From an IMERYS mine in India. Hammill and Gillespie are importing it and are confident that the level of quality is good and it has almost the same chemistry as the G200 EU. They have product for testing in New Jersey (early 2024). The lead-time to a West Coast port is 10 to 12 weeks. It seems to have an impossibly low Fe2O3 content.

Available in 20, 40, 50 kg bags and 800,1000,1200,1250,1350 kg bulk bags.
