In international trade, importers import similar goods with the same trademark from abroad without the permission of their own trademark owners or trademark users, and these goods are legally authorized to produce. If the parent company is a trademark manufacturer and the subsidiary company is a trademark management company, there is an internal relationship between them. At this time, the goods imported from the parent company are not typical trademark parallel imports.
