Further to Olin's answer:
FCC part 15 is the U.S. requirement. For Canada, there's an largely identical requirement set by Industry Canada called ICES-003, based on CSA standards:
- C108.8-M1983, "Electromagnetic Emissions from Data-Processing Equipment and Electronic Office Machines"
- CAN/CSA-CISPR 22-96
The Canadian boilerplate text that's equivalent to the FCC part 15 statement reads like this:
This Class A/B digital apparatus meets all requirements of the Canadian Interference-Causing Equipment Regulations.
Cet appareil numérique de la classe A/B respecte toutes les exigences du Réglement sur le matériel brouilleur du Canada.
As with FCC part 15, an unintentional radiator doesn't require a test report - you must ensure that it complies.
I believe that if there is a compliance issue with the product, you as the seller will be in the focus of the governmental scrutiny. I doubt that you'd be able to negotiate that responsibility away from yourself and put it on your supplier, but if they have any test reports for the product, it would be good to have a copy as a first line of defense.
