The KA Premium Edition Sales Crates are not working as intended, will be fixed with the next hotfix.

from the daybreak games forum:
The PE sales crates are not able to be placed into the broker slots. They don't have any examine description stating they are sales crates and act only as a house item.
-- RadarX: This is currently a known issue and should be resolved in an upcoming hotfix.
