Quick answer: A stolen catalytic converter is valued for its platinum-group metal content. Legitimate scrap yards pay by make and model code, typically 50 to 250 dollars per converter, up to about 800 dollars for high-loading hybrids. Replacement often costs the victim 1,000 to 3,500 dollars or more.
Short on time? The facts that matter
- National Insurance Crime Bureau reports rose from 1,298 converter thefts in 2018 to 14,433 in 2020, then insurance claims tracked by NICB grew from 16,660 in 2020 to 64,701 in 2022.
- Carfax estimated about 153,000 catalytic converters stolen in the United States during 2022, with victim losses over 382 million dollars.
- The wave was driven by a rise in palladium and rhodium spot prices between 2019 and 2022, with rhodium averaging 20,254 dollars per troy ounce in 2021 per USGS.
- Recyclers typically pay 50 to 250 dollars per converter, and up to about 800 dollars for a hybrid converter with higher loading, per a 2023 NICB report.
- The Preventing Auto Recycling Thefts Act (PART Act), S. 154 in the 118th Congress, proposes traceable identification numbers on new converters and federal criminal penalties for theft.
- Many states passed marking, registration and paper-trail laws; California AB 1740 (2021 to 2022 session) tightened core-recycler records and title checks.
- Federal law under section 203 of the Clean Air Act, at 42 U.S.C. section 7522(a)(3), makes it unlawful to remove or render inoperative a factory catalytic converter.
A catalytic converter is a small, expensive box bolted into a vehicle's exhaust. It contains a few grams of platinum-group metals, spread over a ceramic honeycomb. The metal content is small in mass but valuable enough that a wave of thefts, then a wave of state and federal laws, followed the rise in palladium and rhodium prices between 2019 and 2022. This page explains the numbers behind that wave, all cited to primary sources.
The economics that drove the theft wave
A stolen converter is worth two very different things to two very different people. To the victim, the loss is the cost of replacement plus lost use of the vehicle. To the thief, the value is what a scrap yard will pay for a used converter, minus the time and risk of cutting it off.
The gap between those two numbers is why the theft market exists. A converter that costs the owner over 1,000 dollars to replace changes hands at a scrap yard for a small fraction of that figure. The remainder pays for the risk premium, the middlemen and the refiner margin further down the chain.
The National Insurance Crime Bureau tracked reported thefts rising from 1,298 in 2018 to 14,433 in 2020. Insurance claims later tracked by NICB grew from 16,660 in 2020 to 64,701 in 2022. Independent Carfax estimates put actual 2022 thefts near 153,000 units, with victim losses over 382 million dollars.
Peer-reviewed research on the same period estimated a price elasticity of about 1.98 for converter theft. That means a 10 percent rise in platinum-group metal prices was associated with roughly a 20 percent rise in thefts. The theft curve tracks the metal curve tightly.
How PGM spot prices moved from 2018 to 2024
The theft wave lines up cleanly with what the platinum-group metals were doing on the spot market. USGS reports annual average prices in its Mineral Commodity Summaries, and the shape of the moves after 2019 is what drove the recycling channel.
Palladium averaged 1,036 dollars per troy ounce in 2018. It rose to about 1,500 dollars in 2019, 2,205 dollars in 2020, and 2,419 dollars in 2021, then held around 2,134 dollars in 2022 before falling back to 1,352 dollars in 2023 and 980 dollars in 2024.
Rhodium was even more extreme. USGS annual average rhodium prices ran 2,225 dollars in 2018, then 3,300 dollars in 2019, 11,205 dollars in 2020 and a peak of 20,254 dollars per troy ounce in 2021. Prices then fell to 15,585 dollars in 2022, 6,661 dollars in 2023 and 4,600 dollars in 2024.
Platinum, by contrast, was quieter: 883 dollars in 2018, 850 dollars in 2019, 886 dollars in 2020, 1,094 dollars in 2021, 967 dollars in 2022, 973 dollars in 2023 and 950 dollars in 2024. That relative-price story is what made the palladium-heavy gasoline converters more attractive targets than diesel units.
What a scrap yard actually pays per converter
The scrap channel does not pay a flat rate. A licensed core recycler pays by make and model, because different converter codes carry very different platinum-group metal loadings. The recycler either references a public code list, uses a proprietary buyer database, or ships to a downstream aggregator that assays each unit.
