scrap metal

For purposes of this subsection, the term “scrap metal” means bits and pieces of metal parts (e.g., bars, turnings, rods, sheets, wire) or metal pieces that may be combined together with bolts or soldering (e.g., radiators, scrap automobiles, railroad box cars), which when worn or superfluous can be recycled, except for scrap metals that the Administrator excludes from this definition by regulation.
