A catalytic converter is worth selling for its platinum (Pt, 78), palladium (Pd, 46) and rhodium (Rh, 45) content, valued at roughly $250 for an average North American unit on the World Platinum Investment Council's (WPIC) 2024 price basis, not its scrap steel. Where a seller can legally take that converter, how the buyer grades it, and how the payment gets made all change what that $250 becomes in hand. The sections below cover the three tiers of buyer, how each one prices a converter, how payment works, and what US state law requires before the sale is legal.
Where Can You Sell a Catalytic Converter?#
A converter can be sold to three tiers of buyer: local scrapyards and dismantlers, core buyers and aggregators, or, for large lots only, a refiner directly. Each tier sits further from the metal price and closer to the finished, refined bar. Scrap platinum, palladium and rhodium of every kind, from converters to jewelry, moves through the same downstream chain described on scrap platinum, palladium and rhodium, and a converter is simply the highest-volume feedstock in that chain.
| Buyer tier | Who they are | Typical lot size | Access for a single seller |
|---|---|---|---|
| Scrapyard or dismantler | First-stage buyer that strips end-of-life vehicles and buys loose converters over the counter | One converter | Direct; the easiest and most common route |
| Core buyer or aggregator | Sorts, decans and assays converters bought from yards and the public, pricing many by code or database match | Tens to hundreds of units | Direct, by mail-in or local drop-off, or through a scrapyard |
| Refiner | Smelts and chemically separates the PGM from crushed, homogenized substrate | Around 1 tonne per lot | Indirect only, through an aggregator |
Local Scrap Yards and Dismantlers#
A scrapyard or dismantler is the first buyer in the chain, sorting converters by substrate type before selling them on to an aggregator. It is the most accessible option for a one-off sale, since a yard buys a single unit over the counter, though its offer is usually built on eye-graded estimates rather than a per-unit assay.
Core Buyers and Aggregators#
Core buyers and aggregators assay or database-price a converter before paying for it, whether the sale happens at a local yard or through a mail-in buyer. Catalytic converter recycling, the decanning, crushing and refining steps that turn a whole converter into refined metal, is covered in full on catalytic converter recycling, including how the aggregator's own assay feeds that process.
Why You Cannot Sell Directly to a Refiner#
A single converter cannot go straight to a refiner, because refiners set lot minimums of around 1 tonne, far more than one seller has. Ecotrade Group, a toll refiner, sets its own minimum at 500 kg, while smaller lots can be sold outright under a "Fast Settlement" service instead of refined on the seller's account. That gap between one converter's few kilograms and a tonne-scale lot is why the aggregator tier exists: it aggregates volume a refiner will accept.
How Buyers Grade a Catalytic Converter#
A buyer grades a converter on what it is, not just what it weighs: substrate type, engine type and whether it is OEM or aftermarket. Two converters of identical size and weight can carry very different PGM loadings, so identity, not bulk, sets the price.
Identification: OEM, Aftermarket, Gasoline or Diesel#
An OEM converter grades higher than an aftermarket one of the same application, commonly by 3 to 5 times, because it carries a known, higher PGM loading, according to the scrap buyer RRCats. Gasoline and diesel units also differ: a gasoline three-way catalyst carries platinum, palladium and rhodium together, while many diesel components carry platinum and palladium only. The signals that separate an aftermarket vs OEM catalytic converter are covered on aftermarket vs OEM catalytic converter.
Converter Codes and Price-List Lookups#
Many buyers price from a converter code matched against a sampled-average database, such as the open ConverterDatabase.com, rather than a live assay of that specific unit. ConverterDatabase.com describes itself as built from over 5,030 individually sampled converters, searchable free by serial number or manufacturer. Because the match is a statistical average, two converters stamped with the same code can genuinely assay differently. The manufacturer formats a buyer reads to find that code are explained on catalytic converter codes and serial numbers.
