The force majeure relates to exports of P1020 standard 99.7% aluminium ingot.

With critical plant equipment out of action, Sohar is finding it difficult to control quality deviations, claims Rio Tinto Alcan.

The smelter produces 100% on-spec material and currently has a capacity of 365kt/yr.

According to Rio Tinto's Bryan Tucker, the situation is under constant evaluation.

Rio Tinto has a 20% share in the Sohar facility and is responsible for managing metal exports. Liquid metal is not covered by the force majeure.
