Exporting Recycled Copper Scrap to the US — US Secondary Smelters

Recycled copper scrap is a critical feedstock for the US secondary copper smelting industry, which produces around 40% of the nation's refined copper from scrap rather than mined ore. As global copper demand grows—driven by electrification, renewable energy, and electric vehicles—US secondary smelters increasingly rely on imports of high-grade copper scrap to maintain production. Latin America, with its robust collection networks and proximity to the US market, has emerged as a key supply region for materials like No. 1 Bare Bright Copper, No. 2 Copper, and Berry/Copper solids. This page provides a comprehensive guide for Latin American suppliers and US buyers navigating the recycled copper scrap trade, covering specifications, supplier landscapes, procurement practices, certification requirements, pricing context, and how Coppermont facilitates these transactions.

Product Specifications and Grades Relevant to US Buyers

Recycled copper scrap is categorized by the Institute of Scrap Recycling Industries (ISRI) into standardized grades that US secondary smelters use to ensure consistent quality. The most commonly traded grades for smelting include ISRI Code 1000 (Bare Bright Copper), which consists of clean, uncoated, unalloyed copper wire and cable with a minimum copper content of 99.9%. This grade commands the highest price due to its purity and minimal processing requirements. ISRI Code 2000 (No. 1 Copper) includes clean copper wire and tubing with a minimum of 97% copper content, while ISRI Code 3000 (No. 2 Copper) allows for slightly lower purity—typically 94–96% copper—and may include soldered, coated, or tinned copper. Berry/Copper solids (ISRI Code 4000) encompass clean copper solids like sheet, plate, and punchings with 95% copper content. US secondary smelters also accept Copper Mill Berry (ISRI Code 5000), which includes clippings and punchings from copper fabricating mills with a minimum of 98% copper. Each grade must be free from excessive insulation, iron, dirt, or other contaminants, as impurities increase smelting costs and reduce yield. ASTM B115-22, the standard specification for copper cathode, also applies indirectly to scrap feed quality, as smelters must ensure their final product meets these specifications. Suppliers must sort, clean, and certify scrap according to ISRI standards to avoid rejection at US ports and maintain long-term buyer relationships.

LATAM and Africa Supplier Landscape for Recycled Copper Scrap

Latin America is a major source of recycled copper scrap for the US, with Mexico, Chile, Peru, and Brazil leading production. Mexico alone exported over 300,000 metric tons of copper scrap to the US in 2023, according to USITC data [1], driven by its proximity, established recycling infrastructure, and free trade agreement under USMCA. Chilean scrap exports to the US have grown steadily, with volumes reaching approximately 50,000 metric tons in 2023, supported by the country's large copper mining sector and expanding urban recycling programs [2]. Peru and Brazil collectively supply another 60,000–80,000 metric tons annually, though their exports are more variable due to logistical challenges and domestic demand. In Africa, South Africa and Egypt are emerging suppliers, with South Africa exporting around 20,000 metric tons of copper scrap to the US in 2023, primarily No. 2 Copper and Berry/Copper solids [3]. However, African scrap often faces higher freight costs, longer lead times, and regulatory hurdles related to hazardous waste classification under the Basel Convention. The US secondary smelter market is concentrated in the Midwest and Southeast, with major buyers including Aurubis Richmond, Southwire, and Tri-State Metals, all of which maintain strict quality control and environmental compliance programs. Latin American suppliers benefit from shorter shipping times (3–7 days via ocean freight from Mexico or Central America versus 20–30 days from Africa) and lower logistics costs, making them preferred partners for US buyers seeking reliable, high-volume scrap supply.

