As economic globalization increases, many big brands have established overseas factories to distribute their products globally. Although these products sell under the same trademark, they may differ in technical specifications and pricing. As a result, some traders buy low and sell high, arbitraging between low-price countries and high-price countries. In contrast to counterfeit goods, parallel imported goods are authentic because they originate from the genuine producer and bear authentic trademarks.
