"Where to sell catalytic converter" is searched about 3,600 times a month worldwide, according to Ubersuggest, with "sell catalytic converter" about 1,900, "sell catalytic converter near me" about 1,000, "where can I sell catalytic converter near me" about 480 and "how to sell catalytic converter" about 320. Advertisers pay about 2 dollars a click for them. People searching are usually holding one or a handful of converters, from a repair or a scrapped car, and want to know who will pay and how much of a hassle it is. This guide compares the places that buy converters, explains why quotes differ, and lists what to bring. Our companion guide to how the scrap price is set covers the arithmetic, and the whole family sits under our guide to selling scrap cars, car parts and used tires online. We quote no prices, because the figures we found come from buyers' own pages and move with metal markets. ScrapTrade runs a scrap marketplace and has a commercial interest in the scrap trade.
Why the buyer matters more than for other scrap
Most scrap is paid by weight, so two yards quoting the same grade end up close. A converter is different, because its value sits in a thin coating of platinum, palladium and rhodium on a ceramic honeycomb, and weight does not show how much metal is there. Trade sources describe two ways of pricing it: a flat unit price from a catalog or serial number, and a price based on an assay of the milled ceramic. Smaller or single units are often bought at a unit price, and one equipment guide says local yards often pay less because they have no assay equipment. Both are sources with something to sell, so treat them as a reason to compare, not as a ranking.
The places that buy
- Scrap yards. The easiest to reach, and many buy across the counter. They may pass converters up the chain to a larger buyer, and take a margin for it.
- Auto recyclers and dismantlers. They remove converters from the cars they buy, so they know the types and often buy converters from repair shops as well.
- Specialist converter buyers. They deal in converters and usually grade by make, model and serial number. Many publish price lists, which are a starting point and not an offer.
- Refiners. They process converters and pay on assay, but they usually want lots, not single units. Some sell through intermediaries.
- Online buyers. Some quote from photos or serial numbers and take the converter by mail or courier. Ask who bears insurance and shipping, and what happens if the grade differs from your description.
- Trade marketplaces. For sellers with volume, as below.
We did not review marketplace or classified-site policies on converters, so check a platform's rules before listing one there.
Step by step to a clean sale
- Know where it came from. Note the vehicle, its VIN and registration, and keep the repair order or the car's papers. A legitimate buyer will ask, as Catalytic Converter Buyers: What to Check explains.
- Identify it. Photograph the stamp and the shell, as our guide to identifying a converter describes. Do not cut it open.
- Get two or more quotes. Quotes for the same converter can differ for reasons you cannot see, so a single offer tells you little.
- Ask how it is priced. By unit or by assay, which deductions apply and how long the quote is good for.
- Show your records. Photo ID, proof of ownership or the repair order, as local rules require.
- Agree payment first. Method, timing and whether it is paid before the converter leaves your hands. Some jurisdictions restrict cash or require checks for converters, which we cover in the buyers guide.
One converter or a box of them
One converter from a repair is simplest sold locally, and the quote you want is a firm one in writing. A box of them from a workshop, a wrecker's shelf or a fleet's retired vehicles is different, because a larger lot is worth the effort of assay pricing and of calling several buyers. Keep the lot sorted by type, count the units and photograph them together, because grading is the first step at any buyer.
Where ScrapTrade fits
Selling one converter to a local yard is quick, and we would not say ScrapTrade is a better way to do it. The sellers it suits are workshops, wreckers, fleets and aggregators with converters in volume. ScrapTrade is a scrap marketplace with verified traders in more than 50 countries, and precious metals and e-waste are among its twelve categories. Listing is free with no commission, price and terms are negotiated in real time, and once you accept a bid the buyer's 5 percent deposit is held in escrow. Both businesses and individuals can sell after verification. We could not confirm whether converters can be listed or how assay is handled, so ask cs@scraptrade.com.au first.
What we could not verify
- What any buyer pays. We found no reliable price source.
- How each type of buyer prices, beyond trade descriptions. The sources are buyers and equipment vendors.
- Platform and local rules in each country.
- Whether ScrapTrade lists converters, and how assay would work.
