Factories and corporate offices cover much of Nar Shaddaa's surface, and the Lower Industrial Sector houses some of the oldest industrial facilities and warehouses still in use‒some dating back hundreds of years to the Evocii's construction of the city. But layers of rust haven't prevented new tenants from making use of these resources.
The Empire operates a series of front corporations out of Nar Shaddaa, concentrated in the lower levels. These companies are used to provide experimental weaponry and technologies to the Empire at a discount rate, facilitate the slave trade that fuels Imperial labor across the galaxy, and serve as a clearinghouse for cargo, credits and individuals being moved through non-Imperial space.
The Hutt Cartel also maintains an interest in the sector ‒buildings not leased to the Empire store spice, adrenals and implants. The warehouses are heavily guarded, and some are rumored to hide the special projects of individual Hutts from their rivals.
