Wet Cargo

Wet Cargo (WET) is cargo containing liquids or from which liquids may ooze out because of their nature, excluding dangerous goods. This special cargo category requires specific handling requirements including packaging, labeling, documentation and handling through the transport chain. Packaging must be secure and capable of maintaining the shipment in a totally leak-proof condition, allowing for variations in atmospheric pressure and rapid changes in temperature. Standard IATA labeling requires "wet cargo" labels on packaging along with orientation markers like "this way up."

A Lufthansa Cargo shipment (AWB 020-12345678) transporting fresh Chilean salmon from JFK to FRA uses leak-proof styrofoam containers with ice packs, requiring WET handling codes and waterproof cargo absorbent sheets in the ULD. An Emirates SkyCargo shipment (AWB 176-87654321) carries live Maine lobsters from BOS to DXB in water-filled containers, necessitating WET cargo procedures including upright positioning and spill containment during loading.

What specific labeling is required for Wet Cargo shipments under IATA regulations?

Wet Cargo must be labeled with standard IATA "wet cargo" labels plus "THIS WAY UP" orientation marks on at least two opposite sides of each package. The orientation marks must be color durable (red or black) meeting IATA standards, and containers must be stowed in upright position with seals at the top to prevent dripping.

Where can I find the official cargo handling codes for Wet Cargo in IATA documentation?

The WET cargo handling code and related special handling codes are found in Appendix D of the IATA Perishable Cargo Regulations (PCR). The 2025 edition moved all cargo handling codes to the Nomenclature section for easier reference by cargo handlers and freight forwarders.
