The Census counts 10 establishments in Charleston County across the classes this site tracks.
This is a small published count: with fewer than 30 establishments, county figures say little about local supply, so lean on the South Carolina capacity figures and treat the numbers here as context only.
South Carolina overall: 462 establishments across the five classes, of which machine shops are the largest. Charleston County sits below the state's typical county for these classes.
