8104 - Magnesium and articles thereof, including waste and scrap:

This HTS category, 8104, encompasses magnesium in its various forms, along with articles manufactured from magnesium. It includes raw or primary magnesium, as well as recycled materials such as waste and scrap. Articles made from magnesium, ranging from finished products to semi-finished components, are also classified here.

Distinguishing 8104 from its siblings at the HTS database root level, it is crucial to note that this chapter is specifically dedicated to "Other base metals; cermets; articles thereof." Unlike categories covering precious metals, common metals like iron and steel, or aluminum, HTS 8104 focuses solely on magnesium and its derivatives. This ensures that trade statistics and tariff treatments for magnesium are accurately segregated.

Within the 8104 category, further subdivisions exist to refine the classification. "Unwrought magnesium" covers the primary metal forms before significant processing. "Waste and scrap" specifically addresses materials that have reached the end of their initial use but are suitable for recycling. "Raspings, turnings and granules, graded according to size; powders" captures magnesium in smaller, processed particulate forms. Finally, "Other" serves as a residual category for any magnesium-based articles or materials not specifically enumerated in the preceding subheadings, ensuring comprehensive coverage.
