Interested in offering us your manufacturing services or parts?

Suppliers are required to have active certification for ISO 9001:2015 and/or IATF 16949:2016 and are encouraged to obtain ISO 14001:2015 certification and maintain it during the business relationship with Westport Fuel Systems. Evidence of this certification must be provided to Westport Fuel Systems in the initial supplier evaluation process.
