This paper explores the optimal product decision when consumers have different perceived quality of parallel imports and remanufactured products in a supply chain system that contains a brand owner and a parallel importer. By establishing a parallel importer market invasion model under remanufacturing and no remanufacturing scenarios, we analyze the interplay between remanufacturing and parallel imports. It is found that no matter how consumers perceive the quality of the remanufactured products, remanufacturing can help brand owner cope with gray markets. The market invasion of parallel importers will promote the remanufacturing of brand owner. In addition, when remanufacturing cost saving degree is relatively low, the higher the perceived quality of the remanufactured products, the lower the price of the parallel import products, the smaller the parallel import vollume, and the lower the profit of the parallel importer.
