請幫忙!! 出口文件問題, thanks

客人要求以下文件:

1. Commercial invoice in triplicate stating the name and address of manufacturers / processor of the goods, certifying origin of goods and contents to be true and correct of which original copy must be duly certified by the chamber of commerce in the exporter's country.

2. Certificate of origin in triplicate, original of which must be issued / certified by the chamber of commerce in the exporter's country, showing the name and address of manufacturers and stating the country of origin.


第二點應該是做一份C.O. 再在香港加簽, right? 但c.o. 不會一式三份的, 可以怎辦?
第一點是invoice 一式三份的, 但要加簽??
