Aluminum scrap of cans

The most critical factor is the Aluminum Purity (typically 99% or higher) and the impurity level. Buyers must verify the moisture content (should be <1%), the presence of non-metallic attachments (plastics, paper, dirt), and the recovery rate after smelting. High-quality UBC scrap should be free of excessive oxidation and hazardous materials like lead or medical waste.

The industry standard is usually defined by the ISRI (Institute of Scrap Recycling Industries). For aluminum cans, the relevant code is 'Taldork' (baled UBC) or 'Taldeck' (shredded UBC). Ensuring the supplier adheres to ISO 9001 for quality management and ISO 14001 for environmental management is essential for long-term compliance and sustainability.

Aluminum scrap is typically offered in baled, briquetted, or shredded forms. Baled scrap is cost-effective for shipping but requires large-scale smelting facilities. Shredded scrap allows for easier mechanical separation of impurities but may have a higher surface area prone to oxidation loss during melting. Choose the form that matches your furnace charging system and logistics capabilities.

Professional buyers should demand a Chemical Composition Analysis (SGS or CCIC report). This report must detail the percentages of Silicon (Si), Iron (Fe), Copper (Cu), and Manganese (Mn). Additionally, request a Weight Bridge Ticket and loading photos to ensure the volume matches the invoice and that no 'heavy' contaminants are hidden in the center of the bales.

The scrap industry is high-risk for 'bait and switch' tactics, where the sample quality does not match the bulk shipment, or non-metallic waste is hidden inside bales to increase weight. To mitigate this, always use third-party inspections (SGS/CCIC) at the loading port and avoid suppliers who refuse Escrow payments or Letters of Credit (L/C).

Many countries have strict Green Fence or National Sword policies regarding solid waste. You must ensure the supplier provides a Certificate of Origin and that the scrap is classified correctly under HS Code 7602.00. Verify if your destination country requires a Pre-shipment Inspection Certificate and if the supplier is a registered exporter with your national environmental agency.

Aluminum scrap prices are usually pegged to the LME (London Metal Exchange) spot price. Negotiate a discount percentage off the LME price rather than a fixed price to account for market volatility. For shipping, CNF or CIF terms are common, but ensure the contract specifies 14 to 21 days of free time at the destination port to avoid heavy demurrage charges during customs clearance.

Utilize professional B2B platforms like Made-in-China.com, focusing on Audited Suppliers who have undergone on-site factory verification. Look for suppliers with a long history of exports and high transaction transparency. Always conduct a video factory audit to see the actual scrap yard and processing equipment before transferring any deposits.
