中譯英 唔該

How long is the certificate valid? Can it multiply to use 3 times for the same product? Do we have to sumbit original certificate to the customs everytime we export? Or we can just provide copy. If original is needed, is that mean we have to apply this certificate everytime we want to export our product? Any way out?

1. 請問證書可以用多久? 是否3單貨不同時間出口也能用同一個證書?

How long is the certificate valid? Is it possible to use the same certificate for three different orders with different shipment date?

2. 每次貨出口需要報關時, 是否需要證書的正本? 還是只是副本就可以?
Is it necessary to present the original certificate when we declare every shipment?

如果需要正本, 是否我們每次出貨前需要申請證書? 有沒有其他方法?
If the original certificate is required, we have to apply the certificate for every single shipment, don't we? Is there any other option?
