2804.69 - Other:

This HTS category, 2804.69, encompasses silicon that does not meet the high purity threshold specified in sibling category 2804.61. It covers silicon in various forms and purities, excluding those with a silicon content of 99.99 percent or more by weight. This classification is relevant for silicon used in a wide range of industrial applications where ultra-high purity is not a critical requirement.

The distinction from the sibling category, 2804.61 (Silicon containing by weight not less than 99.99 percent of silicon), is based solely on the measured purity of the silicon. This subcategory captures materials that, while still silicon, have a slightly lower purity level, making them suitable for different manufacturing processes or end uses. The focus remains on the elemental nature of silicon and its classification within the inorganic chemicals chapter.

Within this category, further subdivisions exist to refine the classification based on specific purity ranges and further distinctions. Subcategory 2804.69.10.00 details silicon containing by weight less than 99.99 percent but not less than 99 percent of silicon, while 2804.69.50.00 covers all other silicon not meeting the preceding purity criteria. These subdivisions allow for more granular tracking and appropriate duty assessment based on the specific grade and composition of the silicon being imported or exported.
