To import goods into Switzerland, the following are generally required: 1) Commercial invoice with value, origin and detailed description of goods; 2) Packing list with weights and dimensions of each package; 3) Transport document (CMR for road, B/L for sea, AWB for air); 4) Preferential origin certificate (EUR.1 or invoice declaration) for reduced duties; 5) Any specific certificates required by the goods type (phytosanitary, veterinary, CITES, conformity certificates, CE marking). Import declarations are filed via the Passar system (progressively replacing e-dec). BAZG may require additional documentation depending on the type of goods and country of origin.
