Clarification of germanium dioxide price assessments

Fastmarkets is clarifying recent changes to its germanium dioxide price assessments and the reintroduction of the assessment of the price for MB-GER-0001 germanium dioxide, in-whs China, $ per kg, following market feedback.

To bring our assessment of the germanium dioxide, in-whs China, price into line with the market it assesses, and after a formal consultation period, we moved to assess germanium dioxide, in-whs China, in yuan per kg (MB-GER-0006) from May 10, rather than the previous $ per kg.

Simultaneously, we introduced a price assessment for MB-GER-0005 germanium dioxide, in-whs Rotterdam, $ per kg, to serve the non-Chinese market, which became decoupled from the domestic Chinese market owing to export controls introduced by China on August 1, 2023.

Additionally, to bring continuity to our subscribers and on feedback from the market, the MB-GER-0001 germanium dioxide, in-whs China, $ per kg, price will be reintroduced from May 24 until the end of 2024, when it will be permanently discontinued.

May averages for this price will include only published prices.

The below price had been temporarily discontinued on May 10 following a procedural error.

We will continue to publish the MB-GER-0001 germanium dioxide, in-whs China, $ per kg, price assessment to give time to market participants who use this price in their contracts, to negotiate whether they want to use the germanium dioxide, in-whs China, yuan per kg, price or the germanium dioxide, in-whs Rotterdam, $ per kg, price.

The specification for the $ per kg price will be as follows (changes in italics):

MB-GER-0001 Germanium dioxide, in-whs China, $ per kg
Quality: GeO2 99.99% min, Ge 69% approx. White powder
Quantity: Min 100kg (+/- 2%)
Location: In-whs China
Timing: Prompt release
Unit: USD per kg
Payment terms: Cash, other payment terms normalized
Publication: Twice-weekly. Wednesday and Friday between 2pm and 3pm London time.
Notes: Original producer cases, normally 25kg each. This price will be discontinued at the end of 2024.

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

Fastmarkets will therefore publish three germanium dioxide prices (in-warehouse Rotterdam, $ per kg; in-warehouse China, yuan per kg; and in-warehouse China, $ per kg) for the remainder of this calendar year, at wich time the latter will be discontinued. Fastmarkets has not changed and will not change the currency for any of these prices, as had previously been announced.
