U.S. exports of unwrought thallium; powders (HS 811251) totaled $3K in April 2026, traded with 1 country.
Last updated: April 2026 dataThallium in unwrought form and as powder is a specialty metal with niche applications in infrared optics, low-temperature thermometers, and certain semiconductor research contexts. Classified under a single 10-digit line (8112510000), this heading covers primary and semi-processed thallium before any fabrication into articles. Thallium's acute toxicity means that handling, labeling, and waste-disposal requirements under EPA and OSHA regulations are significant compliance considerations for importers and downstream users, independent of customs classification.

Yes. Thallium is classified as a hazardous substance under EPA regulations due to its high toxicity. Importers must comply with applicable EPA reporting thresholds, OSHA hazard communication standards, and DOT hazardous materials transport rules. Proper Safety Data Sheets and packaging declarations are required at entry.
Unwrought thallium refers to the metal in its primary forms — ingots, slabs, lumps, or powder — that have not been shaped into a specific article by further working. Once thallium is drawn into wire, rolled into sheet, or machined into a component, it would move to the NESOI articles heading (811259) rather than this unwrought heading.
