Work wear and sportswear maker Carhartt is to shut its Dover, Tennessee, sewing plant after increasing imports affected its business.

Carhartt said laws allowing in more garment imports had, and will continue to, change the company's trading.

Vice president for manufacturing, Phil Edlin, referred to the recent passing of the CAFTA-DR deal and the expiration of the global quota system.

The 11-year-old Dover Plant is due to close down on 31 March.

It was not reported how many workers will be affected by the decision.
