Bismuth ingot 99.99% price

For high-purity Bismuth (4N), you must verify the Chemical Composition Analysis provided by the supplier. Ensure the Bismuth content is ≥99.99%, with specific limits on impurities such as Lead (Pb), Copper (Cu), Silver (Ag), and Antimony (Sb), which should typically be below 0.001% to 0.005% depending on the application. Request a Certificate of Analysis (COA) for every batch to ensure consistency in metallurgical properties.

Bismuth ingots of this purity are primarily used in the production of low-melting-point alloys, fusible alloys, and as a non-toxic replacement for lead in plumbing fixtures and fishing weights. It is also a critical raw material in the pharmaceutical industry for bismuth subsalicylate, the cosmetics industry for bismuth oxychloride (pearlescent pigment), and in semiconductor research due to its unique thermoelectric properties.

The ingots should have a bright, metallic luster with a slight pinkish tinge; a dull or heavily oxidized surface may indicate poor storage or lower purity. Standard ingots usually weigh between 10kg to 15kg. For cross-border shipping, ensure they are packed in seaworthy wooden crates or reinforced pallets with steel strapping, as Bismuth is brittle and can break under heavy impact.

Suppliers should adhere to ASTM B898 or equivalent national standards like GB/T 915-2010. Since Bismuth is often used as a 'green' metal, ensure the supplier provides RoHS and REACH certification to prove the absence of hazardous substances, especially if the end product is destined for the European or North American markets.

Bismuth is a minor metal with prices influenced by global mining output and industrial demand. To mitigate risk, monitor the minor metal exchange prices regularly and consider long-term supply contracts with fixed price windows.

Always use Secure Payment services provided by the platform to ensure funds are only released upon proof of shipment. For large volumes, insist on a third-party inspection (such as SGS or Intertek) at the loading port to verify the weight and purity before the final balance is paid. This prevents 'short-weighting' or receiving sub-standard material.

Bismuth is generally classified under HS Code 8106.00. Ensure the supplier provides a detailed Packing List, Commercial Invoice, and Bill of Lading. Because it is a heavy metal, freight costs are calculated by weight; compare FOB and CIF terms to see if the supplier’s shipping lines offer better rates than your local forwarder. Be aware of any export duties or environmental taxes applicable in the country of origin.

Focus on volume-based pricing tiers; for Bismuth, a 1-ton order will have a significantly different unit price than a 100kg sample. Inquire about the lead time for refined production, as high-purity ingots may not always be in stock. Establishing a strategic partnership by sharing your annual projected volume can help you secure priority allocation during periods of tight supply.
