"Approved" in OSHA rules is not the same as in NEC rules. In OSHA that word requires the use of a listed product. In the NEC it only requires it to be acceptable to the AHJ. In this case, I would not expect that the unlisted conduit would be acceptable to the AHJ because of the specific requirement in 350.6 that requires the conduit to be a listed product.
