Code of Federal Regulations Title 40. Protection of Environment § 40.85.1512 Admission of catalyst and O 2 sensor-equipped vehicles

(b) For the purpose of this section, “catalyst and O₂ sensor control program” means a program instituted and maintained by a manufacturer, or any U.S. Government Agency for the purpose of preservation, replacement, or initial installation of catalytic converters and cleaning and/or replacement of O₂ sensors and, if applicable, restricted fuel filler inlets.

(c) For the purpose of this section, “driven outside the United States, Canada and Mexico” does not include mileage accumulated on vehicles solely under the control of manufacturers of new motor vehicles or engines for the purpose of vehicle testing and adjustment, and preparation for shipment to the United States.

(d) Vehicles conditionally imported pursuant to this section and under bond must be modified in accordance with the certificate of conformity applicable at the time of manufacture. In the case of vehicles previously imported under § 85.1509 or § 85.1504 (prior to July 1, 1988), the replacement catalyst and O₂ sensor, if applicable, must be equivalent (in terms of emission reduction) to the original catalyst and O₂ sensor. Such vehicles may be granted final admission upon application to the Administrator, on forms specified by the Administrator. Such application shall contain the information required in § 85.1504(a)(1) (i) through (v) and shall contain both an attestation by a qualified mechanic that the catalyst has been replaced and the O₂ sensor has been replaced, if necessary, and that both parts are functioning properly, and a copy of the invoice for parts and labor.
