Mill Scale from Hot-Rolled Steel Production from Germany

Mill scale is the flaky surface of hot-rolled steel consisting primarily of iron oxides (Fe2O3 and Fe3O4), formed during the manufacturing process of steel sheets and plates. It falls under HTS 2619.00.30.00 as ferrous scale, a waste product from iron or steel manufacture containing over 50% iron by weight. This material is often collected and recycled for use in sintering processes or as a raw material in steelmaking.

Import Tips

• Verify iron content exceeds 50% through assay testing as per statistical notes; provide lab certificates to Customs for classification confirmation

• Ensure documentation distinguishes from granulated slag (HTS 2618) or non-ferrous scalings to avoid misclassification

• Check for hazardous contaminants like oils or heavy metals; may require EPA declarations if exceeding thresholds
