Products classified under Tariff item 2843.10.00.00
Colloidal Gold Diagnostic Reagent
A bulk colloidal gold reagent consisting of gold nanoparticles suspended in a liquid, imported before any conjugation with antibodies. It is a colloidal precious metal, as the gold particles are finely dispersed in the medium, falling squarely under tariff item 2843.10.00.
2843.10.00Colloidal Gold Ink for Electronics
A bulk colloidal gold ink containing gold nanoparticles dispersed in a solvent, used for printing conductive circuits. It is a colloidal precious metal because the gold is in colloidal form, not yet printed onto any substrate, and is classifiable under this tariff item.
2843.10.00Colloidal Gold Solution
A stable suspension of gold nanoparticles in water or another solvent, used in diagnostics and nanotechnology. The product consists of gold in colloidal form, meeting the definition of colloidal precious metals under this tariff item.
2843.10.00Colloidal Palladium Solution
A stable liquid colloid of palladium nanoparticles used in catalysis and electronics. Palladium is a precious metal, and its colloidal dispersion falls under this tariff item as a colloidal precious metal.
2843.10.00Colloidal Platinum Catalyst Precursor
An ethanol dispersion of platinum nanoparticles intended for depositing onto fuel cell electrodes. The platinum is in colloidal form, making it a colloidal precious metal under this tariff item.
2843.10.00Colloidal Platinum Dispersion
An aqueous suspension of platinum nanoparticles used as a catalyst in chemical reactions and fuel cells. The platinum is in colloidal form, and the product is classifiable as a colloidal precious metal under this tariff item.
2843.10.00Colloidal Silver Nanoparticles
A water-based colloid of silver nanoparticles used for antimicrobial treatments in textiles. Silver is a precious metal, and the colloidal form falls under this tariff item.
2843.10.00Colloidal Silver Suspension
A liquid dispersion of silver nanoparticles for antimicrobial applications in supplements and wound dressings. The silver is in colloidal form, making it a colloidal precious metal under this tariff item.
