Can You Sell a Catalytic Converter to a Junkyard? Rules, Prices & How-To

Yes, you can sell a catalytic converter to a licensed junkyard, scrap dealer, or specialized catalytic converter recycler. But it is not as simple as walking in with a loose converter and walking out with cash. Since 2020, over 30 states have passed laws requiring sellers to prove ownership of the vehicle the converter came from. You will need a photo ID, the vehicle title or registration, and sometimes a signed affidavit.

This guide covers who buys converters, what they pay, the legal documentation you need in every state, and how to tell a legitimate buyer from a lowball operation.

Three types of buyers (and which pays the most)

Not all converter buyers are created equal. Where you sell determines how much you pocket:

Buyer Type	Typical Payout	How They Price	Best For
General junkyard / scrap yard	$50 – $250	Flat rate based on converter size and vehicle type	Convenience, selling attached to a junk car
Specialized cat recycler	$100 – $1,500	XRF assay of actual precious metal content	Maximum payout, high-value converters
Online mail-in buyer	$75 – $1,000	Serial number lookup against price database	No local buyers, bulk sellers

What documentation do you need?

The exact requirements vary by state, but here is the baseline that most licensed buyers now require:

State-by-state rules at a glance

State	ID Required?	Title/Reg Required?	Waiting Period	Cash Allowed?
California	Yes	Yes + dismantler license	None	No (check only)
Texas	Yes	Yes	14 days	No (check only)
Florida	Yes	Yes + VIN	5 days	No (check only)
New York	Yes	Yes	10 days	No
Illinois	Yes	Yes	7 days	No
Ohio	Yes	Yes	None	Yes (under $100)
Georgia	Yes	Yes	3 days	No
Arizona	Yes	Recommended	None	Yes

This table covers the major states, but laws are changing fast. If your state is not listed, call your local salvage yard and ask what documentation they require. A legitimate buyer will always tell you upfront.

Selling attached vs. selling loose

You have two options, and the math works differently for each:

• Attached to the car (recommended): Sell the entire vehicle to a junk car buyer. The converter value gets rolled into your total offer. One transaction, one tow, one check. Most people net more this way because the car retains full value.
• Sold separately: You might get a higher price for the converter alone from a specialized recycler, but the remaining car loses $200–$500 in value without it. Do the math before cutting it off. See our catalytic converter scrap value guide for current pricing.

How to get the best price

1. Find the serial number. Look at the metal shell for a stamped code (usually 5-8 digits). This identifies the converter model and gives buyers a precise value.
2. Get 3+ quotes. Call at least one general scrap yard, one specialized recycler, and one online buyer. Prices vary by $100-$400 for the same converter.
3. Ask if they use XRF assay. Buyers who measure the actual metal content pay more than flat-rate buyers. If they "eyeball" your converter, they are guessing low.
4. Sell OEM, not aftermarket. Factory-original converters contain substantially more precious metals than cheap aftermarket replacements. If your cat is aftermarket, expect $10–$30.

Red flags: how to spot a bad buyer

• Pays cash with no documentation: Legitimate recyclers are required by law to keep records. Cash-only, no-ID buyers are either unlicensed or dealing in stolen goods.
• No fixed business address: Mobile "cat buyers" who meet you in parking lots are often unlicensed. Deal with established businesses that have a physical location.
• Quotes a price without seeing the converter: Anyone who offers a firm price over the phone without knowing the serial number is guessing — usually low.
• Pressure to sell immediately: A reputable buyer will give you time to compare offers. If they pressure you to "sell now before prices drop," walk away.
