Historically, Kerala's industrial structure has been dominated by traditional industries characterized by:
Small-scale operations: Many units were and still are in the unorganized or cottage industry sector.
Resource-based production: The industries primarily depended on the abundant natural resources of the state, such as coconut, cashew, spices, clay, and timber.
Low-tech methods: The primary traditional industries like coir, cashew processing, handloom, and handicrafts (like bell metal and wood carving) typically involved labor-intensive processes with relatively low levels of technology and capital investment.
While some large-scale, modern factories were established during the pre-Independence era (like FACT, Travancore Rayons, and a few textile and paper mills), the majority of employment and industrial character historically stemmed from these traditional, resource-based, and small-scale sectors.
