I have never done any business with "Comex LLC". However, this may help.
There are several "Comex LLC" listed on the registry. I found the following:
1.
http://www.sectorpages.com/r/11667/Comex-LLC.html>
www.comex.dp.ua
2. The address (46 Glynn Court, Parlin-NJ 08859 listed on "Alibaba" is registered to the following companies:
Nucleus (Charles Logiudici, Director)(Kenneth Johnston, Secretary) 732-238-8338
Peal Group of Industries (Peter Billia, President) (Andrew Lafrattes, Secretary) 732-238-8338
As you can see, the address house several companies, with the same telephone number.
My system is currently down and I cannot check on New Jersey's business registry to confirm if COMEX is indeed registered as a Limited Liability Company and licensed to conduct business in that state.
Maybe later I may be able to check. Until then, this is all I can provide you.
Good hunting.
