Steel Pickling Scale Residue from Mexico
Iron oxide residue recovered from acid pickling baths used to clean steel surfaces during manufacturing, primarily hematite and magnetite particles. It qualifies as ferrous scale under HTS 2619.00.30.00 due to its origin as waste from steel processing with significant iron oxide content. Often reused in cement production or iron recovery.

Import Tips
• Provide pickling process documentation and iron assay (>50%) to confirm classification over chemical residues
• Test for acid residuals; neutralize if pH <6 to meet non-hazardous import standards
• Label containers with UN proper shipping name if classified as hazardous due to corrosivity
