Black Iron Scale – High Fe, Low Moisture, Uniform Size Grades for Global Buyers

We export black iron scale in carefully graded forms for international buyers requiring reliable metallurgical input material. Commonly referred to as steel mill scale or iron oxide scale, it is supplied in controlled fractions such as lumps, powder, and screened intermediate sizes based on technical requirements. Export lots are selected to meet commercial expectations for high Fe content, low impurity levels, and consistent quality, ensuring predictable composition, controlled moisture, and stable physical characteristics. Grading, moisture limits, and particle distribution are managed through defined export preparation and inspection procedures. Black iron scale is a dense, high-iron material widely used in sintering, pelletizing, cement kilns, and other metallurgical applications. Buyers typically require uniform size material with controlled particle size, consistent bulk density, and narrow size tolerance to maintain process efficiency and handling reliability. We work with international buyers who require stable technical parameters and shipment consistency across orders, supporting procurement needs in multiple regions and industrial applications.
