A packing list is a commercial document that details the contents of each package in a shipment. Unlike the commercial invoice which shows values and sale conditions, the packing list describes the physical composition of the shipment. It is essential for customs clearance, warehouse logistics and delivery verification. Required information: reference to the corresponding commercial invoice; sender and consignee details; number and type of packages (pallets, cartons, crates, drums); contents of each package (description, quantity, items); dimensions of each package (L × W × H in cm); net and gross weight of each package; total net and gross weight; total volume in m³; package marks and numbers. The packing list is required by customs to verify goods during inspections, calculate Swiss weight-based duties, and determine transport costs. Common mistakes: packing list not matching physical packages; approximate weights (Swiss customs requires precision); unnumbered packages; omitting pallet weight.
