Birch Cliff Copper Scrap (Grade 1): High-Quality Recycled Copper for Refining

Birch Cliff Copper Scrap (Grade 1) is one of the most in-demand categories of copper scrap in the global recycling and non-ferrous metal markets. It represents No. 2 copper wire, solids, and tubing that contain a high level of pure copper while allowing limited surface oxidation or minimal solder coating. Owing to its balance of quality and cost, this grade is the preferred feedstock for refineries, foundries, and brass manufacturers worldwide.

Composition and Quality Standard

The Birch Cliff classification follows the ISRI (Institute of Scrap Recycling Industries) specifications, which clearly define the acceptable limits for contamination and copper purity:

• Birch: No. 2 copper wire, generally 94–96 % pure, containing slight tarnish, lacquer, or coating but no burnt or brittle wires.

• Cliff: No. 2 copper solids and tubing, such as used copper pipes, connectors, or bus bars that may contain solder or minor impurities.

Both materials are free from excessive oil, grease, insulation, and non-metallic materials. These two categories are typically blended for shipment, forming the unified Birch/Cliff grade.

Production and Processing

Birch/Cliff copper scrap is mainly obtained from:

• Construction and plumbing industries: discarded copper tubes and fittings.

• Electrical and electronic sectors: outdated wiring, switches, and motor windings.

• Manufacturing and demolition waste: factory scrap, roofing materials, and household wiring.

After collection, the scrap undergoes mechanical sorting, granulation, density separation, and magnetic cleaning. Advanced sorting systems ensure removal of aluminum, steel, and other contaminants, bringing the product in line with ISRI quality requirements.

Applications

Because of its stable copper content and excellent remelting behavior, Birch Cliff scrap is widely used in:

• Copper refineries: as feedstock for electrolytic cathode production.

• Brass and bronze foundries: for alloying purposes.

• Wire rod plants: as part of secondary copper charge.

• Smelters and recyclers: where cost-efficient metal recovery is key.

This grade offers recyclers a reliable raw material that balances purity, availability, and pricing better than higher-priced No. 1 grades like Berry/Candy.

Export & Logistics

Birch Cliff copper scrap is commonly exported in 20- or 40-foot containers, loaded as loose bulk or compacted bales. Each shipment must comply with ISRI guidelines, radiation inspection, and pre-shipment quality control (PSI) to ensure that no prohibited materials (PVC, radioactive waste, or mixed metals) are included.

Typical shipping ports include Mersin, Jebel Ali, Mundra, and Antwerp, serving customers in Asia, the Middle East, and Europe. Standard documentation covers Certificate of Analysis (COA), Packing List, and Commercial Invoice aligned with HS code 7404.00.

Environmental and Economic Benefits

Using Birch Cliff copper scrap significantly reduces the carbon footprint compared to primary copper mining. Recycling copper consumes up to 85 % less energy and generates minimal waste, making this product a cornerstone of sustainable metal supply chains. For manufacturers, it provides a consistent source of copper units while controlling production costs amid market volatility.

Frequently Asked Questions (FAQ)

Q1: What is the difference between Birch/Cliff and Berry/Candy?
→ Birch/Cliff corresponds to No. 2 copper, which may contain slight impurities or oxidation, while Berry/Candy is No. 1 copper with ≥ 99 % purity.

Q2: What is the standard copper content of Birch/Cliff?
→ Typically between 94 % and 96 % Cu, depending on the source and cleaning process.

Q3: Can Birch Cliff scrap be used directly for electrical applications?
→ Not directly. It must first be refined into electrolytic copper cathodes or remelted for alloys.

Q4: How is Birch Cliff packed for export?
→ Usually in pressed bales or jumbo bags, loaded in 20- or 40-foot containers.

Q5: Why is Birch Cliff popular among smelters?
→ Because it provides high recovery rates, predictable chemistry, and lower cost than No. 1 grades.
