the premium for Si 99 percent minimum material over the standard 553 grade is only about 100 yuan per tonne at the offer level, so the chemistry upgrade is inexpensive relative to the base price. Both rows are marked flat, meaning that neither the offer nor the transaction level moved on the assessment date.

Mesh Size and the Cost of Grinding

The 16-200 mesh range is a broad industrial band rather than a single product. Powder is screened into cuts, and the price within the band rises as the cut becomes finer, because each additional screening step consumes energy and generates a yield loss of coarse off-spec material that must be returned to the mill.

Coarse cuts at the 16 to 60 mesh end dissolve more slowly but flow freely and are preferred for gravity-based feeding systems.

Mid cuts around 60 to 120 mesh are the general-purpose fraction for deoxidation and for aluminium alloy addition.

Fine cuts toward 200 mesh dissolve quickly and disperse evenly, but they dust readily and require sealed packaging and dust extraction at the point of use.

Finer than 200 mesh, the powder becomes a chemical and refractory feedstock and is priced on a different basis altogether.

International Industrial Silicon Prices on the Same Date

China is the dominant supplier of industrial silicon, so the assessment also records the delivered prices that Chinese material commanded in overseas markets. These figures are useful because they show how much of the domestic price is absorbed by freight, duty and local distribution.

Grade	Destination	Price range	Unit and term
553	Japan	1350-1380	USD per tonne, CIF Yokohama
441	Japan	1400-1450	USD per tonne, CIF Yokohama
553	South Korea	1350-1380	USD per tonne, CIF Busan
441	South Korea	1400-1450	USD per tonne, CIF Busan
553	India	1350-1380	USD per tonne, CIF Nhava Sheva
441	India	1400-1450	USD per tonne, CIF Nhava Sheva
553 and 441 equivalent	North America	1.45-1.60	USD per pound, DDP
553 and 441 equivalent	Europe	2200-2350	Euro per tonne, DDP

Asian destinations settle in the range of 1350 to 1450 USD per tonne, with the 441 grade consistently about 50 USD per tonne above 553 because of its tighter iron, aluminium and calcium limits. The North American figure is quoted per pound and the European figure per tonne in euro, so neither can be compared directly with the Asian numbers without a unit and currency conversion.

China Export Prices on 5 August

Export quotations are assessed separately from the domestic market because they are quoted FOB Huangpu Port and include the grades that overseas buyers specify most often.

Grade	Tax-inclusive quote (USD/t)	Movement	Delivery term
421	1500-1550	Flat	FOB Huangpu Port
2202	2150-2250	Flat	FOB Huangpu Port
3303	1530-1560	Flat	FOB Huangpu Port
441	1380-1430	Flat	FOB Huangpu Port
553	1340-1360	Flat	FOB Huangpu Port

The ordering of these grades is the opposite of what a buyer might expect from the four-digit grade code alone. The highest quotation belongs to 2202, the most refined grade, at 2150-2250 USD per tonne, while 553, the standard metallurgical grade, sits at the bottom of the table. Grade 421 sits above 3303 and 441 because it pairs a low iron level with a low calcium level, and those two limits together are more difficult to hold than a single low figure.

What Determines the Daily Silicon Powder Price

Furnace power cost in the producing provinces, which is the largest single component of the cost of metallurgical-grade silicon.

Feedstock quality, including the purity of the quartz and the ash and reactivity of the carbon reductant.

The balance between metallurgical demand from steel and aluminium and chemical demand from silicone and polysilicon producers.

Grinding and screening capacity, since powder is a fabricated product and its price also carries the milling cost and the yield loss.

Export logistics, including container availability at Huangpu Port and the exchange rate applied to the dollar quotations.

Frequently Asked Questions

Q: What is the price of silicon metal powder today?
On 5 August, 553 grade powder sized 16-200 mesh was quoted at 10600-10900 CNY per tonne and sold at 10000-10600 CNY per tonne. Material at Si 99 percent minimum in the same size range was quoted at 10700-11000 CNY per tonne and sold at 10100-10600 CNY per tonne.

Q: What is the price per kilogram?
Taking the sold price of 10000-10600 CNY per tonne for 553 powder, the equivalent is roughly 10.00 to 10.60 CNY per kilogram, before packaging and freight. The quoted offer level converts to approximately 10.60 to 10.90 CNY per kilogram.

Q: How much does industrial silicon powder cost per tonne?
Domestic 553 powder traded at 10000-10600 CNY per tonne on 5 August, while export quotations for the same grade were 1340-1360 USD per tonne FOB Huangpu Port. The domestic and export figures are quoted in different currencies and on different delivery terms.

Q: Why is the sold price lower than the quoted price?
The published quote reflects the level at which sellers offered material, while the sold price records the level at which transactions were concluded. The 300 to 600 CNY per tonne difference between the two is the normal negotiating margin in this market.

Q: Which grade should a steel mill choose for deoxidation?
Standard 553 powder is adequate for routine deoxidation, while grades such as 441, 3303 and 2202 are selected where lower iron, aluminium or calcium limits are required. The price difference between neighbouring grades is modest compared with the cost of a rejected heat.

Q: Why are all the prices marked flat?
Every grade in both the domestic and export tables showed no movement on the assessment date, which indicates a balanced market where supply and demand were matched at the prevailing level rather than a market that failed to trade.
