As of March 5, iron ore inventories across 35 ports tracked by SMM totaled 120.86 million mt, an increase of 1.22 million mt from the previous week and 10.7 million mt year-on-year. Daily average deliveries from the 35 ports decreased 190,000 mt on a weekly basis to 2.47 million mt last week as Tangshan banned port transport from March 3 to March 6 amid stricter environmental protection restrictions.
