Scrap Grading System Explained (Maximize Scrap Value & Pricing Guide 2026)
Many businesses lose money on scrap simply because they don’t understand grading. Mixing materials, selling low-grade scrap, or ignoring quality standards can reduce prices by 20–50%. Scrap buyers don’t just purchase based on weight they pay based on grade, purity, and contamination levels.
In this scrap grading system explained guide, you’ll learn how scrap is classified, grading standards for metals, real pricing differences, and how to upgrade your scrap grade to maximize profit in global markets.
What is Scrap Grading System?
The scrap grading system is a standardized method used to:
- Classify scrap based on purity and composition
- Determine market value and pricing
- Ensure consistency in buying and selling
Higher-grade scrap = higher price per kg.
Why Scrap Grading Matters
Pricing Impact
- Clean, sorted scrap gets premium rates
- Mixed scrap sells at discounted prices
Buyer Trust
- Standardized grades improve transparency
Export Quality
- International buyers require strict grading standards
- Types of Scrap Grades (Industry Standard)
Ferrous Scrap Grades (Steel & Iron)
| Grade | Description | Price Level |
|---|---|---|
| HMS 1 | Clean steel, no coatings | High |
| HMS 2 | Mixed steel with slight impurities | Medium |
| Shredded | Processed small steel pieces | High |
| Bundled | Compressed steel scrap | Medium |
HMS (Heavy Melting Scrap) is the most traded category globally.
Non-Ferrous Scrap Grades (Copper, Aluminum, Brass)
Copper Scrap Grades
- Bare Bright Copper → Highest purity (premium price)
- #1 Copper → Clean, unalloyed copper
- #2 Copper → Slight contamination
Aluminum Scrap Grades
- Extrusion Aluminum → Clean profiles
- Sheet Aluminum → Mixed sheets
- Cast Aluminum → Lower grade
Brass Scrap Grades
- Honey Brass → Clean, uncoated
- Mixed Brass → Lower grade
Non-ferrous metals have the highest price variation based on grade.
E-Waste Scrap Grades
- High-grade → Circuit boards, CPUs
- Medium-grade → Mixed electronics
- Low-grade → Plastic-heavy components
Value depends on precious metal content.
Plastic Scrap Grades
- PET (bottles) → High demand
- HDPE → Industrial use
- Mixed plastics → Low value
Scrap Grading Pricing Difference (USD & AUD)
| Material & Grade | Price (USD/kg) | Price (AUD/kg) |
|---|---|---|
| Copper (Bare Bright) | $9 – $11 | $14 – $17 |
| Copper (#2) | $6 – $8 | $9 – $13 |
| Aluminum (Clean) | $2.5 – $3.5 | $4 – $5 |
| Aluminum (Mixed) | $1.5 – $2 | $2 – $3 |
| Steel (HMS 1) | $0.5 – $0.7 | $0.8 – $1 |
| Steel (Mixed) | $0.2 – $0.4 | $0.3 – $0.6 |
Better grading can increase revenue by 30–60%.
How Scrap is Graded (Step-by-Step)
Step 1: Visual Inspection
- Check contamination
- Identify material type
Step 2: Sorting & Segregation
- Separate metals, plastics, e-waste
Step 3: Testing & Analysis
- Magnet test (ferrous vs non-ferrous)
- Chemical composition analysis
Step 4: Classification
- Assign grade based on standards
Step 5: Pricing
- Buyers assign price based on grade + market rates