The National Insurance Crime Bureau reported in 2023 that metal recyclers typically pay between 50 and 250 dollars for a catalytic converter, and up to about 800 dollars for a converter removed from a hybrid vehicle. A small number of specific converter codes, such as older Toyota Prius and some heavy-duty light-truck codes, can trade well above that upper bound based on assayed metal content.
These are yard-payment ranges, not melt-content ranges. Melt content at spot is much higher on a light-duty gasoline converter, but the recycler has to deduct expected recovery yield, refiner margin, transportation to a specialized refiner, assay work and a settlement lag that runs weeks or months. The gap between calculated melt value and actual payment is where the recycling business lives.
| Converter class | Typical yard payment (USD) | Why |
|---|---|---|
| Standard light-duty gasoline | 50 to 250 | Modest palladium and rhodium content, priced off recent PGM spot minus recovery costs. |
| Hybrid gasoline (higher loading) | up to about 800 | Higher PGM loading because the engine cycles on and off; catalyst spends more time in cold-start. |
| Diesel oxidation catalyst (light-duty) | varies widely | Higher platinum content but softer platinum price; some codes trade above the gasoline range. |
| Heavy-duty diesel (large truck) | meaningfully more per unit | Much larger catalyst volume; PGM mass scales with exhaust flow rate. |
| Aftermarket or gutted shell | near zero | Very little precious metal content; often refused entirely by licensed recyclers. |
Ranges compiled from the National Insurance Crime Bureau 2023 report and general industry recycling references. Individual codes vary. Checked August 2026.
Which vehicles get targeted and why
Thieves do not pick vehicles at random. The pattern reported by law enforcement and by NICB is clean: high ground clearance for easy access, bolt-on converters that a pipe cutter can drop in under a minute, and known-high-loading models like older hybrids.
Late-model pickup trucks and truck-based SUVs are frequently reported targets because a person can slide under without a jack. The Toyota Prius family, particularly older generations, is over-represented because hybrid converters carry higher platinum-group metal loading than a comparable conventional gasoline vehicle. Some pickup families, including older Ford F-Series, also carry codes with above-average payouts.
Thieves typically work with a pipe cutter or a portable reciprocating saw, taking under a minute per vehicle in a quiet parking lot. That is why the theft wave was concentrated in dense parking areas: airport lots, apartment complexes, dealer lots and municipal fleets.
Where stolen and legitimate converters both end up
Both stolen and legitimate converters flow through similar downstream infrastructure. Aggregators buy from yards, then sell to specialized refiners that assay and separate the platinum-group metals. Only a small number of refiners in the world can economically recover PGMs from spent automotive catalysts.
The 2020 to 2022 federal investigation known as Operation Heavy Metal made the flow public. Stolen converters from regional theft rings were shipped to DG Auto Parts in Freehold, New Jersey. That aggregator removed the honeycomb, ground it to dust and sold the powder to Dowa Metals and Mining America for refining. Dowa then shipped the material to Japan for final separation.
The Department of Justice described the November 2022 takedown as the first national action against a converter theft ring. Simultaneous search warrants ran across 32 sites in five states, with 21 arrests, per US Immigration and Customs Enforcement. Aggregate revenue at the New Jersey aggregator was estimated near 545 million dollars over the theft-ring window.
Legitimate scrap converters follow the same physical path: yard, aggregator, specialized refiner. The difference is a paper trail. A licensed recycler collects a title copy or a written agreement, logs the vehicle year, make and model, and can trace each unit back to a documented seller. A stolen converter fails at that documentation step, which is the point of the state laws below.
Worked example: melt content at illustrative spot
The worked example below shows the metal-content math for a mid-range light-duty gasoline converter. It uses an illustrative 5-gram total loading, split as a modern gasoline mix, and USGS-reported 2024 annual average spot prices as inputs. All numbers are illustrative.
Assume a 5-gram total platinum-group metal loading in a modern gasoline converter, split as 3 grams palladium, 1.5 grams platinum and 0.5 grams rhodium (illustrative, not a spec sheet for any specific vehicle). Use the 2024 USGS annual average prices: palladium 980 dollars, platinum 950 dollars and rhodium 4,600 dollars, all per troy ounce. One troy ounce is 31.1035 grams.
- 3 grams of palladium is 3 divided by 31.1035, or about 0.0965 troy ounces. At 980 dollars per troy ounce, that content is worth about 94.53 dollars.
- 1.5 grams of platinum is about 0.0482 troy ounces. At 950 dollars per troy ounce, that content is worth about 45.79 dollars.
