This question has been asked in KudoZ. 冲货是营销渠道中的常见现象，不仅发生在同一国家不同的市场之间，而且发生在国际贸易中。人们在日常生活中所说的“水货”，就是来源于国际贸易中的冲货或窜货行为。在国际贸易中，它被称为“平行进口(parallel importing)”或者“灰色营销(gray marketing)”。

The same question has been asked in KudoZ.

Parallel imports are imports of a patented or trademarked product from a country where it is already marketed. For example, in Mozambique 100 units of Bayer's ciprofloxacin (500mg) costs US$740, but in India Bayer sells the same drug for US$15 (owing to local generic competition). Mozambique can import the product from India without Bayer's consent.
Sometimes referred to as “grey market” imports, parallel imports often takes place when there is differential pricing of the same product - either brand-name or generic drugs - in different markets (usually owing to local manufacturing costs or market conditions).
