For goods that you have brought into the customs territory of the Union, you must submit a declaration for temporary storage at the latest at the time of presentation. This is done via the ATLAS sub-procedure Summarised declaration (SumA) at the customs offices. SumA is used at all sea and airport customs offices as well as inland and border customs offices.

You can use the Internet Status Information (ISA) to call up information about your SumA processes online and check the processing status of the individual items. You can also have the data output in structured form and process it further in your system.

To use the ISA, you submit an informal application to your responsible customs office and name a responsible person. To prove your eligibility, you must identify yourself with your EU-wide economic operator registration and identification number (EORI number). The responsible person is created by the customs office for your EORI number as an administrator and can thus set up further accesses with their own password to your EORI number via the ISA participant administration.
