Scrap yards make money by buying discarded metal at a steep discount to its market value, processing it into a form that mills and refineries will accept, and reselling it in bulk at prices much closer to the global spot rate. The gap between the buy price and the sell price is the entire business. Everything a yard does with the metal in between—sorting, stripping, baling, shredding—exists to widen that gap or to protect it from shrinking.
The Buy-Sell Spread Is the Business
Yards track daily prices on the London Metal Exchange and domestic commodity indexes, then offer walk-in sellers a fraction of those rates. Most facilities pay somewhere between 40% and 60% of current market value for metal brought in by individuals. The exact percentage depends on the metal type, the volume, and how much work the yard will need to do before resale. If copper is trading at $5.00 per pound, a yard might offer a walk-in customer $2.50 to $3.00 per pound for clean copper pipe. With copper trading above $6.00 per pound in mid-2026, even modest margins per pound turn into serious revenue at hundreds of tons a month.
That spread has to cover a long list of costs the customer never sees: labor, equipment maintenance, environmental compliance, insurance, and the constant risk that market prices drop while the metal sits in the yard. It also has to absorb processing costs, because most walk-in material arrives in a raw state no mill would accept. Commercial accounts bringing in larger, cleaner loads typically get better rates because they reduce the yard’s sorting and processing burden. The yards that last through commodity downturns are the ones that never let their buy price creep too close to their sell price, no matter how competitive the local market gets.
Sorting Is Where the Margin Is Won or Lost
The first thing that happens after metal comes over the scale is classification. Staff use industrial magnets to separate ferrous metals (iron and steel, which stick) from non-ferrous metals (copper, aluminum, brass, stainless steel, which don’t). Non-ferrous metals command dramatically higher prices per pound, so mixing the two categories is an expensive mistake in either direction.
The bigger financial threat comes from downstream buyers. A mill purchasing a load graded as clean aluminum will test it on arrival, and if they find steel fragments mixed in, they’ll either reject the shipment or reclassify it at a much lower grade. That reclassification can wipe out the entire margin the yard built into the purchase price. Experienced yards invest heavily in training employees to spot mixed loads at the gate, before the material ever hits a bin. Sorting also extends within the non-ferrous category, separating aluminum from copper and brass from bronze, because each has its own market price and purity requirements.
Processing Turns Raw Scrap Into a Commodity
Raw scrap metal has limited value. The real money appears when a yard transforms it into a standardized commodity that meets industrial specifications. Every processing step increases the per-ton price the yard can command.
Industrial balers compress loose metal (car body panels, sheet metal, appliance housings) into dense, uniform cubes. The compression alone adds value because it cuts shipping costs per ton. A truckload of loose scrap might weigh 8 tons, while the same truck packed with baled material can carry 20 or more. Freight is a major expense in this business, so the density increase goes straight to the bottom line.
Wire stripping is one of the highest-return steps a yard can perform. Insulated copper wire sells at a steep discount because the buyer has to account for the weight and disposal cost of the plastic coating. Running that wire through a stripping machine removes the insulation and upgrades the material to bare bright copper, the highest grade, which fetches premium prices. The upgrade can roughly double the per-pound price. For a yard handling thousands of pounds of wire per week, the stripping machine pays for itself fast.
Shredding operations break down complex items like cars, appliances, and mixed demolition scrap into small, uniform pieces. That standardized sizing lets mills feed the material directly into their furnaces without additional preparation, which reduces their energy costs and makes them willing to pay more per ton. Shredding also allows downstream magnetic separation and eddy current sorting to pull ferrous metal, non-ferrous metal, and non-metallic waste into separate streams.
The Highest Per-Pound Money Comes From Small Components
Bulk metal is the bread and butter, but the highest profit density comes from specialized components that contain precious metals. Smart yards pull these items before anything gets crushed or shredded.
Catalytic converters are the best-known example. Each converter contains small amounts of platinum, palladium, and rhodium, which trade at hundreds or thousands of dollars per ounce. A single converter can be worth anywhere from under $100 to over $800 depending on the vehicle type and the precious metal content at the time of sale. Yards usually don’t process these in-house. They accumulate converters and sell them in batches to specialized assay refiners who extract and pay for the precious metal content. The theft problem around catalytic converters has gotten bad enough that most states now require yards to document the source of every converter they purchase and hold them for an inspection period before resale.
Circuit boards from electronics contain gold-plated connectors, silver solder, and other recoverable metals. Lead-acid batteries are valuable for their lead content and are almost universally recycled through dedicated smelters. Both categories require careful handling (batteries contain sulfuric acid, and circuit boards may contain hazardous materials), but the per-unit value justifies the extra compliance costs. Specialized buyers pay premiums for pre-sorted, well-documented loads because the recovery from them is highly predictable.
Selling to Mills and Refineries Closes the Loop
The final revenue event happens when the yard ships its processed inventory to domestic steel mills, aluminum smelters, copper refineries, or international buyers. These are bulk transactions measured in hundreds of tons, and the prices are much closer to the global spot rate than anything a walk-in customer sees. A yard that bought copper at 50% of spot, stripped and sorted it, and sells it at 90% of spot has captured a wide margin on every pound.
