Bare Bright Copper
Clean, uncoated copper wire, #1 grade, 99%+ pure, no insulation
Certification Requirements
Required certifications, standards compliance, and verification protocols.
Copper collection, sorting, processing QMS
- Copper purity (≥99%)
- Lead content (Pb <0.05%) - CRITICAL
- Zinc (Zn <0.5%)
- Other contaminants
- Bare bright verification
- Independent lab certified
- Fire assay recommended for premium verification
Explicit statement: 'Bare Bright, No Insulation, Cu ≥99%, Barley/Berry Grade Confirmed'
- High-Value Material
- Precious Metal
Rejection Criteria
Conditions and thresholds that trigger immediate rejection or downgrading.
Any visible PVC, rubber, plastic insulation
IMMEDIATE FULL REJECTION
- Critical: Bare Bright Definition Requires No Insulation
- Insulated Wire = Different, Lower Grade
Cu <99.0%
Full rejection or reclassification to lower grade
- Grade Specification Violation
- Doesn'T Meet Barley/Berry Premium Requirement
Pb >0.05%
Full rejection (or major credit)
- Lead Critical Refinery Concern
- Strict Limit Enforced
Zn >0.5%
Full rejection or reclassification
Brass contamination indicates mixed metal scrap
Any visible solder
FULL REJECTION
- Solder Removes Bare Bright Classification
- Wire Becomes #2 Copper
Any visible coating >trace amount
FULL REJECTION
Coated wire loses bare bright premium
Steel tags, fasteners, or ferrous contamination
- Rejection Unless Removed
- Credit If Removable
- Ferrous Contamination Unacceptable
- Must Be Cleaned
Brass, aluminum, or other non-copper alloys >1%
Full rejection
- Grade Specification Violation
- Contamination
Any detectable
- Immediate Rejection
- Radioactive Waste Protocol
Any visible
- Full Rejection
- Hazardous Waste Protocol
Any detectable
- Full Rejection
- Hazmat Disposal
