Aluminium ubc cans scrap

High-quality UBC scrap must adhere to the ISRI (Institute of Scrap Recycling Industries) specifications, specifically the 'Talc' grade. This requires the scrap to be free of excessive dirt, liquid, other metals, and non-metallic contaminants like plastic or glass. The aluminium content should typically be 99% or higher after the removal of coatings and moisture. Buyers should verify that the scrap is baled with a density of 14 to 25 pounds per cubic foot to optimize shipping costs and furnace efficiency.

Since UBC scrap is a secondary raw material, you must request a Chemical Composition Analysis (Spectroscopy report). Key elements to monitor include Magnesium (Mg) and Manganese (Mn), which are standard in 3000-series alloys used for cans. Ensure the attachment level (moisture, paint, and plastic) does not exceed 2-5%, as higher levels lead to significant 'melt loss' during smelting, directly impacting your ROI.

Suppliers must provide an AQSIQ certificate if shipping to certain Asian markets, and generally, an ISO 14001 certification is preferred to ensure environmentally sound management. Ensure the supplier complies with the Basel Convention regulations regarding the transboundary movement of hazardous waste, although clean aluminium scrap is usually classified as non-hazardous. Always request a Certificate of Origin and a Pre-shipment Inspection Certificate (such as SGS or CCIC) to confirm the weight and quality before the balance payment.

UBC scrap is primarily traded in three forms: Baled (compressed blocks for easy handling), Briquetting (high-density small blocks), and Shredded (loose pieces with magnetic separation already performed). Baled UBC is the most common for cross-border trade due to the balance between processing cost and shipping density. For large-scale industrial smelters, shredded and de-coated scrap is preferred as it reduces energy consumption during the melting process.

Scrap metal is a high-risk category for fraud. Never rely solely on photos or videos, which can be easily faked. Use third-party inspection services like SGS or Intertek to conduct a 'Loading Supervision' where they verify the material as it is placed into the container. For new suppliers on Made-in-China.com, prioritize 'Audited Suppliers' who have undergone on-site factory/warehouse inspections by independent third parties.

Avoid 100% T/T (Telegraphic Transfer) upfront. The industry standard for secure transactions is a Letter of Credit (L/C) at sight or Escrow services. If using T/T, a common safe structure is 30% deposit and 70% against the presentation of the Bill of Lading (B/L) and the CCIC/SGS inspection report. This ensures the supplier only receives the bulk of the payment after the goods are verified and shipped.

Due to the heavy nature of aluminium scrap, CIF (Cost, Insurance, and Freight) is often preferred by buyers to simplify logistics, but FOB (Free On Board) gives you more control over the shipping line and costs. Be aware of 'Demurrage' and 'Detention' charges at the destination port; ensure your contract allows for at least 14-21 days of free time to account for potential customs delays or inspection hold-ups.

Aluminium prices are tied to the LME (London Metal Exchange). Professional suppliers usually quote based on 'LME +/ - a fixed premium/discount'. Ensure your contract specifies the pricing formula and the specific date of the LME fix to avoid disputes if the market price shifts significantly between the order date and the shipping date.
