You can sell catalytic converters containing platinum, palladium, and rhodium to specialized recycling companies, scrap metal dealers, and mail-in precious metal buyers. The most common route for individuals is either a local scrap yard that handles converters or a nationwide mail-in recycling program that processes the converter and pays you based on its assayed metal content. Where you sell matters, because payouts vary significantly depending on the buyer’s proximity to the actual refining process.
Types of Buyers and What They Pay
There are three main categories of buyers, and each sits at a different point in the supply chain. The closer your buyer is to the refinery, the more you typically receive.
- Local scrap metal yards: The most accessible option. Most cities have scrap dealers who accept catalytic converters along with other metals. They’re convenient but generally offer the lowest prices because they’re middlemen who resell to larger processors.
- Specialized converter recyclers: Companies like Legend Smelting and Recycling or RRCats focus specifically on catalytic converters. These businesses process converters in bulk, extract the ceramic honeycomb material, and either refine it themselves or send it directly to a refinery. Because they cut out intermediaries, they tend to pay more than a general scrap yard.
- Mail-in recycling programs: Several nationwide buyers accept converters shipped from anywhere in the country. RRCats, for example, operates a mail-in program with free shipping, price locks lasting 10 days, and payment by check or PayPal. Turnaround can be as fast as two days from receipt to payment. This is often the best option if you don’t have a specialized buyer nearby.
Avoid selling to individuals through classified ads or social media. The catalytic converter theft epidemic has made informal sales legally risky, and you’ll almost certainly get less than a recycler would pay.
How to Find Your Converter’s Value
Not all catalytic converters are worth the same amount. The value depends on the type and quantity of precious metals inside, which varies by vehicle make, model, and year. A converter from a full-size truck might contain $100 worth of material, while certain hybrid vehicle converters can hold several hundred dollars’ worth.
Every converter has a serial number stamped on the metal housing, usually near the center or along the edge of the case. You may need to clean off rust and grime to read it. Once you have the number, online databases like AutoCatalystMarket let you enter the serial number to see the manufacturer, model type, estimated precious metal content, and current price. Some of these tools also show buyers in your area.
Getting a quote before you sell is important. Most specialized recyclers will give you a price estimate based on photos or serial numbers before you commit. Compare quotes from at least two or three buyers.
OEM Converters Are Worth Far More Than Aftermarket
If your converter is the original equipment that came with the vehicle from the factory (OEM), it contains substantially more platinum, palladium, and rhodium than a cheap aftermarket replacement. Aftermarket converters use minimal precious metals to keep costs down, which means their scrap value is a fraction of what an OEM unit brings. Some recyclers won’t even accept certain aftermarket converters because the metal content doesn’t justify processing costs.
Before selling, check whether your converter is OEM or aftermarket. OEM units typically have the automaker’s branding or part numbers. Aftermarket converters often look simpler, with generic stamping or no branding at all. If you replaced your converter with a budget part at some point, expect a significantly lower offer.
Why Precious Metal Prices Matter
The three metals inside catalytic converters, platinum, palladium, and rhodium, fluctuate daily on commodity markets. Rhodium is by far the most volatile and most valuable of the three. Recent spot prices put rhodium around $11,250 per ounce, which is why converters with higher rhodium content command premium prices. Platinum and palladium trade at lower levels but still contribute meaningfully to a converter’s total value.
Recyclers adjust their payouts based on these spot prices, sometimes daily. If you’re not in a rush, watching price trends on a site like Kitco can help you time your sale. The 10-day price lock offered by some mail-in buyers gives you a short window of price certainty while your shipment is in transit.
Legal Requirements for Selling
Catalytic converter theft has driven a wave of state legislation tightening the rules around selling detached converters. Requirements vary by state, but the trend is clear: you need to prove you own the converter legally.
New Jersey’s law is a good example of what many states now require. Scrap metal businesses there must verify your identity with a government-issued photo ID and keep a copy on file for at least five years. If you’re selling a converter that isn’t attached to a vehicle, and you’re not a registered auto parts business, you need to provide the vehicle identification number (VIN) of the car it came from, plus a copy of the title, registration, repair receipt, or bill of sale for that vehicle. The buyer must record your name, address, and signature.
Many other states have adopted similar frameworks. Some require a waiting period before payment, and a few mandate that payment be made by check rather than cash to create a paper trail. Before you sell, look up your state’s specific requirements. If you can’t provide proof of ownership, a legitimate buyer will turn you away.
Getting the Best Price
The single biggest factor in what you’re paid is who you sell to. A general scrap yard might offer a flat rate based on a quick visual inspection, while a specialized recycler will assess the converter by serial number, weigh the ceramic substrate, or even assay the actual metal content before quoting a price. That precision almost always works in your favor if you have a high-value converter.
If you have multiple converters, perhaps from a shop or a parts collection, your leverage increases. Bulk sellers can often negotiate better per-unit pricing. Some recyclers offer tiered rates or dedicated account managers for repeat sellers. For a single converter from a personal vehicle, a mail-in recycler with transparent pricing and a price-lock guarantee is usually the most straightforward path to a fair payout.
