North Dakota Catalytic Converter Laws

Selling Catalytic Converters in North Dakota

If you’re in North Dakota and looking to sell a catalytic converter, it’s important to understand the state’s legal framework. While the state doesn’t have as many strict requirements as others, there are still regulations in place that aim to deter catalytic converter theft.

What the North Dakota Law Says

North Dakota’s catalytic converter laws are outlined in North Dakota Senate Bill 2299.

Key points:

  • It is unlawful to buy, sell, or possess a detached catalytic converter unless you’re:
    • A licensed automotive dismantler or recycler
    • A repair business or parts dealer
    • A person providing proof of ownership
  • Buyers must:
    • Record seller ID and contact info
    • Document the serial number and description of the catalytic converter
    • Keep transaction records for at least two years
    • Pay by check or traceable method (no cash sales)
  • Violations may be charged as a Class A misdemeanor or higher if theft is involved.

Can You Still Sell Your Converter?

✅ Yes! As long as you legally own the catalytic converter and can provide documentation, you’re allowed to sell it — even under North Dakota’s regulations.

We make it easy for private sellers, mechanics, and small businesses to get value from their converters legally and safely.
