Cadmium metal ingot - one troy ounce - .9999 bullion Cadmium was discovered in Germany in 1817, separately by two Germans, one a physician (Friedrich Stromeyer) and the other a chemist (K.S.L. Hermann). It makes up only about 0.1 ppm of the Earth's crust and is produced largely as a byproduct from zinc ore. Cadmium has numerous industrial uses, but has been used less prevalently since the 1980s when concerns over its toxicity began to grow. Cadmium has been used as a coating to make iron and steel corrosion resistant; as a stabilizer of plastics; in batteries, nuclear controls rods, semiconductors, and solar panels. Its sulfides and selenides make intense red, orange, and yellow pigments. Inscribed on these ingots are the chemical symbol (Cd), purity (99.99%), weight (one troy ounce), and a serial number (this number is unique and will vary). On the reverse is our logo. These ingots are lightly polished, similar to the one pictured. There can be tiny edge dings, light surface scratches, light edge grooves and other small imperfections. Weight and purity are guaranteed by Rare World Metals Mint. Cadmium is considered toxic and carcinogenic. Inhalation or injection, particularly of fine particles or ignited fumes of cadmium are the greatest threats and can result in acute pulmonary edema, severe chronic lung damage, permanent loss of smell, and even death. As we suggest with all of our metals please keep these ingots intact and in a safe place, do not ingest, and keep out of the reach of children. Handling our cadmium ingot with gloved hands isn't required, but not a bad idea. Hand washing after handling is suggested. If you follow this advice, then owning your very own solid ingot of cadmium should be of little risk. Each ingot will be shipped with an assay certificate and every shipment will include our velvet logo bag. If you are not completely satisfied with any purchase from us, you have 30 days to return it for a full refund (buyer to pay return shipping).

If you are unsure what these import costs will be please check with your country's customs office. https://en.wikipedia.org/wiki/Cadmium http://en.wikipedia.org/wiki/Abundance_of_elements_in_Earth%27s_crust https://nora.nerc.ac.uk/id/eprint/513472/1/Risk_List_2015_FINAL.pdf
