原產國等於制造國嗎？

The answer is not necessary.

Country of origin is relative a term used in customs clearing. However, as a fact, the country of origin does not necessary represents the country where the products are made in the majority.

For example, in the past, the U.S. has imposed a quota system to all textile products from Mainland China. In order to avoid that system, manufacturers made all the parts in the Mainland and ship all the parts to Hong Kong for final assembly. In this case, manufacturers can claim "Made in Hong Kong" to avoid the quota system

And this is the exact reason why country of origin does not necessary equivalent to the country of manufacturing.

原產國。就是產地。不管原料是哪裡的。只要在該國經過加工或生產包裝後。該國就是原產國。
