Minnesota Catalytic Converter Laws

Selling Catalytic Converters in Minnesota

If you’re in Minnesota and have a catalytic converter to sell, there are a few legal points to know. Like many states, Minnesota has passed laws aimed at reducing catalytic converter theft — but legal sales are still allowed if you follow the right process.

Sell Your Converter

What the Minnesota Law Says

Minnesota law restricts who can legally sell and buy detached catalytic converters. According to Minnesota Statutes § 325E.21, only certain individuals or businesses can sell a used converter, and it must include specific identification information.

To sell a catalytic converter legally in Minnesota, you’ll need:

  • A valid photo ID
  • Proof of ownership (such as a vehicle title or repair receipt)
  • A VIN engraved on the converter or proof of a licensed seller status

Scrap metal dealers in Minnesota are also required to:

  • Record and upload all transactions to the state’s Automated Property System (APS)
  • Keep records for at least 3 years
  • Refuse transactions that involve unmarked, altered, or suspicious converters

Cash payments may sometimes be restricted or prohibited, depending on the seller’s status.

✅ Yes! If your converter is legally owned and you have the proper documentation, you can still sell it — even with Minnesota’s strict laws.
