1.signed commercial invoice是手签，那还需要盖章吗？2.DESCRIPING GOODS AND CERTIFYING AT THE SAME TIME THEIR ORIGIN, CONTENTS ARE TRUE AND AUTHENTIC AND THEIR PRICES AS CORRECT AND CURRENT AND THAT IT IS THE ONLY INVOICE FOR THE MERCHANDISE DESCRIBED THEREIN这是对发票的要求。你能翻译的话，你就能独自操作信用证了。

1、无须手签。2、描述货物的同时证明其原产地、内容是真实可信的、价格是正确的与最新的，并且这是此处描述的货物唯一的发票。在描述货物及其原产地后，后面的内容照抄在发票上“CONTENTS ARE TRUE AND AUTHENTIC AND THEIR PRICES AS CORRECT AND CURRENT AND THAT IT IS THE ONLY INVOICE FOR THE MERCHANDISE DESCRIBED HEREIN”THEREIN改成HEREIN就行。

签了名后，加盖公章，更具有效力
