Import Tips & Compliance
• Confirm thallium is the predominant metal by weight
• Provide alloy composition data to customs
• Check if the bars meet the definition of bars and rods under chapter notes
Related Products under Tariff item 8112.59.00
Thallium Alloy Wire
Thallium alloy wire, specifically a thallium-lead alloy, used in specialized solders for high-tech applications. This product is classified as 'other' articles of thallium under tariff item 8112.59.00, as it is a fabricated article rather than unwrought metal or waste.
Thallium Calibration Weights
Precision-machined thallium weights used for density calibration in metrology laboratories. These are fabricated articles of thallium, not covered by other specific headings, and thus fall under tariff item 8112.59.00 as 'other' thallium articles.
Thallium-Doped Glass Rods
Thallium-doped glass rods used in scintillator applications for radiation detectors. The rods derive their principal value from the thallium metal content, which classifies them as articles of thallium under tariff item 8112.59.00, rather than as glass products.
Thallium Evaporation Pellets
Small pellets of thallium used for vacuum evaporation in thin-film deposition processes for optics and semiconductors. These pellets are fabricated articles of thallium, distinct from unwrought forms, and are classified under tariff item 8112.59.00 as 'other' thallium articles.
Thallium Metal Ingots
Pure thallium metal ingots used in the production of low-melting alloys and electronics. These ingots are unwrought forms of thallium, but the tariff item 8112.59.00 covers 'other' articles of thallium, excluding unwrought forms, which are classified under a separate tariff item.
Thallium Reference Standard Foil
Ultra-pure thallium foil sheets used as calibration standards in analytical chemistry laboratories. These are flat-surfaced products of thallium, not in unwrought form, and are classified under tariff item 8112.59.00 as 'other' thallium articles.
