Iron Pickling Sludge

Pickling sludge arises from acid cleaning of iron/steel surfaces to remove scale, classified as waste from iron or steel manufacture in HTS 2619.00.90.00. It contains iron oxides, acids, and metals, unsuitable for direct reuse without processing. This fits as 'other' slag, dross, or waste.
