Industrial Copper Scrap
Driving the global circular economy. Supplying a comprehensive portfolio of high-grade copper scrap—from BERRY to CLIFF—engineered for immediate secondary smelting and seamless global export.
Recovering Value. Sustaining Industry.
SINCHI WAYRA SA sources, processes, and exports a vast portfolio of copper-bearing recyclable materials. Recovered from electrical systems, industrial manufacturing, and demolition, our copper scrap provides a critical, sustainable feedstock for global brass alloy and cathode production.
Our advanced mechanical sorting, stripping, and magnetic separation protocols guarantee that our premium grades—such as Bare Bright (BERRY) and No.1 Heavy Copper (CANDY)—meet the exacting purity and non-hazardous standards required for rapid China Customs clearance.

Maritime Export & Packaging Standards
A. Bales & Jumbo Bags
Optimized for transport density and container efficiency.
- Compressed Bales: 200–1000 kg blocks, hydraulically compressed and secured with steel straps.
- Jumbo Bags (FIBC): 1–2 MT woven polypropylene bags, utilized primarily for copper granules (CHOPS).
- Loose Loading: Direct bulk loading for large volume mixed scrap shipments.
B. Trade Classifications
Standardized coding for global transit.
- ISRI Standards: Strictly adhering to global scrap classification codes (BERRY, CANDY, CLIFF, etc.).
- HS Codes: 74040000 (Copper Waste/Scrap), 74040010 (Copper Wire Scrap).
- Compliance: Basel Convention Rules & China Environmental Import Standards.
C. Inspection & Pre-Clearance
Executed by BQCIS, CCIC, SGS, or BV.
- Hazard Checks: Strict radiation testing, foreign material inspection, non-hazardous declarations.
- Assay Verification: Copper purity, moisture testing.
- Container Loading: 20FT carrying 20–25 MT, requiring absolute dryness, odor-free status, and even distribution.
Export Documentation Requirements
Commercial Invoice • Packing List • Bill of Lading • Certificate of Origin • Certificate of Analysis (COA) • Weight Certificate • Inspection Certificate • Non-Hazardous Material Declaration • Radiation Free Certificate • Fumigation Certificate (if applicable).
Recovery & Processing Infrastructure
1. Scrap Beneficiation & Sorting
Raw materials are collected from electrical factories and demolition sites. We deploy advanced manual sorting, magnetic, and eddy current separation to remove iron and aluminum. Dedicated wire strippers and granulators eliminate insulation, producing clean, ready-to-melt copper feedstock.
2. Downstream Copper Refining
Our scrap serves as the critical energy-efficient feedstock for global secondary smelting and electrolytic refining:
- Smelting Recovery: CuO + C → Cu + CO
- Electrolytic Refining: Cu2+ + 2e− → Cu
- Yield: Direct pathway to LME-Grade Cathode and rod production.
Feeding the Industrial Engine.
By transforming mixed industrial waste into categorized, high-purity scrap commodities, SINCHI WAYRA SA provides a sustainable, high-yield feedstock alternative to major smelters in China, India, and South Korea.
