Is it permissible to engage in a business based on selling international goods that were imported illegally?

If the intention is to smuggle bags illegally, then the law prohibiting this should be considered. If it harms the country and its people, then it is not permissible to bring them in. Otherwise, it is permissible.

However, if the intention is to sell them at a lower price, and if there is a fixed market price that harms merchants, then the seller should be told either to raise the price or to sell them outside the market. Otherwise, there is no harm in selling them at any price and in any place.
