If goods are in a closed container, what must be indicated on the box?

When goods are in a closed container, it is essential to indicate the IRQ (International Reference Quantity) on the box. The IRQ serves as a standardized reference that helps in identifying the quantity of goods inside the container without needing to open it. This is particularly important for customs and regulatory compliance, as it streamlines the inspection process and ensures that the correct information about the contents is readily available.

Additionally, indicating the IRQ can facilitate significant operational efficiencies in logistics and inventory management. It plays a crucial role in international trade, ensuring that all parties, including shippers, receivers, and inspectors, have access to consistent and clear information about the contents of the cargo, which can aid in preventing disputes or misunderstandings.

While invoices and receipts are also critical documents in the shipping process, they are not necessarily marked directly on the container itself, nor do they provide immediate visual identification of the container's contents. Warning labels may be necessary for certain hazardous materials, but the IRQ specifically addresses the need for quantitative information about the goods within a closed container.
