要貼啊，private label產品也要貼：
"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)."

從咱們國內寄出的產品都要帶有產地標識，不然到時候出問題就麻煩了：

對啊，好像是說在產品上面要有logo和private label的商品名，而不只是在外包裝上印logo，或者在產品上貼個貼紙就了事。。。
