7601.10.60.40 - Of 99.9 percent aluminum or greater

This HTS category, 7601.10.60.40, specifically classifies unwrought aluminum that is highly pure, defined as containing 99.9 percent aluminum or greater. Unwrought aluminum refers to the primary metal in a state ready for further processing, such as casting into ingots, billets, or slabs. This classification is crucial for importers and exporters dealing with refined aluminum intended for specialized applications where high purity is a critical requirement.

This category is distinguished from its siblings by its stringent purity threshold. It is separate from 7601.10.60.45, which covers unwrought aluminum with a purity between 99.8 percent and less than 99.9 percent, and from 7601.10.60.90, which encompasses all other unwrought aluminum that does not meet these specific high-purity criteria. The precise percentage of aluminum content is the determining factor for classification within these related categories.

As this classification is a leaf node, there are no further subcategories. Therefore, the focus remains on the precise material specification. Importers and exporters must ensure their documentation accurately reflects the certified aluminum content of the unwrought product to ensure correct classification and adherence to customs regulations. This highly pure form of unwrought aluminum is typically used in demanding industries such as electronics, aerospace, and high-performance manufacturing where even minor impurities can negatively impact the final product's properties.
