Requires serial numbers to be engraved or stamped on all catalytic converters sold in New York state

This bill requires all new catalytic converters sold in New York State (manufactured or assembled on or after January 1, 2026) to have a permanently marked, unique serial number. The serial number must be engraved or stamped in bold, legible text at least 1/8 inch tall, visible without removal, and impossible to remove without damaging the converter. It directly affects manufacturers, assemblers, and sellers of catalytic converters within the state. The policy change aims to create a traceable identifier for these parts, which are frequently targeted in thefts.
