But economists note that domestic manufacturing of motor vehicles and electronic products is heavily reliant on imported raw materials such as steel and aluminum and complex components such as semiconductors and computer chips.

An iPhone for example may contain chips that were designed in the US, manufactured in Taiwan, Japan or South Korea, using raw materials like rare earths which are mostly mined in China.

British Steel's blast furnaces are set to continue running with a delivery of enough raw materials to keep them alight for the "coming weeks" due on Tuesday, the government has said.
