Classification of base metals determines tariff treatment by predominant metal by weight and defines parts of general use.

This Section sets out classification rules for goods of base metals and related articles, listing exclusions from coverage, enumerating the metals regarded as base metals, defining cermets, "waste and scrap" and "powders," and treating specified processes (breaking up ships; drawing wire) as manufacture. It prescribes alloy classification by predominating metal by weight and treats composite articles as of the predominant base metal, with particular treatment of iron/steel, classified alloys and cermets, and it defines "parts of general use."
