UK-Australian metal producer Rio Tinto on 13 May sold its first cargo of Pilbara Blend Fines (PBF) iron ore with a revised iron content specification of 60.8pc. Years of grade challenges have led to declining volumes of the blended product, which previously contained 61.6pc Fe.
Rio Tinto continues to review product strategy, based on consumer needs and available ore grades, the company told Argus on 13 May. It has notified consumers of Pilbara Blend specification changes and is engaging with them, a spokesperson added.
Over the past year, market participants have reported rising volumes of the company's SP10 blend — which has a lower iron ore content, but higher alumina and phosphorus levels, than PBF — being sold into China's portside market to maintain the grade of its PBF product. The reduction in grade in PBF is expected to result in greater volumes of its flagship product being available.
Rio Tinto said the average realised fob price from its Australian assets was $97.40/dmt last year — slightly below Argus' average 2024 iron ore fines 62pc Fe (ICX) fob Australia netback of $98.46/dmt. Rio Tinto's realised fob price includes fines and lump products from across Western Australia. These include lower-grade products and the more-valuable lump, which accounts for about 30pc of total sales over most quarters.
Rio Tinto is not the only company facing grade challenges. Typical grades for Australia's BHP have also been steadily declining over recent years, and ores typically deliver below 62pc Fe. Mineral Resources' average ore grade at its 10mn t/yr Pilbara Hub complex was 57.3pc in July 2024-March 2025, down from 58.2pc a year earlier.
Argus' iron ore fines 62pc Fe (ICX) cfr Qingdao price was assessed at $102.40/dmt today, down from $98.95/dmt on 14 April. Rio Tinto's revised PBF product with July delivery traded at $96.41/dmt.
Argus plans to launch an assessment for 61pc Fe iron ore fines next month to reflect the ongoing decline in average grades in Australia's Pilbara region. The new price will be calculated from the same underlying spot data as the existing ICX 62pc Fe benchmark.
