JCB is set to double the size of a new factory currently under construction in Texas, as the company confirmed that newly-announced tariffs will affect its business in the short term. JCB has been manufacturing in the USA for 50 years and last year bought 400 acres of land in San Antonio after it said it recognised the need to produce more machines in North America, where the company’s existing manufacturing plant in Savannah, Georgia, has operated for 25 years and employs around 1,000 people.
