What is referred to as dunnage in cargo securing terminology?

Dunnage refers to loose materials that are employed to support and protect cargo during transportation. This term is commonly used in logistics and shipping to describe items such as wood, foam, or other cushioning materials that fill empty spaces within a shipping container or cargo hold. The primary purpose of dunnage is to prevent movement of the cargo while in transit, thereby minimizing the risk of damage from shifting or impacts.

In contrast, tools used for securing loads are typically considered distinct from dunnage as they might include straps, chains, or ratchet tie-downs that physically hold cargo in place. A specific type of tiedown specifically indicates a method or product designed to secure loads as opposed to providing support or protection. Loading equipment usually refers to machinery or devices used to load cargo but does not encompass the protective role of dunnage.
