7110.11.00.10 - Grain and nuggets of the metal platinum

This HTS classification covers platinum in specific physical forms: grain and nuggets. These represent semi-processed states of platinum metal, typically produced by melting and then solidifying the metal in a manner that results in small, irregular particles (grain) or larger, more rounded masses (nuggets). This category is distinct from other unwrought or powder forms of platinum, focusing specifically on these identifiable granular or lump-like formations of the pure metal.

The distinction between "grain and nuggets" and its sibling category, "sponge of the metal platinum" (7110.11.00.20), lies in the physical structure and processing. Sponge platinum is a highly porous, foam-like mass, distinct from the more compact and defined shapes of grain and nuggets. The "Other" category (7110.11.00.50) serves as a residual classification for any unwrought or powder forms of platinum not specifically meeting the definitions of grain, nuggets, or sponge.

As a leaf node within the HTS structure, this category does not have further subdivisions. Classification into 7110.11.00.10 is determined by the physical appearance of the platinum material as either grain or nuggets, indicating a level of processing beyond the initial smelting but not yet shaped into finished articles or more specialized forms like sponge.
