Cuddalore
Cuddalore anchors the SIPCOT chemicals industrial estate (one of Tamil Nadu's largest chemical clusters), runs a long-standing cashew-processing cluster (along with Pudukkottai + Tiruvannamalai supply), and hosts the historically-significant Cuddalore Port. Coastal blocks share marine fisheries with Nagapattinam.
Salem
Salem is a district of clusters: India's largest sago/sabudana production base (~80% of national output, ~66,000 MSME units across all sectors), a stainless-steel hub centred on SAIL's Salem Steel Plant, ~40.5 mt magnesite reserves at the Chalk Hills (TANMAG), silver-anklet workshops in Sankari, and a deep ITI/diploma talent pool feeding all of the above. Strong rail and NH-44 connectivity to Bangalore, Coimbatore, and Chennai.
