A Technical Standards Order (TSO) is a document issued by the FAA. The current issue is TSO C90 (c). Each ULD must carry a TSO marking (a plate or a tag for containers, or engraved for pallets) that contains the manufactures name, the date of manufacturing, a part number, and reference to the TSO under which the ULD was certified. At the moment an equivalent European TSO is issued by the EASA (ETSO C90 c).