These sales typically operate under contracts that specify exact tonnage, material grade, purity levels, and delivery windows. Payment usually arrives 30 to 60 days after the material is weighed and tested at the buyer’s facility. That delay creates a cash flow challenge, because yards are constantly paying out for incoming scrap while waiting weeks for revenue on outgoing shipments. Larger yards manage it with lines of credit. Smaller operations have to be disciplined about not over-purchasing during the gap.
Radiation screening catches newcomers off guard. Orphaned radioactive sources occasionally turn up in scrap loads, and mills check incoming shipments with radiation detectors. A contaminated load gets rejected and sent back at the yard’s expense. Many yards now run their own radiation monitors at the gate to catch problems before they become someone else’s problem.
Protecting the Margin From Price Swings
Scrap metal prices are volatile. A yard that buys copper at $5.00 per pound today might not sell it for two or three weeks, during which the price could drop significantly. Multiply that movement across hundreds of tons of inventory, and a bad month in the commodities market can erase an entire quarter’s profit.
Larger operations manage this risk through futures contracts on exchanges like the London Metal Exchange and the CME Group. A futures contract locks in a sale price for a specific quantity of metal at a set future date. If a yard secures a sale price through a futures contract at the same time it buys raw scrap, the margin is protected regardless of what the market does between purchase and delivery. These contracts typically cover standardized lots of 20 to 50 metric tons and require the yard to post margin as collateral, which ties up working capital but provides price certainty.
Smaller yards that can’t access futures markets protect themselves the old-fashioned way: fast turnover. They minimize the time metal sits in the yard by maintaining tight relationships with buyers and shipping frequently. Some negotiate pricing agreements where the sell price is set at the time of purchase rather than delivery, shifting the price risk to the buyer in exchange for a slightly lower rate. The yards that get burned are the ones that speculate, holding inventory because they think prices are going up, then watching the market drop.
What Eats Into the Margin
Regulation is one of the biggest hidden expenses in the scrap business, and the penalties for getting it wrong can dwarf a year’s profits.
There is no single federal scrap metal theft law. The Metal Theft Prevention Act was introduced in Congress but never enacted.1Congress.gov. S.394 – 113th Congress (2013-2014): Metal Theft Prevention Act of 2013 Virtually every state has its own scrap metal dealer statute imposing some combination of ID verification, transaction recording, holding periods, and payment restrictions. Common requirements include photographing or copying the seller’s government-issued ID, recording the seller’s vehicle license plate, documenting the type and weight of material purchased, and retaining those records for one to three years depending on the state. Many states also impose mandatory holding periods of three to ten days, during which the yard must keep purchased material on-site for law enforcement inspection before processing or reselling. Some states restrict cash payments for certain materials or above certain dollar amounts, requiring payment by check mailed to the seller’s verified address.
On the federal side, any scrap yard receiving more than $10,000 in cash from a single transaction or related transactions within 12 months must file IRS Form 8300 within 15 days.2Internal Revenue Service. Form 8300 and Reporting Cash Payments of Over $10,000 The obligation applies to the receiving side, so yards buying scrap for cash are squarely in scope. Failure to file carries penalties that are adjusted annually for inflation.3Internal Revenue Service. IRS Form 8300 Reference Guide
Environmental rules add another layer of cost. Scrap yards are classified as industrial facilities for stormwater purposes and must obtain coverage under a National Pollutant Discharge Elimination System permit.4US EPA. Stormwater Discharges from Industrial Activities That means a written stormwater pollution prevention plan, containment berms and sediment traps to prevent contaminated runoff, regular inspections, and monitoring data submissions.5US EPA. Industrial Stormwater Fact Sheet Series – Sector N: Scrap Recycling and Waste Recycling Facilities Yards that keep all operations under cover may qualify for a no-exposure exemption, but most open-air facilities don’t have that option.
Refrigerant recovery is another compliance area with sharp teeth. Any yard processing refrigerators, air conditioners, or other appliances containing refrigerant must recover that refrigerant before the unit is scrapped. Federal regulations at 40 CFR 82.156 set specific evacuation levels that must be reached using certified equipment, and only technicians holding EPA Section 608 certification can perform the work.6eCFR. 40 CFR 82.156 – Required Practices Knowingly venting refrigerant during disposal is a federal violation carrying fines that can reach tens of thousands of dollars per day per violation. Facilities must maintain records identifying each appliance, the quantity of refrigerant recovered, and where it was sent.
Lead-acid batteries fall under separate hazardous waste rules. In most states, sending them to a landfill is illegal because the lead and sulfuric acid contaminate soil and groundwater. Yards accumulating batteries for resale to lead smelters must store them upright, in acid-resistant containment, protected from weather, and document their disposition. The compliance burden is real, but so is the revenue. Lead-acid batteries are one of the most consistently recyclable products in the waste stream, and smelters pay reliable prices for them.
Stormwater permits, certified technicians, hazardous waste storage, record-keeping systems, and the occasional consultant fee all come out of the same margin the buy-sell spread creates. Yards that treat compliance as a cost of doing business from day one tend to survive. The ones that cut corners eventually face enforcement actions that cost far more than the shortcuts ever saved.
