孟加拉信用证交单单据

有哪位大大做过孟加拉信用证的麻烦帮帮忙，46A里面有一些单据要求实在不知道怎么整，做了6年孟加拉信用证了，每次都被莫名其妙地扣了好多钱。

B) YOUR SIGNED INVOICE IN 08(EIGHT)CERTIFYING MERCHANDISE TO BE OF CHINA ORIGIN. 是不是写上这句话在发票上面就可以了？ “WE CERTIFY THAT THE  MERCHANDISE IS OF CHINA ORIGIN ”

G) COUNTRY OF ORIGIN MUST BE MENTIONED/EMBOSSED/PRINTED ON

​THE BODY OF THE PACKAGE/ CONTAINER. A CERTIFICATE TO THIS

EFFECT FROM BENEFICIARY MUST ACCOMPANY WITH THE SHIPPING

DOCS. 这个A CERTIFICATE TO THIS EFFECT FROM BENEFICIARY MUST ACCOMPANY WITH THE SHIPPING DOCS. 单据谁有模板吗

我的疑问就是动不动就一个CERTIFY或者CERTIFICATE,谁能帮忙提供一个模板吗？感谢
