Over-length Cargo

Over-length Cargo refers to cargo whose single-piece length exceeds the standard limits of conventional containers or transport vehicles during transportation. Typically, the internal length of a standard container is about 5.9 meters (20-foot container) or 12 meters (40-foot container). If the cargo length exceeds this limit, it is considered over-length cargo. It is commonly used for large machinery, steel pipes, timber, vehicles, etc. Precautions include: applying in advance to the shipping company or airline for special loading permission, which may incur an over-length surcharge; confirming the suitability of the transport equipment (such as flat racks, open-top containers, breakbulk vessels); securing and lashing the cargo to prevent shifting; and accurately declaring dimensions and weight during customs clearance. Unlike 'overweight cargo,' over-length cargo focuses on excessive length, while overweight cargo focuses on excessive weight; compared with 'oversized cargo,' over-length cargo emphasizes only the length dimension, whereas oversized cargo may simultaneously involve excess length, width, and height. Foreign trade practitioners should communicate with freight forwarders in advance and allow sufficient operating time to avoid rollover or delays caused by size issues.
