Ubc scrap

The primary standard for UBC Scrap is the ISRI (Institute of Scrap Recycling Industries) specification, specifically the 'RWI' (Relat) or 'Tally' grades. Buyers must ensure the scrap has a minimum aluminum content of 99% (after decoating) and a maximum moisture/attachment limit of 5%. It is essential to verify that the scrap is free from excessive dirt, plastic, glass, and other non-metallic contaminants to prevent yield loss during smelting.

UBC Scrap is typically traded in baled, briquetted, or shredded forms. Baled UBC should have a density of at least 14 lbs per cubic foot to optimize shipping container space. For high-volume industrial buyers, shredded and magnetically separated scrap is preferred as it reduces processing time. Ensure the packaging uses high-tensile steel strapping to prevent bale expansion during transit, which can damage container walls.

Suppliers must provide an AQSIQ certificate (if shipping to specific Asian markets) and a Certificate of Origin. Because scrap metal is often classified under 'waste' regulations, ensure the supplier complies with the Basel Convention on transboundary movements of hazardous wastes. Look for suppliers with ISO 14001 (Environmental Management) and ISO 9001 (Quality Management) to ensure ethical and standardized recycling processes.

Before full payment, request a third-party inspection report (e.g., SGS or CCIC). This report should confirm the chemical composition (Al-Mg-Mn alloys) and the recovery yield percentage. A professional supplier should provide a representative sample analysis showing that the scrap is free from 'heavy' metals like lead or cadmium, which can contaminate the final aluminum melt.

The most significant risk is 'Quality Substitution' or 'Weight Fraud', where the center of the bale contains heavy waste or moisture to increase weight. To mitigate this, use Made-in-China.com's secured payment services and mandate a pre-shipment inspection (PSI). Never pay 100% upfront; a standard 30/70 T/T or Letter of Credit (L/C) at sight is recommended for large-scale scrap trades.

UBC Scrap is usually shipped in 20ft or 40ft HC containers. Ensure the Incoterms are clearly defined (FOB or CIF). Buyers should confirm that the shipping line allows 'Scrap Metal' cargo, as some carriers have strict fire-safety protocols for aluminum fines. Always secure Marine Cargo Insurance that covers 'All Risks' to protect against loss or contamination during sea transit.

Pricing for UBC Scrap is usually pegged to the LME (London Metal Exchange) Aluminum Index minus a percentage (the 'discount'). Negotiate based on the recovery yield; if the yield is lower than 90%, the price per ton should decrease proportionally. Establish a long-term contract to secure stable supply, as the scrap market is highly volatile and subject to seasonal supply fluctuations.

Always verify the supplier's business license and export permit for scrap metal. Utilize the Audit Reports available on Made-in-China.com to check the supplier's factory capacity and historical export data. For the first order, consider a trial shipment of one container to verify that the actual material matches the provided chemical analysis and photos.
