Subheadings
Products classified under Tariff item 2804.80.00
Arsenic Ingot (Research Grade)
Solid arsenic ingots of 99.99% purity, used for laboratory research in materials science and toxicity studies. This is elemental arsenic, a non-metal, meeting Chapter 28 definitions for separate chemical elements, whether or not containing impurities.
Arsenic Metal (99.999% Pure)
High-purity elemental arsenic metal (99.999%) in ingot or lump form, used for doping silicon wafers in semiconductor manufacturing. As a separate chemical element, it falls under tariff item 2804.80.00, provided it is not in a form already cut for electronics.
Elemental Arsenic Pieces (99.9% Purity)
Irregular pieces or chunks of elemental arsenic metal at 99.9% purity, used in alloy production and chemical synthesis. This is a separate chemical element, not a compound or mixture, and thus falls under tariff item 2804.80.00.
High-Purity Arsenic Granules for Semiconductors
Granular arsenic (purity >99.99%) in sealed ampoules, designed for vapor deposition in gallium arsenide semiconductor production. As elemental arsenic in a pure form, it falls under tariff item 2804.80.00, provided it is not doped or cut for electronics.
