WWT (Wind and Watertight) = Extra Used
WWT, or wind and watertight, refers to cargo containers that are structurally sound and free of holes, leaks, and cracks, allowing them to withstand heavy winds and rain. This basic level of container condition ensures that no wind or water can penetrate the container when used as intended. WWT containers are suitable for storage and serve as the starting point for further classification in the cargo container industry.
