CHARLESTON, SC (WCSC) - More than 30 tons of chemicals used to make drugs were found at the Port of Charleston.
Drug Enforcement agents say it could lead to an even bigger drug ring.
The DEA says the chemical, benzaldehyde, was in 55-gallon drums that filled two shipping containers.
Authorities took the chemicals last week when the ship called at port.
The chemical is used in methamphetamine.
Resident Agent Jason Sandoval says that amount could make more than 60 tons of meth.
We're told the shipment started in India and was passing through Charleston on its way to Mexico.
Sandoval says the chemical was not properly declared and investigators believe it was on it's way to cartel drug manufacturers.
Investigators are now working to identify anyone connected to the shipment.
