Requires motor vehicle manufacturer to stamp motor vehicle identification number on catalytic converters.

This bill requires motor vehicle manufacturers (defined as those producing at least 10 new vehicles annually) to stamp each catalytic converter with the vehicle's unique identification number before installation. It directly affects manufacturers selling vehicles in New Jersey, mandating this marking on all catalytic converters. Violations are treated as consumer fraud under New Jersey law, subjecting offenders to fines up to $20,000 per offense and potential legal action. The law aims to improve traceability of catalytic converters, which are frequently stolen for their precious metals.
