8106.90.00.00 - Other

This HTS category, 8106.90.00.00, encompasses articles made from bismuth that do not fall into the more specific classification for highly pure bismuth. It broadly covers a wide array of bismuth-containing items, including manufactured products, alloys where bismuth is a principal component but not exceeding the purity threshold of the sibling category, and potentially bismuth waste and scrap that doesn't meet the stringent purity requirements for direct reclassification. The scope here is for any bismuth article not explicitly defined elsewhere in Chapter 8106.

In contrast to its sibling category, 8106.10.00.00, which is reserved for bismuth containing more than 99.99 percent of bismuth by weight, this "Other" category captures articles with a lower bismuth purity or those where bismuth is combined with other base metals or non-metals to form distinct alloys or compounds. The key differentiator lies in the compositional analysis and the specific form of the article, ensuring that items not meeting the highest purity standard for elemental bismuth are appropriately classified.

As this is a leaf node, there are no further subcategories within 8106.90.00.00. Therefore, classification into this category is determined by the absence of specific criteria for more detailed classifications within the bismuth product chapter. Importers and exporters should carefully consider the composition and form of their bismuth articles, ensuring they are not inadvertently placed in a more precise or restrictive category before resorting to this residual classification.
