How to Sell Copper Scrap in Bulk: Grades, LME Pricing & Best Rates

You get the best price for copper scrap by selling graded, separated material in volume to a buyer who prices transparently off the LME and settles fairly on certified weight. Mixed, unsorted scrap always sells for less. This guide walks a seller — from a contractor with a truckload to a yard shipping containers — through grading, pricing, weighing, and payment so you know you're getting a fair deal.

1. Separate and grade before you sell

The single biggest lever on your payout is sorting. Copper is bought by internationally recognised ISRI grades, and clean, separated material commands a far smaller discount to the market than a mixed load. At minimum, split your copper into:

• Bare bright / mill berry (ISRI Barley) — clean, uncoated No.1 copper wire, 99.9%+. The highest-paying grade.
• No.2 copper (ISRI Birch/Cliff) — tarnished, painted, or soldered copper, and thinner or coated wire. A wider discount applies.
• Insulated copper cable — copper still in its jacket; priced on recoverable copper content, not gross weight.
• Copper pipe and tube — clean plumbing copper, usually graded with No.1/No.2.
• Brass, aluminium, and electric motors — separate non-ferrous streams that each carry their own price.

Even a rough split into bright wire, tarnished copper, and insulated cable will lift your blended rate. For exactly where each grade sits, see our copper grades guide and the Mill Berry vs Birch/Cliff comparison.

2. Understand how your price is calculated

A serious buyer prices against the London Metal Exchange (LME) copper price, not a made-up flat number. Your payout works out roughly as:

LME copper price × grade factor × verified weight

The grade factor is the discount to the benchmark: mill berry earns the smallest discount because it needs almost no processing; No.2 and insulated grades earn wider ones because more copper is lost in recovery. Because the LME moves daily, a quote is a snapshot — ask what day's price it is based on. At Atlas Copper, buy rates track the LME daily with a transparent processing margin, and volume tiers improve the rate on larger loads. To see how the benchmark, margin, and tiers combine, read how copper pricing works.

3. Get weight verified fairly

Weight should be taken on a certified scale, and you're entitled to a copy of the weigh ticket. For container-scale loads, an independent inspection (SGS, Bureau Veritas, Cotecna) protects both sides and removes any dispute over grade or tonnage. Watch for the classic trap: a high grade quoted over the phone, then a quiet down-grade at the scale.

4. Volume changes your rate

The more you consolidate, the better your price. A buyer who exports directly — shipping full container loads to overseas refiners and rod mills — sits closer to the end user than a local yard, and can pass more of the value back to you. If you generate copper regularly, ask about a standing purchase arrangement rather than selling load by load.

5. Getting paid

Agree terms in writing before the load moves: the price basis (LME reference plus the discount), grade definitions, weighing method, and settlement timing. For established sellers, payment is prompt and traceable against a verified weigh ticket. For large or recurring loads, put the arrangement on paper so every settlement follows the same rules.

6. How to spot a trustworthy copper buyer

1. They price transparently off the LME and will show you the math.
2. They grade to published ISRI standards, not vague in-house terms.
3. They have real trading history, a fixed facility, and references.
4. They weigh on certified scales and hand you a ticket.
5. They pay promptly and in a traceable way.
