Furious garment and knitwear manufacturers and exporters in Bangladesh are set to sue the government after it imposed a shock ban on all yarn imports through land ports.

Officials from the Bangladesh Knitwear Manufacturers and Exporters Association (BKMEA) and the Bangladesh Garment Manufacturers and Exporters Association (BGMEA) claim the ban will devastate the country's export-oriented garment business.

At a press conference on Friday, they are expected to announce plans to take legal action against the government and ask a court for an injunction against the ban.

The government said it had imposed the measure as part of a crackdown on smuggling, poor quality yarn imports and widespread abuse of bonded warehouse licences.

However, the ban has been warmly welcomed by officials from the Bangladesh Textile Mills Association (BTMA) who had called for urgent government action.

"This (ban) would enable the government to detect smuggled yarn very easily and also stop inflow of yearn with false documents," it said in a press release issued through Worldsources Inc.

"The BTMA urged the Ministry of Home Affairs to arrange setting up of special check points and to encourage the law enforcing agencies to remain vigilant.

"BTMA assured all users that this measure would not affect supply of yarn in any way. Currently BTMA Mills have sufficient stock and production capabilities to meet local requirement as well as required export demand of yarn."
