cadmium price

Cadmium is predominantly used in the production of Ni-Cd batteries, although its use in consumer electronics is declining. It remains critical for industrial coatings (electroplating) to prevent corrosion in aerospace and marine environments, as a stabilizer in PVC plastics, and in the manufacturing of high-performance pigments (yellow, orange, red) for glass and ceramics. Additionally, it is used in thin-film solar cells (Cadmium Telluride) and specialized low-melting-point alloys.

Buyers must specify the purity level, typically ranging from 99.9% (3N) to 99.999% (5N) depending on the application. For semiconductor or solar use, high-purity ingots are required. You should also define the physical form (ingots, balls, sticks, or powder) and request a Certificate of Analysis (COA) that details the maximum allowable limits of impurities like Copper (Cu), Lead (Pb), and Iron (Fe).

As a heavy metal, Cadmium is strictly regulated. You must ensure compliance with REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) for the EU market and RoHS (Restriction of Hazardous Substances) for electronics. Suppliers must provide a comprehensive Safety Data Sheet (SDS/MSDS). Because it is classified as a toxic and hazardous substance, packaging must meet UN-certified dangerous goods standards to prevent environmental leakage during transit.

The price is generally indexed to global metal exchange rates (such as the LME) but is heavily influenced by purity and volume. Bulk industrial grade (99.95%) is priced per metric ton, while high-purity lab grade is priced per kilogram. Buyers should look for FOB (Free On Board) pricing from established industrial hubs to minimize domestic logistics costs within the sourcing country.

The primary risks include regulatory seizure due to improper documentation and quality inconsistency where the purity does not match the COA. To mitigate this, use third-party inspection services (like SGS or Intertek) to verify the chemical composition before the final balance payment is made. Always source from verified manufacturers on Made-in-China.com who have a proven track record of exporting hazardous materials.

Focus on price formulas linked to market indices rather than fixed prices to account for market volatility. Negotiate tiered pricing where the unit cost drops as your annual volume increases. For security, request Trade Assurance or Letter of Credit (L/C) payment terms to ensure the supplier meets all shipping and quality milestones before funds are released.

Cadmium is classified as a Class 6.1 Toxic Substance. Shipping requires specialized freight forwarders experienced in 'Dangerous Goods' (DG) handling. You must ensure the supplier provides a Dangerous Goods Declaration and uses moisture-proof, vacuum-sealed packaging inside reinforced wooden crates. For sea freight, ensure the container is positioned in a cool, ventilated area away from food products or reactive chemicals.

Verify the supplier's Export License for Hazardous Chemicals. Conduct a factory audit or request a video inspection of the production line and warehouse. Utilize the secured payment systems on Made-in-China.com to protect your capital. Avoid suppliers who insist on 100% upfront wire transfers via non-corporate accounts, as this is a high-risk indicator for fraud.
