New Jersey Statutes Title 39. Motor Vehicles and Traffic Regulation 39 § 10B-2

a. All major motor vehicle component parts which do not contain a manufacturer's part number shall be identified by a person who deals in used motor vehicles, motor vehicle salvage or the component parts of motor vehicles. The identification shall be made in a manner to be determined by the director when the component part is removed from a motor vehicle.

b. A person who deals in used motor vehicles, motor vehicle salvage or the component parts of motor vehicles who purchases major motor vehicle component parts out of state shall identify the parts in the manner to be determined by the director.

c. A person authorized under this section to identify motor vehicle component parts shall maintain a record of all motor vehicles and component parts which come into that person's possession together with a record of the disposition of the motor vehicles or the component parts. The records shall be maintained in a manner and form prescribed by the director and shall include proof of ownership for the motor vehicles or the component parts in that person's possession.

The director may, by regulation, exempt motor vehicles or component parts from all or a portion of the record keeping requirements based upon the age of the motor vehicles or the component parts if the director finds that the record keeping serves no useful purpose.

Upon the request of an agent of the director or a law enforcement officer, a person shall produce the records and permit the agent or officer to examine them and the motor vehicle or component parts on the premises during business hours. For a failure to produce the records or to permit their inspection as required by this section, a person shall be subject to a fine of not less than $25.00 nor more than $100.00 or imprisonment for not more than 90 days, or both. In addition, an agent of the director or a law enforcement officer may seize or take possession of the motor vehicles or component parts and hold and dispose of them in accordance with the rules and regulations adopted by the director.
