8104.30.00.00 - Raspings, turnings and granules, graded according to size; powders

This HTS category, 8104.30.00.00, specifically addresses forms of magnesium that are in a fragmented or finely divided state. It encompasses raspings, turnings, and granules of magnesium that have been sorted or graded based on their particle size. Additionally, it includes magnesium in powder form, regardless of its particle size. These forms are typically generated during the processing or machining of magnesium metal.

It is crucial to distinguish this category from its siblings. While 8104.20.00.00 covers "Waste and scrap," this category focuses on processed, size-graded, or powdered forms of magnesium, not raw or unusable remnants. Furthermore, "Unwrought magnesium" (implied as a sibling) refers to primary forms like ingots or bars, whereas 8104.30.00.00 deals with significantly reduced particle sizes. The "Other" category (8104.90.00.00) would encompass any magnesium articles not specifically covered by the preceding subheadings.

As a leaf node, this category does not have further subcategories. Therefore, classification within 8104.30.00.00 relies on the physical characteristics of the magnesium product itself – specifically, whether it is in the form of graded raspings, turnings, granules, or powder. The grading by size is a key defining characteristic for raspings, turnings, and granules within this specific subheading.
