Certificate of Materials Origin (CMO)

Yes, Portland Bolt will provide CMO paperwork for DOT projects in the US.

The purpose of a CMO is to document the origin of materials used on a construction project. A CMO is required under the Buy America Act and applies to all federally funded highway construction projects. A CMO is used to certify that all steel or iron materials and manufacturing processes, including protective coatings, for the domestic materials occurred in the US.

Portland Bolt will always provide material test reports (MTRs) along with the domestic fasteners that we manufacture. However, state DOTs may also require a CMO in addition to the certification documents in order to comply with the Buy America Act.
