What is the purpose of Document Modifier for shipments with part numbers?

The purpose of the Document Modifier for shipments with part numbers is to identify products using part numbers for proper delivery. This ensures that specific items are accurately tracked and delivered to the correct destination, minimizing errors and facilitating effective inventory management. Using part numbers allows for a more streamlined shipping process, as stakeholders can quickly verify and reference the exact items being shipped, which is particularly important in military logistics where precision and accountability are critical.

The other options do not capture the core intention of the Document Modifier in this context. International shipments and custom orders, while important aspects of logistics, are addressed through different identifiers or documentation processes. Similarly, additional delivery charges pertain to financial aspects and are not the focus of part number identification in the shipment process.
