Copper scrap wire price manufacturers

The price is primarily indexed to the London Metal Exchange (LME) or COMEX spot prices. Buyers should look for quotes expressed as a percentage of the LME copper price (e.g., 92%-95% LME). The final price depends on the copper content (purity), with Millberry (99.9%) fetching the highest value, followed by Berry/Candy and Birch/Cliff grades.

Copper scrap is categorized by purity: No. 1 Bare Bright Copper Wire (unalloyed, uncoated, 16 gauge or thicker) is the most premium. No. 2 Copper Wire usually contains 94-96% copper and may have tin or shellac coatings. For industrial sourcing, ensure the supplier specifies the ISRI (Institute of Scrap Recycling Industries) code to avoid ambiguity in quality expectations.

International trade of scrap metal is strictly regulated. You must ensure the supplier provides a CCIC (China Certification & Inspection Group) certificate for shipments to China, or equivalent pre-shipment inspection reports for other regions. The material must be free of hazardous contaminants, excessive moisture, and radioactive materials to pass customs under the Basel Convention guidelines.

Professional buyers should request an SGS or Alex Stewart inspection report. Key metrics include chemical composition analysis (spectroscopy) and recovery rate tests. For large-scale procurement, it is standard practice to base the final invoice on the outturn weight and quality report issued by a recognized third-party surveyor at the port of discharge.

Be wary of prices significantly below the LME market rate; if a deal seems too good to be true, it usually is. A common scam involves 'bait and switch', where the top layer of a container is high-quality copper while the rest is bricks, slag, or low-grade iron. Always use Made-in-China.com's Secured Trading services and avoid direct wire transfers to unverified personal accounts.

Never pay 100% upfront. The safest industry standard is a Letter of Credit (L/C at sight) or a Telegraphic Transfer (T/T) split, such as 20% deposit and 80% payable after the presentation of the Bill of Lading and SGS Inspection Report. Using an Escrow service provided by reputable B2B platforms can significantly mitigate the risk of non-delivery.

Copper scrap is high-density and high-value. Use 20ft containers to stay within weight limits while maximizing value. Ensure the supplier uses heavy-duty liners to prevent moisture damage. For international trade, CIF (Cost, Insurance, and Freight) is common, but FOB (Free On Board) gives the buyer more control over the shipping line and prevents hidden 'destination charges'.

Prices are sensitive to export duties in the country of origin and import quotas in the destination country. For example, China has strict purity thresholds (e.g., GB/T 38471-2019) for recycled copper raw materials. Always verify if your specific scrap grade is classified as 'solid waste' (prohibited) or 'recycled resource' (allowed) to avoid customs seizures and heavy fines.
