Metal Bulletin is planning to change the frequency of assessment for its Chinese ammonium paratungstate (APT) export price quotation from Friday January 29 subject to the result of a market consultation.

The spot market is agreed to be illiquid and the change is aimed at allowing Metal Bulletin to capture a larger number of data points, from as many market participants as possible.

From January 29, the frequency of publication would be changed to every Wednesday between 14:00 and 15:00 London time.

Market participants have until January 25 to respond to this notice.

The chemical specification and delivery terms would be as follows:
