Correction to rationale of copper concentrates TC index, cif Asia Pacific: pricing notice

Fastmarkets has corrected the rationale for its MB-CU-0287 copper concentrates TC index, cif Asia Pacific, which was published incorrectly on Friday September 26 due to an error in the approval process.

The rationale for MB-CU-0287 copper concentrates TC index, cif Asia Pacific, had erroneously stated that a bid had been reported in negative territory at around the mid-$100s per tonne. This has been corrected to reflect the fact that a bid was reported in negative territory around the low-$100s per tonne.

The published price is unaffected by this change.

These prices are a part of the Fastmarkets Base Metals package.
