8106.10.00High-Purity Bismuth Metal Ingot
A cast ingot of bismuth metal refined to exceed 99.99% purity by weight, used primarily in alloys and electronics manufacturing. This unwrought form falls under the tariff item due to its exceptional bismuth content.
8106.10.00Pharmaceutical Bismuth Powder 99.99%
Fine powder of >99.99% bismuth for use in pharmaceutical intermediates and contrast agents. This high-purity unwrought powder is specifically covered by the tariff item due to its metal content exceeding the chapter's purity threshold.
8106.10.00Ultra-Pure Bismuth Granules
Granular bismuth metal at >99.99% purity, supplied for laboratory and pharmaceutical synthesis where minimal impurities are critical. This form is unwrought and directly matches the tariff item for its defined high bismuth content.
8106.90.00Bismuth Alloy Low-Melt Casting Rods
Bismuth-based low-melting alloy rods (e.g., Cerrolow 117) used for fusible plugs, fire sprinkler triggers, and metal crafting. They are classified as 'other' articles of bismuth under tariff item 8106.90.00 because bismuth is the predominant metal by weight, and they are not unwrought, powders, or waste/scrap.
8106.90.00Bismuth Anode for Electroplating
Cast bismuth anodes used in electroplating baths for corrosion-resistant coatings in marine and automotive applications. These are fabricated articles of bismuth, not unwrought or powder, and thus fall under tariff item 8106.90.00 as 'other' articles.
8106.90.00Bismuth Block for Lab Weights
Precision-machined bismuth blocks used as calibration weights in analytical balances. They are fabricated articles of bismuth, valued for their density and non-magnetic properties, and are classified under tariff item 8106.90.00 as 'other' articles.
8106.90.00Bismuth Crystals for Education
Laboratory-grown bismuth crystals for science education and decorative purposes. These are fabricated articles showcasing bismuth's crystal structure, classified under tariff item 8106.90.00 as 'other' articles, not as unwrought metal or powder.
8106.90.00Bismuth Foil for Radiation Shielding
Thin bismuth foil sheets used for radiation shielding in X-ray aprons and medical imaging collimators. These are fabricated articles of bismuth, classified under tariff item 8106.90.00 as 'other' articles due to their specific form and use.
8106.90.00Bismuth Granules for Pharmaceuticals
Granulated pure bismuth (over 99.99% purity) for pharmaceutical compounding in peptic ulcer treatments. These granules are processed from ingots and are classified under tariff item 8106.90.00 as 'other' articles, excluding unwrought forms and powders.
8106.90.00Bismuth Pebbles for Jewelry Casting
Small bismuth pebbles used by jewelers for low-melt casting molds and artistic ingots. These are fabricated articles of bismuth, classified under tariff item 8106.90.00 as 'other' articles, known for their iridescent crystal patterns.
8106.90.00Bismuth Pellets for Shotgun Loads
Sized bismuth pellets for non-toxic shotgun ammunition, replacing lead shot for waterfowl hunting. These are fabricated articles of bismuth, classified under tariff item 8106.90.00 as 'other' articles, not as unwrought metal.
8106.90.00Bismuth Powder for Cosmetics
Micronized bismuth oxychloride powder used as a pearlescent pigment in cosmetics. Although it is a powder, it is a processed article of bismuth, not a base metal powder, and falls under tariff item 8106.90.00 as 'other' articles.
8106.90.00Bismuth Ring Weights for Fitness
Annular bismuth rings used as stackable weights for ankle and wrist fitness bands. These are fabricated sporting articles of bismuth, classified under tariff item 8106.90.00 as 'other' articles, valued for their density and corrosion resistance.
8106.90.00Bismuth Sheet for Art Sculpture
Hammered bismuth sheets for contemporary sculpture and wall art, leveraging bismuth's natural iridescence. These are fabricated artistic articles of bismuth, classified under tariff item 8106.90.00 as 'other' articles.
8106.90.00Bismuth Shot for Fishing Sinkers