- 0.5 grams of rhodium is about 0.0161 troy ounces. At 4,600 dollars per troy ounce, that content is worth about 74.06 dollars.
- Add the three: about 214.38 dollars in metal content at 2024 annual average spot.
The yard payment would be a fraction of that figure. Assume the yard pays 100 dollars for the same unit. That is roughly 47 percent of the calculated melt content. Recovery yield, refiner margin, transport, assay work and settlement lag account for the remainder. At 2021 peak rhodium of 20,254 dollars per troy ounce, the same content math produces about 391 dollars in metal value, and the yard payment rises with it.
The federal response: the PART Act
Federal legislators responded to the 2020 to 2022 theft wave with the Preventing Auto Recycling Thefts Act. The bill was introduced as S. 154 in the 118th Congress (2023 to 2024) with bipartisan Senate sponsorship. Its stated goals are to add traceable identification numbers on new-vehicle converters and to make catalytic converter theft a federal criminal offense.
The core mechanism is a marked or stamped identifier on each new converter, tied to the vehicle identification number. A downstream recycler could then verify that a unit was not stolen before payment. The bill would also authorize federal grants for state marking programs and give federal prosecutors jurisdiction over interstate converter theft cases.
The PART Act had not been enacted at the close of the 118th Congress. Versions of the bill have been reintroduced across Congresses since 2022. Federal law today therefore still relies on the Clean Air Act tampering provisions and on state law for the actual theft, marking, registration and paper-trail obligations that follow.
State marking, registration and paper-trail laws
Many states enacted their own catalytic converter laws between 2021 and 2023. The common elements: mark converters at the vehicle level, tighten what a scrap yard has to record on each purchase, and limit who is allowed to sell a loose converter. Enforcement and specifics vary widely by state.
California AB 1740, chaptered as Chapter 513 of the 2021 to 2022 session and signed on September 25, 2022, is one example. The law amended the Business and Professions Code section 21610 to require core recyclers to log the year, make and model of the source vehicle, plus a copy of the vehicle title. The law also prohibits core recyclers from buying a converter from anyone other than a commercial enterprise or a documented owner of the source vehicle.
Other states have used a similar toolkit: mandatory identifying marks, delayed payment periods, cash-payment bans, seller identification requirements and licensing for used-catalytic-converter buyers. The National Conference of State Legislatures maintains a tracker of enacted and pending state legislation on this topic.
- Do not drive the vehicle further. A missing catalytic converter is loud and, in most states, is not a legal on-road condition even for a short trip.
- File a police report at the local jurisdiction where the theft occurred. Get the incident number in writing. That number is what your insurer, your body shop and any state marking database will ask for later.
- Photograph the underside of the vehicle before it is moved. A clean shear or torch-cut on the exhaust pipe is a fingerprint that helps investigators and insurers rule out other causes.
- Call your auto insurance carrier. Under most other-than-collision auto coverage, catalytic converter theft is a covered loss subject to the deductible. Other-than-collision coverage is not the same as collision coverage; verify with your carrier.
- Get a written repair estimate from a licensed shop. Replacement of a stolen converter often runs 1,000 to 3,500 dollars or more, depending on vehicle model, according to the National Insurance Crime Bureau 2023 report.
- Ask about a mechanical shield or a marked replacement unit. Some jurisdictions run subsidized marking programs; some fleets install cages, brackets or spot-welded straps as a physical deterrent.
- Keep every document: police report number, insurer claim number, shop estimate and receipts. Those are what settle the claim and, if the ring is later broken up, what identifies you as a victim eligible for restitution.
If your converter was stolen: what to do
The seven-step list above walks the practical response. The first hours matter most because the physical evidence at the vehicle, and the exact time window of the theft, are what shape both the insurance claim and any restitution later.
Other-than-collision auto coverage, sometimes called physical-damage or "other-than-collision" in policy language, is what covers converter theft. Liability-only coverage does not. If the vehicle is older and carries liability only, the out-of-pocket cost falls on the owner unless a state victim-restitution fund applies or a broken theft ring produces a court order.
Marking programs matter for downstream recovery. A converter with a serial number, a paint mark or an etched vehicle identification number is harder for a licensed recycler to accept from an unknown seller. That paper trail is what closes the loop between the theft, the yard purchase and the eventual arrest or restitution.
Why buying or selling loose converters is regulated
A loose catalytic converter is not a normal used auto part. Federal and state rules together treat it as a controlled scrap item with a documentation obligation on both sides of the transaction. That treatment reflects the fact that a very high share of loose converters in the market moved through theft channels during 2020 to 2022.
