Products are also inspected and certified at export warehouses for international shipments. South Carolina's Grain Inspection Service is headquartered at the export elevator in North Charleston. Inspectors and their staff, sample and grade grain incoming to the port in trucks and rail cars and grade and monitor the grain loaded for export on ships. Ships are inspected for cleanliness, and contamination before loading begins. During loading inspectors weigh, sample and insure proper movement of grain to the ship.
Inspectors also carryout inspections throughout the state on a call basis.
