7409.90.50 - Of a width of 500 mm or more

This HTS category encompasses copper plates, sheets, and strip, specifically those formed from "other copper alloys" (not primary copper or specific alloys listed elsewhere) with a thickness less than 5 mm. The defining characteristic for classification within this subcategory is that these articles have a width of 500 mm or more. This classification is applicable to products primarily intended for industrial or manufacturing use where larger dimensions are advantageous.

It is crucial to distinguish this category from its sibling, HTS 7409.90.90, which covers copper plates, sheets, and strip of other copper alloys and a thickness of less than 5 mm, but with a width of *less than* 500 mm. The primary differentiator here is the dimensional threshold of 500 mm for width, indicating a need for larger, potentially continuous or more extensive material applications.

Within this specific classification, further distinctions are made based on the precise composition of the "other copper alloys." The subcategories 7409.90.50.30 and 7409.90.50.60 allow for the separate identification of specific types of alloys. For instance, "Of beryllium copper" highlights a distinct alloy with unique properties, while "Other" serves as a catch-all for remaining copper alloy compositions that meet the width criteria but do not fall into the more specifically enumerated categories.