How Payment Works#
Legitimate buyers pay by check or electronic transfer, not always cash, because a growing number of states restrict or ban cash payment for scrap converters.
| Payment method | Typical status |
|---|---|
| Cash | Restricted or banned outright for a detached converter in a growing number of states |
| Check | Standard, traceable method most buyers use |
| Electronic transfer | Standard, traceable method most buyers use |
Cash, Check or Electronic Transfer#
The no-cash rule exists because an untraceable cash sale is what made converter theft liquid; a buyer asking for identification and a signature is following the law, not adding friction. Catalytic converter theft, covered on catalytic converter theft, tracked the rhodium and palladium price closely enough that removing the anonymous cash sale is lawmakers' first move.
Why the Quoted Price Moves With the PGM Market#
The quoted price moves with the platinum and palladium spot price, because those two metals, not steel, set the converter's value. In the average passenger-vehicle autocatalyst there is roughly three times as much palladium as platinum by weight, according to WPIC, so a palladium move typically changes a quote more than an equal platinum move. How a buyer turns spot metal prices into a per-unit offer is explained on catalytic converter scrap prices.
Is It Legal to Sell a Catalytic Converter? Rules by US State#
Selling a catalytic converter is legal everywhere in the US, but a growing number of states require the seller to prove who they are and where the converter came from. No state bans the sale outright; the laws instead target the anonymous, undocumented transaction that lets a stolen unit move as easily as a legitimately removed one.
Federal Law: No National Converter-Theft Statute (Yet)#
No federal catalytic-converter theft or sale statute has been enacted: the Preventing Auto Recycling Thefts (PART) Act was reintroduced in both chambers of Congress in 2025 and remains in committee. Senator Amy Klobuchar introduced S. 2238 on 10 July 2025, and Representative James Baird introduced the House companion, H.R. 5221, on 9 September 2025. As drafted, it would require vehicle identification marking on new converters and documentation of sales, but neither chamber has voted on it, and two earlier versions died in committee in prior Congresses.
Typical State Requirements#
State laws enacted between 2021 and 2024 typically require recording the seller's identity and the vehicle's VIN, paying by traceable means rather than cash, and observing a hold period, and in some states restrict sale to a licensed dismantler or the vehicle's registered owner. The National Insurance Crime Bureau tracked 163 such bills across 37 states in 2022, of which 31 were enacted, and 94 more bills across 39 states through 10 May 2023, of which 12 were enacted by that date. DailyPlatinum's sources do not support a verified, current state-by-state list, so none is published here; a seller should confirm the specific rule in their own state before selling.
| Requirement type | Typical provision |
|---|---|
| ID verification | Seller shows government-issued identification |
| Vehicle record | Buyer records the vehicle's VIN, not just the converter |
| Payment method | Payment by check or electronic transfer, not cash |
| Hold period | Buyer holds the converter for a set number of days before processing it |
| Seller eligibility | Some states limit sale of a detached converter to a licensed dismantler or the vehicle's registered owner |
Getting the Best Price#
Getting the best price means comparing more than one buyer's offer, not accepting the first quote.
Compare Offers Before You Sell#
Buyer offers can differ on grading method and lot access alone, before the metal price is even considered: a yard pricing by eye, an aggregator pricing by code match, and a buyer with refiner access can each land on a different number for the same converter. Catalytic converter buyers and recyclers are compared side by side, with the same offer, on catalytic converter buyers and recyclers; DailyPlatinum may earn a referral fee from listed buyers.

Selling FAQ#
Who pays the most for a catalytic converter?#
The buyer paying most is usually whichever tier can identify the converter's exact PGM content: an aggregator or refiner-linked buyer who grades by code typically outpays a yard pricing by eye, because it is not guessing at the metal loading behind its offer.
Do I need ID or a title to sell a catalytic converter?#
Increasingly yes: many state laws require a buyer to record the seller's ID and the vehicle's VIN before completing the purchase, even though the seller is not required to hold a title to the specific vehicle the converter came from.
Can I sell a catalytic converter for cash?#
In a growing number of states, no: cash payment for a detached converter is restricted or banned, and payment must be made by check or electronic transfer instead.
Is a catalytic converter worth more than gold?#
Not usually: the average North American converter's contained metal value was $250 in 2024 (WPIC), made up of $39 of platinum, $126 of palladium and $85 of rhodium, well below the price of a single ounce of gold. Rhodium itself, however, has traded far above gold's price per ounce, which is why it can make up more of that $250 than platinum does.
