A customs tariff number is not mandatory but strongly recommended to avoid longer delays.

If there is no customs tarrif we need an accurate description of the goods on the invoice. Inaccurate descriptions of exported goods are not accepted and will cause delays in customs clearance. The description of goods must include the name of the items, quantity per item, composition, value per unit and intended use. The use of general terms such as "samples", "parts" or "spare parts" are not to be used for customs classification.
