How to Recycle Catalytic Converters
Exhaust emission devices with a ceramic honeycomb coated in platinum, palladium, and rhodium. NADA notes black-market stolen converters can fetch about $20-$350 while average replacement cost for owners runs over $2,500. Legal recycling goes through licensed yards with ID and vehicle paperwork.
Quick answer
Catalytic converters are recycled for platinum, palladium, and rhodium through licensed scrap buyers. Bring proof of ownership (ID, title, or repair paperwork). Most states require scrap yards to keep detailed sales records because converters are a common theft target. Street cash payouts with no paperwork are a red flag.

- 5Store the converter locked until you reach a licensed buyer
- 6Get a written receipt that lists the metals or unit price

- Exhaust specialty shops that buy cores
Theft of converters rose with precious-metal prices. Most states now regulate converter sales. States including California, New York, Texas, Minnesota, Illinois, Oregon, and Washington require the buyer to record the seller government photo ID, the VIN the converter came from, and a description and weight of the unit. Many of those states also bar cash payment, so the buyer pays by check or traceable transfer, and require records be kept for about two years and produced to law enforcement on request. Some states add e-reporting, buyer permits, or permanent marking. Cash-only curb buyers who skip paperwork are often illegal. Never leave a removed converter in an unlocked truck bed. The federal PART Act (H.R. 5221 / S. 2238, 119th Congress) is still a bill, not enacted law.
A typical converter holds a few grams of platinum-group metals. Refiners recover those metals for new catalysts and other industrial uses so mined metal demand for replacements stays lower.

How do I know what my catalytic converter is worth?
Get quotes from licensed recyclers who price by vehicle year/make/model or assayed metal. Luxury, truck, and hybrid units often pay more than basic passenger cars. Markets move; avoid hard national dollar claims.
Why are converters stolen so often?
They hold pricey metals, sit under the vehicle, and can be cut off in minutes. Trucks and hybrids are frequent targets because of ground clearance and metal load. NADA notes replacement commonly costs owners more than $2,500 while stolen units may sell for roughly $20-$350 on the black market.
Do I need ownership proof to sell one?
Usually yes. Licensed buyers ask for photo ID and proof the converter came from your vehicle (VIN, title, or shop invoice). State laws commonly require those records.
What's inside a catalytic converter that buyers pay for?
Platinum, palladium, and rhodium on a ceramic honeycomb. Those metals catalyze exhaust reactions and trade at high prices per ounce.
Should I remove the converter myself?
Only with the right tools and a cool exhaust. Damage or cutting the substrate cuts scrap value. Many owners leave removal to the shop that is installing the replacement.
How can I reduce theft risk?
Park in lit or locked areas, use a cat shield or cage where it fits, and ask your insurer what theft coverage you have. Engraving or marking helps if police recover a unit.
What is the PART Act?
Proposed federal bills (H.R. 5221 / S. 2238 in the 119th Congress) would require traceable IDs stamped on converters, tighten buyer records, and make converter theft a distinct federal criminal offense. They are not enacted law. H.R. 5221 was forwarded by the House Commerce, Manufacturing, and Trade Subcommittee to the full Energy and Commerce Committee in February 2026, so it is moving but has not passed either chamber. Check current status before citing it as law.
Are aftermarket converters worth as much?
Often less. Many aftermarket units use less platinum-group metal than OEM. Ask the buyer before you haul.
