请问FBA的private label产品要贴上made in China标签吗？

要贴啊，private label产品也要贴：
"Prior to importing your goods into the United States, you should ensure the overseas supplier has marked the goods with the country of origin. For example, goods originating in China should be marked "Made in China". The marking must be legible and permanent enough for the ultimate purchaser to be made aware of the goods origin.
The ultimate purchaser is the person who will last purchase or receive the article in the condition in which it was imported. That could be a consumer (one who buys), processor (one who further processes materials or recipient (receiver of a gift)."

从咱们国内寄出的产品都要带有产地标识，不然到时候出问题就麻烦了：

对啊，好像是说在产品上面要有logo和private label的商品名，而不只是在外包装上印logo，或者在产品上贴个贴纸就了事。。。
