7403.13.00.00 - Billets

This category, HTS Code 7403.13.00.00, specifically classifies "billets" of refined copper. Billets are semi-finished products of refined copper, typically cast in a shape that is then further processed through hot rolling, extrusion, or drawing to produce final products such as bars, rods, wire, or tubes. They are characterized by their generally rectangular or circular cross-section and are intended for subsequent manufacturing operations.

Distinguishing this category from its siblings, it's important to note that while all fall under unwrought refined copper, billets differ in form and intended use. Cathodes and sections of cathodes (7403.11.00.00) are the direct product of electrolysis and are typically remelted. Wire bars (7403.12.00.00) are specifically shaped for the production of copper wire. "Other" refined copper (7403.19.00.00) encompasses any refined copper forms not specifically defined by the preceding subheadings. Billets, therefore, represent a distinct intermediate shape destined for a broader range of downstream metal forming processes.

As this is a leaf node in the HTS, there are no further subcategories under 7403.13.00.00. Classification within this heading relies on the physical form of the refined copper. Therefore, the crucial determinant for classifying goods under this code is whether the article is indeed a billet of refined copper, distinguished by its semi-finished, cast shape and its clear role as an intermediate product for further fabrication into more finished copper articles.