US Buyer Types—Who Buys Recycled Copper Scrap and How They Procure

US secondary smelters are the primary buyers of recycled copper scrap, processing it into refined copper cathode, copper rod, and other semi-finished products. Major smelters like Aurubis Richmond (California), Southwire (Georgia), and Tri-State Metals (Kentucky) operate large-scale facilities that consume tens of thousands of metric tons of scrap annually. These buyers typically procure scrap through long-term contracts with established suppliers, supplemented by spot purchases to balance inventory. The procurement process begins with supplier qualification, which includes audits of sorting and processing facilities, review of ISRI certification documentation, and testing of sample shipments for purity and contamination. Buyers specify grade requirements, moisture limits (typically below 2%), and maximum allowable levels of lead, tin, and iron. Payment terms commonly range from 30 to 60 days after delivery and inspection, with pricing based on LME copper cathode prices minus a discount (or “smelter charge”) that reflects processing costs and grade quality. For example, No. 1 Bare Bright Copper might trade at LME minus 5–10 cents per pound, while No. 2 Copper trades at a larger discount of 20–30 cents per pound. US buyers also prioritize suppliers with strong environmental, social, and governance (ESG) credentials, as downstream customers increasingly demand sustainably sourced materials. This has led to a preference for suppliers who can document their scrap collection and processing practices, including chain-of-custody certifications and compliance with US import regulations.

Certifications and Import Requirements for Recycled Copper Scrap

Exporting recycled copper scrap to the US requires compliance with several federal regulations and industry standards. The US Environmental Protection Agency (EPA) regulates copper scrap under the Resource Conservation and Recovery Act (RCRA), which classifies non-hazardous scrap as exempt from hazardous waste rules if it is destined for recycling and meets certain purity thresholds. However, scrap containing lead, cadmium, or other contaminants above regulatory limits may be classified as hazardous, triggering additional paperwork and disposal restrictions. Importers must file an EPA Notification of Intent to Export (NOIE) for shipments exceeding certain thresholds, and the scrap must be accompanied by a manifest detailing its composition and destination. The US Customs and Border Protection (CBP) requires a commercial invoice, packing list, bill of lading, and ISRI certification for each shipment, along with a certificate of origin under the USMCA (for Mexican scrap) or general tariff preferences. The LME provides daily pricing benchmarks that influence contract terms, though it does not directly regulate scrap trade. Additionally, many US buyers require suppliers to hold ISO 14001 certification for environmental management or R2 (Responsible Recycling) certification, which demonstrates adherence to global recycling standards. The Basel Convention, which restricts transboundary movements of hazardous waste, does not typically apply to clean copper scrap destined for recycling, but African exporters must verify that their scrap qualifies as non-hazardous under the convention to avoid shipment delays. Suppliers should work with experienced customs brokers and legal advisors to navigate these requirements and ensure smooth entry into the US market.

Pricing and Lead Time Context

Pricing for recycled copper scrap in the US market is primarily driven by LME copper cathode futures, which have traded in a range of $3.50–$4.50 per pound over the past year. The spread between LME cathode and scrap prices varies by grade: No. 1 Bare Bright Copper typically commands 95–97% of LME, while No. 2 Copper trades at 88–92% of LME, reflecting higher processing costs for lower-purity material [4]. Berry/Copper solids generally fall between these ranges at 92–95% of LME. Freight costs from Latin America to US Gulf Coast ports add $0.05–$0.15 per pound, depending on volume and shipping distance, while African scrap faces higher freight costs of $0.10–$0.25 per pound due to longer routes and port congestion in Durban or Alexandria. Lead times from Latin America are typically 2–4 weeks from order to delivery, including sorting, container loading, ocean transit (3–7 days), and customs clearance. African shipments require 6–10 weeks, given longer transit times and potential delays at origin ports. US buyers often negotiate contracts with quarterly price resets based on LME averages, with volume discounts for shipments exceeding 500 metric tons per month. Spot purchases may include premiums of 2–5% above contract prices for immediate delivery. Currency risk is minimal for Latin American suppliers who invoice in US dollars, but African exporters must hedge against exchange rate fluctuations if using local currencies. Overall, the recycled copper scrap market remains tight, with global demand expected to grow 3–5% annually through 2030, supporting stable pricing for high-quality suppliers [5].
