He has the FDA certificate on hand, the FDA certificate is very important for US market at present. We have ever sent a laser machine to USA without the FDA, in result the goods was impounded in the custom. The officer of the US custom told us that there are only 2 ways to solve the problem. first one is to destroy the goods by them, the second one is to return the goods to us by FedEx, but the high delivery cost is cost by us. Now the FDA ruls are much more strict.
So, friends from US who are preparing to buy laser machine must make sure that you, or the supplier(manufacturer) must have the FDA certificate in hand, otherwise you will lose a lot and will get nothing, except wasting your time.
Just an suggestion, take it or not, it up to you.
