Proposal to amend frequency of Chinese manganese flake: pricing notice

Fastmarkets proposes to amend the frequency of the publication of its price assessment for MB-MN-0007 manganese 99.7% electrolytic manganese flake, fob China, to monthly from weekly.

Fastmarkets selects the frequency of publication of a market assessment after considering the number of data points (deals, bids, offers, deals heard and assessments) that it can reasonably expect to collect on a consistent basis over the selected period to support the price assessment process.

This proposal follows preliminary discussions with the market as well as internal meetings to review relevant Fastmarkets’ data, which suggest lower spot liquidity and data usage recently.

The proposed new specifications are listed below, with the proposed amendment of price frequency in italics:

MB-MN-0007 Manganese 99.7% electrolytic manganese flake, fob China, $/tonne 
Quality: Flake; Mn: 99.7% basis; S: 500 ppm max; P: 50 ppm max; C: 400 ppm max; Fe+Se+Si: 0.205% max; packaged as big bags or steel drums 
Quantity: Min 20 tonnes 
Location: fob China main ports 
Timing: Spot, within one week 
Unit: USD per tonne 
Payment terms: TT or LC 
Publication: Monthly, last Friday of the month 2-3pm London time

This price is part of the Fastmarkets’ Minor Metals package.

The consultation period for this proposed amendment starts on Tuesday April 1 and will end on Wednesday May 7. The amendment will then take place, subject to market feedback, with the first assessment on a monthly frequency on Friday May 30.
