Cadmium ingot 99.9 price manufacturers

When sourcing Cadmium Ingots, the 99.9% purity level (3N) is the standard benchmark. You must request a Chemical Composition Analysis or a Certificate of Analysis (COA) to ensure impurity levels for elements like Lead (Pb), Iron (Fe), Copper (Cu), and Zinc (Zn) do not exceed the maximum thresholds (typically <0.01% each). Additionally, verify the physical form (standard ingots usually weigh between 5kg to 20kg) and ensure the surface is free from oxidation, slag, or mechanical inclusions.

Cadmium 99.9% is primarily used in the production of Ni-Cd rechargeable batteries, anti-corrosion electroplating for the aerospace and marine industries, and as a key component in low-melting-point alloys (fusible alloys). It is also a critical precursor for pigments (Cadmium Yellow/Red) and stabilizers in plastics. For high-tech applications like solar cells (CdTe), buyers may need to inquire if the supplier can provide higher purity levels (99.99% or 99.999%).

Cadmium is a heavy metal and a hazardous substance. Suppliers must provide a comprehensive Material Safety Data Sheet (MSDS). For international trade, ensure the product complies with REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) if exporting to Europe, and check for RoHS compliance if the end-use involves electronics. Because it is toxic, the packaging must be airtight and clearly labeled with hazardous material symbols.

The price of Cadmium is highly sensitive to global zinc mining output (as it is a byproduct) and environmental regulations in the manufacturing country. To ensure economic feasibility, buyers should monitor the LME (London Metal Exchange) or specialized metal bulletins. It is advisable to negotiate long-term supply contracts with a formula-based pricing model to mitigate the risk of sudden market volatility.

Cadmium is classified under UN Number 2570 (Cadmium Compounds) or as a toxic solid depending on the form. It requires Class 6.1 Toxic Substance packaging. You must ensure your freight forwarder is certified to handle Dangerous Goods (DG). For shipping from China, verify that the supplier has the 'Identification and Classification Report for Air/Sea Transport of Goods' to avoid customs delays or impoundment.

Given the high value and regulated nature of non-ferrous metals, use Made-in-China.com's 'Audited Supplier' reports to verify the manufacturer's production capacity and business license. Always use Secured Payment terms or a Letter of Credit (L/C) for large volumes. Never wire full payments to personal accounts; ensure the bank account name matches the registered corporate name on the platform.

Focus on volume-based discounts and purity consistency. Ask for a pre-shipment inspection (PSI) by a third party like SGS or Intertek to verify the weight and purity at the port of loading. Negotiate for flexible Incoterms; while FOB (Free On Board) is common, CIF (Cost, Insurance, and Freight) may be safer for buyers unfamiliar with hazardous material logistics, as the seller manages the complex DG documentation.

The primary risks include weight discrepancies and purity fraud. Some low-tier suppliers may mix scrap metal. To mitigate this, require batch-specific COAs and photos of the stamped heat numbers on the ingots. Additionally, be aware of export quotas or environmental 'Blue Sky' inspections in China, which can lead to sudden factory shutdowns and force-majeure delays.
