Aluminium scrap

When sourcing aluminium scrap, quality is determined by the purity levels and the presence of contaminants. Buyers should categorize scrap based on ISRI (Institute of Scrap Recycling Industries) codes, such as 'Tense' (mixed cast), 'Taint/Tabor' (clean sheet), or '6063 Extrusions'. It is critical to verify the chemical composition using XRF (X-ray fluorescence) analyzers to ensure the silicon, iron, and copper content meets your smelting or manufacturing specifications. High-quality scrap should have minimal attachments (plastic, rubber, or steel) and be free of excessive oxidation or moisture, which can lead to significant melt loss.

Compliance is the most critical factor in the scrap trade due to environmental regulations. Suppliers must provide a Certificate of Analysis (COA) and, depending on the destination, a Pre-Shipment Inspection Certificate (PSIC) issued by agencies like CCIC or SGS. Ensure the supplier adheres to ISO 9001 for quality management and ISO 14001 for environmental management. For cross-border trade, the scrap must comply with the Basel Convention regulations to ensure it is not classified as hazardous waste, and it must meet the specific import purity thresholds set by the destination country (e.g., China's GB/T standards for recycled aluminium).

To maximize ROI, buyers should focus on the yield rate (recovery rate) rather than just the sticker price; a lower-priced scrap with high contamination may result in higher processing costs. Negotiate pricing based on the LME (London Metal Exchange) Aluminium cash price with a fixed discount or 'spread.' Consider logistics optimization by sourcing 'baled' or 'briquetted' scrap to maximize container weight utilization, as shipping air in loose scrap significantly increases the Total Cost of Ownership (TCO).

The most prevalent risk is material substitution or 'weight loading', where inferior materials or heavy waste are hidden in the center of the container. To mitigate this, always mandate a third-party loading supervision and use secure payment methods like Letter of Credit (L/C) or escrow services. Avoid suppliers who demand 100% upfront T/T payments, especially for first-time orders. On Made-in-China.com, prioritize Audited Suppliers who have undergone on-site verification of their facilities and business licenses.

Shipping scrap requires precise documentation to avoid customs seizures or heavy fines. Ensure the HS Code (typically 7602.00) is correctly declared. Buyers must be aware of export duties in the origin country and import quotas in their own. It is highly recommended to use CIF (Cost, Insurance, and Freight) terms only if you trust the supplier's logistics; otherwise, FOB (Free On Board) allows you to control the shipping line and ensure the container is not diverted. Always verify if the supplier has an export license for metal waste, as many countries have restricted the outflow of raw materials.

Conduct a digital audit of the supplier by checking their years of operation and transaction history on Made-in-China.com. Request references from previous international buyers and verify their VAT registration. For large-scale contracts, consider a performance bond or a trial order of 1-2 containers before committing to long-term high-volume contracts. Ensure the contract clearly defines claims procedures for weight shortages or quality deviations exceeding 1-2%.
