Iowa Catalytic Converter Laws
Selling Catalytic Converters in Iowa

In Iowa, the sale and purchase of catalytic converters are subject to specific legal rules, aimed at preventing theft and unauthorized resale. If you’re looking to sell a converter and want to do so legally and smoothly, knowing these rules is vital — and working with RRCats offers a compliant and convenient path.
SELL YOUR CONVERTER
What the Law Says in Iowa
Under Iowa Code § 714.27A (2024) — “Used catalytic converter transactions — reporting — penalties” — Iowa requires both sellers and buyers of converters to follow defined steps:
- Seller Obligations:
- At or before the sale, the seller must provide their name, address, and place of business (if any) and present valid photo ID (driver’s license, passport, or other government‑issued ID).
- If the seller operates a business at a fixed location in Iowa, they must provide the purchaser either:
- A valid Iowa sales tax permit (under Chapter 423)
- Or a valid business license or permit from another state (if operating out of state)
- For non‑business sellers (i.e., individuals), acceptable proof may include an original receipt/invoice for a replacement converter purchased within 30 days, or a junking certificate for the vehicle from which the converter was removed.
- Buyer / Dealer Obligations:
- The purchaser must demand and receive the required seller information (ID, business permit, etc.) before buying a converter.
- The purchaser must mark the receipt/invoice/junking certificate (or other proof) to indicate the converter was sold, and take a photograph of the converter clearly identifying it.
- The purchaser must have a residence or fixed business address in Iowa (for buyers) when the transaction is made.
- The purchaser must keep a confidential log of each transaction containing all required information, and the records must be retained at least two years.
- Payments must use a traceable payment method — such as check, voucher, prepaid bank/credit/debit card, or electronic funds transfer. Cash payments are not acceptable.
Can You Still Sell Your Converter?
Yes — you can. But you must meet all the documentation and verification steps if the converter is being sold in Iowa. For many sellers who do not have a business license or operate outside the dealer‑framework, it may be more efficient to ship your converter out of state.
Selling to RRCats from Iowa
Since RRCats is based in New Jersey and operates under New Jersey law rather than Iowa’s dealer‑specific resale rules, you as an Iowa seller can ship your catalytic converter to us legally (assuming the item is legitimately owned and documented). This gives you major advantages:
- Avoid complex license/permit requirements for Iowa in‑state transactions
- Use a fully licensed out‑of‑state buyer with secure, traceable payment
- We handle shipment, documentation review, and payment processing to keep everything above board
- You still provide your ID and proof of ownership, but we remove you from the burden of local compliance
