Final answer:
A direct sales force is often necessary for big ticket industrial products due to the complex sales process that requires significant investment, customization, and technical support.
Step-by-step explanation:
A direct sales force may be required in a foreign country, especially for big ticket industrial products. In the context of global trade, companies dealing with high-value industrial goods typically need a dedicated team to manage personal relationships, technical support, and after-sales service. This need arises because these products often require significant investment and customization, making each sale a complex process involving negotiations and a detailed understanding of customer needs.
In contrast, products like low-technology items, personal care products, nonmechanical goods, or traditional hand-made goods may not require such an extensive direct sales force, often because these items can be more easily sold through distributors, retailers, or online platforms where the sale doesn't rely as heavily on long-term client relationships or technical support.
