Taking full ownership of Shintech and integrating PVC around a Texas location (1976)
Location as a given, integration as a choice
The core of this decision was neither technology nor sales but the choice of where to put the plant — somewhere the raw materials were cheap. Japanese PVC makers, importing every input, could polish their processes as much as they liked and still never reach the advantage conferred by Texas rock salt and natural gas. Shintech’s half-century quietly demonstrates a principle of manufacturing: it is precisely in undifferentiated commodities that location decides competitiveness. The climb from thirteenth place owed less to managerial brilliance than to the opening move of choosing a place where winning was possible.
Location, though, is only a given; what turned it into an advantage was taking full ownership — and with it complete authority over investment — and then pulling external dependencies inside one at a time. Each stage was an independent investment decision, yet in retrospect they form a single line. Holding everything from raw material to finished product is one of the few sources of stability in a materials industry of violent price swings. In a place blessed with cheap resources, how far can you reduce what you leave to others? The question remains open for manufacturers facing renewed uncertainty in resources and energy today.
