Proposal to amend publication time of inferred China cobalt hydroxide price assessment

Fastmarkets proposes to amend the publication time of its inferred China cobalt hydroxide price assessment from 3:00 pm London time to 3:30 pm.

The proposed change to the timing of the publication of the cobalt hydroxide, min 30% Co, inferred, China, will give the calculation more time to align with the cobalt standard grade, in-whs Rotterdam, which is published daily at 3:00pm London time.

The daily cobalt hydroxide inferred price is calculated by multiplying the low-end of the cobalt standard grade, in-whs Rotterdam price assessment by the prevailing midpoint of Fastmarkets’ cobalt hydroxide payable (percentage) indicator, min 30% Co, cif China.

The consultation period for this proposed amendment starts from Friday April 1 and will end on May 2. The amendment will then take place, subject to market feedback, on May 5.
