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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the glass rods are not principally valued for their thallium content
Glass rods of fused quartz or other silica are classified under Chapter 70 when they do not derive their essential character from thallium.
If the rods are considered waste or scrap of thallium
Thallium waste and scrap are classified under a different tariff item within the same heading.

The Tariff Assistant works through the GRI rules on your specific product to reach the right tariff item — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Ensure the thallium content is documented to substantiate classification as an article of thallium
• Verify whether the rods qualify as 'other' articles under 8112.59.00 or if they might be considered glass articles under Chapter 70
• Keep records of the product's composition and use for CBSA verification
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 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.
Thallium Research Foil Sheets
Thin foil sheets of thallium used for superconductivity and materials science research. These are fabricated articles of thallium, not falling under other specific headings, and are classified under tariff item 8112.59.00 as 'other' thallium articles.
