2811.29.10.00 - Arsenic trioxide

This HTS classification, 2811.29.10.00, specifically covers arsenic trioxide. Arsenic trioxide is an inorganic oxygen compound of the nonmetal arsenic, characterized by its crystalline structure and often appearing as a white powder. Its primary use is as a precursor in the manufacturing of other arsenic compounds, and historically, it has found applications in pest control and certain medicinal preparations, though these are now highly regulated.

Within the broader category of "Other inorganic oxygen compounds of nonmetals," this code is distinct from its siblings by its specific chemical identity. For instance, 2811.29.20.00 covers selenium dioxide, while 2811.29.30.00 pertains to sulfur dioxide, both being different nonmetal oxygen compounds. The "Other" category (2811.29.50.00) serves as a residual classification for inorganic oxygen compounds of nonmetals not elsewhere specified in this subheading.

As a leaf node, 2811.29.10.00 does not have further subdivisions. Therefore, the focus for classification under this code remains on accurately identifying the substance as arsenic trioxide and ensuring it meets the general criteria for inorganic oxygen compounds of nonmetals. Proper documentation confirming the chemical composition will be essential for customs clearance.
