Final answer:
An Export Management Company (EMC) serves as the export department for non-competing manufacturers, enabling them to participate in intra-industry trade by exporting intermediate goods.
Step-by-step explanation:
An independent marketing intermediary, which acts as the export department for two or more manufacturers with non-competing product lines, is known as an Export Management Company (EMC). EMCs play a crucial role in facilitating intra-industry trade by enabling manufacturers to reach international markets. By handling the complexities of exporting, EMCs make it possible for companies to offer their intermediate goods to businesses involved in the production process in various parts of the world. This arrangement is particularly beneficial for businesses not powerful enough to dictate policy or handle international logistics themselves, but who are looking to engage in the expanding global marketplace.
