8111.00.49.90 - Other

This HTS subcategory, 8111.00.49.90, encompasses unwrought manganese that does not meet the specific criteria for other classifications within the "Unwrought manganese" grouping. It serves as a residual category for manganese in its primary, unworked form, which includes various shapes and sizes of ingots, pigs, lumps, and similar crude forms that are not further processed or alloyed beyond initial smelting and casting. The key characteristic is that it represents manganese in a raw, cast, or sintered state, intended for subsequent industrial use.

This classification distinguishes itself from its sibling, 8111.00.49.10, which specifically covers manganese powder with a high purity of at least 99.5 percent by weight. Therefore, 8111.00.49.90 is for unwrought manganese that is not in powder form, or if it is in powder form, it does not meet the specified minimum purity threshold. The focus here is on the physical state and composition that differentiates it from the more precisely defined powder category.

As a leaf node, this category has no further subcategories. Therefore, classification into 8111.00.49.90 depends on the exclusion from more specific unwrought manganese categories. The decision to classify goods under this residual "Other" designation relies on a thorough assessment of the material's form, purity, and intended industrial application, ensuring it aligns with the broader scope of unwrought manganese as defined within Section XV of the Harmonized Tariff Schedule.