At the federal level, section 203(a)(3) of the Clean Air Act, codified at 42 U.S.C. section 7522(a)(3), makes it unlawful to remove or render inoperative a catalytic converter installed to meet EPA rules on a motor vehicle. It is separately unlawful to manufacture, sell or install a part designed to defeat that device.
At the state level, licensed core recyclers must record specific information on each purchase and, in many jurisdictions, cannot buy from anyone other than a commercial enterprise or the documented owner of the source vehicle. Cash-payment bans, delayed-payment windows and seller identification checks are common. Selling a converter that you cannot document a legal path for exposes both the seller and the buyer to criminal liability.
None of that stops legitimate replacement or professional recycling. A licensed muffler shop replacing a certified aftermarket converter under an exhaust repair is a legal transaction. A yard buying end-of-life converters from a licensed dismantler with title paperwork is a legal transaction. The rules bite when the paper trail is missing.
Limits and caveats of these figures
Several honest caveats sit around the numbers on this page.
- Theft counts differ by source. NICB tracks reported thefts and insurance claims, which understate the true total. Carfax estimates from service records point to a materially higher figure. Both are useful signals; neither is a census.
- Yard payments are ranges, not fixed prices. A given converter code can trade above or below the ranges shown here depending on the recent PGM spot price, the recycler's buyer, and local competition.
- Melt-content dollar figures in the worked example use illustrative loadings and a labeled 2024 spot price. They are not current prices, not predictions, and not a valuation of any real converter.
- State laws change. The California example above is current as of the 2021 to 2022 session. Other states pass or amend converter laws almost every legislative cycle. Check the current text of the relevant state code before relying on any specific provision.
- This page describes the theft and recycling market. It is not investment advice on the platinum-group metals and it is not a how-to for extracting metal from converters, which is separately regulated.
If a specific loading, price or state provision matters for your case, verify it directly against the underlying statute or the current USGS release. This page cites those primary sources rather than paraphrasing them.
Questions, answered
How much is a stolen catalytic converter actually worth to a scrap yard?
Legitimate scrap yards typically pay between 50 and 250 dollars for a standard light-duty converter and up to about 800 dollars for a high-loading hybrid converter, per a 2023 National Insurance Crime Bureau report. Specific code payouts move with recent platinum-group metal spot prices and vary by buyer.
Why did catalytic converter theft rise so sharply between 2019 and 2022?
The rise tracked a large move in palladium and rhodium spot prices. USGS annual average rhodium prices went from 2,225 dollars per troy ounce in 2018 to a peak of 20,254 dollars per troy ounce in 2021. Palladium doubled from 2018 to 2020. NICB-reported thefts grew from 1,298 in 2018 to 14,433 in 2020.
Which vehicles are most often targeted?
Late-model pickup trucks and truck-based SUVs, because their ground clearance makes access easy, and older hybrids like the Toyota Prius, because hybrid converters carry higher platinum-group metal loading. Some older Ford F-Series and similar pickup codes also trade above the standard payment range.
What is the PART Act and did it become law?
The Preventing Auto Recycling Thefts Act was introduced as S. 154 in the 118th Congress with bipartisan Senate sponsorship. It would require traceable identification numbers on new converters and make theft a federal criminal offense. It had not been enacted at the close of the 118th Congress; reintroduced versions have followed.
Is it legal to sell a loose catalytic converter that I own?
In most states you can only sell a loose converter to a licensed core recycler and only if you can document ownership of the source vehicle. The recycler must log the year, make and model, and often a title copy. Selling loose converters outside that channel exposes both parties to criminal liability.
Does auto insurance cover catalytic converter theft?
Other-than-collision auto coverage generally covers catalytic converter theft, subject to the deductible. Liability-only coverage does not. NICB reports that replacement often runs 1,000 to 3,500 dollars or more, so the deductible frequently absorbs a large share of the loss on older vehicles.
Can I extract the metal from a catalytic converter myself?
No. Recovery of platinum-group metals from spent converters is done at a small number of specialized refiners that operate under environmental permits. Home extraction attempts release toxic byproducts and are illegal in most jurisdictions. The market moves through licensed recyclers, not individuals.
Is the metal from a converter something I can hold in an IRA?
No. Scrap platinum-group metals from a converter do not meet the fineness or approved-product rules for a self-directed retirement account. Physical platinum held inside a retirement account is a different topic, with its own product-form rules, covered in our platinum IRA explained guide.
