If you can prove the origin of the materials of your production in the European Union, you have the right to import them with the tax rate 0 or a reduced tax rate. The use of this preference calculation automatically leads to a reduction of your offer price compared to your competitors and opens up competitive advantages for you compared to other suppliers. For a correct preference calculation, it is necessary to check across all stages of processing which materials were manufactured in the EU. With SAP Global Trade Sevices, you have the option of using configurable bills of materials. These are analyzed in the system and the product's preference eligibility is checked. Use the preference calculation and secure advantages in the sales process and improved market access.
