In over a decade of trading copper for businesses of every size, I’ve seen the same call come in weekly: a facilities manager or contractor has a bin of copper wire scrap for sale and no idea what it’s actually worth. The gap between a rough guess and an accurate grade can be 40% of the payout or more, and that gap is entirely closeable once you understand how grading works.
| How Is Copper Wire Scrap Graded?Copper wire scrap is graded by purity, coating, and copper yield. The main tiers, from highest to lowest value, are bare bright, No. 1 copper wire, No. 2 copper wire, and ICW (insulated copper wire), which is priced by the percentage of copper recovered after processing. |
Grading standards for copper wire trace back to ISRI, the Institute of Scrap Recycling Industries, whose classification codes remain the reference point most U.S. buyers, refiners, and yards use to describe material sight unseen. If you’re listing copper cable for sale or requesting a quote, using ISRI-aligned terminology gets you a faster, more accurate offer.
Copper Wire Grading Tiers
| Grade | Description | Typical Copper Content | Price Tier |
| Bare Bright | Clean, bare copper wire, no coating, insulation, or oxidation | 99%+ | Highest |
| No. 1 Copper Wire | Clean copper wire or tube, light tarnish, no insulation | ~99% | High |
| No. 2 Copper Wire | Copper wire with some tarnish, solder, or minor mixed metal | 94-96% | Medium |
| ICW (Insulated Copper Wire) | Wire with plastic or rubber insulation still attached | 20-80% (varies by yield) | Lower, priced by yield |
Bare bright commands the top price because it requires no further processing, it’s clean, uncoated wire ready for direct melt. No. 1 copper wire is nearly as valuable but may carry light tarnish. No. 2 copper wire includes minor contamination or solder joints. ICW, insulated copper wire, is the category most businesses misjudge, since its value depends entirely on the copper yield after the insulation is stripped or chopped, not the gross weight of the spool.
A mid-sized electrical contractor we work with used to sell all of its job-site offcuts as one mixed ICW lot. After we walked their team through separating bare bright pigtails from insulated romex and low-yield control wire, their per-pound return on the same monthly volume increased by roughly 35%, without generating a single pound of additional scrap. That’s the value of matching the right grade to the right buyer instead of dumping everything into one bin.
Pricing for selling copper wire also tracks the broader copper commodity market, since scrap value is typically quoted as a percentage of COMEX or LME copper benchmarks. When benchmark copper prices move, scrap copper cable for sale follows within days, which is why locking in a marketplace relationship rather than chasing the lowest quote on a single load tends to pay off for repeat sellers.
Example ScrapGo Reference Pricing
The table below reflects illustrative reference ranges based on ScrapGo marketplace activity. Actual selling copper wire price varies daily with commodity markets, regional demand, and load size, so always confirm current rates before shipping.
| Grade | Example Price Range (per lb, USD) | Yield Basis |
| Bare Bright | $3.60 – $3.90 | Direct weight |
| No. 1 Copper Wire | $3.30 – $3.60 | Direct weight |
| No. 2 Copper Wire | $2.90 – $3.20 | Direct weight |
| ICW (mixed insulation) | $0.80 – $2.00 | Priced by copper yield % |
If you’re searching for copper wire for sale near me, it’s worth comparing a local yard’s walk-in rate against an online marketplace quote before committing to a load. Local yards offer same-day payment but often price to their own resale margin, while a marketplace like ScrapGo lets you compare multiple verified buyers against the same grade, which usually surfaces a better net price on anything above a few hundred pounds.
Preparation matters as much as grading when it comes to maximizing what you’re paid. A handful of steps consistently move a load from a lower tier to a higher one:
- Separate bare bright wire from any insulated or coated wire before weighing
- Remove connectors, plugs, and non-copper hardware from cable ends
- Keep different wire gauges in separate containers when volume allows
- Avoid wetting or oiling wire, since moisture and contamination reduce yield
- Request a grade breakdown on your invoice so you can track pricing over time
Buyers evaluating a large purchase order should apply the same logic in reverse: ask for photos of representative samples, confirm whether pricing is by gross weight or copper yield, and request grade documentation before wiring payment on any sizable copper cable for sale listing.
The ScrapGo Approach
ScrapGo was built so businesses selling copper wire don’t need a trading desk to get a fair price. Every listing includes grade classification, yield estimates for ICW lots, and buyer verification, so sellers can compare offers across a wider pool than a single local yard, and buyers can source copper wire for sale with confidence in what they’re actually getting.
Grading is the single biggest lever businesses have over what a load of copper wire scrap actually pays out. Learn the tiers, prep your material accordingly, and treat pricing as a market you can compare, not a number one buyer hands you.
FAQs
Q1. How is copper wire scrap graded?
Copper wire scrap is graded mainly by purity and coating: bare bright is the cleanest and highest-value tier, followed by No. 1 and No. 2 copper wire, with insulated copper wire (ICW) priced separately based on the copper yield recovered after processing.
Q2. What’s the difference between bare bright and No. 1 copper wire?
Bare bright is completely clean, uncoated copper wire with no tarnish or insulation, while No. 1 copper wire is nearly as pure but may show light surface tarnish. Bare bright typically sells for a few cents more per pound than No. 1.
Q3. How is the selling price for copper wire determined?
Copper wire pricing is based on its grade, current copper commodity benchmarks like COMEX or LME, and, for insulated wire, the estimated copper yield after stripping. Buyers typically quote a percentage of the benchmark price adjusted for grade.
Q4. Where can I get the best price when selling copper wire?
Comparing multiple verified buyers, rather than accepting the first quote from a single local yard, generally produces a better net price, especially on loads above a few hundred pounds. Online marketplaces like ScrapGo let sellers compare offers against the same grade.
Q5. Do I need to strip insulation before selling copper wire?
Not necessarily. Insulated copper wire (ICW) can be sold as-is and is priced by estimated copper yield, but stripping or separating bare bright wire from insulated wire before sale generally increases the total payout.
