The purpose of the Steel Import Licensing System (SIMA) is to provide the public with timely, detailed statistics on steel imports.
There are some differences between SIMA data and the Census data mostly due to import date issues.
Census uses 'statistical months', which are based on the 'date of release' of the import.
Thus, if goods arrive too late in the processing cycle, they are placed in the next month’s set of data.
SIMA month of data, however, represents an aggregation of all submitted licenses that report that month as the expected month of Import.
Additionally, SIMA data are not put through the same rigorous statistical tests and scrubbing as the Census data.
