Preventing Catalytic Converter Theft

Our company is dedicated to following the regulations for purchasing and recycling scrap catalytic converters as outlined in California B&P Code 21610 and Vehicle Code 10852.5. We only purchase catalytic converters from reputable sources and have internal policies in place to prevent the acquisition of stolen converters.


California law (B&P Code 21610 and Vehicle Code 10852.5) strictly enforces the requirements for purchasing detached catalytic converters. All purchasers of catalytic converters in California – without exception – must follow these requirements.


Failure to comply with these requirements may subject you to criminal prosecution, monetary fine up to $2,500 per violation, and a court order prohibiting the future purchase of catalytic converters.


Core Recyclers – Who is bound by California law?

California law applies to all “Core Recyclers”, which is defined is any person or business that buys catalytic converters detached from a vehicle. A business that does not buy detached converters, but obtains units still attached to a vehicle (e.g. auto dismantler) or during the process of a legitimate vehicle repair (e.g. muffler shop), are not Core Recyclers.

Prohibited Purchases

Core Recyclers are strictly prohibited from purchasing catalytic converters from anyone except:

  • A “Commercial Enterprise” which Includes the following:

    1. California licensed automobile dismantlers

    2. California licensed vehicle manufacturers, dealers, or lessor-retailers

    3. California licensed automotive repair dealers

    4. Core Recyclers (as defined above) that maintain a fixed, physical place of business

    5. Any other licensed businesses that may reasonably generate, possess, or sell used converters

  • A “Vehicle Owner” for the vehicle from which the converter was removed.

Written Agreement Required

Core Recyclers are required purchase catalytic converters using a “Written Agreement”, which much list each converter purchased and describe each sufficiently so that it can reasonably be matched to its description in the agreement.

Other Required Records

In addition to the Written Agreement, Core Recyclers must maintain a record of all purchases from a Commercial Enterprise or Vehicle Owner. The record must contain all information detailed below. Further, the record must be accessible to law enforcement upon request and must be retained by the Core Recycler for at least two years.
