The EF6000 is undergoing NSF recertification. As such I will not carry it until after it completes the process.
EF6000 Undergoing Recertification
So, the EF6000 is being recertified by the NSF. This means that production at the factory has been halted while the NSF complete their testing of a sample EF6000.
Usually, this happens seamlessly in the background. In fact, the other EF Series products are still certified so this halt doesn't apply to them.
Sorry for the inconvenience, but I'd rather not run the risk of selling an uncertified product
