Utah Catalytic Converter Laws
Selling Catalytic Converters in Utah

If you’re in Utah and looking to sell a used catalytic converter, it’s crucial to understand the state’s legal framework. Utah has taken significant steps to regulate catalytic converter transactions in order to curb theft — but legal sales are still fully possible when you follow the rules.

What the Utah Law Says
Under the “HB 38 Amendments” (2022) and Utah Code Title 13, Chapter 32a, key legal requirements include:
- Buyers of detached catalytic converters must be registered and must upload detailed transaction data into a central database.
- Transactions must include verified seller ID, seller’s address, a photo or video of the converter, description of the converter (brand, serial number, weight, marks), and any vehicle information if available.
- The law presumes a detached catalytic converter may be stolen property if it lacks proper documentation or identifying marks.

✅ Yes! If you legally own the catalytic converter and can provide documentation or proof of ownership, you can lawfully sell it in Utah.
