Zinc ingot shg

Zinc Ingot SHG must meet a purity level of at least 99.995%. Buyers should verify the chemical composition, ensuring that impurities like Lead (Pb) < 0.003%, Iron (Fe) < 0.003%, and Cadmium (Cd) < 0.003% are strictly controlled. The standard weight per ingot typically ranges from 20kg to 25kg, though jumbo blocks (approx. 1 ton) are available for large-scale industrial use.

The most recognized standards are ASTM B6-18 (Standard Specification for Zinc) and BS EN 1179:2003. Ensure the supplier is ISO 9001 certified for quality management and ISO 14001 certified for environmental management. For exchange-traded goods, check if the brand is LME (London Metal Exchange) registered, which guarantees a globally accepted quality benchmark.

SHG Zinc is primarily used in Hot-Dip Galvanizing to protect steel from corrosion, Die-Casting alloys (such as Zamak) for automotive and electronics components, and the production of Brass and Bronze. Its high purity is essential for electroplating and the manufacturing of Zinc Oxide used in rubber and pharmaceutical industries.

Always request a Certificate of Analysis (COA) for every heat number/batch. For high-value B2B transactions, it is highly recommended to appoint a third-party inspection agency like SGS or Intertek to perform spectrographic analysis and verify the weight and quantity at the loading port.

Zinc is a globally traded commodity with prices fluctuating daily based on the LME (London Metal Exchange). Buyers should negotiate a pricing formula (e.g., LME Cash Price + Premium) rather than a fixed price for long-term contracts. Using Made-in-China.com's secured payment services can help mitigate financial risks during price swings.

Zinc ingots are heavy and dense; they must be securely strapped with steel bands on pallets or in bundles. Ensure the supplier uses seaworthy packaging to prevent oxidation from salt air. For shipping to specific regions, confirm the Harmonized System (HS) Code 790111 is used correctly to avoid customs delays and ensure accurate import duty calculation.

Conduct a factory audit or use the 'Audit Finished' supplier verification service on Made-in-China.com. Never transfer full payments upfront to unverified accounts; utilize Letters of Credit (L/C) or Escrow-based payment terms to ensure funds are only released upon presentation of the Bill of Lading (B/L) and inspection reports.

Buyers must stay informed about export rebates or export duties imposed by the origin country. For instance, changes in Chinese environmental policies can impact production output and export quotas. Always clarify Incoterms (typically FOB or CIF) to define exactly where the risk transfers and who covers the ocean freight and insurance.
