PRICING NOTICE: Proposal to change the frequency of Chinese domestic ferro-silicon assessments

Metal Bulletin is proposing to change the frequency of assessment for its Chinese free market in-warehouse ferro-silicon price from fortnightly to weekly from Friday December 2, subject to the results of a market consultation.

The proposal is due to an increase in spot activity seen in the market in recent months, leading to more data points being submitted on a fortnightly basis.

The change will allow Metal Bulletin to capture market moves faster and more frequently. The change is being made to maximise the number of market participants and data points contributing to each assessment.

Subject to the consultation, Chinese domestic free market in-warehouse ferro-silicon price will be published in the price book on every Friday with effect from December 2.

The consultation for this proposal will end on Wednesday November 30.

The full specification for the price assessment will be as follows:

Description: Ferro-silicon, min 75%, China domestic*
Price: Yuan per tonne, in-warehouse China, price for all Si grades normalised to 75% on pro rata basis
Si: 75-80%
Mn: 0.4% max
Al: 2.0% max
Cr: 0.3% max
P: 0.035% max
S: 0.02% max
C: 0.1% max

Payment terms: cash, other payment terms normalised
