2804.69.10.00 - Containing by weight less than 99.99 percent but not less than 99 percent of silicon 🖩

This HTS category, 2804.69.10.00, specifically covers silicon that has a purity level of at least 99 percent but less than 99.99 percent by weight. This concentration indicates a highly refined form of silicon, often referred to as semiconductor-grade or high-purity silicon, which is crucial for various advanced technological applications. Examples of products falling under this classification would include polysilicon in granular or ingot form intended for the manufacture of integrated circuits, solar cells, and other electronic components where precise silicon purity is paramount.

At this level of the tariff schedule, it is important to distinguish this classification from its sibling, 2804.69.50.00, which is designated for "Other" silicon. While both pertain to silicon, the distinction lies in the defined purity threshold. The "Other" category would encompass silicon with purity levels outside the specific range defined here, potentially including lower-purity grades used in industrial applications like aluminum alloys or silicones, or perhaps even higher purity silicon not otherwise specified.

As a leaf node, 2804.69.10.00 does not have further subcategories. Therefore, classification within this code is definitive based on the stated purity criteria. Importers and exporters must ensure accurate documentation of the silicon's purity analysis to correctly apply this specific tariff code. The preceding parent categories, "Silicon" and "Other" within the broader "Hydrogen, rare gases and other nonmetals" chapter, confirm that the focus remains on elemental silicon and its purity.
