Chemical Composition
Elemental breakdown by percentage weight.
Standard composition limits
Values represent maximum allowed percentage unless otherwise noted.
Physical Properties
Material form, density, and contamination specifications.
Low-value circuit boards from basic electronics; end-of-life power supplies and simple electronics; minimal precious metal content (negligible gold; 5-50g copper primary); copper-focused value recovery; extreme heterogeneity; ABSOLUTELY HIGHEST supplier count commodity (445 suppliers); volume-driven bulk commodity extreme; precious metal recovery economically irrelevant; hazmat/environmental straightforward baseline; mass disposal/recycling commodity
Acceptable Inclusions
- Gold negligible 0-0.02g (low-grade specification)
- Copper 5-50g (primary value; highly variable acceptable)
- Solder variable (lead-free modern typical)
- Nickel <1g (trace)
- Silver <0.5g (negligible)
- Epoxy-fiberglass substrate (inert; variable weight)
- Dust/contamination typical (commodity acceptable)
- Mixed board types (heterogeneous extreme)
Prohibited Materials
- Intact batteries (hazmat; separate)
- Mercury components (explicit hazmat extreme)
- Fluid leakage (liquid hazmat)
Quality Assurance
Testing protocols, sampling methods, and acceptance criteria.
Sampling Protocol
frequencySpot-check verification only; statistical composition assumed; RoHS compliance assumed modern standard
maximumQuantity5000-50,000+ boards per shipment
minimumQuantity200-1000 boards or 50-100 kg
percentage0.5-2% of lot
Acceptance Limits
all Criteria Must PassMaterial appear low-grade commodity boards; copper recovery focus; bulk commodity specification
copper BasisCopper-focused commodity assumed; precious metal recovery irrelevant
hazmat ProfileRoHS compliance modern; no obvious hazmat detected
low Grade StatusConfirmed as low-grade basic e-waste; commodity status verification
Weight Tolerance
measurementBulk weighing acceptable; precision irrelevant; statistical standardization
variance±50% from estimated weight

Acceptance Criteria
- No obvious mercury/active hazmat detected
- RoHS compliance ASSUMED standard
Procedure
- Visual spot-check (0.5-1%)
- quick mercury/active hazmat visual scan
- RoHS compliance
