I like Laurent's translation, except that "certifiée" makes it sound like there's a certification process or a list of certified/pre-approved suitcases. There isn't; there are just TSA rules, and if your suitcase complies with those rules or makes it easier for you to comply with rules (e.g. the way it holds your laptop makes it easy for you to present your laptop correctly at the security checkpoint, or the way it locks allows TSA to easily unlock it), then it's "TSA-compliant."
