After a consultation period
, Metal Bulletin has launched a price assessment to cover the Chinese cobalt sulfate market. Cobalt sulfate, of which China is the largest producer in the world, is one of the key materials used to produce lithium-ion nickel-cobalt-manganese (NCM) and nickel-cobalt-aluminium (NCA) batteries used in electric vehicles (EVs).
Therefore, Metal Bulletin aims to provide a regular tracker of Chinese cobalt sulfate prices on a spot basis and capture the evolution of the cobalt sulfate market
in the country.
The newly launched China cobalt sulfate price assessment will enhance Metal Bulletin’s coverage of the battery raw materials supply chain
in response to the looming EV boom.
In addition, the new price assessment will also serve as an essential complement to Metal Bulletin’s existing coverage of cobalt prices, which include low-grade
cobalt prices on a $ per lb basis, as well as Chinese cobalt metal
prices on a yuan per tonne basis.
The specification, delivery terms and publication timing of the China cobalt sulfate price assessment, which will be added to Metal Bulletin’s price book
on Wednesday May 2, are as follows:
Price: China cobalt sulfate, Co 20.5% min, ex-works, adjustment to low-grade cobalt low-end price at Co 20.5% basis, $/lb
USD per lb
: crystal; feed from cobalt ores & concentrates, cobalt intermediates, such as crude cobalt hydroxide (materials produced from cobalt scrap are excluded)
Co: 20.5% min, Ni: 0.001% max, Cu: 0.001% max, Fe: 0.001% max, Zn: 0.001% max
on bank acceptance (other payment normalized)
within 30 days
twice a week on Wednesday and Friday, between 2pm and 3pm London time
To calculate the adjustment, spot cobalt sulfate data will be collected in yuan per tonne and Metal Bulletin will use the US dollar sell price published by the Bank of China every Wednesday and Friday at about 3pm Shanghai time.
The formula to calculate the adjustment is as follows:
a. China cobalt sulfate price/1.16*/forex rate/2,204.62 = China cobalt sulfate, ex-works, $/lb
b. Metal Bulletin low-grade low-end price x 0.205 = Metal Bulletin low-grade cobalt low-end price at Co 20.5% basis, $/lb
Final premium/discount, $/lb = a-b
*China’s value-added tax (VAT) has been adjusted to 16% from 17%, as specified in the consultation notice, to reflect the decision by the country’s Finance Ministry and State Administration of Taxation to cut VAT on all imported goods by 1 percentage point, effective May 1, 2018.
Metal Bulletin has no financial interest in the level or direction of this assessment.
