Customs duty calculation lets you calculate the various values that you need to process imports and exports based on logistics documents. The decisive factor is duty calculation, which you can (or must) perform independently based on country-specific requirements. The system calculates customs duties from the customs value as the tax base and from the duty rates applied to the customs value.

The data you need for the customs value can be transferred from the logistics documents in an integrated feeder system or entered manually in the documents for customs processing. For example, the system takes the invoice price from logistics documents in the feeder system. You can implement Business Add-Ins (BAdIs) to include other values in customs value calculation. To calculate the duties, the system uses the geographical constellation in the business partner relationship and the product classification to determine the relevant customs duty rates and applies them to the customs value as the calculation base.

The system can calculate additional values, depending on the process. For example, you can calculate the statistical value of a transaction as a basis for statistics declarations. Within the European Union (EU), the system displays the import turnover tax as additional information after customs duty calculation.


You have configured customs duty calculation in Customizing for Global Trade Services (GTS), using settings in Customizing activities such as the following   Global Trade Services   Customs Management   Calculation of Customs Duty  :

  • Define Type of Customs Duty

  • Define Customs Duty Framework

If you want to transfer additional values from feeder system documents, you can implement the BAdIs in the feeder system to transfer additional values, as well as BAdIs to insert additional data in the GTS system.

For more information about the Customizing settings and the BAdIs in the feeder system and the GTS system, see the Configuration Guide for Customs Management. It is available at the SAP Service Marketplace under the following path:   Download   Installation and Upgrades   Entry by Application Group   SAP Application Components   SAP Global Trade Services (GTS)   SAP GTS <Release>   Installation and Upgrade.  


You can use customs duty calculation in the following customs processes:

  1. Customs import processing

    • Customs duty calculation in import documents as the basis for customs declarations prior to goods receipt (see Customs Duty Calculation for Customs Declarations Prior to Goods Receipt)

      You can use purchasing documents as the basis for customs import declarations that you or the system create prior to goods receipt. When you forward the purchasing documents to the GTS system, the system can create customs documents as replicates of the purchasing document. Based on this customs document data, the system then calculates the preliminary customs value and the resulting duties during customs duty calculation. You can use the replicate of the purchasing document to create customs import declarations prior to goods receipt, using a worklist.

    • Customs duty calculation in customs declarations prior to goods receipt (see Customs Duty Calculation in Customs Declarations prior to Goods Receipt)

      Based on the replicated purchasing documents, for which you have transferred the prices to the GTS system for Customs Management (optional: along with quantity data from inbound delivery documents), you can calculate the preliminary import costs.

    • Customs duty calculation in customs declarations after goods receipt (see

      Customs Duty Calculation in Customs Declarations after Goods Receipt)

  2. Customs export processing (see Customs Duty Calculation in Customs Export Processing)

    Customs duty calculation in customs export processing calculates the customs value that you send to the customs authorities in the customs export declaration. The customs authorities forward the statistical value, as well as other relevant data, to the responsible statistics authorities.

  3. Simulate customs duties (see Simulating Customs Duty Calculation)

    You can calculate the potential customs duties for a combination of country of departure, country of destination, and other relevant parameters and compare up to three different alternatives.
