关于大使馆认证的发票问题

大家好；现在有个问题是： 客户的信用证上写的是：SIGNED COMMERCIAL INVOICES IN SIX COPIES, ISSUED BY BENEFICIARY ON THEIR LETTER HEAD, OUT OF WHICH THE ORIGINAL AT LEAST MUST BE CERTIFICATED AND LEGALIZED, INCORPORATING THE FOLLOWING CLAUSE:INVOICES MUST BE CERTIFIED BY C.C.P.I.T. AND LEGALIZED BY IRAQI EMBASSY.


我知道要出6份发票，我给客户6份正本的问题吧 ？ 他说还要做贸促会认证和使馆认证，这个贸促会认证和使馆认证要做几份啊？我要交给贸促会6份吗？让他们做6份贸促会认证和大使馆认证还是只做一份就行
