Amendment to Bauxite fob Brazil specifications, publishing time

Fastmarkets has amended the specifications and publishing time of its price assessment for Bauxite fob Brazil following an extended consultation

The original consultation started on April 22, but was then extended on May 23. The extended consultation period ended June 23 and the changes will come into effect starting from the next assessment on July 21.

The new fob Brazil methodology specifications are as follows:
MB-BX-0015 Bauxite, fob Trombetas, Brazil, $ per dmt
Quality: Total alumina 50%; total silica 5%; Fe 20% max; moisture content 7% min, 10% max; organic carbon 0.15% max
Quantity: Min 40,000 tonnes
Location: fob Trombetas (other ports normalized)
Timing: Within two months
Unit: USD per dmt
Payment terms: 30 days after loading (other payment terms normalized)
Publication: Monthly; third Thursday of the month, 3-4pm London time
Notes: Bulk carrier

The price will be in a range rather than a single number to better reflect the market level, with a monthly publication time of 3-4pm London time to align with Fastmarkets’ other aluminium prices and the specifications have been amended to align with the recently launched Bauxite, cif China assessment.
