Launch of germanium dioxide, in-whs China, yuan/kg price assessment

Fastmarkets launched a new price assessment for MB-GER-0006 germanium dioxide, in-whs China, on Friday May 10.

The price replaces the assessment for germanium dioxide, in-whs China, whose currency unit and publication frequency were amended following a consultation period that ended on May 1.

The currency unit has been amended to yuan per kg from $ per kg, to bring the published price into line with datapoints received from contacts active in germanium dioxide on an in-whs China basis.

The new price will now be published on days that include UK public holidays. If the publication date falls on a Chinese public holiday, it will not be published.

The amendment was prompted by germanium dioxide being put under Chinese export controls from August 1, 2023, which resulted in decreased market liquidity and a decoupling of prices between China and the rest of the world.

In tandem with this launch, Fastmarkets also launched a price assessment for germanium dioxide, in-whs Rotterdam, in $ per kg, to serve market participants active outside of China.

The new specification is as follows:

MB-GER-0006 Germanium dioxide, in-whs China, yuan per kg
Quality: GeO2 99.99 % min, Ge 69 % approx. White powder
Quantity: Min 100 kg (+/- 2%)

Payment terms: Cash, other payment terms normalized
Unit: yuan per kg

The price is a part of Fastmarkets’ minor metals price package.
